Phone freezes black, and drains lots of battery
Hey, the latest 48 hours my phone has done something really weird. At some times, when I'm doing something like eating, watching Tv, playing xbox or whatever, I put my phone on the table or in my pocket. But then, when I'm going to check what time it is on my phone, It'a totally black and is not responding to any button, touch or slap. So I pull out the battery and put it back in and then boot up the phone. I have no idea what it's doing but I can see one extreme battery drain at every "black screen freeze" in the battery history in the settings as shown in the picture. This have happened 4 times in 48 hours. Please help!
