Hey, just bought my xperia x10 few days ago, wanna ask something, how long does the battery usually last? mine feels like drain quickly, 54% after 8 hours and 45 minutes unplugged from the charger, did a little bit gaming, some camera and watching few video, but most of the time are browsing, maybe for few hours, is this normal that it drain this fast? i think have to charge my phone at most maybe once every one and a half day or two
