I've had the GS4 since the day it came out for Verizon and this is the first time that my battery drained like this. About an hour and a half ago, it was at 50%. Then I checked on it 30 min ago without even touching it and it was at 20%. Checked on it again 20 min later at it was at 7%?? My phone was also acting really weird. The power button was triply and wouldn't work to wake up the screen. It took like 20 clicks to wake the screen so I pulled the battery. I put it back in and turned it back on and the phone was now at 2% and then died in less than 2 mins. Right before it died, I checked it and the screen time was about 20% while android OS was draining it at 31%?? Nothing was downloading and the phone was idle most of the time.
