iOS 6.1.3 battery drainage

all i know for battery life, constantly closing my apps properly keeps life, also not always having location services on and keeping it on silent with no vibrate helps. obvious they are though

screen brightness and also since i experienced this issue with 6.1.3 i did the following and it worked for me (listed this on page 3 but ill re list of people havent looked through the post)

go to settings - mail, contacts, calendars

go into icloud mail and turn each switch off one by one making sure you select the save to iphone option not delete

then repeat this on each email account folder

once all are at off ensure all apps are closed and hard reset phone (home and power) this will restart the phone after a few seconds

let it start up and then go back into the same settings and turn each switch back to on

im not sure if it will work for everyone but it worked for me so if youve not tried it, its worth a go, and seems less complicated than deleting all your apps and having wifi and 3g off etc

hope it works for you

II experienced the same problem after updating to 6.1.2. Drastic change in battery drainage. I tried hard reset - no help. I tried turning off all location services, LTE, wifi, Bluetooth etc. still didnt help appreciably. Mi even restored to a restore point prior to the issue, no help.

i finally took the iPhone 5 to Apple Store, the genius guy ran some diagnostics, but found no hardware issues. Stated it likely was software but not related to the new iOS, but an app. that was not closing properly even when the phone was reset or powered down. He advised to restore the i5 to a new phone and see if that helped.

IT did, it fixed the problem. And it has stayed fixed. It was about a week after I updated to iOS 6.1.2 that the problem started, so I really didnt feel like it was the iOS update that caused the problem. Although it still could have been.

LSS, its a pain to have to,restore the phone as new because you have to re download all the apps, reinstall the mail accounts and start all over. But it did fix the problem.

Hi everyone,

Just something that I realized since i have upgraded to 6.1.3. When i go to settings and check the battery use, it says that the standby and the utilisation time are the same. Maybe the problem the batterey drainage comes from here. The iPhone is never in standy mode and even if the screen is black, the system is still running. I didn't have that before. I tried a reboot but it didn't change anything. Are you facing the same problem?

Good observation. This means that some app is running continuously in background. You need to figure out which app it is and kill it. Start by killing all of the apps in the Quick Launch ribbon. If the problem persists it is a built in app, most likely Mail if you have a Push account such as MS Exchange, iCloud, Hotmail, or Yahoo. Go to Settings/Mail,Contacts,Calendars, tap on the name of any Push accounts and turn off all of the switches (mail, contacts, calendar, notes, etc). Then reboot the phone by holding HOME and SLEEP until an Apple logo appears. Finally go back into settings and turn the switches back on.

This process will kill any pending transmissions that are failing and retrying.

Make a backup of the phone. Restore the phone as New. Do not add any apps. Do not create any email accounts. Do not sync the phone. Charge to 100%. Watch the battery life. If it drops at a significant rate (more than 1% per hour) with nothing installed you most likely have a hardware problem. If this resolves the battery drain restore the phone from your backup, and test again. If the battery problem returns you have corrupt data in your backup.

This worked very nicely. Battery life back to normal.

Thank you for your expertise Lawrence Finch!

It's a software issue with the newer phones. Happens to my 4s but my wife's 3Gs on 6.1.3 doesn't do it.

Forget all the fixes here. All it will do is have the same issue again in a few days.

The issue is that iOS for some reason, reports the wrong %. For example. Yesterday I noticed it was doing it yet again. Sure enough, just above 3 hours usage and it was at 11%. So, what I do is: wait until it is at less than 15% battery. I noticed it was at 11% so I did my fix. I close all open apps and press the lock and home buttons at the same time. Hold them until the phone shuts down. When I turn it back on, the percentage is now at 18%. I knew then it was fixed. Now I'm at 20% and over 4 hours. And when you're doing Internet and Internet video on 3G the most I expect is right around 5 hours or 4:40 min.

Sometimes it would tell you 91% you force shut down and it comes back at 88% or vice versa.

When I see the battery is going down too quickly, sometimes I look and it's at 10% and instead of going to 9% it goes straight to 7% and then 4% and maybe shuts down after that.

Anyway. That's what I do. Wait until its about 10% and force shut down with both buttons. Turn it back on and see if the % changes.

Also, let it drain all the way and shut down. Charge it to 100% and when it is fully charged do the forced shut down thing.

Experiencing the same problems with my Iphone 5. Back in IOS 6.1.2, I heard about the problems some users had with MS Exchange but luckily it didn't really affect me much and the lockscreen bypass issue also wasn't a big deal for me since I rarely leave my phone in the open, but everything changd when I updated to IOS 6.1.3.

Suddenly I find myself using up all my battery in less than 4 hours. When I checked my usage, both usage and standby time were the same -to my shock and dismay, I tried resetting it but it didn't work. Then I figured it must be the Exchange bug so I tried removing my Exchange account and so far its been working to help maintain the battery -but now I can't access emails on my Iphone, which was the very reason why I bought one in the first place to help with my work.

The Iphone 5 was my induction to the Apple ecosystem and I was really looking forward to it. Sadly, Apple support is very hard to come by in my country (Philippines) and so I'm stuck praying that the engineers from Apple figure out a way to fix this issue or they come out with something new altogether.

