So yesterday i picked up my new AT&T 64g one from the store i preordered... i set everything up adjusted settings then used it till the batt drained to about 6% and gave it a full charge.... so i used it the rest of the day and was about to go to bed with 60% batt remaining... right before i went to bed i noticed the GPS icon in the notification bar, no apps were open and i looked through processes and couldnt find anything that had it running.. i tried restarting the phone 2 or 3 times to no luck.. so i went to bed around 1 am with 60% then woke up at 7am to my phone shut off and had 2% when i tried to restart it... I have no clue wtf caused it to do this .. its charging now the gps logo has not come back except when i use a app with that uses it but it promptly goes away when i close the app.... im clueless...
