I've had great battery life on all previous android phones and even the S4 for the first few months I've had it. Suddenly, it dies within hours of moderate use. I figured there must be a rogue app running in the background. I finally decided to download battery mix to see what I'm missing and apparently lookout is using 78.6%! I've never had a problem with Lookout Mobile Security before. I want to keep it because I really love the features, but that's insane. Has anyone else had any issues with Lookout?
