IPhone 3gs Battery life with 3.1 firmware

Any news regarding battery life with firmware 3.1???? I have lost at a minimum 25% after upgrading from 3.0.1 to 3.1. Have reset....the device alone and with iTunes....Need help...

I originally posted this in the wrong discussion...
Since upgrading to 3.1, it looks like the biggest battery drain is due to using PUSH with my Exchange email. I can turn off PUSH, use FETCH (even over 30 minute polling intervals) and battery life is close to 24 hours on a charge. Turning on PUSH, but not using it for email (other than my .Mac account (MobileMe), decreases the life by a couple of hours, still well beyond the normal 10 hour work day.
Turning PUSH on for 3 Exchange folders (Inbox and 2 sub folders) results in a drastic reduction in battery life. It can use over 50% charge while on standby... over a 3 hour period. I've managed this to an acceptable (8-12 hours, depending on phone calls) by limiting using Exchange rules to keep most important email to the Inbox and one sub-folder (I may eventually leave all important stuff to the Inbox) and move other stuff into different folders that I can still check on occasion.
Other PUSH activities, using apps like BeejiveIM, AP News, MLB.com, i.TV and even .Mac don't seem to affect the phones battery life too badly.
I'm wondering if Exchange w/PUSH is doing too much, besides listening for new mail and alerting on it. Could the process be simplified to only listen, alert, and mayby increment the count (not downloading headers or message bodies until one actually checks for messages... the iPhone still polls once you open a mail folder anyway).

Iphone 4s battery problem with ios 8.1

I actualized my iphone 4s with ios 8.1 and the battery dures 8-10 hours, meanwhile with ios 8.0 dured more than a day with the same use. I turn on the phone at 8:00am with full battery and at 6:00pm the battery has less than %10 charge. Could ios 8.1.1 fix this problem?

Thanks for the help. I've tried to do what the instructions of the blog says, but I can't see the battery ussage and standby information. I don't know why, before the instalation of ios 8.1. I saw this information... What can I do to see it again?

Iphone 4S battery drain with iOS 5.0.1

I am experiencing just about the same battery drain with the iOS update as I did before.
I was wondering how many of you had the battery drain problem, updates to iOS 5.0.1 and had that actually solve your battery problem.

I have IPhone 4 and I updated the IOS to version 5. After the update the battery lasts about a day. After the update to 5.0.1 the battery lasts a day and a half. It is an improvement, but not as I expected.
The next step is to disable configuration options like:
- downgrade from 3G network to 2G
- disable Data services
- disable automatic clock
- disable location services
- use the phone only as a phone and nothing else.
I will come back to tell how much the battery lasts.
PS: the IPhone 4 is new so there is no problem with the battery itself.

Iphone 5 battery problem with iOS 7

I am experiencing horrible battery time since I upgraded to iOS 7. I feel like I'm down to almost 60% of battery power. Anyone else experiencing battery power issues with their iPhone 5 and the new iOS?

Strangely enough, the phone seem to have stabilized by itself, as if it had to learn my ways before getting back to normal. I did turn off some notifications, as well as some localizations, but that did not have any effect on my battery. After 2-3 recharges though it's now back to normal.
@razmee209, Thanks for your help.

Why does my iPad 2 get worse battery life with iOS 7???

This new update has way too much white on the screen even when fully dimmed it seems to use more battery than before. Can there be an update to change that?
And in case anybody asks, NO, my battery has been properly taken care of. Charged perfectly each time. So that's not the issue.

Don't know how much the tips in this article http://osxdaily.com/2013/09/19/ios-7-battery-life-fix/ might help but it's worth a look.

How can I extend my battery life with IOS 7 on my Ipad?

I didn't have this issue when I was using IOS 6. Ever since I upgraded the battery just drains away without me even using it. I've never had this problem before. I even went in and shut off all my apps etc.

When turning off any location or notification services, if you aren't turning it right off completely, be sure to check thru the hidden list and then those off as well. I can't look at which it's in because I did this last night on my iPhone and can't read my phone anymore. It's an eye strain to look into that.
There is a hidden one in location, called favorite places. That's a waste, unless you want it.
Turn wifi off when leaving the house to go to places where there is no wifi. It's constantly searching.
Turn airdrop off as well.
Last night I found really good tips on imore.com site, but I lost the page it was on to copy here. The result is I actually woke up this morning to an almost full battery on my iPhone. I need the list to do my iPad now.

