Hmmm i had a fishy feeling If the source was my Skype or amazing weather HD running it on GPS rather than data app. How do I sign out from Skype? I can't find it on wp8 version....My wife's ATT 8X has no issue with battery life unless she's skyping. Gotta reset the phone after she skypes or it drains quick.
I took mine off the charger yesterday morning around 7am and plugged it in around 10:30pm. I was at 49%.
I streamed music during 2 workouts, browsed the web, had a few phone calls, and texted throughout the day.
One thing I seem to notice is it is quick to drain to about 70% within the first few hours of having it unplugged but then battery drain really starts to slow down.
