iPhone 6s battery indicator

[vonglower]

I have experienced the following problem twice:
The battery indicator shows a percentage more than 10%, and suddenly the phone turns off showing that it needs charging.
I have googled the problem, and I found that there is a known bug, but it concerns mainly situations where someone has turned off the automatic time or changed country or something...
The thing is that none of these hold in my case.
Should I go to service or wait for the iOS 9.3?

Have you tried charging the battery to a 100%, use it and drain it till it dies like a couple of times? I would suggest doing that

I did not do this, but I waited until something close to 5%.
By the way, Apple Service told me that there is no problem at all with my battery (they checked it), and that it is a bug. They advised me to either reset to factory settings and then setup as a new iphone, or wait until 9.3, which hopefully resolves this...

Also... it's not a good idea to completely drain the battery on your iPhone. The batteries which are used in iPhones like to stay around 50% charged at all times for maximum efficiency and life span. Follow the advice given to you by Apple.

Well, it's better to maximize the lifespan to keep the battery in the 40-80% range most of the time, but it's not necessarily bad if the battery drains to the point that the phone turns off, at least as long as it's not something that happens regularly/often (and doing it once in a while if the battery meter seems to be off after some time can help with that too).

I suggest go to service, maybe the battery need to be replaced.

This is only true for long-term storage. Apple doesn't advise its customers to keep their batteries around 50% at all times.

Fully charging, completely draining it (without recharging at all), and then recharging it to full might be a good way to recalibrate how the phone measures the battery.
