Another thread: Poor iphone5 battery life.

Hi,
Wondered if anyone had any similar experience and if they could fix it without a replacement phone:
10 days old iphone5 16G.
Initial Battery life with very light use: 22h.
Reconfigured: Turned pretty much everything off apart from 15min fetch email: 36h
Reset: No improvement.
Restore as new: 48h with ony 2x 30 secs calls so mainly standby only.
Any suggestions guys?
Thanks
John

Update:
Post Restore as new: Did NOT restore from backup. Then did deep discharge. Now battery life is in excess of 54h with full pretty heavy use. (although crazy location and icloud stuff turned off).
Really happy. Great practical real-world phone. I guess it is a software issue post 6.0.2 update.
Just goes to show; listen to the support guys and do what they say *exactly*. Dont skip any steps or add anything to what they say and all will be well. I was skeptical but now converted. Respect.
Good luck to anyone with this issue.
Cheers
John

Poor 4S battery life while using apps

Most of the posts I've been following about cruddy iOS5 battery life seem to revolve around when the phone is in standby. I seem to have that mostly addressed on my phone. So my big complaint is how poor the battery life is while I'm actually using the phone. I'm coming from the 4, whose battery life wasn't really stellar, but this is by far worse.
I know they dropped the estimated battery life on WiFi from 10 hours to 9, but what I'm experiencing is worse than that. I played 10 minutes of a non-intensive game yesterday (one that wouldn't have a large battery impact on my 4), and in those 10 minutes, the battery life dropped from 75% to 69%.
As of right now (12:31), my battery life is at 22%, down from 76% at 6:30 this morning. With my 4, I would have been in the mid 50s, and I've done nothing differently than I would have a week ago. Checked my mail, read a couple of static pages in Safari, messed with the Settings a little, checked my calendar and reminders a couple of times--nothing intesive. No games, no map. I did browse the App Store for about five minutes, but... This is all standard usage sorta stuff that never would have drained half the battery life with my 4. My "usage" even shows that the phone has been inactivate for 3 out of those 6 hours.
Any suggestions on this? My standby life, while not fantastic, isn't horrific, so I think I've effectively tweaked a lot of the tweakable things (like location stuff, diagnostics, etc). But is there something I could be missing? I have the screen on auto-brightness with the slider set to just below the "gh" in "Brightness." That's where I kept it on my 4, too.
I thought I read the new battery was actually better, but this is definitely not an improvement

I have the same problem! Mine does last for about 3 - 4 hours, but that is about it! Any suggestions?

Iphone5 battery life

How long should the battery last when fully charged, with location services turned OFF? I'm going on 13 hrs while using WIFI and different apps throughout the day, I "kill" apps when not in use. Is there something I'm missing or is this it as far as battery life goes?

Tons and Tons of threads on this issue.
https://discussions.apple.com/message/19790185?ac_cid=tw123456#19790185
But today I have been testing my battery..
my stats are 22 hours 27 min standy, usage 7 hours 6 min, and at 5% battery left.
To me that is pretty good, but Apple should improve with an IOS upgrade.

Poor ipod battery life

My ipod touch 5th gen gets terrible battery life, even with brightness all the way down, and the do not disturb and airplane mode and wifi on, please help

How long does a full charge do after charging for four hours?
What is the iuPoid donig during that time?
Try:
- Reset the iOS device. Nothing will be lost
Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Reset all settings
Go to Settings > General > Reset and tap Reset All Settings.
All your preferences and settings are reset. Information (such as contacts and calendars) and media (such as songs and videos) aren’t affected.
- Restore from backup. See:
iOS: How to back up
- Restore to factory settings/new iOS device.
If still problem, make an appointment at the Genius Bar of an Apple store since it appears you have a hardware problem.

