Ever had a call to your boss\(angry) better half\client\important person dropped due to your phone being drained of power? Don't want that do you!!
Thats where Batt5% comes in. This app will do it's work only when you are in-call.
Once your battery levels goes below 5%, app will send vibration notifications at set intervals.
App allows you to configure notification intervals and vibration strengths too.
