First off what i am experiencing is not the normal battery drainage common on the s3. At some points i'm talking 25-35% in 10-15 minutes or sometimes more. It's also hard to charge in a normal amount of time like it usually would have before. And sometimes when it's plugged in it won't even charge, just keep draining but at a slower rate, % won't go up. It gets quite frustrating not knowing if the battery will not last for more than 2 hours before it's completely dead. Don't really know what direction to go in this situation. The phone and OS system seem to be working excellent besides for the drainage. It's a 4.4.2 btw if that's any help. Thanks!