Poor MacBook Battery Life

Hi,
I've owned my 13" Retina display for about a month. The most usage I get out of a full charge is 3 hours (keyboard lights off, screen dimmed a bit). All I'm using it for is reading articles and writing text/emails. No Photoshop or other big problems.
Meanwhile my friend can run his from 9am to 4pm daily without recharging.
This is really disappointing. The first powerbook I purchased I had to replace because it kept freezing. Now this.
Is there a solution?
Cheers.

futureperfect,
you’re still in your 90-day gratis Apple telephone support period — make use of it. Call Apple, get their recommendations (even if it’s “your battery is defective, bring back your MacBook Pro for a replacement unit”), try them out, and report back in your reply what worked for you, so that others can benefit from your experience.

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!

4. Fully discharge battery (till it shuts off with the spinning wheel)
5. Fully recharge battery (overnight if possible)
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

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

Macbook Air mid-2012 battery life issues -- a possible culprit ?

Hi all,
I've posted and followed a thread regarding diminished battery life for the mid-2012 MBA, when Mountain Lion was released. I never could fix the problem, was contacted by Apple but that didn't solve anything either.
The troubles I was (and still am) having with my MBA were :
Battery life reduced by at least 33% when I upgraded to Mountain Lion from Lion, following a firmware update.
No change when I clean installed ML.
No change when I upgraded, and then clean installed Mavericks.
My battery, after 13 months of use, had its capacity reduced to 70-80%, and has now been stable for one year at 70-80% capacity. It now lasts approximately 3 to 4 hours, and has never lasted longer than 5 hours since I upgraded to ML, which was a few weeks after the laptop was purchased...
I've tried everything that was posted on the forums, SMC resets, etc. Now to the (maybe) interesting stuff.
I stumbled today on something interesting. I was researching my issue to see if people with the same laptop, that followed the same firmware upgrade path than I did had similar issues. Long story short, a forum post led me to something interesting, located at /System/Library/Extensions/IOPlatformPluginFamily.kext/Contents/Plugins/ACPI_SM C_PlatformPlugin.kext/Contents/Resources
DISCLAIMER Whatever you do, do not try to remove / move anything in this folder.
What is interesting is that my Macbook Air has the following identifier : MacBookAir5,2. However, in the above-mentioned folder, there is no MacBookAir5_2.plist, it stops at 4_2.plist and then goes on to MBP models. Now, the question that I have is could the fact that this plist is missing be related to my battery issues ? In the sense that without this file, the kernel does not know how to properly manage the power, read the battery status / thermal sensors ?
I would really love to fix this 2-year old issue that has been plaguing my laptop ever since I purchased it.
Cheers,
Hadrien

I leave my LithiumIon battery plugged in when near an outlet. But I use it on battery down to 40% at least once a month.

Tips to Extend BlackBerry Battery Life

Just scanning this board, I noticed a few inquiries about BlackBerry battery life. Namely, a thread on Pearl battery life and Curve power issues.
So I thought I'd post a link to five tips to extend your BlackBerry battery life.
There are some basics like shutting off your device at night or when you know you won't need it, and some more advanced suggestions like optimizing all your phone and message notifications and your third-party application alerts.
Check it out.

Hey, hope everyone can read this,... For some reason I seem to be unable to post a normal response.
One thing that is apparent with the battery of the 9700 is that the battery actually gets extremely warm on occasions when charging. Originally I thought that it was just when I charged via USB cable but I have since discovered that it is random (could be either wall charging or USB charging). When the battery gets too hot it doesn't retain the same sort of battery as otherwise (i.e. it lasts anywhere less than 7 hours before needing a charge). Other times it seems to last 3-4 days using multiple applications.
Additionally, I was all old fashioned when I got my 9700 (beginning of 2010) and so I decided to charge my battery to full. This hasn't made any difference to me... Occasionally I have good battery life and something I have really really really really really bad battery life (the one time I charged my battery full before I went to sleep, I was woken up with my phone turning off due to lack of battery and nothing was running in the background... This was due to the heat generated from the charging). Nothing to do with the initial charge... That was, as someone said, a 1999 retarded and stupid phenomenon. We have subsequently had advances in technology (yes, believe it or not but a lot changes in 11 years) and as such battery 'memory' no longer exists in the same sense as it did before.
Bottom line, if you didn't discharge your battery completely and then completely recharge it again it won't make a difference. It would have many many many many years ago and some people will still say it is the case. Listen to them if you would like to be sure but the only difference is the time it will take before you can use your device.

