Do you want to know which app or process is using the most battery on your iOS device? Well, there’s a new tweak called DetailedBatteryUsage that provides you access to a battery usage menu used by Apple during development. Thanks to developer Hamza Sood, you can now find out what apps have been using the most CPU, GPU, Display etc. The tweak can do a lot more.
DetailedBatteryUsage unlocks a hidden menu in the Settings app, under General>Usage. The new Usage menu now shows a graph along with detailed information of what’s using the battery. For a regular user this may not be very important, but if you’re someone who likes to squeeze extra battery life from your iPhone or want to find the culprit for all the battery drain, then this tweak can come in very handy.
You can also view detailed battery usage information for every app on your device and look at graphs etc. Details about system daemons, which are basically background system processess, can also be viewed from the menu.
If you want to give this tweak a try, download it for free from Cydia. This tweak will only work on iOS 8 or later.
