This morning I was charging my phone as usual and tried to turn on the screen. Nothing happened! Oops! After a couple of passes I could see it trying to boot, but the battery was dead?? After a bit I unplugged it and put it on a wall charger. Some time passed and then it came to life! Whew! All I can figure is an update killed the battery?? Hours later we are still building up to 100% on the USB charger. I haven't had a battery problem and am not a heavy user. Probably the biggest use is the golf GPS, but only use it a few times during a round so it easily goes the distance. What in the world are they doing with these updates??