After installing lion, battery life cut by 75% and browser speed slowed to a crawl

My Mac Book Pro was working perfectly fine until I installed Lion. Now my battery life has been cut but a least 75% (only lasts about 45 minutes on a full charge) and it has also affected the speed of my browser.
Can anyone help?

There is a 190 page thread discussing the battery life and health issues assocaited with ML that you will find in this forum located here: https://discussions.apple.com/thread/4135250?start=0&tstart=0 . Some people have had some success in installing the ML 10.8.2 combo pack over their 10.8.2 instance. Some have had success in performing a clean install. Others still have problem, and others have moved back to Lion or SL. In your posting, are you saying you've installed Lion or Mountain Lion? I'm assuming that latter. I've recently reverted back to Lion until I have more confidence that Apple has tackled the issue.

After 4.2.1 Dropped/Choppy calls and poor signal / Gets hot / Battery Life is bad when talking

What is this APPLE? I can see the Iphone 3G is old and no more support but atleast make a working OS and then go out on a high note. Instead of leaving us hanging with a broken phone. Not just me , scores of others have these very same symptoms. Also I wish there was a way to go back to an older OS , one that worked %100 for my phone.
Dropped/Choppy calls
Get REAL warm
Batterylife is crap only when talking
Never had these problems before 4.2.1 , it's like night and day. I was hooked on the Iphone since I bought this 3G brand new and its ease of use but Ill tell you one thing....
Im not under contract right now with anyone
I WILL NOT be buying a phone/contract with APPLE as long as 4.2.1 is left in our "lap".
I WILL be buying another smartphone if this is what we are left with. I was going to treat myself and buy the 5G with a contract to make it cheaper but as of now
Im feeling "used" by APPLE and not going to take it.
I know some might come here and post ..
"Me and others aren't effected by 4.2.1 , must be your phone"
BS! It was night and day when I downloaded/installed 4.2.1. This is NOT my Phone and IS the firmware. And my friend that is a phone nut said he didn't download 4.2.1 because of all the problems he was hearing about it, I should have done research. He said the biggest hit was the 3G and he can't belive I installed it.
APPLE DO YOUR JOB AND FIX THIS. MAKE 4.2.2 ATLEAST AND FIX THESE PROBLEMS!! IF NOT THEN WE MUST PART WAYS.

Cool
Did the new device and didn't do a restore from backup. Grabbed all my contacts from windows contacts saved list. So only thing the same on the phone was the same 4.2.1 that stays in there. Still bad signal and battery life, although the battery problem might be the age of the battery since its the same battery that came with the 3G.
I did the Field Test mode program
http://socialtimes.com/find-your-iphones-signal-strength-using-the-hidden-field- test-mode_b4690
- Open the iPhone’s dialer keypad
- Enter *3001#12345#*
- Press the Call button
-80 to -70 dBm: Reasonably strong signal
-107 to -90 dBm: Weak signal
-113 dBM: No serviceable signal
In my house im getting any were from -100dBm to -117dBm ( 1 to 2 bars with 3G)
Outside Im getting -85dBm and up. (2 to 4 bars with 3G)
I have to do more testing to get solid numbers though. I got almost full bars all the time if I switched to EDGE.
(4 to 5 all the time with EDGE). That makes me think that with the problem in 3G , it's the OS. Since ALOT of people saying that there 3G drops or is bad since 4.2.1.
Now I looked around and I playied with all my settings to insure that my battery should not drain thru improper settings. So I think given this is the original battery , it might be a good time to try and install a new one from here for $17.
http://www.iphonebatteryrepair.com/iPhone-3G-Battery-p/bat-1001.htm
Iv'e opened Iphones before (fixed my friends 3G) after he dropped his and the vibrate/silent button's screw came loose and he could not change it off silent mode and replaced a battery in my other friends 3Gs. SO i feel comfortable in there.
I dont know if the bad battery could be reducing my signal.Ill try the battery cause it's only $17 (Cheap investment) and because my battery life under a load drains it fast. Again I don't know if it's the OS or the age of it.
I was thinking maybe a poor contact/condition of my SIM card could be another possibility. I wonder if and how much a new SIM card from a AT&T provider is. I heard people saying you can get a new one but Ill have to ask my local AT&T dealer.
Although this seemed so odd how it all happened the same night till now RIGHT after the 4.2.1 OS install and all the others people saying the same symptoms.
Ill keep working with it and give you (and others users here) updates in my progress for the people who are in the same "boat" as me.
By the way I haven't tried to make Itunes re download the OS by deleting the file in the directory you gave me above. Ill try that as soon as I post this message.
Also Iv'e noticed that theres a way to download a older version of Firmware OS and put it in a certain directory and use the DFU mode (Deep Firmware Upgrade) on the Iphone to force the Iphone to re install the current version or an older version ( whatever version you download) of firmware. Now Im very worried that this might mess my Iphone up to were it wont even work so I really dont want to try this right now or until I exhaust all my other options. I have to do more research of this method.
Sorry for the long post but I think I kept it faily organized for a easy read, I hope.
                            Thank You Ingo !!

