I posted this in the battery " Battery Life Good? Any Battery Saving Tips?" but think it is important enough to merit it's own thread.

My phone was nearly useless. It drained the battery in hours (despite having all apps closed)...and was hot enough to be used as a hand warmer.

Today, at the suggestion of another Pre/Central guest, I removed the Hotmail account.

My Pre is now running cool as a cucumber and removing it from the charger at 9:35pm it still reads 100% charge at 10:20pm. That is an amazing transformation in power usage!

FYI, I had one clue. When going to the Hotmail account I often noticed the synch symbol still spinning. Should also mention that I have over 3000 unread emails in that account.

Hope this helps someone else and Pre development team, please investigate and fix this.
