6.1.6 update destroyed battery life

Reset your device: hold down the home button along with the sleep/wake button until the screen goes black and you see the Apple, then let go. (No data loss)

I have the exact same problem, phone used to last a day with normal usage. now no more than 3 hours. I tried to roll back the update, but unfortunately itunes had already created a back up with 6.1.6. this is rediculous..

Amishcake, your solution does not work.. battery dropped 4% in 1 minute after the reset.

I hope they issue a fix for it soon. otherwise its just a cheap way to encourage hardware sales!

Update:

Short version:

Battery problems seems to be solved when the phone is restored to the update 6.1.6 but is then set up as a new iphone rather than recovered from the saved backup.

Long version:

After several trials and attempts to restore on the earlier version, toying with jailbreak, that did not work. Even the restore from itunes itself got jammed and I had to restart everything for it to work. I ended up having to restore the iphone to 6.1.6 again, but this time I chose to set it up as a new iphone. I put the bare minimum of my apps and music etc on, so that the phone as lots of free space to use (I have some 10G free).

After the restore completed and the phone synced, the battery drain seems to have stopped. It used to be 2-3% for each min the phone is on. It has stopped altogether, the phone has been off the charger now for 2 hours and with talk/music/vibrate quite heavily used and the batter is still at 100%!

WIll update again after a longer test period. But it will not hurt ot try this solution. Setting up the phone anew maybe somewhat longer but not too painful as the battery drain

I've read on a news post in my Xite newsreader that users have solved this rapid battery drain problem by quitting all apps followed by a reset of the phone.

Double click the Home button to show the screen with running and recently used apps. Each app icon will have a sample page above it. Flick up on each page (not the app icon) and the page will fly away and the app icon will disappear. This quits that app. Do this for all apps that pear there.

Then reset your device. Press and hold the Home and Sleep buttons simultaneously until the Apple logo appears. Let go of the buttons and let the device restart. See if that fixes your problem.

Hi Ralph9430,

Did that earlier (reset with AND without apps closed) nothing seemed to work, for me at least. But the setting up as a new iphone is working like a charm, so far!

Hey Andy,

Just an update, battery holding up pretty well so far, so by far seems to me this method of setting up as a new phone is potentially the cure.

Re- your contacts if you setup as new iphone, if you are using icloud, your contacts will all be restored automatically once you log in with your apple ID on the phone after restoring, so will some data for apps which you might have allowed to backup to the cloud.

In my case data loss included: old sms's, some personalized texting words that will have to be relearned by the phone dictionary, nothing to worry about really, given the unusability of the phone with the battery issue.

Other than that, nothing else was lost, since I have my contacts and my photos synced via icloud.

If you do not have icloud activated, it is pretty simple, activate icould before you do the setup as new iphone. It will save your contacts and if you have some apps that have that feature (e.g. whatsapp, which can recover all chat history from the cloud, if activated)

So just activate icloud, look into the apps you care about and see if you can back up. I think maybe you can even back up sms's but I am not sure.

Only then set it up as a new phone. this might minimize data loss significantly.

Hello,

I've got the exact same problem, battery drains in a day.

Also when is 20% less battery, sometimes, when people call me he just turns off, people still hear they calling me, but he is totally dead and can't turn up unless I put him to charge.

Apple pls.. fix it..

My iPhone 3GS has the same problems described above: on wifi mode i can use battery till it's completely finished (2%), but if i try to call, send messages or use EDGE/3G network the phone turns off with battery at 25% or more ... With 6.1.3 these things didn't happen, I think that Apple should release another update or let us be able to downgrade to 6.1.3, keep signing that version.

I think that if neither of these solutions are considered users should think not to buy apple phones any more.

I found the same problem of ChoMaNN:

when my phone reaches about 30% of battery turns off (apparently), if I press the power button it seems to boot with apple logo but after one-two minutes the screen becomes black again, so I have made this experiment: when the iPhone turned off with a lot of battery i tried to call it with another phone and i heard it RINGING (not the iphone, obviously, but from the phone i was calling from), so it is NOT a hardware problem but a SOFTWARE BUG! i think apple developer should fix it immediately!
