iOS 10.1 Battery drain

Hello.


Updated my iPhone 5 to iOS10.1 and have been having battery problems.


1 - It jumps from 30% charge to 1% in a few seconds then shuts down.


Now here is the stranger part.


As soon as it reboots after connecting to a charger it show 30% charge. When I unplug it right away it still shows 30% and runs like nothing happened for a good few hours.


So it goes from zero charge to 30% in the time it takes to reboot? Strange.


2 - Shutting the phone down at night with a good 80% charge, it won't reboot in the morning due to no battery charge. I plug it in and its back to 30% in a few seconds.



Thanks for any suggestion in advance.

iPhone 5, iOS 10.1

if it was only a few iPhone then it might be a battery issue. this obviously a wide spread issue since iOS 10.1.1 update and seems to be getting worse. Does Apple read this? Im thinking not. None of your suggestions work since I have already done this BEFORE you posted. As for Calibrating the Battery it just sounds like you reaching. By coincidence I have run my battery down to 0 and now it won't charge or power on. Everyone posting here has sated plainly that the issue ONLY came about since iOS 10.1.1.

I am also having this same issue. Had my iPhone six for over a year and never had any issues. Updated to ios10 and no issues. Updated to ios 10.1.1 and now this battery problem. I will be listening to music or use snapchat on a full charge. Battery gets down between 28% and 30% and the iphone shuts off. Try to restart it, shows the "charge it" info. I plug the phone in, bam, it says charged to 35%. There is something wrong with the latest ios. I don't want to go down to At&t to wait for an hour to upgrade to an iphone 7 if there is going to be the same exact issue. This fix should be out now and I find it crazy that Apple would be sitting there letting this continue as long as it has.

I have an Iphone 6s and Upgraded to iOS 10.1 and noted 2 anomalies: the battery goes down real quick and, more interestingly, the IPhone is consistently warmer, despite there is no apparent activity running on. The back of the phone is running warm, something I never had in the past, even running emails or internet pages full time. I dont buy the idea that the battery has gone so quickly. The device is only 3 months old...I tend to believe there is a bug in iOS 10.1 causing the cpu to run 100% most of the time, doing just nothing...kind of CPU going circle and looping on itself surging lot of current.

message to Apple engineers: check it out and fix it asap...I will not consider any Apple 7 until you show me you can release trustable software, like in the glorious days.

When you go to Battery, is your Usage time same as Standby time? This is what started happening when I upgraded to iOS 10.1.1 and drained my battery. Same thing happened to my iPad Air 2. Also when I reinstalled iOS and tested with the native Apple apps. Yesterday, after charging both, everything is fine again. It's a mystery.

My iPhone 6S was running perfectly after updating to 10.0.1.

Soon after updating 10.1.1 I noticed the battery dropping significant, after just taking a handful of photographs. Sometimes I'd be looking at the screen and I see a % drop as it happens.


Prior to the most recent update, I never obsessed with the battery life of the phone because it just seem to hold charge very well. But now, using it to do a few things and suddenly there is significant % drop in battery just from a few minutes of use.


The official so-called battery saving tips is not helpful nor useful in this case. The bottom line is that before updating to 10.1.1, I had no issues, and since updating to 10.1.1 there is obvious battery drain. I haven't turned the screen brightness up or altered any other settings etc.

I do have the same problem. In my specific case my phone turns off by itself between 10% and 15% of battery levels.

After i boot it up again it will show for example 11% of battery and dies again. Then i boot it again and it will show for example 15% of battery.

This issue started after last ios update. I am using an iphone 6s and its 1 year old

Friday I went for second time to the Apple Store because I had a Genius Bar reservation.



They ran another test that they could not performed the first time and it was about the usage per hour for the last 7 days and they told me that the battery was ok, that I can accomplish the day with my battery so everything is fine but I told them that if I can make it through the day it was because I barely use the phone, with a normal use the phone dies at midday.



I have the background app refresh deactived and some other features already deactived but my iPhone 7 still drains battery very quickly. I went off the Apple Store very ****** off.



So it is a software problem that is frustrating me so much.
