Android Cleaner apps can do more Harm than Good

Google’s Android has for long been the most used mobile operating system. Since it’s distributed free of charge, we find it in a wide variety of devices, from entry-level budget phones to $1000 flagship devices featuring the latest innovations and high speed. Unlike iOS that’s only in iPhones and iPads, there are thousands of devices running Android. And for every device, it needs to be separately optimized. Often the optimization is improper, resulting in very slow work. So, phone owners resort to Android cleaner apps that clear cache and all other temporary data freeing memory.

How Android allocates free memory?

Physical memory, called Random Access Memory (RAM) is in charge of storing temporary files during a session. Once the user switches off his PC or smartphone, all data disappear. When a Windows PC encounters filled RAM, it stores excess data on an available hard drive, making the computer very slow. Android handles RAM in a different manner to Windows. It has an inbuilt RAM allocator which already has all capabilities of an “Android cleaner” app. This renders aftermarket Android cleaner apps effectively useless.

What makes Android phones slow?

Early versions of Android often struggled with optimization. In most cases, it wasn’t the fault of the system, it’s about bloatware – apps and user interface codes added by device manufacturers to the basic, “stock” version of Android. This additional software was often a feature of the cheapest phones that had too little hardware resources to handle all that. To avoid this situation, you need to carefully choose manufacturers and models.

Also, mobile devices become slow over time, as we fill its storage with more apps and files like photos and music. This is why you need to once in a year back up all important files and reinstall Android.

How Are Android cleaner apps bad?

Android allocates RAM in a manner that makes the best and optimal use of it at any time. As you work with your device, it stores temp files for quick access in RAM, just like any other computer. But at the same time, it cleans older and less important files, freeing up more space. It is ideal to have the RAM of your Android devices mostly full, so you can have many files on hand for quick access. When it’s near-full, the device works at peak speed. The processor takes files quickly instead of browsing the storage memory.

But when you click the cleaner, it will delete many useful files. While you are unaware of how cleaning software selects files for deletion, Android’s inbuilt RAM allocator uses artificial intelligence to “learn” your device use habits. Aftermarket cleaners are always behind it. They just use few criteria for removal, such as how old or how big the file is.

Owing to that, the phone will often struggle to find missing files. It will require fetching and processing these files anew. That would use a lot of excess memory, processing power, and other resources.


If your Android phone is slow, you may consider these steps:

  • Clean unused apps – it is primarily useful for budget phones.
  • Clean unused files from storage – since full storage hits performance more than a full RAM module.
  • Reinstall your phone’s Android. The operation (“hard reset”) is quite easy.
