Battery Standby Issues...

Hi, I've read about several battery issues posted by others, and usually drainage issues involve leaving wifi on, etc. First of all, I heart my touch, functions perfectly (knock on wood). However, sometimes (but not that often) when I leave it on standby (with no wifi on), the next time i turn it on it either doesn't turn on at all (b/c its drained), or gives the empty sign. I find it happens mostly when I leave it on standby for a long period of time (30 hours+ for example). Is standyby not meant for very long periods?? And it's also a bit chilly in here sometimes, but not too cold. Is this normal?? PLZZ tell me it's not a defective battery problem, b/c it has been soo good so far. Thanks a bunch.. @.@

I have a similar issue. I got mine yesterday -- and my cell standby is consistently at 35-40% and my time without signal has never been over 10%. When I got it yesterday, I had to recharge it twice, and I don't think I used it more than an average user would. So anyway, I recharged it and took it off the charger at 9-ish this morning and I was down to 50% battery usage after 4 hours. The only thing I'd done was text a few times and play Angry Birds for 10 minutes tops. I somehow managed to make it last the rest of the day, but that was because I barely touched it and only texted a total of maybe 50 times.
I haven't tried the *228 option yet because I'm afriad I'll do something to mess up my phone further. But if someone could help both of us out, that would be awesome. I'd hate to take this phone back because I love everything about it except for the battery life. I mean, it's still under warranty and I have another what, 12 days to take it back to the store, but that's a huge hassel that I really wouldn't have liked to deal with in the first place.

IPhone 4S Battery Life: Best solutions and procedures for 1st time user: 1-Do you have a battery life issue (learn first what the usage time spec is about) 2-What can you try to remedy the situation without reading 500 pages of posts

What follows is a grouping of some of the most fruitful procedures - from what I've seen in the biggest battery life issue thread - and some background information and discussion for solving or improving the battery life with the iPhone 4S and may be applicable also to devices on which iOS 5.0/5.0.1 has been applied. Credit goes to the respective users who contributed this information to the forum and they should be commended for doing so. This is not a final listing. The goal here is to provide a first stop sort of knowledge base document for newcomers instead of having them perusing the never ending threads where the wheel is reinvented on every page...
Please don't post your questions, usage screenshots, or claims that it worked or not for you or anything here except PROCEDURES/DEBUG STEPS/SOLUTIONS or improvements to the procedures already listed here. Try to use point form and to be as concise and clear as possible. Hope all this helps.
Thank you and good luck!
General info and specs
First, take a look Apple's battery tips, info and specs(obligatory reading for all Iphone 4S users - read it once and for all):
http://www.apple.com/batteries/iphone.html
http://www.apple.com/batteries/
... you didn't read it? loll Always remember this i.e. the definition of "usage":
Usage: Amount of time iPhone has been awake and in use since the last full charge. The phone is awake when you’re on a call, using email, listening to music, browsing the web, or sending and receiving text messages, or during certain background tasks such as auto-checking email.
I'm still not convinced you read the links so here's what Apple has to say in terms of fine tuning your battery life:
Optimize your settings
Depending on how they are configured, a few features may decrease your iPhone battery life. For example, the frequency with which you retrieve email and the number of email accounts you auto-check can both affect battery life. The tips below apply to an iPhone running iOS 5.0 or later and may help extend your battery life.
Minimize use of location services: Applications that actively use location services such as Maps may reduce battery life. To disable location services, go to Settings > General > Location Services or use location services only when needed.
Turn off push notifications: Some applications from the App Store use the Apple Push Notification service to alert you of new data. Applications that extensively rely on push notifications (such as instant messaging applications) may impact battery life. To disable push notifications, go to Settings > Notifications and set Notifications to Off. Note that this does not prevent new data from being received when the application is opened. Also, the Notifications setting will not be visible if you do not have any applications installed that support push notifications.
Fetch new data less frequently: Applications such as Mail can be set to fetch data wirelessly at specific intervals. The more frequently email or other data is fetched, the quicker your battery may drain. To fetch new data manually, from the Home screen choose Settings > Mail, Contacts, Calendars > Fetch New Data and tap Manually. To increase the fetch interval, go to Settings > Mail, Contacts, Calendars > Fetch New Data and tap Hourly. Note that this is a global setting and applies to all applications that do not support push services.
Turn off push mail: If you have a push mail account such as Yahoo! or Microsoft Exchange, turn off push when you don’t need it. Go to Settings > Mail, Contacts, Calendars > Fetch New Data and set Push to Off. Messages sent to your push email accounts will now be received on your phone based on the global Fetch setting rather than as they arrive.
Auto-check fewer email accounts: You can save power by checking fewer email accounts. This can be accomplished by turning off an email account or by deleting it. To turn off an account, go to Settings > Mail, Contacts, Calendars, choose an email account, and set Account to Off. To remove an account, go to Settings > Mail, Contacts, Calendars, choose an email account, and tap Delete Account.
Turn off Wi-Fi: If you rarely use Wi-Fi, you can turn it off to save power. Go to Settings > Wi-Fi and set Wi-Fi to Off. Note that if you frequently use your iPhone to browse the web, battery life may be improved by using Wi-Fi instead of cellular data networks.
Turn off Bluetooth: If you rarely use a Bluetooth headset or car kit, you can turn off Bluetooth to save power. Go to Settings > General > Bluetooth and set Bluetooth to Off.
Use Airplane Mode in low- or no-coverage areas: Because your iPhone always tries to maintain a connection with the cellular network, it may use more power in low- or no-coverage areas. Turning on Airplane Mode can increase battery life in these situations; however, you will be unable to make or receive calls. To turn on Airplane Mode, go to Settings and set Airplane Mode to On.
Adjust brightness: Dimming the screen is another way to extend battery life. Go to Settings > Brightness and drag the slider to the left to lower the default screen brightness. In addition, turning on Auto-Brightness allows the screen to adjust its brightness based on current lighting conditions. Go to Settings > Brightness and set Auto-Brightness to On.
Turn off EQ: Applying an equalizer setting to song playback on your iPhone can decrease battery life. To turn EQ off, go to Settings > iPod > EQ and tap Off. Note that if you’ve added EQ to songs directly in iTunes, you’ll need to set EQ on iPhone to Flat in order to have the same effect as Off because iPhone keeps your iTunes settings intact. Go to Settings > iPod > EQ and tap Flat.
Usage specs for the 4S - http://www.apple.com/iphone/specs.html:
Talk time: Up to 8 hours (12.5% per hour drain) on 3G, up to 14 hours (7.1% per hour drain) on 2G (GSM)
Standby time: Up to 200 hours (0.5% per hour drain)
Internet use: Up to 6 hours on 3G (16.6% per hour drain), up to 9 hours (11.1% per hour drain) on Wi-Fi
Video playback: Up to 10 hours (10% per hour drain)
Audio playback: Up to 40 hours (2.5% per hour drain)
So a scenario of normal usage could be for example: 4 heavy hours of 3G internet browsing (66.4%), with one hour of call on 3G (12.5%) and 22 hours of standby (11%) = 100%
A battery life issue is a problem where the drain is really out of spec either during usage or standby or both. For example, multi-% per minute drain during usage or a 10% drain per hour during standby is problematic. Browsing the internet on 3G during one hour and losing 16-17% is not.

