Thanks for the suggestions. I should have said that I already have data and sync turned off as well as wifi, gps & bluetooth.
One of the reasons I bought this phone was for the long battery life, 16+ days shown on the T-mobile website site.
I was recently in Canada and the battery was dead every morning even though I made no calls and sent only 1 text message.
When I go to System/Applications it show a number of apps running such as Gmail etc. Don't those apps running take battery power?
