Description

From the listing uploaded by “appokbestx”.

There are many apps that save battery or increase performance, however Root Booster uses the most proven settings to achieve the best results. You can easily apply these settings with preset modes which ensure speed boost, battery boost or stability boost. These modes are achieved by applying appropriate settings to the main phone components. Here are some explanations for what particularly Root Booster does to your CPU, RAM and Android OS system. Each Android application can have one or multiple services. They run in the background and usually perform some kind of task. Many people think that when they kill an application, it completely stops draining your battery and computing power, but that's not true. Application still have services that are running after killing and still drains battery and computing power. On the other hand, if you hibernate an application it stop it's services and application does not drain battery and CPU computing power anymore. Hibernation is gently and efficient way to save your battery and increase performance. A governor is a driver for the regulation of CPU frequency. Governor decides how fast and when will be achieved maximal or minimal CPU frequency. Setting appropriate governor makes your device more battery saving, fast or even more stable. However, deciding which governor is suitable is a little bit tricky. Each application uses VM heap for it 's data and work. The main reason to change the VM heap size is stability improvement. Many big applications need a big amount of memory (VM heap) for their work. If the VM heap size is smaller than the requested memory, it causes an application crash (Out of memory error). Setting heap size is hard task and there is no manual to set up for better performance. Better performance can be only achieved by testing. Cleans empty folders, gallery thumbnails and uninstalled apps trash to speed up your device and free up your storage. Hibernation disables and freezes apps running in the background to improve battery life and purify your device. Each app creates unnecessary files that use your SD card or internal storage space. Removing cache files by one tap to free up space helps you to reclaim storage and optimize and speed up your Android system. Disclaimer: Root Booster is proved by thousands of users and have the auto backup system, but we do not have responsibility for damaging your device.
