iPhone 6s Plus battery percentage getting stuck

Glad you found a workaround. I would never have seen this problem, because in the 8 1/2 years I've had iPhones I've never changed the time setting; I've always just left it on Automatic.

Yes, it's common practice to change time for earning lives in games.

This is my first iPhone (I was always an android fun) and this is really frustrating. You should be able to do whatever you want with your (very expensive) mobile phone. Or at least, do things that are allowed from the operating system, without any trouble. Why changing the time makes a bug been activated? That's not good practice... And, for sure, that's not what I was expecting from Apple.

Keep in mind, that other than that bug with the battery percentage, the phone is absolutely amazing. Super fast, great screen, etc.

I suspect that it never occurred to Apple's developers that people would change the time routinely, so it would be OK to use the clock to calculate the remaining battery capacity. You can't determine remaining battery capacity on a Lithium battery by any measurement of the voltage, as the voltage doesn't change until the battery is almost flat. So instead there's a circuit that monitors the actual current flowing out of the battery as a function of time, and compares this to total capacity of the battery (which can be determined by the time and current inflow to reach 100%). For example, if it's known that the battery has a capacity of 2,000 milliampere hours, and that 200 milliamperes have flowed out of the battery in 1 hour, then 10% of the capacity has been used and the display will read 90%. But if you change the time setting then the calculation can no longer be made. The only way to fix this is to have 2 clocks, one that you can set, and another that is used only to measure battery usage that you cannot change. So fixing it is a fairly major change.

Apple has finally confirmed this is an issue:

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

OK i've a 6s since 16 december and it started to behave like all the rest here yesterday night. I didn't even charge it since i charge it once every 2 days, i put it on airplane mode at 48% and when i woke up one our ago i saw it was still at 48%. After 1 whole hour usage it's still at 48%.

The only time i changed date and time was in december but i didn't have this issue, i've swirched it back long ago so the phone has almost always had normal date and time with automatic syncronization on etcetc. All the standard settings. So it may have been airplane mode, which i actually ALWAYS activate when i'm going to sleep, but this is the first time i'm experiencing stuck battery percentage.

If apple doesn't fix this before the next ios/iphone is released i want a full refund because this is not a working phone on a fundamental thing that is autonomy. So please don't introduce any new sparkling useless feature before this gets resolved.

Sincerely, a guy who gave you 900 euros and is not a thief and always has to provide perfect performances to get his earnings, so do the same

Hi guys, is it normal or bug?my iPhone 6s having the same issue in battery percentage,here is my situation, when i charge my iPhone using Anker 2nd Gen E5 16000mAh from 20%-92% it took me 1.5hours to 2 hours and stuck at 95%-100% for another 2 hours to fully charge but sometimes stuck at 92% and not charging but when i connect it in wall charger it shows fully charge after 3 mins, i noticed that when i charge 20%-92% at 1.5 to 2 hours and disconnect my iPhone and connect it in wall charger after 2 to 5 mins my iPhone is fully charge, i tried to charge different device and no issue.thanks

I've been messing with the date time and my phone has been stuck at 50%. (6s+ 128GB) Cycled the power and it's at 86% and climbing.

If you mess with your time it will throw off the battery gauge, because the battery gauge needs a time standard to calculate state of charge. It currently uses the system clock.

OK thanks Apple! 9.3 updates finally fixed this issue 🙂

For me it didn`t...it still doesn`t show true percentage after charging...it needs to be turned off and on to show it:((

same friend.i also upgraded 9.3.But this problem can't fix for my 6s.

I agree with you.

I have iPhone 6s (64 GB) TSMC model { Updated to iOS 9.3 } & still battery indicator doesn't provide right read for the battery status ????!!!!

for me while charging I keep time set to automatic & WiFi is on, this steps does make progress but still doesn't provide right read for battery percentage !!!

By the way keep time automatic drain battery faster !!!

Apple should take good care regarding this issue & iOS 9.3 doesn't fix this issue.

come on Apple fix this stupid issue !!!!!!!!!!!!!!!!

Yep fri,i m very very annoying for battery percentage misleading issue...

Meantime,Nothing to do and wait for Next ios version.

Which won't fix the problem. The problem is your phone, not any specific iOS version. Take it to an Apple store, or try one or more of the many ways to fix this that you can find with a Google search.

really??....Did u experienced with ur phone like this problem?????
