I know there is a lot on this topic, and believe me, Ive searched for ever, but I'm questioning my battery a little bit. After charging it fully in the outlet charger from 15%, it got to 100% in a quick 30 minutes. I then starting searching the web and sending texts, a few emails, for about 30 minutes. for another 20 minutes I was cycling through the menus trying to close out of apps, etc. (being paranoid.) Then It dropped down to the 80 mark. (I always have all of those things off like gps, syncing, lowest brightness possible, etc.) Then with 40 minutes of a gps on maps and continuous playing of music on the brightest settings, (was trying to test it), it dropped to 60. I then kept that process going for another 35 or so minutes, and it dropped to 40. So a reminder: starting from 80% till 40% I had full brightness with no timeout on, gps map open, and music playing softly with no headset. Does that seem pretty quick to you?
