Well I've had my Thunderbolt for five days now, and since the beginning, the thing has sucked its battery down almost as soon as it was unplugged - even when it was only on standby. Well last night, I left the phone sitting around while I did other stuff, and when I picked it up again, it was completely drained. As in, it had powered down and wouldn't turn on again. Anyway, I plugged it in overnight, and today, I managed to go for a full six hours off charge, and the indicator has hardly moved - and this is with some Facebook play and a whole bunch of texting. Go figure. Anyway, I can honestly say if this is for real, and the battery continues to perform this well, then I've finally found a perfect phone.
