How can I speed up my android phone?

Free up space and RAM

First of all, you backup all your documents, photos, and videos then Delete it. Because space on your phone and RAM is the main reason for your phone slow down.

You can save your smartphone from slowing down by removing unnecessary data. A breathing room is required for any phone to run smoothly, and if this storage is full, the automatic may start to slow down.

The good thing is that many Android devices offer options to clean storage without installing third-party apps.

Remove apps that you never use, which may free up your storage and operating system.

Whether you are using one app after another or multi-tasking, which makes it easy to switch between different apps, these unused apps keep running in the background. By clearing background apps, you can make the phone run faster.

 If you have enabled the developer option then you can also stop apps or services running in the background.

Install selective applications

You get a new smartphone, after that you start installing apps from the Play Store one by one, which you don’t use or rarely do, you also install them. As a result, your store affects your CPU which is the main reason for slowing down your phone.

Only install selected apps that you use the most. You can uninstall after using apps that you use very rarely or occasionally.

Battery heating

Another reason for the device to slow down is that the battery on your Android device overheats as it reacts to the current flow. In this condition, your battery starts heating up quickly. Because heat causes thermal throttling, due to which the CPU is not able to perform its best. The CPU provides limited performance in hot conditions which protects your phone from further damage.

Reboot your device

A simple and quick solution for a slow phone is to simply restart it. This clears the cache, and it prevents unnecessary tasks from running, making the device faster.

Just hold down your phone’s power button, and tap on the restart option, and then tap OK to confirm.

Uninstall cleaner and task killer apps

Cleaner apps and third-party storage management apps can usually be more harmful than good. Android phones manage their RAM to the best of their ability.

If you kill the background application you need, it takes longer to reboot and use more battery which can slow down your device.

If you use an app like Clean Master then you should know that these apps often clear the way for app caches that slow down your operation rather than speed it up.

Even though the speed of these cleaner apps shown on your home screen has increased, nothing really happens. When using third-party applications such as Cleaner you should be concerned about your privacy and the security of your phone.
