If you've ever had an older Android phone, you've certainly been introduced to Clean Master - that app that promised to free up space, delete useless files, improve performance and even make your phone faster. But now, in 2025, with the latest systems, many people are still wondering: Is Clean Master worth using? Or has it become a thing of the past?
The answer is not so simple. It has advantages, it has risks and there are still a lot of people using it. So let's take a look at the whole picture so you can make an informed decision as to whether the app is on or off your phone.
What is Clean Master and what is it for?
Clean Master is an optimization application created by the company Cheetah Mobile, which has become very popular for offering a combo of junk file cleaning, RAM freeing, antivirus and battery saving - all in one place.
It became one of the most downloaded apps in the world in its golden age, mainly because it took up little space and promised to solve the typical crashes of Android phones with little memory.
Will it still work in 2025?
It works, it works. But with a few caveats. The Clean Master is no longer available in the Play StoreGoogle has banned Cheetah Mobile for suspicious privacy practices and manipulating ad clicks. In other words, if you want to install it today, you'll have to resort to APKs from outside the official store - which is already a warning sign.
What's more, Android systems themselves have evolved considerably. Today, many phones already have built-in tools that clean the cache, limit background processes and optimize performance natively.
What are the advantages of Clean Master?
If, despite all this, you're still considering using the app, it's worth remembering the positive points that have made it so popular:
1# Cleaning up temporary filesIt detects and deletes application caches that you didn't even know were accumulating.
2# Simple and intuitive interfaceEven those who don't know anything about technology can use the app with ease.
3# Freeing up RAM memory: closes background processes that are eating up system resources.
4# Application managerThe app manager: allows you to uninstall apps you no longer use and manage permissions quickly.
5# Cooling functionThe new feature : analyzes the apps that are straining the processor and helps to reduce the phone's heat.
In other words: if installed correctly, Clean Master can still be useful, especially on older phones or those without robust native tools.
What are the risks of using Clean Master in 2025?
Now comes the B side of the story - and it's a heavy one. Clean Master has been banned from the Play Store for serious reasons, such as:
- Excessive collection of personal data
- Display ads disguised as features
- Manipulation of advertising clicks
- Invasive permissions that didn't match the app's function
In addition, downloading APKs from outside the official store can open loopholes in the system. Many sites offer modified versions with viruses or malware embedded. If you don't have a good understanding of digital security, it's very easy to fall into a trap.
Does Android still need this kind of app?
This is an important question. In 2025, Android has more and more intelligent features. Models like the Samsung Galaxy, Xiaomi, Motorola and others already come with them:
- Automatic cache cleaning
- Battery optimization by AI
- Monitoring memory usage and apps in the background
- Advanced energy saving mode
In other words: on newer devices, Clean Master becomes almost unnecessary. Instead of helping, it can even overload the system with duplicate or poorly optimized functions.
Do you have better and safer alternatives?
If you miss a cleaning app and want something more reliable, here are some safe options that are still available in the Play Store:
- Files by GoogleClean junk files with one click and help organize photos, videos and documents.
- SD MaidMore technical, but extremely effective for those who know a little more about the system.
- AVG CleanerThe best of the best : combines cleanliness and performance optimization, with a modern look.
- CCleanerfamous on PC, it also has an Android version with good cleaning functions.
These apps follow Google Play guidelines and have constant updates - which already guarantees more security.
When can Clean Master be useful?
If you have a old cell phoneIf you're running Android 7, 8 or even lower, and you don't have any native cleaning tools, Clean Master can be used as a "workaround". But it's essential to take a few precautions:
- Download only from trusted sources (such as APKMirror)
- Don't allow unnecessary access to sensitive data
- Avoid activating notifications and advertisements
- Use only the basic functions (cleaning and RAM)
Even so, the recommendation is to look for safe alternatives. Even on old devices, the security risks end up outweighing the benefits.
Is it worth installing in 2025?
To put it bluntly: not worth it for new cell phones. Today's Android already does what Clean Master promised. And considering that the app has been removed from the Play Store for violating security rules, installing it is not recommended.
Now, if the device is very old, without support, and you know what you're doing, you can use it with a LOT of caution. But it's like riding a bicycle with bad brakes: it only works in emergencies, and with extra caution.