Nokia 206 poor battery life

I had the 206 coming to a week now. And I charged the battery on Fri night full and by Sun evening it was saying battery low and I only used fb, text and whats app. Few mins worth of calls and no music.
Also the phone seems to turn off when using whats app or facebook sometimes.
This is annoying.
Also the E for the internet Edge is on all the time will this kill battery too ?
Dunno how people get 8 days of battery life seems impossible!!

I suggesting you turn off the Mobile Data when you are not using the Whatsapp and Surfing. Just go to Counter>Mobile Data>Select Off>The E on the top should disappear now and the battery get longer. If you want to use the data again Just Follow the steps again above and select On.
That is long process to turn it on and off!
The E doesnt disappear when I turn it off! This is strange!! The rectange around the E disappears but not the E itself.
It managed another 2 days and am recharging it right now.
It cant drain the battery for using whats app for about 10 messages come on get real folks!
The phone apparently can do what 25 hours it was said as talk time? Thats a lot more than whats app.
The internet is very slow and poor also, very disappointed with this tat!

Macbook Air Poor Battery Life

I have a mid-2012 Macbook air and I've noticed recently my battery life is horrible. I've read every single other thread about this issue but nothing really helped and even the most recent is from a couple of years ago. Obviously now it's 2015 and my macbook is running on Yosemite, so its not the battery issue that everyone seemed to have with Mavericks.
Just writing that small section I went from 73% to 68% and at the current 68% I only get an estimated 2 hours and 10 minutes remaining. I've also had only Safari running this whole time.
Option clicking the battery icon reveals that the condition is normal, as well as the power system report. It also has gone through only 441 cycles, no where near its 1000 cycle "limit" and its health is already down to 77%. While obviously the condition is normal and doesn't say I need to replace the battery I feel that I should, based off of everything else.

Have macbook air from mid 2012 - I installed Yosemite November 2014 and since then I'm having problem with my battery - it has been draining super fast - 4hrs battery life now compared to earlier 8hrs.
I reinstalled Yosemite, didn’t help and then made a clean reinstallation of Yosemite about 5 days ago and there is still the same drain issue.
Thank you in advance!

Poor battery life and WiFi connectivity on iPhone 5s

I have bought a new iPhone 5s 16GB running iOS 8.1.2 3 days ago. The device that I have got has a poor battery life and WiFi connectivity. I have tried lots of methods given on the internet like turned off the auto-brightness, reset the phone to default settings.
Then contacted the Apple Care for battery issue. They asked for the diagnostics to check the problem. They said its happening because of the crash of inbuilt app Springboard asked me to try "Set up as new iPhone". Even after doing all these, I am still getting battery not more than 4 hours.
This is not expected from Apple. Such an awful experience on my first iPhone buying.

Where exactly did you buy this new 5S?

