A high battery drain is often a limiting factor for a great user
experience.
With BetterBatteryStats you can analyse the behavior of your phone
find applications causing the phone to drain battery while it is
supposed to be asleep and measure the effect of corrective
actions:
- Spot drainers based on detailed information about the root
cause
- measure the effect of actions to reduce drain following a simple
method
- detect changes in the awake/sleep profile and quickly find the
causes (rogue apps)
In other words BetterBatteryStats helps you gettings the best experience with your smartphone.
