My just got my replacement droid X, the last one was stuck in bootloader and wouldn't charge. So yesterday my new "pre-owned" one came in the mail, i switched the battery and SD Card over, and had my new droid X up and running with little battery. I charged my droid x from 10:30pm-7:30am, took it off it's charger and went to school. It was dead by 11:15am. Why?...I've (always) had my brightness to the lowest possible, no task killer..but that was never a problem before? Before i got my replacement droid x the batter would last all day and almost all night. I've even got less apps now on my replacement. Can somebody help and tell me what's going on? It'd be much appreciated. Thank you.
