Samsung Stratosphere and Verizon.

Battery remaining: 65%. Time on battery: 10 hours. Yes, I'm pleased with the battery life on the Stratosphere (especially compared to the MyTouch 3g slide i had on T-Mobile previously, which typically wouldn't last even 15 hours). I'm also pleased with the Verizon coverage, which is why we quit T-Mobile (or will quit them this week). I think my wife is happier with her Android phone (a Pantech Breakout) than she was with the Nokia E73; happier than she thought she'd be with a touch screen phone, too. So, happy mobile technology here.
