IOS10.2 Battery issues

[chirugali]

As Sonos as I updated to IOS 10.2 on my 6S randomly it reboots even though the battery power is still there at >50%. I have to connect charging card to turn it on.
Is there any solution to solve this?

You might have the 6S faulty battery issue.
Contact Apple and see if your serial number qualifies for a new free battery replacement.

i had the same issue, then i checked my serial number on this Apple page and confirmed my battery needing to be replaced which I did get. Funny thing is I never noticed this issue in iOS9.
