my battery was 100 % charged today morning at 8am and by 11 am it was 97%.
After that i suddwnly noticed a sharp drop in battery around 1pm and it was 71%.

on switching off and on..it came back to 91% ??!!

This is true, we are all experiencing this problem. Some more than others. I kinda trained myself to restart my phone at least once a day in the afternoon to get better accuracy.

i never faced this issue in 520 !!

does it only occur in 820 ?

Never seen this on the Ativ S Neo either. Maybe a replacement is in order? You don't have anything new running in the background tasks do you? Never hurts to take some guesses.

My lumia 1020 is new but no issue here. Check your location is on and check tap to send is on by default
