So if I visit this forum on my iPhone 7, then press the home button and put my phone in my pocket, then come back to my phone 2 hours later there will be serious battery drain. Went from 100 to 84 in an hour. My battery usage says safari audio. The only thing in my safari is MacRumors. Nothing else. My 7 has no battery issues. I get 8-10 hours of usage everyday. But once in a while this happens. Anyone got a clue? MacRumors mods?
