Created in the midst of a broken heart, HEBF Optimizer is an application that aims to increase the performance of your device, also by focusing on battery performance, we didn't forget it. The application also features a useful and smart toolbox that you can use whenever you want. "HEBF" stands for "empty heart, full battery" VIP Battery Saver: VIP Battery Saver puts your device into a deep battery saving mode by setting the CPU governor along with several other parameters of your choice such as force-stopping apps ("hibernating"), forcing the device into idle state (doze) and disabling checked features (WiFi, bluetooth, etc). VIP can be used with Tasker to be triggered in certain events or scheduled within the app itself. It is a very useful option if want to keep your device alive as longer as possible. Game Booster: In contrast to VIP Battery Saver, this Game Booster ramps up the CPU to obtain better instant performance. It can also trigger the DnD mode and force-stop apps as well to avoid interruptions while gaming. This is also a root toolbox: HEBF provides a nice interface for power users to tweak their device. There are some advanced stuff like the Window Manager, ART Compiler Filter and well known stuff like a CPU and RAM Manager, Fstrim and a Cleaner section.
