Root Booster, the application on Google Play, was developed by Dominik Nožka.


What it does is essentially test your RAM before setting up proper VM (Virtual Machine) heap size.


What’s VM Heap Size?


VM Heap size is the amount of RAM that can be allocated.


Let’s think about this: On a clean system, how many browser tabs can there be active in parallel (the full experience, to a specified URL) before the browser crashes? Some sites will require more memory and some less.


Since Android executes/runs multiple process requests simultaneously, it must reserve memory for other applications to run as well.


Side Comment: Don’t get me started on the iPhone and its horrible memory management!


By this rule, it means that obviously no single app can use up your device’s entire available memory, therefore, it must be divided.


For such reason, Android, on the development side, has a hard limit per application heap size. If a single application needs more memory and you’ve exceeded the heap size limit, the system will likely force quit the app or the user might get a “out of memory” error.


Balancing the scales, Root Booster is able to modify the virtual memory heap size so each application uses an appropriate amount of VM heap. (Sometimes, Stock ROMs do not do this right by default).


This can speed up your device quite noticeably, especially if your device’s stock ROM setup isn’t the best. On the flip side, it can also slow down your device if not properly configured, and if you’re using graphic/processor-intensive apps like games, or you know, Facebook because that app is unreasonably a resource hogger. (Who uses Facebook anymore, anyway? Are we in the Stone Age?).


Simple, yes?

Anyway, here’s more:



Root Booster Can Modify Performance

CPU Control.

What’s CPU? A processor is essentially the brain of your device. The higher amount of GHz (gigahertz) in the processor, the better it can perform your device’s tasks. It’s essentially an engine that finds a way to work with and make use of all the resources it has.


CPU Control (Governor): A governor is a driver for the regulation of CPU frequency. The CPU Governor decides how fast and when maximum or minimal CPU frequency can be achieved.


Setting an appropriate governor makes your device better in the following categories:

Battery-saving.


Stability & Speed enhancements.


So, does Root Booster actually work?


No such a question can be answered in this world.


It’s a per-device scenario here.


It really depends on how your stock ROM is set up by default, and how it can be manipulated.


For me, Root Booster does make a noticeable difference. I often prefer to use the Speed profile, because that’s what I care most about. Simple apps such as I use don’t require much “stability” because what loads is not graphic or performance-intensive.


Should you give it a try?


I would say yes, especially if you’re working with limited resources/specs. But if you’re on an expensive flagship, it won’t do much for you because oftentimes they already have decent builds and configurations. It can improve something nevertheless, but I haven’t used it on many devices, so I can’t say. On any device I’ve used, expensive or not, it did make some difference.
