I finally got 8.1 onto my wife's Ative SE thanks to Jeemo's guide for getting rid of Preview for Developers. After running it for about a week the phone quit holding a charge. At first it just stayed at 3% while hooked up to a charger, after about a day of this it started looping from power up to shutting down. I tried keeping the phone in airplane mode to minimize power usage. I tried a different charger and cable. Both 2A. I tried taking out the battery and looking in the micro USB port for debris. Finally I decided to try charging it in download mode (power up while holding and the volume up and windows button). I was able to get a full charge in download mode, but it is an annoying solution -- plus I wonder if over time the static screen image might burn in. Any ideas on what might be causing this or how to fix it? Thanks.
