Hi all, new here and new to the android system. I've own my S7 edge now for about a month and love it! However, for the last couple of days I been noticing my battery draining rapidly, I'd say 2-3% every 5 minutes- with moderate use. The only thing I've installed new was the "Trend Micro Antivirus" and it pretty much went south thereafter. I also noticed 'Android System' using a lot of my juice. It's always on the top with more than 30% since last charge. Any ideas on how to fix it. Any suggestions is greatly appreciated. Thanks everyone!