Is anyone else having problems with their battery life after IOS 7.1 software update?

After the software update IOS 7.1, my iPhone 5 battery life has been terrible. I've turned off all push notifications and location services (basically everything that would affect the battery life). I've done an optimization test and have restored my iPhone and lowered my brightness. My phone has been standby for 5 hours and it's at 54%. Before IOS 7.1, it lasted the entire day before it even hit 50%. I just wanted to know if anyone else is having the same issue. I really don't know if it's the software or the battery itself.

Mines fine, I did a hard reset after the update and with both bluetooth and wifi and celluar data on I am geting slightly better battery life on my iPhone 5s. right now Im at 83% with 1 hour and 24 mins useage and 1 day 14 hours standbye. Siome apps leach battery life so check whats using background app refresh and notifications, apps like facebook and also GPS useage suck your phone dry quickly.

HT1414 Is iOS 6.0.1 Killing anyone's battery life. No change other than installing iOS 6.1 today...now I cannot get 5 hours of battery life with everything disabled!!!

This isn't an issue. Notice the screen prior to the one that shows usage has an iCloud section and a Manage Storage button. For this button to activate ios needs to download a few kb from icloud. Switching back to this screen forces ios to download those few kb.

Loss of battery life in iOS 4.2 (compared with iOS 3.x)?

Hi,
Similar to another poster here, I found that when I upgraded my (first-generation) iPad from the original iOS 3.x software it came with to iOS 4.2, it really smoked its battery life (like, that percentage in the upper right conner really came down a lot faster). I have installed iOS 4.3.3 today and so far cannot tell if there's any difference. I was just wondering if anyone else has experienced this loss of battery life in iOS 4.2 or 4.3 compared with the 3.x software?

Hi, thanks, I had tried that, but it's a good tip... I think there is just such a difference though between how the battery life had been with iOS 3.x compared with how it is with iOS 4.x... and also I think many of the posters in this thread had been experiencing similar problems:
https://discussions.apple.com/message/12690694#12690694
Thanks for the tip though, really appreciate it! :-) Best,

Does anyone know what's up with the iPhone 4s' battery life? Some days it last a long time and other days it drains extremely fast.

Does anyone know what's up with the iPhone 4s' battery life? Some days it last a long time and other days it drains extremely fast.

Not to point out the obvious, but battery life depends very much on what is running and how much the device is being used.
If the battery lasts longer on a day you make no phone calls, but lasts less the day you make 5 hour long calls, this is to be expected.
If however the iPhone has the same level of use on both days, with different power consumption, this would infer a background process (or App) is trying to do something (connecting to server or creating a back up etc).
I switched off all thrid party apps from being included in my iCloud backup, which saves a huge amount of space on the cloud and allows the back up to take barely a couple of minutes.
Battery life seems ok so far on my 64GB 4S (Bluetooth on, Wi-Fi on, Location Services on, Push notifications on, Screen set to just under half brightness with Auto Adjust on)

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

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.)

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

My iPhone 5 battery drain with in 3 hours when I use cellular network on and stand by time is only 2 and half day

I Bought iphone 5 from USA when I came to India I started it then I noticed the battery stand by time is only 3 days. And when I use cellular data then it is live only for 2 and half hour. I bought this phone in January till now I am having the same problem. I have done all the thing whatever the support center told me about restore and all stuff. After that they told me to visit any apple store but there are no store in India and I'm helpless. For my iPhone only I can't go abroad to that country where stores are. Before I used to believe that apple products are the best but this iPhone has just disappointed me. You know my friend making fun of my mobile because they are using samsung product.
Pleade do some thing for me I have left only 2 month of warranty. other wise I will have to through this on dustbin because everywhere it is insulting me.

Sorry, but the warranty for the iPhone is only valid in the country where you bought the device.
In most of the cases 3rd party apps or settings caused the battery to drain faster than before the new software has been set up. Sometimes the mail app tried to connect to the mail server over and over again, deleting and setting up the mail account can solve this problem.
In other cases social media apps did similar things to the phone.
Here are some suggestions for getting back the normal battery life, maybe they are helpful for your problem with your iPhone 5 as well.
