Since paying attention to my battery life because of this thread, I found that HD widgets was consuming an unreasonable amount of battery life (after turning off my GPS, this suddenly became my top application...)
Basically, in many cases I expect the screen to be the top talker - say 3-4 hours of screen on-time... I've been only getting just over 2 hours... which doesn't seem even close to what I'd expect... I want to say with .67 I was getting more than 3 hours of screen on time on a regular basis, and a few times around 4.
I need to wipe and start from scratch... but Sony's rumored releases and delayed releases for their software versions drive me nuts. I mean the latest 4.3 (101) hasn't officially dropped yet for the 6506, and 4.4 is rumored to hit sometime mid march... Not sure what to think or do...
Oh, and if you're having an issue with Mediaserver - that can be one of several things... could be a corrupt image, could be a flaky MP3... try wiping the cache for your media server and reboot and see if it straightens out AFTER it's cached everything...