Poor battery life and high temperatures on MacBook Pro Retina 15"

I'm having never-ending problems with poor battery life and high temperatures on a MacBook Pro Retina 15"
I took it in for service and they told me it needed a new logic board and replaced it. When I asked why they were vague about the reasons, they said "it just needed one, it failed some test". I now have the computer back and it runs the same way it always did. I bought this laptop because it was supposedly capable of high end video editing in 1080P (or so Apple's website claims) and also photo editing.
"The processor, graphics, all-flash architecture, memory, and display in the 15-inch MacBook Pro give you unprecedented mobile video editing capabilities. Super-responsive flash storage delivers up to nine streams of 1080p ProRes (HQ) content for multicam editing in Final Cut Pro X,3 while the latest quad-core processors on the 15-inch MacBook Pro decode multiple streams of video, and a powerful GPU renders millions of pixels onto the screen. With flash storage that offers up to four times the performance of a traditional hard drive,1 you can even edit four streams of uncompressed 8-bit 1080p HD video, right from the internal storage on your 15-inch MacBook Pro with Retina display.4"
However, when I'm just browsing the web and emailing it runs quite warm and battery life is quite poor. Sometimes doing those same activities I would say it gets so warm it's almost uncomfortable to have on your lap and the fans are running fast enough to become noticably noisy. I'm also driving only one screen at and a time and I heard that the MacBook Pro can supposedly do three screens.
If actually try to do something like video editing with final cut pro the laptop gets really hot, the fans are on full blast and battery life drops to only an hour or two. I think when I rendered just a 3 or 4 minute clip once I got less than hour of battery life. I will have to time again.
Anyway most people (including the sales guys) are telling me no way this is not normal. When I play with demos in the store browsing the web they are not getting warm or hot to the touch. My friend's 2013 MacBook Air is also NOT getting warm to the touch doing the same activities.
I installed iStat Pro so I could check the temperature and fan speeds. I'm seeing temperatures of 70+ on the GPU, 85+ on the GPU diode and 65+ on the CPU heatsink along with elvated fan speeds above 5K which becomes noticeably noisy. I understand that might be normal for the most processor intensive tasks but it really doesn't seem right for just light web browsing and e-mailing. (I also may have viber and skype open but that shouldn't matter). CPU usage is usually running between 2-10% as this is all happening to.
Furthermore, straight from the specs:
Intel HD Graphics 4000
NVIDIA GeForce GT 650M with 1GB of GDDR5 memory and automatic graphics switching
I am assume "GPU" and "GPU diode" are temp measurements on the discrenete NVIDIA video card, especially since MacBook Airs from the same and newer generatio do not have this reading. Since Apple Claims the graphics "automatically switches" it seems all the harder to believe the GPU is reaching 85+ when in theory it shouldn't even be activated. I mean, shouldn't the INtel HD Graphics 4000 be capable of simple web browsing and e-mailing? Especially with only one screen activated (be it it the internal or an external)?
What should I do here? When I asked the repair guys "OK well what is the normal operating temp range for the various sensors" they said "Sorry Apple doesn't provide that info".

Yes I have.
Just web browsing and basically doing nothing I'm hear a lot of aduible fans, I'm getting 85C+ on GPU diode, 65+ on cpu heatsink. I since installed anohter program that shows me not just the CPU heatsink but the cores and the cores are at 90C+.
Seems like a lot of heat for doing nothing. Not only that but I have these problems with no external monitor while on battery power too.
I don't know what to do. They already replaced the logic board. Others seem to get advertised battery life out of Apple products and not have products that get **** near hot enough to burn you while just web browsing or watching a movie let alone advertised tasks like Photoshop and Final Cut Pro.

I have had my iPhone 4s for a few months and the battery life was really good. Then around the same time I updated to ISO6 and I dropped it on the floor and since the battery life has been poor lasting only a few hours. Does anyone know why this is?

I don't know why the battery life has just become so poor. I can listen to 1 song and lose 1/2% battery life. I had all the settings the same as before updating to ISO6 and now it just goes. I did drop it around the same time but I have a stong case so I don't see how this should effect it. If anyone knows how to fix it would be a great help because I used to love iPod but I am very dissapointed.

Internal damage from fall or loose connector. Take it to
Apple to be checked.