davidch tips (reset+full discharge recharge):
Go through these steps to address the battery after updating to iOS 5.0.1:
1. Reset all settings (settings app-> general-> reset)
2. Go through initial setup steps (lang, wifi, siri, enable location, etc) and choose setup as new phone (don't worry your apps, data, contacts, mail will still be there). Do NOT restore from iCloud or iTunes (It can copy back corrupt settings)
3. Turn off system location services timezone and iAd
4. Fully discharge battery (tilll it shuts off with the spinning wheel)
5. Fully recharge battery (overnight if possible)
In my experience this improves the Standby battery drain issue significantly in most cases. It reduces drain from 2-4% or more per hr to 0.5% or less. It has worked for many, many users now. If it does not work after a few try's you may have a real battery or hardware issue and should contact Apple. Good Luck!

6. Disable Siri 'Raise To Speak' and REBOOT *( if possible use another camera to verify the                 infrared is off after the reboot).
7. Set emails, icloud and calendars to fetch. ** test. Mines on hourly.
8. If your in a no signal and your phone is saying "Searching..." even after 10mins, reboot while in that area and after 1-2min it should say "No Service". This mainly applies to Verizon customers and improve battery life in these areas.
9. *optional* Goto Settings > General > Network and you will see "Hotspot.." loading something, wait a few seconds and it should say "setup personal hotspot" then exit out.
* I notice a great improvement after disabling this and rebooting. This increased my "screen on" usage or at least helped it. Make the change.
** I have not tested push yet to narrow down the drain but I had this change on my phone. I believe exchange push is responsible for some stand by drain. As for icloud, haven't notice much of a difference. Just try it for a day. My email still came in fast most times. Again still testing, will report back on these..
buxbuster tips(wifi sync, iCloud):
These are my own tested workarounds that worked for my iPhone 4S and seemed to have worked for others as well :
Workaround number 1. Deselect wifi-sync in iTunes and press sync.
If that doesn't work try :
Workaround number 2 : Remove iCloud, reset network settings. ( I guess this won't work for you since you don't have it enabled ).
If both workarounds fail, you can always try to completely wipe your phone. That also solved some of the cases out there.
rolandomerida tips - i.e. buxbuster and additional steps:
Finally, I solved the syncing error loop. My contacts are syncing flawessly again between my devices and iCloud, and yes, the battery stopped draining, which is the main topic here.
I followed instructions from buxbuster (check his workaround a few pages up!) and an additional BIG step to restore contacts and syncing, as seen in a MacRumors forum.
This is what I did:
1. Make a backup of your Address Book, using the vCard option (or both, it doesn't hurt). Save it for later.
2. In your iPhone, delete iCloud account. When it asks, accept both: delete AND delete from my iPhone.
3. Reset network settings. The iPhone will restart, then will ask you to unlock the SIM card.
4.Turn Wi-Fi on.
5. Add the iCloud account again.
That's for Buxbuster's workaround. For some, it might work just like that. My iPhone repopulated from iCloud after step 5, but I still had that "server error" on iCloud. I had to do some extra steps, since my Mac was not syncing to iCloud and couldn't edit anything on my Mac or iCloud. Syncing back had to be fixed, too. If not, the syncing loop would continue from my iPhone, and the battery would drain awfully again.
1. In System Preferences -> iCloud, I turned Contacts off. I chose "keep on My Mac" those contacts, but I got an empty Address Book after a while. And a few minutes later, iCloud contacts were empty and my iPhone also. It is scary at first! Now, before importing that vCard backup...
2. Turn Wi-Fi off. This is important, since your contact-empty iCloud will attempt to wipe your Address Book from your Mac in seconds after importing.
3. Import your vCard backup to Address Book. Just drag it to your blank Address Book window; it asks if you want to import "x" number of cards. Of course, say yes.
4. Turn Wi-Fi on, and then iCloud contacts on again (System Preferences -> iCloud). It will offer to merge your newly populated Address Book with iCloud (which is empty at this point). It should upload every single contact to iCloud, and then to your iDevices. If not, a fifth step would be to import the vCard file to iCloud, but it shouldn't be necessary.
So, with iCloud syncing working correctly, there is no battery draining! Again, that was my particular issue.
I can't tell if this is the single answer to the widely spread battery draining problem, but it sure can be fixed with these workarounds, and yes, Apple should address the problem with a future update, for we affected customers don't need workarounds in the first place
This is the MacRumors discussion:

