It tests RAM, sets RAM VM Heap size & applies appropriate CPU governor to ensure Extreme Speed Boost.

Root King Booster also saves Battery Power. Enabling Extreme Battery Saving Mode improves poor battery life. Unlike other battery saving apps, this app uses most proven technique to save power. This app finds battery draining apps(also poorly programmed apps) installed in your device & auto hibernates them. By hibernating it completely stops all the background running services.

Extreme Stability mode is the most efficient way to manage Speed & Battery simultaneously. It automatically increases speed whenever your device demands performance and it saves battery whenever your device is free or in standby mode. Thus it increases your device standby time.

You can also Hibernate, Boost, Kill or Restart apps manually by selecting apps of your choice(Find these features in the Home Screen).

For Automatic Boosting you can only choose one Boost Mode at a time. You can either choose Speed Boost, Battery Boost or Stability Boost. User have to decide that which Boost mode is best for them. Just Activate it & Forget it, you will start noticing the difference. You can also verify the boosting effect by testing the benchmark Score from AnTuTu.

Questions & Answers

Q: What is an APK File?

A: Just like Windows (PC) systems use an .exe file for installing software, Android does the same. An APK file is the file format used for installing software on the Android operating system.

Q: If I install an APK from this website, will I be able to update the app from the Play Store?

A: Yes, absolutely. The Play Store installs APKs it downloads from Google's servers, and sideloading from a site like goes through a very similar process, except you're the one performing the downloading and initiating the installation (sideloading).
As soon as the Play Store finds a version of the app newer than the one you've sideloaded, it will commence an update.

Q: Why can guarantee APK 100% safe?

A: Whenever someone wants to download an APK file from, we'll check the corresponding APK file on Google Play and allow user download it directly (of course, we'll cache it on our server). If the APK file does not exist on Google Play, we'll search it in our cache.

Q: What are Android App permissions?

A: Apps require access to certain systems within your device. When you install an application, you are notified of all of the permissions required to run that application.
