My battery use has been OK after the first weeks charges, yesterday i updated to 2.2, all went really well and was completed in around 10 mins.
First thing i noticed the phone was running quite hot, as if i had been using it for a prolonged time and i noticed my battery meter had halved. Within a couple of hours the battery was in the orange, put it on charge and left it for the night.
Next morning it was fully charged but still warm.
I thought obviously something running in the background, did i every check i could but could see nothing, downloaded a few apps to check what was happening. Smart Monitor told me my CPU was running at 100% and Spare Parts showed my battery partial wake image was a full bar on 'Media'
Result was that the update had destroyed my sd card, (my phone was trying to access the card all the time) i tried but could not could not gain access to the card from the phone or through a reader.
Changed the card to 4gb that came with the phone and everything is back to normal, just
