No exaggeration..I got it the monday after it came out..so i guess the 9th..i fully charged it, let it die totally, charged it full..and repeated the process FIVE times. Now, my battery stays on 100% for about 3 hours, then stays on 90% for another like 3 hours and this is all with moderate use...i take it off the charger at 10am, and i am down to 60% the next morning at 10am when i put it back on the charger..and this is all with moderate use..prob 100 texts a day and moderate web browsing and stuff..brightness 3/4 of the way up, 15 second screen timeout although it saves battery if you lock it when you are done instead of letting the 15 seconds run...gps off, wireless location on, and only 3g..never wifi. what else..umm facebook every 30 min, email every 30 min, and task killer i kill everything when i am done....i'd say the advertised 385 minutes is good for me