Miless tips (full 800mb release of 5.0.1 and sanitizing a restore):
As for 4S battery life. Try doing this,
1. Settings>Location Service ... disable all location services you do not need. In particularly Facebook because it drains the battery a lot.
Scroll down to the bottom at Settings>Location services>System Services ... Disable Setting Time zone, location based iAds, Diagnostic & Usage.
2. Settings>Notification>Calendar ... turn off the Notification Centre.
3. Settings>General>Reset ... do Reset All Settings. Doing this will not wipe out your iPhone. It will just Reset the network settings, location warning, keyboard dictionary, etc... but it will clear up some corrupted data there. Generally this will help.
Try these 3 steps first... if it still drains a lot, try the following,
4. Drain your battery down to 1%. Then charge it up using USB from PC ... not the charger. The charger output 1.0 A ( x 5V from USB ... you get 5W power). From PC, output is only 0.5A x 5V = 2.5W power. Charging is slower but trickle charge 4S helps the battery retain its charge better. I think it takes about 3-3.5 hours to charge full from USB/PC compared to slightly below 2 hours using iPhone charger.
If after doing the above still could not solve your battery issues (mine with iOS 5.0 was ok up to step 4, but not iOS 5.0.1).... plug you iPhone to a charger (any charger), from iPhone, access your iCloud ... set it up if you havent. Back up your iPhone data to iCloud. if you do not have enough storage (only 5GB is free), go to details and select the apps you need its data backup, choose only those you really need and leave those unnecessary ones out. Back up your camera roll to your PC/Mac manually as it could be too big to backup to iCloud.... once you have it setup, make sure you are on Wifi ... tap backup to iCloud from your iPhone. It will take a while if the file is huge.
Once backup to iCloud is completed, plug your iPhone to PC/Mac and launch iTunes 10.5.1 (make sure you have 10.5.1)
Click Restore. It will automatically initiate a download of iOS 5.0.1 ipsw for iPhone 4S. Wait for the whole process to finish, ie. download, restore software/firmware.
Once its done, do not set up your iPhone from iTunes. Set it up on your iPhone. Go through the selection. When prompted, select restore from iCloud (from your iphone backup earlier). Keep your iphone plugged into iTunes while restoring backup from iCloud. Because while restoring from iClouds, some data will be synced from iTunes if you plug in, e.g. music, video, etc... unless you bought these content from iTunes store. Apps will be downloaded from App Store from the cloud.
Once it's all done restored. Turn off your iPhone,.. and turn it on again.
Now, hopefully your battery wont be draining so fast anymore. Usually it wont after this. But you need to charge your battery at least 4-5 cycles to stabilize the charge on the battery. I dont know why... but battery life seems to get better and better for me after a few charge cycles after all the above work.
Good luck. Let us know if it works for you.
W. Raider tips (Sirii):
Bottom line for me of things that helped battery life are:
1. Turing off Siri and Rebooting the phone by holding the Home button and Top button down, ignoring the slider, until the phone shut down. (turn off Siri, reboot, and check top front of iPhone 4S against a lesser camera like the front-facing camera on an iPad2 - making sure the IR sensor is off)
2. Fully draining the battery, meaning using the phone until it shuts itself off from a drained battery and then recharging it to 100% about 4, maybe 5 times. I charged it both with a Mac and a wall charger.
Hope this is helpful!

