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.

IOS 4.3.1 battery drain on iPhone

I have been wrestling with trying to find out what is causing my faster than normal battery drain issues since upgrading to 4.3.1 on iPhone. I thought I had it nailed when I discovered Skype was running in background. I have since deleted the Skype app but am still getting faster than normal battery drain. I then began to look at the internal processes running and am now wondering if any of those are the culprit.
How do you know what the process is used for and if it is needed? And then how to kill it?
Thanks and I look forward to your reply.

Well I'm still testing, but so far still looks crap to me.
It seems the opening animation is still horrible, but on most apps the second time you open an app (if it is already loaded) its smooth. This tells me when you first hit an app that it's loading is interfering with the animation. (never did this before 4.3)
The ipod app is still glitchy animation wise, and settings still has a second or so pause before appearing.
The camera app openeing speed seems to have improved a little though, but the double tap to reveal background tasks is totally inconsistant. (pause before doing anything, then glitchy crappy animation on screen move up).
Ultimately, I think that this is just a case of apple dumping the 3gs, and 'pushing' people to get a more powerful iphone (4 or even 5 later this year). The update doesn't even mention 3gs stability in the release notes, so Apple either basically have their head in the sand, or as I expect, just don't give a crap.
Will test some more, but this isn't looking good.

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 ..........

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!!!!

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!

How to fix battery drain in iphone 4s

I have recently brought an iphone 4s and the battery is draining even without much use. please advice if any one is able to fix it with some patches or updates iOS 5.0.1

I have personally seen the problem and corrected it on numerous models now including the 4S, 4, 3GS and iPad 2s. Corrupt system level settings created by an iOS 5 bug in the original release that caused battery recalibration issues, etc. Just installing the update does not fix the issue in most cases (sometime it initially can be worse). You need to clear out those settings and recalibate the battery. For those still having the "standby battery drain" issue follow the procedure below in order. It does fix the problem in most cases.
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). At this point, 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 (till 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... not all, but most. 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!

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.

Have iPhone 6 and have 8.1 now w/battery drain issues. Advised to reinstall 8.1 in iTunes. How???

I seemed to have much better batter life on my iPhone 6 while on 8.0.2. Upgraded to 8.1 and now having battery drain issues!! Installed over the air on wifi and all seemed to upgrade fine. I've read a fix may be to reinstall on iTunes. How do I now reinstall 8.1 on iTunes when I'm already running 8.1? Any suggestions?

In most cases the problems when switching to a new iOS version are (as I had with my switch from iOS6 > iOS7):
- rogue app process (app not updated yet to iOS8/8.1) check Settings > General > Usage > Battery usage in percentage to determine which app is using much more battery although you haven't used it at all or much.
- settings in e-mail receiving is changed
- background app refresh (turn it off if you do not need it)
- location services (look carefully which apps you want to use this feature)
- notifications (look carefully which apps you want to use this feature)
- Facebook app

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.

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.

Massive battery drain issues after the latest software update - phone hot

After the latest software update (to the NI2 version) I have massive battery drain issues. The phone also stays hot. Even when I don't actively use the phone it seems to stay "awake" according to the stats. When I disable all data (Wifi and/or 3G/4G) it's perfectly fine. Does anyone else experience the same issues or has recommendations?

Is the device trying to sync all your photos with the cloud?
This is what I would do.
Back up your photos and music onto a personal computer. Copy down important settings like for your email, and contacts you can't risk losing.. even icon placement of important apps. Diagram it out.
Then perform a Factory reset on the device. Alternatively you might find the procedure for wiping the low level cache of the device posted in other posts on the site. That might fix the problem and avoid you losing settings and content on your device.
Extremely bizarre behavior post updates are usually associated with low level cache issues that cause the OS to behave poorly. Some people have reported their phones running hot and that could mean the radio is on constantly attempting to back stuff up to the cloud our restore stuff.
Good luck.
