Q: iPhone 6s Plus battery percentage getting stuck

Same problem here with my iPhone 6s Plus 64Gb iOS 9,2 from the very first day.

Only thing that fixes it is the restart. I've tried everything that I read in this thread. After restarting the phone the problem seems to go away, but no, randomly it gets stuck.

Hope that someone in Apple fixes this. It's a shame that their phone flagship has this problem.

It looks like the Date/Time trick is what's messing our up. My wife has stopped doing it the past few days and the phone is fine. Hopefully that works for the rest of you! I will report if it happens again. Thanks, everyone!

Thanks, Lawrence! This seems to have fixed it. Hopefully the solution sticks.

I play candycrush and so try to change the date.. If I do that , i experience this problem. If I dont touch date settings, I dont experience the problem

Well, as the phone uses the clock to calculate battery percentage, that explains why you have the problem.

If your iPhone 6s or iPhone 6s Plus battery percentage doesn't update - Apple Support

Official Apple statement. 

Its a software issue and they are looking into a fix.

Hello, today I rad about the % of Battery and the Battery Problem of iPhone 6s.

This his is why I want info to about my problem with the battery on using a iPhone 6S.

My iPhone 6S is a 16GB grey Version, using iOS 9.2 and I buy it end of November 2015.

I Can't say anything about the problems of other users because my phone will catching and show me 100% but I see moe and more often a other Problem.

I Use my iPhone a lot. For me it's a small pocket office, emails, calls, games or news I still use my phone a lot. From time to time my battery goes into less then 20% and change to yellow for safe battery. In 14-16% Area my iPhone shut down without any info and then it's very difficult to start it again. In 1 of 10 times I can restart it and the iPhone comes back online by 12% but shutdown again and I can't restart it without a charger.

I was on the idea maybe and OTA not works well and I reset my iPhone totaly and install it new with iOS 9.2 downloaded from the Apple Page but the fault is still the same.

IF I compare to my iPhone 5S, it was running until 1% and then it was shutting down.

I Don't will say my iPhone do not work well but the % calibration on my iPhone isn't ok so.

i forget to tell, if my iPhone in less then 20% I close all Apps in Background to safe Batterie and just still online to got calls but in the area of 14-16% it shutdown.

ANyone one knows about this problem? Or it's only my iPhone?

I Should talk to apple support?

Hello everybody,

I recently had this issue with my 6s plus 64gb but it only happened to me when I changed the time. I had 80% battery for a whole day which was kind of strange and I googled it and saw that it's a bug and you have to restart you're phone which I did and then it dropped to 68% but after that it's ok! But I'm sure that apple is going to fix this issue. 

Thanks god, I thought I was the only one with this issue. For the record, mine is a 6s from Spain.

Anyone received and official answer from Apple? is a software or a hardware thing?

Look at the message 3 posts above yours.

My iPhone 6 has had this issue for almost 6 months but every time I asked Apple they said it was normal. Guess not.

Same problem. iphone 64gb 6s, battery percentage locked at 4% in the evening. This morning I turn it on and from 7% drops to 5% and off. I connected to the charger, unplug power cycled. Now measure correctly, 3%.

I never moved the time of the iPhone (iPad only with real racing but 3 years ago). This problem happened yesterday morning while I was away from home.

But I used the time-accelerated with Apple Watch (via ring) to see temperatures of hours, I do not know if this can affect the bug.

For the rest of my iphone 6s (chip samsung) I quietly 8 hours of use.

I have an iPhone 6 not 6s. My battery is also behaving like many others who are posting in this thread. I have tried the apple work around with no luck. I don't change the date and time for games like other people. My iPhone is a replacement from Apple it has a TSMC designed A8 processor which are supposed to be more efficient than Samsungs A8 version. I'm betting that the issue is ios software design for TSMC version is not as it should be. I'd bet those with Samsung design processors are not getting this bug. As its 50/50  the iPhone 6 as to wether you get a Samsung or TSMC out the box there will be only a handful of us 6 only users reporting this issue as 6s users as I believe all have the TSMC processor. Example to see if this fits, my phone will report 60 % and then drop instantly to 54% and stay like that for hours. 100% to 80% takes longer to run down and then it hicups at around 60% and below. All of us could be getting different points where things stay put. I've had my unit checked by Apple and it checked out green across the board battery included. Waiting now for the next update to see if Apple gets it sorted. Be good to know if there are any iPhone 6 only users experiencing the same as 6s users.

Just exactly how do you determine which processor is in your phone? Samsung or?

Download an app from the App Store called Lirum info lite free to download. Tap menu and go into CPU scroll down to the bottom.
