just bought new HTC 10 yesteday charged it up and it did a few updates and now running Android 7. When I opened photos app the phone crashed and 5 minutes later restarted and it reported recovered from major error or something. As new I did factory reset and all is fine. 11pm fully charged 100%. This morning 7am battery down to 50%, Never so fast battery drain on Samsung. Checked power usage and Android Os 100%. checked in there and Awake and Wifi were both 100% all others were 0% or 1%. Is this normal for HTC 10
