Last week I was freaking out because normally overnight my battery drains about 3-4%, but for some reason it was draining 30-40%!! The only thing I thought of that I installed or updated was LockInfo, and after I installed the newest update it was fixed. Scared me for about a day or two though. I think 7% isn't bad for overnight.

If you have mail fetching, how often does it check for new messages?
