10.1 iphone 6s shutting down with 30-40% battery left

[Valkyre]

As the title suggests, last week I updated to ios 10.1 and my phone has started to shut down when battery is at 30-40%... I try to restart the phone and sometimes it works but then it shuts down again.

It says that there is no battery left but the battery indicator keeps telling otherwise.

Now I thought that it was just a matter of battery calibration. Which I did as per Apple's instructions like I have been doing all these years.

So I did this but the phone keeps shutting down which makes me believe that there is juice in the battery after all and it is not a calibration issue.

Anyone has any clue what I should be doing?

Mine did the same. Got a refurbished one from apple - now everything is fine.

Sounds like a faulty battery.

Same thing happened to my wifes. We tried to restore it, charge it off from zero, all the tricks, nada. Was gonna send it in for repair but We upgraded to the new phone and its been running great ever since.

Yup exact same issue on my 6s. Got a replacement (a macrumors member mentioned that Apple supplies "remanufactured" not refurbished phones).

If you have warranty left it should be no problem.
