I just got my new A510 last week. I have charged the battery twice, updated my apps from my old A500 and installed the new OTA update. I have only gotten about 5-6 hours of total screen time on a full battery. This seems very low. It is actually worse than I got with the A500. The battery is one of the major reasons I chose this one as the A500 replacement. I would be interested to know what kind of battery performance others are getting and what tweeks/settings you have used. Thanks!