Update.....I found it was the Calendar App causing all my issues. If I opened Calendar it never stopped accessing server. Closing the App and going to Multi-Task on the bottom and deleting Calendar stops the accessing and no battery drain....try it. It is a pain in the *** to have to do that but, I don't have to charge twice a day either...still at 77% for 10 hours now and I have used it for calls directions and text messaging.

Same problem occured after last update.

However I noticed when I turned off Wi-Fi on my iPhone 4s dramatic battery drainage stopped or maybe seized much. So now I just turn on wi-fi only when I really need it, othewise battery just dies.

On this mode I'm on my 2nd usage day without recharge and I have as much as 40% battery left after 36 hrs of standby/moderate usage. (note that I'm mostly on EDGE mode, I also turn on 3G when needed)

Until Apple gets this fixed my recommendation is to turn off wi-fi. If it doesn't work on your device then it's just my phone, but I believe it could help at least some of you.

Cheers,

Just found this thread after having much shorter battery life on my iPhone 5 with 6.1.3. I already found two fixes here that made a difference. 1st I read a post that said to turn off facetime, so even though I never use it and had it turned off, I decided to check the setting.... To my surprise it was ON, so the update must have turned it on by default. After turning it off I reset my phone and was shocked to see the battery level showed 81%, it was showing 72% when I turned off Facetime. The second thing was from a link above which said to turn off 'documents and data' in iCloud, it's another feature I don't use and had turned off.... It was ON and docs and data was on, must have been the 6.1.3 update again.... I reset again and the batt level jumped to 83%... Very strange as the capacity / charge level should not jump upwards from turning off features????? Anyway I'll see how it works after a full charge and report back if anything significant develops.

On a side note; Has anyone noticed after 6.1.3 that their Auto Brightness control started changing levels much more quickly than before? Mine also seems to jump right to maximum when outdoors in sunlight no matter what level it is set to on the slider control? Never did this before 6.1.3, I thought I'd find this as one of the battery drain issues. This is also happening on my iPad 3.

Yesterday I was in the mall and there is an Apple store in there so....I took my iphone 5 ios 6.1.3 in to the techs. Here is what I was told and how it was fixed: My update had gotten corrupted and the modem was bombing out. So that is what was draining my phone. I hadn't used it and it was at 80% at 10am. The fix was to backup to icloud (which I had done) and then completely restore the phone to factory settings. The tech did it through itunes, so the phone was now plugged in. He said my update was corrupted by doing it "over the air" and by not having it plugged in to a power source. After the restore and all my apps reloaded back onto the phone I was good to go.

However, I noticed that my battery was still draining quickly last night, so I let it get down pretty low and then turned off all icloud settings and did a hard reset (hold down home button and on/off button, until apple appears).Then I turned back on all the icloud settings. (I really don't know if this makes any difference) Then I plugged it in to charge for the night.

It is now 11:27am and I am still at 96% and have used the phone for texting and email. So I have my fingers crossed that my battery issue is fixed. If the problem is all these phones got corrupted updates, then Apple isn't going to be putting out an another update so fast.

So I know this is another fix and it takes some time, but it worked for me, for now. I will update if my phone seems to resort back to draining again. Good luck!

No. I just followed 2 seperate suggestions posted earlier. First I turned off facetime and reset. Then turned off just the Documents and Data in iCloud and reset. I had both these features off to begin with but they were turned on with the 6.1.3 update on my iPhone 5.

Update: I just 'woke up' my MacBook air for the first time since the IOS update and it had popups onscreen about authorizing facetime and icloud with other devices. Didn't really read the whole popup, just closed the windows.... The same (or similar) message had appeard earlier on my iPad 3 (not updated to 6.1.3) but I didn't pay attention either. I am beginning to think that maybe the various battery issues after the update may be due to the phones trying to reconnect / sync with the original shared features / devices. My MBA is set to 'wake for data' it may have been trying to connect with my phone for iCloud data and facetime connections. I had not used it for over a week but it obviously was trying to reconnect with my phones facetime and iCloud or the popups would not have been there immediately when I woke it.....

THANKS Jajaba I had never dug that far !

EVERYONE CHECK in Settings >Mail >Fetch New Data >Go down to ADVANCED they snuck in another iCloud PUSH HERE! Turn it off .. Or set to Manual , whicheans it will check for mail when you turn program on.

NOTE This is NOT the PUSH settings at top .. But a totally hidden one!

I had the same problem when i upgraded to 6.1.3. Battery lasted less than 5 hours after full recharge even when phone is on standby. The problem has to do with the mailboxes. I have disabled all mail accounts and the drain has slowed down considerably to about 1% per hour in standby mode. Try that, it is a temp solution before Apple comes with an upgrade that solves the problem.

I am now getting 90 minutes usage per 20% battery. Which is a **** site better.

It seems my issue was related to the push settings in 6.1.3.

Fwiw I don't have any mail accounts as I use the Gmail app. I've turned push off on the mail, contacts and calendar settings. And in advanced I turned it off for my iCloud account.
