Advanced Battery Status

Find Android Smartphones with poor battery Life?
Find Battery Status Unreliable in representing actual battery life?
Every wonder why when device warns about low battery (around 10-15%), your device often shuts down within next few minutes?

Well, you are not alone, in fact, you are correct that Android Smartphones are poor in representing battery status.
Most of the Li-Ion Battery driver works between 4.2V to 3.4V and sample linearly. However, Li-Ion's discharge is non-linear (as show in the app).

This App samples battery discharge rate and give user a much better representation of the battery life.

Current Battery Status is the one shown by OS.
Actual Battery Status is adjusted for battery discharge properties.

Hopefully, with more accurate battery status, you can make better judgement in using your Android Smartphone.
