FatBatt helps users be informed about how much time they can truly work while their laptop runs on battery power. This way, they will no longer be interrupted mid-project because they need to find a power source and charge the battery.

Due to FatBatt, one can also receive notifications regarding the applications that eat up the most battery power (so as to allow them to close them if they are not very important).

One can also rely on the application to find out how much battery time they can save if they dim their screen.
