I just updated my 1G touch to 2.1 the other day when it came out and the morning after I went to use it the the battery was at 3/4 from a FRESH charge. So I said whatever and kept using it, later that day I went to use it again and the battery was at 1/4 from 3/4. By that time I was at home and charged it and synced it, I also restarted the unit and that got rid of the issue until today when I just turned it on and the battery is at 1/4 from a 3/4 charge again........wifi and fetch data is off, no apps are open and I haven't touched it since last night. What is the deal and what is the fix for this?
