Root Booster is for root users who need more performance to run apps smoothly without lag or for those who need to improve battery life.

There are many applications that can save battery or boost performance. However, Root Booster uses the most tested settings for the best results. You can easily apply these settings with preset modes that are guaranteed to boost speed, boost battery, or boost stability. You can accomplish these modes by administering suitable settings to the main parts of the phone. Here are some explanations of what Root Booster does to the CPU, RAM, and Android OS in particular.

Hibernation (Android OS Optimizer)

Each Android app can have one or more services. They run in the background and usually perform some kind of activity. Many people think that when they delete an app, it completely stops draining battery and computing power, but that’s not true. The app still has services running after the kill and continues to consume battery and computing power. On the other hand, if you hibernate an application, it stops its services and the application no longer consumes the battery and processing power of the CPU. Hibernation is a gentle and efficient way to save battery life and boost performance. Root Booster will find apps that drain the battery and require performance and hibernate them automatically.

CPU (processor regulator control)

A governor is a controller for adjusting the CPU frequency. The governor concludes how quick and when the greatest or least computer processor recurrence will be reached. Setting the appropriate regulator allows your device to save more battery, faster or even more stable. However, deciding which governor is right for you is a little tricky.
Root Booster can decide which regulator to use and automatically applies the most suitable regulator for the selected mode. RAM (memory manager)
Each app uses the virtual machine heap for data and work. The main reason for changing the virtual machine heap size is to improve stability. Many large applications require a large amount of memory (VM heap) for their work. If the virtual machine heap size is less than the required memory, an application crash (out-of-memory error) occurs. Setting the heap size is a difficult task and there is no manual to configure it for the best performance. The root booster will test your RAM and set the heap size of your VM for better stability and performance.

Editor's Review

For the battery I’m still unsure, that is debatable. Using the free version. This app did however speed the phone up to a very noticeable difference. Since I’ve cleared my cache out before by using the power button and volume key it seems to have done this within the app. Will be monitoring my battery drainage since it’s a new battery as well on the phone but it certainly speed the phone up and Google is way much faster. Still thinking it cleared the cache in which no app is needed for that.
