When I first got this phone, I could pull 18 hours with 4-6 hours of screen time. Now the battery is dead in 12 hours, even with minimal music playing, 1-3 hours screen time, no BT, solid wifi signal, etc. This seemed to happen right after the Verizon OTA update a few weeks ago, but I'm not 100% sure. Battery graph looks normal, just way steeper than it used to be. I've had several 3 way calls with VZ and Sammy, they've pretty much said if it's not fixed with OS or firmware updates, I'd be allowed to early upgrade at a discount again. Nice offer, but I'd rather have this device functioning. Thanks.
