Today was my first "real" day with the Tbolt.
Screen set at 25% brightness, weather set to sync every few hours and nothing else is set to actively sync, save for gmail.
As of 12:40am, my phone has been unplugged for 14 hours 2 min. and I still have 25% battery left.
My usage today has been using 4G LTE only, no Wi-fi.
Activity included email, phone calls, txts, taking photographs, sending photographs, web browsing, some Guerilla Bob action, file transfers via bluetooth, file upload to picassa, and checking Twitter feed and Facebook.
I'm going to try and push it a little harder on Monday, but so far I'm less hesitant than I was the day I got it. I charged it last night while the phone was off. I'm going to try charging it with the phone on tonight and bump charge it in the morning. I tried to emulate my "normal" day using the phone and get a read on the batter from that rather then go off of a "play with my new toy" day.
I have a strong feeling this phone is going to get better with time. Also, I'm not finding a huge drain in power when using LTE. Always a strong signal.
