Just got my Bionic today and so far I LOVE it. I actually think the battery life is FANTASTIC! I had to return a TBolt when it first came out because it only lasted 6h or maybe 8h on standby! YIYEKS.
Anyway, charged battery for first time today from 11:30-1pm. Then played with in continuously pretty much till now (9:30pm) with 50% battery left.
Disabled all GPS except Verizon location (GPS is a huge battery killer)
Autoscreenbrightness on although tonight I took it off and turned it on bright manually because I don't like a dim screen
Wifi on all day at home
4G on all day (we live in 4G but wifi is on at home). Taking dog on walk switched to 4G. Shopping - 4G.
Left on haptic feedback. Love that so if battery is good, will leave it on
No bluetooth use
Made phone calls, downloaded a million things, surfed web, etc. Pretty much heavy use.
Did NOT download videos or watch youtube, etc today.
So far, to have 50% battery after 8+h of use is really great in my mind.
Tomorrow I am going to turn off LTE and report back using wifi and 3G. Should be even better.