jmm514 remarks (Twitter):
I may have found something. I had Twitter disabled in my notifications, but got a tweet today that popped up on my home screen. Didn't know I had this enabled. At the bottom of the Twitter notification settings is the home scrren toggle. Since disabling this, battery life seems better. Considering there is no setting for frequency of checking for tweets, it appears the phone is continually connecting to wifi to check for new tweets.
tmksnyder comments (notifications, corrupt data in iCloud):
For me, I found my iphone on wifi mysteriously connecting to my mac. I eventually narrowed it down to the Apple Move Trailers app which keeps a file in iCloud. The phone was trying to sync the file with the mac in the background even when the Movie Trailers app was closed (hitting the red x). Based on my macosx logs the iCloud process that was trying to sync was working directly between the phone and the mac without using itunes by connecting to an https address hosted on the phone. It was connecting every 3 minutes and failing (while phone was awake or awake during during a notification). I also found that iCloud control panel on OSX would error if I tried to delete the file. I fixed it by removing the App and doing a hard reset which stopped the sync. I probably could have turned off iCloud document sync in the phone but didn't think of that. My battery life has greatly improved while at home on wifi.    I am now at 28 hrs standby, 2 hrs 20 minutes of usage, and 68% battery. It was ok before where I could get 20-30 hrs standby and 6 -8 hrs usage. My usage today was phone calls, 3g surfing, and music via bluetooth in the car.
I also found even with Itunes iMatch, if I mass updated tages, art work etc, it would hit the phone on wifi even in standby. I was amazed.   Granted if I am not doing updates, Match won't hot the phone so this was a once in awhile event. I could drop my percentage by 5-10% in a matter of minutes when doing updates.   I think a lot of our problems are background processes, associated with iCloud, notification, and apps. More features means more battery.   I think the key thing is to keep track of what has recently been added or changed if battery life gets worse all of a sudden.   It may be an app that was recently installed and if possible you may want to completely remove it and not just quit it.
With twitter, i think it uses push notifications so it doesn't need to be running and actively poll on the phone. For instance , if i quit the mail app, i still will get mail notifications and can swipe the message and load mail. Apple Push Notifications servics maintain the connection to the phone and there are likely pings or connection checks that occur for the service on an os level not an app level. This minimizes the load so there arent a bunch of apps all runing and constantly checking. The notification service , if it is contacted from twitter or another service with data, will check the settings you have registered to the with the apple push service and send the notification to your phone. No matter what, there is a drain with notifications. M hunch is once one application is configured to receive notifications, connection checking occurs betwen the push service and the phone so it knows where it is on the network. If it is implemented correctly, these checks arent frequent if you are still and more frequent as you move. The other drain is for when the noification hits and is processsed. If i get 9 emails over night, my screen just popped up for 20 seconds or so to process each message using battery. I would even think that just go from low power to turning n the screen uses more juice than if the device was already on and i get the message. On nights I get no notifications, I see a 3 or 4 percent drop. On nights with a number of notifications, i have seen up to a 10 percent drop. Besides notifications, wifi sync and icloud will poll on the local network and use up battery if the host computer is on and running itunes or trying to sync a data file that is corrupt (which i had with the apple movie trailers app causing my phone to drain). For me turning off wifi sync and remving a corrupt file in icloud solved my battery issues and I get over 24 hrs of standby with 6 to 9 hrs of use and this is with all the normal location services and push serivices turned on.
See http://developer.apple.com/library/mac/ipad/#documentation/NetworkingInternet/Co nceptual/RemoteNotificationsPG/ApplePushService/ApplePushService.html for more info. I think it has a good overview of how the notifications work.

Well seems like that rumor of iOS 5.0.1 is finally gone the way of the dogs since developers got a beta of 5.1. So as stated earlier in the master discussion-> I suspect if you are filling up this thread with false post or creating a master set of links to various post that are unreliable you are wasting your time. Press is not going to touch the story due to poor or inaccurate sources which may be links from the master thread. This can include inaccurate information, combination of conflicting post or postings from users which may not own the device. Reputable press organizations have policies that require discloser and strict rules about what is a reliable source for a story. It is clear that many of the post in the master thread, which are links presented here are questionable.
Sorry to say that postings taken without any analysis of their totality have been propagated via various sites, for example sites such as http://www.2012federalbudget(dot)com. (Do not visit but I suspect that this is not the 2012 federal-budget site you would expect based on analysis of the records. There are plenty of sites like http://www.2012federalbudget(dot)com propagating questionable post in these threads.) One site for example in the discussion thread used a self signed certificate, the site had a log in to allow users to enter their OpenID. Seems many of these sites are pop and drop drupel configurations.
So remember this is how the really bad rumor of iOS 5.0.2 got started, the 5.1 memory leak issue, iCloud Issues, call quality, address book, etc.
Some of the postings have been very comical, I think the latest now is a dropbox issue. Seems that the length of the previous thread has resulted in various app engines of some proxy servers/tools reaching their limits.
So I would make sure to know the source of any information you link to. Make sure you avoid entering any information to outside links such as OpenID or Apple ID, these are big prize items for anyone with malicious intent. If you have issues and are a valid user contact APPLE CARE. (Note link is using McAfee Secure Short URL Service, and is https.)
http://mcaf.ee/ricdt
The original solution still represents a high level of success for users having any battery issues.
Install 5.0.1 on your iPhone 4s. Some users posting they are still using older versions, bad fake serial numbers, etc.
Make sure your device can run iOS 5.0.1 and is not altered.
Make sure you use a new Sim, not some cut down version which many users admit to doing. (Again, worth confirming what people are posting.)
Reset the device doing a hard reset and software reset.
Let battery drain and then charge for the full cycle, which is 24 hours.
I think you will find you will get the battery usage that APPLE has stated for the device.
Best of luck, stay safe and thanks

