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.

📌 CPU (processor governor control)

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.

Root Booster can decide which governor you should use and automatically applies the most suitable governor for the selected mode.

📌 RAM (memory manager)

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.

Root booster will test your RAM and sets up your VM heap size for better stability and performance.

📌 Know If Your Apps Are a Potential Privacy Risk

Check installed apps to see if they could pose a danger to you. Be able to see where your app information is shared by using dfndr security’s app location map.

📌 Lock Photos and Apps From Intruders

Never worry about lending your phone to a friend or family member. With Repair system, add a protection password to your photos, apps, and private messages to prevent unauthorized access to sensitive content on your phone.

📌 System Cleaner

Cleans empty folders, gallery thumbnails and uninstalled apps trash to speed up

your device and free up your storage.

📌 Hibernation

Hibernation disables and freezes apps running in the background to improve battery life

and purify your device.

📌 Cache Cleaner

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.

有许多应用程序可以节省电池或提高性能，但是Root Booster使用最成熟的设置来获得最佳效果。您可以通过预设模式轻松应用这些设置，以确保速度提升，电池提升或稳定性提升。这些模式是通过将适当的设置应用于主要电话组件来实现的。以下是Root Booster对您的CPU，RAM和Android OS系统的特殊作用的一些说明。

📌CPU（处理器调速器控制）

调速器是用于调节CPU频率的驱动器。调速器决定达到最大或最小CPU频率的速度和时间。设置合适的调速器可以使您的设备更省电，更快甚至更稳定。但是，确定合适的调速器有点棘手。

Root Booster可以决定您应该使用哪个调速器，并自动为所选模式应用最合适的调速器。

📌RAM（内存管理器）

每个应用程序都将VM堆用于其数据和工作。更改VM堆大小的主要原因是稳定性的提高。许多大型应用程序需要大量内存（VM堆）才能进行工作。如果VM堆大小小于请求的内存，则会导致应用程序崩溃（内存不足错误）。设置堆大小是一项艰巨的任务，没有手册来设置以获得更好的性能。只有通过测试才能获得更好的性能。

根加速器将测试您的RAM并设置您的VM堆大小，以获得更好的稳定性和性能。

📌知道您的应用程序是否有潜在的隐私风险

检查已安装的应用程序，看它们是否会对您构成危险。通过使用dfndr Security的应用位置地图，可以查看您的应用信息在何处共享。
