Apple added a per-app battery usage break down in iOS 8, to help users identify which apps or services are consuming the most battery life. But the company tracks a lot more than it shows by default in the Battery usage screen.

A new tweak called DetailedBatteryUsage by well known developer Hamza Sood enables the hidden battery stats on the iPhone and iPad, showing a graph of battery level against time, and stats like SOC Energy, CPU Energy etc.

The detailed stats are available by going to Settings > General > Usage > Battery Usage. After installing the tweak, you’ll see a graph and the top, and tapping on any application in the list will show you detailed battery stats. There are also other stats like Total Drain, Active Usage and Background Usage. You’ll also see battery usage of system daemons, which are hidden by default.

While many of these detailed stats won’t be useful to everyone, I can see the utility of having a graph of the battery level against time.

You can install DetailedBatteryUsage from Cydia for free. Let us know what you think about it in the comments below.
