Hello, I don't know if it's only me, but, I was charging my IP6s Plus today, and battery percentage went from 24 to 32 % after few minutes, then it come the distance from 32 to 38 slowly, and from 38 to 42% so fast again. My iPhone is new, I'm little bit scared that it's battery issue, not software. Can u guys help me? And second question, When I'm putting phone to my ear while talking on the phone, proximity sensor should work with little delay? or it should make screen go off immediately, thanks for your answers!
