Hello I just got my Samsung captivate in the mail. The phone was dead when it arrived so I Charged it to 100%. I have turned off wifi, gps, sync have black background, no bluetooth etc. It was fully charged at 7am. Its now 11:30 am and its at 36%. Display using 95% usage (set to lowest brightness and auto off), standby using 4% and idle using 1%. I have had the screen on for 46 mins 45 secs and its already dead. It's not going to last the entire work day and I am not very impressed. Is there anything I can do?
