Battery Life is a hot topic for Android. While it’s obvious that using the phone is of course going to drain your battery, have you ever thought about how much juice your phone is sipping while in standby? That’s where DrainGuard comes in. While your phone is in standby, DrainGuard collects information about your battery consumption. That collected data is then presented to you when you wake the phone again. There’s more to it than that though. If requested, DrainGuard can produce a 2-stage log file, as well as notify the user of excessive battery drain occurrence. If your android device is trickling away during standby, this app may help you pinpoint the cause. I recommend trying it out regardless. The data collected is pretty interesting . Check out a more in-depth explanation of the app in the application thread.
