I've noticed that my battery doesn't last very long either, espically when I'm texting. I got it off the charger at 4:00pm last night, and with maybe 40 texts, and 3 hours later it was at 40%. One thing I noticed, is that I plugged it in at home, and it only took about 30 minutes to charge to full again. Could it be that it's not getting a good connection, therfore not really getting a full charge? My Samsung battery took about 4-5 hours to fully charge, and it would last a whole day no matter how much I used it. I'm around a charger all day, so it's not a huge deal, but I'd still like to figure it out.
