I have had a StraightTalk Samsung Galaxy S3 for about a year now. Recently my battery started dying really fast. It could have a full chrage and then I'd make a quick 2 to 6 minute phone call and it would drop down to like 80% battery charge. Wtf?!?! I have absolutely no clue what to do. I ordered new batteries. I got 2 new batteries and have tried both, but my phone still drops like crazy. I have turned off Wifi, GPS and all that. I've set my screen lighting to a the automatic setting. I've rebooted and done a complete factory reset to my phone, and nothing is working. I'm going crazy! Someone please help ASAP!!!
