I don't know what else to do. I've got the newest update that was supposed "fix the battery drain issue", it didn't. I did a factory reset, again, this makes 4 since Dec., didn't help, I've cleared the cache, didn't help. in an hour and half I'm down to 75%. This is my LTE ATT watch, I don't use the LTE, I have it turned off and everything shut down as far as I can. I also have a Classic Bluetooth only that I've had for about 2 months that is setup exactly the same and after a full 9-10 hrs I am at 85-90%.
