Q: iOS 6.1.3 battery drainage

disable emails and turn off 3g and wifi if you dont use them also turn off icloud and facetime and imessage this is the only solution for now untill apple releases a fix

I tried doing that last night and the phone was on wifi and the battery did not run out. But what's the point in having to disable 3G and cell info. for how long have you been facing this issue??

Apple seems to have got their work cut out!

Had the problem, it was critical, like 0.33% of battrey loose per minute.

Yesterday I turned off 3G, cell datas, and location device.

Loaded my battery all night, disconeted it in the morning. It was 2h30 ago, battery is 98%.

It makes 150min and 2% of battery loose, 0.01% per minute.

Thanks Eric. just did that and put it to charge. But whats the point without 3G if you're not in a wifi hot spot?

now I can only use my phone for calls and texts. Can't imessage, safari, etc

aA suggestion for all of you who have been troubleshooting this issue and know exactly what they did. A better way to bring things to Apple's attention is to file a report on bugreport.apple.com . We don't know how and how well Apple follow this forum, but the bugreport is there specifically for that.

I just started noticing the battery draining issues recently and did the 6.1.3 update I think a couple weeks ago. I noticed when I tried to turn my phone off yesterday that it just restarted and wouldn't stay off.

I 'am almost sure that there is something around 3G or location.

In the same condition of use, yesterday my phone used 90% of battrey during my work time.

Without 3G and location, today 25% "only".

Nest step of my test : keeping on location and not 3G.

Answer tomorrow.

Thanks for posting your processes.  I have essentially the same list showing on my iPhone 5.  I am curious as to why my Mail, Camera and App Store are always actively running?  The Phone makes sense and the App Store may on by IOS default to check for updates but the Mail and Camera running all the time makes no sense to me.  No idea if they might be drawing any battery power, but they are the only other Apps that are listed as running yet do not in any way show as being 'open' from the user interface or the list of open apps (when double clicking home button).

PS: My mail is set for manual checking only (fetch  = manual),  push is off and no type of notifications or auto checking used.

ok another trick is to disable all the notifications and localisation service.this is the way it is apple should really think about this

I'm well aware of that.  Just trying to figure out why the Camera, Mail and App Store are always listed as 'running' apps with no way to turn them off / disable them.....

these are lunch daemons and can be diabled only if you jailbreak your device

Looks like I'm not alone.

My iphone5 start to drain the battery 2 days ago.  It used to last 2 days with standby mode before this new update. Now I charge every night, and by noon next day, it drains out.  Couldn't even last for the day.  Really frustrated.

Oh la! You typed the whole list.  MINE a bit differerent. I would type it if it helped anyone at software fix dept. Good for you.

By the By I can get Camera and AppStore to go off..

. Open them again. Have them do something ..shut, then remove from base home screen again.

.. after you do that .. RUN your Free Memory clear..and voilå they are gone.

I also have one thing that won't SYNC w iTunes

and one with Everynote.. I have yet to discover what those are..even though it says to go to iTunes,

I have no idea how to get an error report.

Wel,l I will say I am glad the 5's are getting it now too. Maybe we will get a fix. They would ignore 4S I think.

iOS 6.1.3 caused both a dramatic battery drainage on my iPhone4 + connectivity issues (text message, phone call issues).

Personally a great fan of iGadgets with the house & pockets loaded with iPods, iPads, iPhones, AppleTVs etc. As a self-observation, however, I've now reached a tipping point where my personal comms usability & reliability requirements force me to seek for another, hopefully better suited device. Perfectly aware that the battery drain & connectivity effect may not be universal, may not appear in all environments & some tweeks here & there might improve the situation a bit, but doesn't really make a difference - I need my phone & messaging to work.

Have now twice faced the battery drainage problem over the past few years (step change with an iOS update that makes the device useless). The first one was eventually fixed with an iOS update, but for the second time I'm not willing to wait nor to read through threads with minor optimization hints when the problem is fundamental. The simultaneous connectivity issues after iOS 6.1.3 have now almost cost me a fortune with critical calls & text messages failing to go through.

So continue to love the gadgets for many other purposes but personally this is the time to check if other smartphones can better meet my requirements for reliable comms. Hope the bug gets fixed & the iX:s get back their battery span needed for my other use cases.

i feel the same, as a iphone. ipad fan, its a pain to not be able to use icloud till they fix this, i note that there is nothing mentioned in the major mac sites about this at all. are we such a minority?
