Battery life is one thing I am pleased with about my 8x. It lasts all day easy with fairly heavy use. For example yesterday I took it off the charger at 5am. About an hour of phone calls, about 30-40 sms/mms, about 20 photos, an hour and a half of podcasts, and probably about an hour and a half or 2 hours of other various activities like Facebook, browsing, games, etc. I plugged back in at 11pm and had about 15% battery left. Better than any android I have had (except my Droid razr maxx. That thing was a BEAST)