IPhone 4 battery draining issues

I've had my iPhone 4 for only 3 months, it's currently running on 5.1.1 and today for some reason it's battery life is significanetly shorter than it was yesterday, it's draining rate for usage is insanley high with 1% gone every minute i use it and i was able to fix the standby battery draining issue but I don't know how to fix the usage issue. I've done things like reset the setting and am currently restoring it but i doubt it will work, anny suggestions?

My own Battery Drain Issues on iPhone 5

Hello guys, I've just created an account here to share my many issues with iPhone 5.
Well, this wasn't my Apple's 1st product, as I've had Ipod touch 2g and 3g, as well as an iPhone 3g. But it's my first time experiencing crazy battery issues with an Apple product, wich is really sad and disappoint, since this is the MOST expensive cell phone in my country (Brazil).
It all started about a week after I bought my iPhone 5. One morning I was on the bus, going to work, and my iPhone had about 99% battery remaining. 1h20 later, when I arrived at work, I had about 80% battery, so I panicked.
Suddenly I realized I was a victim of the common i5 battery drain. I was loosing 1% battery each 3~5 minutes IN STAND BY. And my settings are the same as they've ever been: wi-fi off, 3G off, 4G off (since it's not available in Brazil), brightness on minimum, no weak cell phone coverage etc. So, I shouldn't be experiencing this at all.
After reading lots of threads around the web, I realized that the ONLY solution to this would RESET AND START YOUR IPHONE AS A NEW ONE. No backups, no deleting apps and data. Sometimes removing email accounts would work, but as I didn't use this stuff, restarting my phone seemed to be the solution.
So I did it and, apparently, my problems were solved. My phone has worked perfectly for 2+ months. And then I let it fully discharge - but it's was not the first time it' happened. After I recharged for 4h, I started loosing battery really fast again, so the battery drain have came back. It was so frustrating.
Then I sent my iphone to an authorized reseller and they manage to give me a new replacement phone. They've checked my old i5 and detected a battery issue. My charger and cable were also tested but they were ok.
Well, after the very first charge on my new phone - and I've set it up as a new phone - the battery drain started again. I couldn't believe it.
So now I'm waiting for my 3rd iphone 5 in 3 months...
PS: My original iPhone 5 was bought in the USA, and the replacement one came from Brazil. Both were running iOS 6.1.4 when the issues started.
After all that, here are my conclusions:
1) In normal conditions, with wi-fi, 3G and LTE off, you should expect your iPhone 5 to waste 1% of battery every 1h30~2h15 on STANDBY. This is based on my best iphone performance and on Apple's information: iPhone 5 should have 225h of battery time (in standby) at it's best. Since 100% = 225h, every 2h15min you should expect to "waste" 1% of battery, on standby.
Sometimes, overnight, your phone might have an even better battery life: my friend only lost 1% for about 8h/9h overnight. But this is just not common. Expect to loose about 2%~3% every night with all apps closed and no wifi/3G/LTE.
2) If you detect a battery drain, GO TO AN APPLE STORE/RESELLER RIGHT THE WAY. Don't even bother trying a reset, as I did, because it might solve the problem for a while, but it CAN come back. Go to the apple store and ask for a diagnostic of your phone and battery. It will save you a lot of time.
3) There are MANY causes to battery drains. The most common ones seem to be: 1- Push notifications/email related stuff -> Reset email, internet and settings. 2- Facebook app -> reinstall app. 3- Defective battery - go to apple store/genius and ask for a replacement phone.
4) If an iPhone comes from factory with battery issues, expect AT LEAST ONE other issue. My original phone's touch screen was unresponsive when charging on PC and connect to iTunes and my replacement phone's microphone was not working properly. So expect other defective parts
5) With my experience, I've realized I might have discovered A NEW CAUSE TO BATTERY DRAIN: A DEFECTIVE NANO-SIM CARD. Why? Well, because it's the only thing that I have used on both my iPhones (original and replacement ones). And it's the only thing thats has never been tested (both my charger and cable were tested on apple's reseller and were ok). And in my replacement phone, after I removed the SIM, I started loosing 1% battery every 1h20, when on stand by and with no wi-fi, 3G or LTE. So, if you have a battery issue CONSIDER THE SIM CARD TO BE THE PROBLEM.
Also, when my replacement phone was near any amplifier/pc speaker, it would make the amp make that "call or text incoming" sound. (to understand this, put your phone near an amplifier/speaker and ask for someone to call you). This makes me believe that the SIM card was, somehow, defective and making my phone receiving data (and I mean only telephone data, like related to calls and sms) when it shouldn't.
That's all my friends. If anyone has ever experienced this crazy issues, please try to help me. I'm getting a new sim card, iOS7 and my 3rd replacement phone and let's see if it works as it should.
Sorry for the MANY mistakes, my English is not good =\.
Cheers from Brazil!

