My Android System was running at nearly 65% and I was having bad battery life. I logged off Facebook and it was running at 15% with what seemed like improved battery life for a couple days. Now the battery usage is back up to 40-50% and my battery life is suffering. I have essentially turned every feature off and have no background apps running. My friend that works at Verizon seems to think its a hardware issue. Any tips? this is causing me headaches.
