The third-party Speed-up applications dedicated to the optimization, cleaning and acceleration of the device seem to have gone to the background, since mobile manufacturers have natively implemented programs that fulfill those functions.
However, it is well worth collecting the best Android Speed-up apps for those users who have performance problems on their mobile. As we know, not everyone can afford to change devices every year.
All-In-One Toolbox
This all-in-one allows us to clean the device and optimize it to increase its performance, all through a simple button , without more history.

Nox Cleaner
In addition to its multiple functions, it has a double method to accelerate the device. On the one hand, it optimizes the system to accelerate it, and on the other hand, it cools the CPU so that there is no overheating.

Booster – speed up your phone
With a simple and very clean interface, it offers a widget with which it will not be necessary to enter the app to give that little push to the processor of our mobile.

APUS Security – Remove Virus, Antivirus, Accelerator
Of course, this app does everything in terms of mobile care is concerned, and also fulfills its function of accelerating it up to, as the description reflects, 50% more .

Speed Booster
Another CPU enhancer that has earned a place in this list. In this way, it automates exactly the situations in which you have to intervene to improve performance, and also, with a built-in gaming section .
Speed Booster and clean master
Eliminates unnecessary processes and files that delay the response times of the terminal, with the added function of cooling the processor if its temperature is high.

iClean
The next one in the list eliminates, through an analytical mechanism, all background processes that are unnecessary at various times of the day. In the same way, for those interested, it has a dynamic CPU cooler to prevent overheating.

Finally Clean: Booster, CPU Cooler

Fancy Booster
It may happen that the remedy is worse than the disease, and that these types of applications instead of helping speed, make it worse. This usually happens because these accelerators get to occupy important spaces in the storage of the terminal, something that does not happen with Fancy Booster . It only weighs 10 MB , designed for those phones with less hardware.

Droid Optimizer
Be careful with this app , because it intends to disassemble the mechanism that supports the rest of the accelerators. As they detail, the cooling of the CPU is so complex that it needs root permissions , so everything that is not with root will be to slow down the processor , rather than cool it. Therefore, this app does not perform that function.
Root Booster
This would do for those more advanced functions, such as advanced configuration on the CPU frequency, or we can also choose to have the app automatically manage what the device really needs.
