Is anyone else as impressed by the battery life as I am? I managed to make about 21 hours yesterday/last night with normal use, and a half hour of video viewing. So far today at work I've used 20% of the battery by now (bit past 11:30am), and I took it off the charger at around 7:30am fully charged. My D1 used more power than that, but it was overclocked to 1.1GHz. One comment about battery usage... WiFi is using a huge amount of power for some reason. Display has used about 26% and WiFi has used 21% so far. I know that % is of the 20% I've used overall so far, but that seems really high for WiFi usage. I've been sending texts/emails and a little bit of web browsing/gaming and I would have thought that the display usage % would be much higher. It seems to me that my weak4G signal uses less power since most of the time it's in 3G anyway.
