About this app

Root booster is for root users who need more performance to run applications smoothly without lags or for those who need to improve a poor battery life

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.

Hibernation (Android OS optimizer)
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.
Root Booster will find battery draining and performance demanding applications and auto hibernates them.

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.

New version for non-rooted users

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.

Notable speed up, but configuration is too opaque. I've had issues with my mileage tracker app (among others). For this to be useful, you really need to be able to whitelist background services, since some of them are vital to what one uses their phone for. If that were a pro option, I'd be happy. Unfortunately, this app isn't too useful for me as it is now.

Seems to make a noticeable difference on an older device (ICS) when set to speed option without creating instabilities. 4 instead of 5 stars only because there is just so much you can accomplish with old hardware- not a reflection of the program itself. Once set to speed, the device retains the settings between boots with no further action. Probably rates 5 stars as an app.

I have a 4 gigs of RAM of memory with a 32 gig internal Hard drive on a LG G6 that I'm testing this on. It seems to be working no differently than the unpaid version in my opinion. SD Maid & SD Maid Pro in the play store do about the same thing however I paid more for this than their premium version. Plus their app gives you more insight to what is really in your device. I was kinda hoping the same thing here but was disappointed. If you're going to charge to clean emulated data then you need to make sure when it does clean emulated data it doesn't clean your installed Games, bc no one likes re-downloading game data every time. This will increase your data usage, data amount, and wasteful time spent waiting uploading it again. Over all, out of 5 for this app I give it a 2.5 for the basis boring in-app design. I'll give it a 3 for an overall, overpaid, premium device booster as I really don't see a difference in it being better or not.