Hi Folks,
iPhone & iPad2 battery drain issue SOLVED!!!!!
I had a serious battery drain problem on THREE devices using different iOS .... it was a simple fix and had certain characteristics that you may be able to relate to ......
Devices;     16GB iPhone 4 with IOS6
                  16GB iPhone 4S with iOS7.06
                  32G iPad2 with iOS7.04
On or about Feb. 28th all three devices started to drain the battery like crazy losing about 20%/hour on the iPhones and 10%/hour on the iPad2 .... After messing around with settings, browsing forums and looking at what was common between the three devices I concluded the problem was with a single Microsoft Outlook/Live/Hotmail email account in the iOS native mail app .... I deleted the email account on all three devices (along with other unrelated Microsoft accounts on each device) and did a hard reboot (hold HOME and top LOCK button simultaniously for about 10 seconds until the apple logo appeared).
I then re-created the common Microsoft Outlook/Live/Hotmail account on all three devices in the iOS native mail app ...... SUCCESS! Now all three devices are behaving normaly with respect to battery drain ......

iPAD 3 battery charging issues. Read most of the discussions. My question is: If I take my iPAD to Apple Genius bar - what's the test they do to qualify for a replacement (do they place it on a charge and see the charge for Y% for X minutes or do they have other methods)

We're iPad users like you, so don't know.
The quickest way (and really the only way) to charge your iPad is with the included 10W USB Power Adapter. iPad will also charge, although more slowly, when attached to a computer with a high-power USB port (many recent Mac computers) or with an iPhone Power Adapter (5W). When attached to a computer via a standard USB port (most PCs or older Mac computers) iPad will charge very slowly (but iPad indicates not charging). Make sure your computer is on while charging iPad via USB. If iPad is connected to a computer that’s turned off or is in sleep or standby mode, the iPad battery will continue to drain.
Apple recommends that once a month you let the iPad fully discharge & then recharge to 100%.
How to Calibrate Your Mac, iPhone, or iPad Battery

At this link http://www.tomshardware.com/reviews/galaxy-tab-android-tablet,3014-11.html , tests show that the iPad 2 battery (25 watt-hours) will charge to 90% in 3 hours 1 minute. It will charge to 100% in 4 hours 2 minutes. The new iPad has a larger capacity battery (42 watt-hours), so using the 10W charger will obviously take longer. If you are using your iPad while charging, it will take even longer. It's best to turn your new iPad OFF and charge over night.

Iphone 4 from sprint and battery drain issues

how many people out there bought a new iphone 4 from sprint and having the rapid battery drain issues? there is a big thread on the 4s but not as much on the 4 and im trying to decide if its best to just exchange it or try more fixes.

I have the same issue. I am with sprint. The battery goes down in 6 hours, mostly in standby and some emails. I can actualy see the battery meter going down every 30 sec when reading my mails. iCloud is disabled as also push notification. The phone gets also hot. This issue is completely stupid and remember, I had iPhones for the last 3 years. My last one was the 4. It is first time I have such a problem. My friends that have the 4S with AT&T do not have that problem. As a mater of fact, I compared today and mine goes down 50% faster. I will have to return it and switch to another provider.

Possible solution to iOS 7.0.3 battery drain issue (iPhone 5).

Not a question as such, but for anyone who's having battery drain issues on iOS 7.0.3 and doesn't want to attempt upgrade to iOS 7.0.4 revision yet...
I was having some problems with battery drain with my iPhone 5 since updating to 7.0.3. The device is only about 5 weeks old so I was quite annoyed that I had issues with it.
This morning after a full charge I did a hard reset. Now the problem seems to have gone. I've had the phone on for several hours (about 4.5hrs) and it's only just dropped to 99% moments ago. This is a massive improvement (on even the battery life of the device when I got it, and it had 6.1.3 factory installed).
I hope that this helps anyone who doesn't want to risk 7.0.4 until it's had a chance to cool off and for people to identify/resolve any issues (as I am waiting too).

The update isn't the problem. It was a problem with your update process. millions of others have updated without any issue at all.
Also resetting has been discussed many times in the never ending battery draining threads.

Are battery drain issues fixed in 6.1.3?

I realize it only came out a few hours ago, but can anyone confirm if the Exchange bug that wasn't completely fixed in 6.1.2, and/or the iCloud Document Sync over cellular were fixed in 6.1.3?
Thanks!

