BatteryGraph is an application for Nokias N9 smart phone.
It records and shows your battery level as well as other data.
This is helpful to get a better feeling of how long your battery lasts and why it sometimes drains faster.
This application is highly inspired by Jeroen Witteman’s great BatteryGraph for Maemo 5 (http://maemo.org/packages/view/batterygraph)
