I run a couple of battery drain analyzers in addition to the stock battery app. They all seem to indicate different apps are the primary battery drain culprits. How can this be? Or am I simply misinterpreting the info the battery drain apps provide? Check these screen shots I took back-to-back a few minutes ago: Battery Mix: WLD: Stock battery app: Look at the WeatherBug app as an example. How can the battery drain of this app be reported so differently? Also, I've been noticing lately that Task Manager has been a heavy drain... at least as reported by one of the BD apps. ?? Does anyone else see this as confusing as I do? Does your GS4 have similar conflicting reports with different battery drain apps?