Good evening all,
I too am an Apple Developer and have been messing with these devices for a while. I can attest that 6.0.1 was the most stable and efficient iOS v6 I used. I have a 4S and a 5, both ran 6.0.1 until the "exchange bug" was fixed. I am sorry I upgraded my 5, because I see significant battery drain issues with or without Exchange configured. I have restored from DFU, Reset All settings, turned on and off all settings, etc (every trick on the forums) I test and tune for a living and clients complain to me and ask for a fix, so I do the best I can. My 4S with the SAME configuration as my 5, lasts FOREVER! When a phone works perfect, and one "upgrades" software and sees problems, 100% is related to the software, not hardware. Unless the software is not compatible with the hardware, then I would make the safe bet and say the software is the culprit, def an Apple realted issue IMO.
The reason for Apple to change the software on devices is because it changes how the hardware functions. Without software, our hardware would be nothing more than paper weights. Working with software for years I know its hard to get it perfect for millions of users. Apple has their work cut out for them. I don't expect perfection, but it would be nice to build on a good foundation. I thought they finally turned the corner with 6.0.1 but 6.1.2 is a painful reality for people whom truly rely on their mobile devices. Have faith, because 6.1.3 from a restore from a "new phone" has been working smoother for myself..so far.

Battery life issues on iphone 5 with ios 6.1.4

I had upgraded the OS on my iphone 5 to iOS 6.1.4 and now I am facing extraordinary battery drain. I left my phone at 35% battery life while going to sleep and when i wake up, after 8 hours, it has gone down to 8% and less. This was not the case before with the earlier version of iOS or my iphone 3gs. I have tried some tips and suggestions but I dont think those are really helping. Could someone please help me out as to what should be done in this case.
Hope Apple is listening and intend to do something. My phone is brand new and not even a month old.

No i do not have LTE network access at home.
My cellular reception is quite good at home as well as work.
Yes i am using an exchange account, gmail.
This is what i have tried..
turning off SIRI, auto adjust brightness, push messages, notifications, blah blah blah...
Seeems like deleting and adding the mail account once again helped, as i am experiencing a better battery life today. I had read about this somewhere but weired that this could be a solution to a battery drain issue.
But still I am planning to take the phone to a store to get its battery checked.

Iphone 4s IOS 7.0.4 update battery drain issues

I hope this gets to apple in regards to the issue of the battery drain. I have been following several discussions for the past couple of weeks and everyone seems to have some type of idea on what the problem is. I'm not a service tech or gadget know all, but I have been performing several "Nonscientific" test to see what is draining my battery.
I have a 4s that has always had good battery life. It seemed to run consistent to what was detailed in the product specs. I would only need to charge it every other day on limited use or the next day with heavy use. After updating to the latest update (IOS 7.0.4), the battery would drain in less than a day on limited use which is a couple of text, couple of email checks, 3 to 4 phone calls at less than 10 minutes each - no internet searches or game play.
So, after reading everyones suggestions in the forums and trying them, the battery still drained just as fast, if not faster. I read a post somewhere regarding “Bluetooth” constantly searching. So, I saw mine was doing the same. Someone replied to that person that it should not be the issue, as it does not use much power to run its task. (I found they were wrong)
Here is my nonscientific test, but a good one. (for the record I had nothing on in the notification center, Do not disturb off, only thing on in Privacy - location services was google maps, Siri, Yelp, and Find my phone; iCcloud was off; background app refreash was off; email fetch data was off; everything else was off)
Day 1 - I fully charged my phone several hours, I unplugged it at night before going to bed, did a hard reset to make sure every app was off, and only opened the settings app and made sure the Bluetooth was onand searching. I checked my phone 6 hours later and saw the battery drained from 100% to 56% with no usage other than just being on and in sleep mode. That would mean it drained at 7.3333 % an hour. Some would say that acceptable. - Its not when there is no usage. The battery would die in 13 hours with no usage.
Day 2 - I repeated the test (as above), but turned off the bluetooth. I checked my phone 6 hours later and saw the battery did not drain at all. I started with a 100% and battery was still at a 100% with no usage other than just being on and in sleep mode. I opened a couple of apps and closed them to prevent them from running in the back ground and noticed I lost about 2% of charge after usinging it checking an app or 2. I put it back to sleep mode and checked it again in an hour and saw it only drained 3% down to 97%. Very acceptible.
Day 3 - I repeated the test, but during regular day hours with limited use of the phone (with bluetooth off). I was back to getting close to a normal battery drain I was experiencing prior to the update. I know that IOS 7.0.4 uses a little more battery power to run as it has different features and abilities, so the battery drain was not like it was before, but a lot better.
So, my experiment concluded to me that the new update is causing the bluetooth searching to run in the back ground continuously and causing the battery to drain unacceptably fast on my phone. This is a program issue that can be fixed by Apple. I find it unacceptable to have to control my bluetooth manually, as I never had to do it before and I shouldn't have to do it now. I hope Apple will fix it soon. I‘ve been a apple product person for years, and enjoy the products, but lately they have been not been satisfactory in the phone business. I have been playing with a samsung galaxy thats looking very promising, if apple doesn’t fix the issue everyone is having, they will loose business to competitors.
Please fix the issue!

