iOS 10.1 Battery drain

Just wanted to let you guys/gals know I did a reset all settings on my phone and it seemed to help. It reset location settings, notification settings etc. I chose specific location settings like find iphone, weather etc. Reauthorized certain apps to have push notifications (1 at a time) and it seems to have helped. I was charged to 100% and down to 13% now without a shut off. No idea if this actually fixed it, only time will tell. I am going to let it drain all the way down and recharge it. Try the settings reset and reauthorize the specific things (location/push notifications etc) you want to use, reconnect to wifi etc. See if that ends up helping or not.

WAIT! I lied. I was playing music, opened snap chat, PHONE SHUT OFF! Says I have to connect it to power and its back on again. That is certainly a bug.

Hi,

i've a friend working at the apple store as a genius.
He told me these things could be result of OTA updates which can somethimes go wrong in some parts of the OS.

A solution to solve this is do a FULL WIPE of the phone, Restore it with iTunes and Configure it as a NEW iphone.
Even avoiding to restore a backup.

If this doesn't work, go over the apple store and get your battery tested and maybe replaced if needed.

Has anyone tried the full wipe + via itunes + configure as a new iPhone (without restore to backup) ?

Thanks

Yes, I already tried that but no luck.

I did that clean install with restored backup yesterday. After all that i did a reboot with Power button + Home button.

So, yesterday it was the first day after i did all that and all i can say is that my iphone 6s just turned off when it got 0% of battery. I'll wait for today results and see. I'll keep posting in here to let you guys know. #crossfingers

Full wipe, clean install, configure as new, hard/soft reboot, no apps running -> still draining the battery almost 10% per hour without any use. Not an issue with the battery according to Apple dealer here.

There is no fix for this kind of battery drain yet. My iPhone 7 is useless. I can now get max 12h uptime with 2h usage.

I upgraded to 10.1.1 on iPhone 6s. Battery trouble started because iPhone did not go to standby-mode. [Standby and usage were the same]. Downgraded to 10.1 with full wipe. Same problem. Upgraded to 10.1.1 with full wipe. Same problem. Downgraded to 10.1 with full wipe. This time with succes. iPhone has more power than ever. Runs two days on one charge with medium usage. Funny thing is that iPad Air 2 had the same problem with the standby mode in iOS 10.1.1 and also drained very fast. After charging it two days ago problem was solved too. Very mysterious.

So after the 3rd complete wipe you fixed the problem.

Did you reverted back to a backup after the full wipe or did you configure it each time as new ?

No. If you have a problem, never use the backup. Check the battery life with just the native Apple apps for a couple of hours. If it works and you don't lose a lot of power install the rest of your apps. My iPhone is still doing fine. Good luck. It's very frustrating.

I already done this but the battery still drain fast. You can see the battery percentage drops very quickly.

I performed a battery calibration.

- Let your battery drain until it shuts down

- Charge the phone to 100% without using / touching it

- Let your battery drain angain until it shuts asap. (by launching heavy games, gps apps, music, and never lock the screen setting)

- Charge the phone AGAIN to 100% without touching.

I unplugged my phone from the power source this morning 6:30 AM, we're 10:30 AM right now and i'm at 80% charge left. Seems good for now, I have little more faith but i'm afraid for the rest of the day.

Keep you posted if the drain would speed up again later in the day.

None of this works...at all...have tried it all.

2 months with Apple Care support. They keep asking me to send some info, print screens and reports for the "engineers" and no answer until today. 2 months! I pay Apple Care for what? Apple is completely lost

Ok,

I'm at 55% charge left and it's 13:30

Usage: 1h 51min

Standby: 7h, 3 min.

Not sure if this is positive

The same issue with my 6s 64 gb. And Apple support service in Kiev(Ukraine) told that there's no issue 😟

It's pretty reprehensible that Apple time after time refuses to acknowledge issues with their products...they truly are just resting on their laurels...I'm so glad this is only happening to my work issued phone...my personal is Android.
