I did some research before going to get my TB and saw everyone was complaining about battery life. I figured I would pick it up with the extended battery and do some tests. I've only had the phone about 3 days and have had the extended battery in it since I brought it home. It is 2750 mAH and quite large. It makes the phone a good 1/3rd thicker and about twice as heavy.
Normally this would make me go "screw that" and return it. After 3 days of playing with the phone pretty constantly (being a new phone and all) I have yet to plug it in at the end of the night (usually between 9-11pm) with less than 60% battery left. That is pretty impressive to me. I haven't, however, used the regular battery yet.
I am quite curious when I switch it back in what my battery life will be like. If I can make it through the average work day without going below 40% I might return the extended battery. I had to go all over the place to find a leather belt holster that would fit this monster with the bigger battery. The Droid X holster wasn't thick enough, and no one offered any normal option for it. I ended up finding some knock-off $15 leather holster with elastic sides at my local flea market that fits it pretty perfectly. I just hope it holds up.