Hi Folks,
iPhone & iPad2 battery drain issue SOLVED!!!!!
I had a serious battery drain problem on THREE devices using different iOS .... it was a simple fix and had certain characteristics that you may be able to relate to ......
Devices;     16GB iPhone 4 with IOS6
                  16GB iPhone 4S with iOS7.06
                  32G iPad2 with iOS7.04
On or about Feb. 28th all three devices started to drain the battery like crazy losing about 20%/hour on the iPhones and 10%/hour on the iPad2 .... After messing around with settings, browsing forums and looking at what was common between the three devices I concluded the problem was with a single Microsoft Outlook/Live/Hotmail email account in the iOS native mail app .... I deleted the email account on all three devices (along with other unrelated Microsoft accounts on each device) and did a hard reboot (hold HOME and top LOCK button simultaniously for about 10 seconds until the apple logo appeared).
I then re-created the common Microsoft Outlook/Live/Hotmail account on all three devices in the iOS native mail app ...... SUCCESS! Now all three devices are behaving normaly with respect to battery drain ......
Hopefully this will be useful to others in this thread ..........

Odd battery life issues after improvement w/ 5.1

I have an iPhone 4 GSM (AT&T) that was experiencing significant battery life issues with the previous version of iOS (5.0.1?).
After updating to iOS 5.1, the battery life improved signifcantly - I could now get comfortably through a day with 50% remaining at bedtime versus 20%.
In the last couple weeks the battery life started getting worse and worse, to the point where I could barely get home from work and it would be 10-20%. I started to pare back the settings like Location Services, notifications, frequency of email checking, etc. with no improvement. I noticed the phone seemed to be running warmer than usual, so I thought there may be some software issue causing an infinite loop...
I Reset Network Settings as I've heard that can help - no difference. Then I wiped the iPhone and restored from backup - no difference. Finally I wiped the iPhone and set up as New, only installing a few apps and being very conservative with push, GPS settings etc. I am still down to 20% by 5 pm, and this is with light use. Wifi is on all the time, which is what I primarily use, but it never caused this much drain.
It's also quite variable - the other day I made it home with about 70% battery life, but then it dropped 25% in 30 minutes with only light usage (email/web).
Is the battery itself going bad, and/or is there any way I can test it? I got this phone as a warranty replacement (probably a refurb) in July 2011 so I don't think the battery is that old.

Just an update. I totally wiped my iPhone 4, and turned everything off including keeping it in Airplane Mode and it seemed to help a little - it was over 80% at noon without any use. Of course, the phone is useless like this. As soon as I turned wifi on at work (still left the cellular radio off) it started dropping fast.
It must be the battery going bad, but I was just wondering if there are any other suggestions. I don't want to pay to get a new battery installed if I don't have to, since by this fall I will be eligible to upgrade to iPhone 5 if it comes out.

How can I fix the battery drain issue on my iPhone 5s? it started when an updated to iOS 8.2 and upgrading to iOS 8.3 still did not fix it.

Search this forum. Your issue has already been addressed ad nauseum.

Could Exchange be a cause of the battery drain issue with 3.1.2

I've never had a significant battery drain issue until I upgraded to 3.1.2. This started four days ago, when I've been relying on 3G more rather than WiFi since I've been out of town. I just changed my work e-mail Exchange from push to fetch every 15 minutes, and it seems to have improved some of the battery drain problems. I haven't done the experiment yet of switching back to push. Any other similar experiences out there?

There were reports some time ago of incorrectly configured Exchange servers sending out too many push messages, thus draining the battery faster than normal.

IOS 7.0.6 sound, powering down, and battery drain issues

Since updating my 4s to iOS 7.0.6 I'm having trouble with my sound. While I'm trying to watch YouTube videos or Netflix, one minute it will be ok then the next it will just go silent. It's almost like it thinks there are headphones in the jack but there aren't and when it does this I can't even turn the volume up or down. I've tried everything I can think of... Hard reset, killing the apps, searched in the settings, ect. I don't know what to do and it starting to really irritate the living **** out of me because it never did this before the 7.0.6 update. Also since the update I installed I've been having serious issues with my battery draining at a very rapid rate and this too I've killed all the apps running in the background, lowered the brightness, and all other battery stuff I can think of. AND on top of all of that since this new ******** update I can't even turn my phone off! I slide it to power off and it acts like its going to shut down like normally, the screen goes black and all looks good and then wouldn't you know it the apple logo pops back up about 3 seconds later with out even touching the phone.......... SOMEONE PLEASE HELP ME!!!!

I have an an iPad air and I updated it to IOS 7.0.6
- no battery draining issues
- no overheating
IOS 7.0.6 does not brick any device.

New iPhone 6 Plus battery standby time is 12 hrs

I bought my iPhone 6 Plus directly from Verizon website about a month ago. Since than, I am having constant battery problems and it is practically burning during a charging process. ( I am using the charger that came with the phone). I checked the battery standby time today and it is less than 10 hrs when the battey is at 76%. (only used for 2 hrs and 46 min after last full charge).
Iphone 6 plus suppose to have good battery time (10days standby time) while my brand new phone has standby time of 12 hrs. What should I do?

Maybe you should contact Apple Support and talk to them. They can check the battery online.
You can also visit this page to do that: iPhone - Contact Support - Apple Support
Click on Apple Support, then on ->Battery, Power &Charging ->Battery questions and troubleshooting, and follow the instructions.
