If your cell phone keeps notifying you that the Storage is full., If your device freezes when recording a video or won't let you install anything, there are several solutions that can be fixed without replacing it. apps to free up space on your cell phone They find what's taking up memory and help you delete only what you don't need.
Over time, devices accumulate app cache, temporary files, videos received on WhatsApp, old screenshots, and duplicate photo copies. In this article, you will learn about the best options available in... Play Store, to understand how each one really works and — equally important — to know what this type of app is. no You can do it. That way you choose with the right expectations and don't waste time on exaggerated promises.
Why does my phone fill up so quickly?
It's common to see people complaining that their internal memory is always full even without having installed many applications. This happens because, in addition to the files you download, the system and the apps themselves generate data. temporary files and cache — local copies of images, videos, and pages that the app saves to open faster the next time.
Add to that the videos received in group chats, the repeated photos from when you took the same scene five times, and the screenshots that nobody deletes. One cleaning app It helps because it brings everything together on a single screen, separated by category and size, instead of you having to hunt through folder by folder in the file manager.
What a cleaning app does — and what it doesn't do.
Before we get to the list, it's worth managing expectations, because advertising for this type of app often promises more than the technology delivers.
What it actually does: It finds cache and residual files, shows which folders and apps are taking up the most space, lists duplicate or very similar photos, points out forgotten videos and large files, and makes it easy to batch uninstall apps you haven't opened in months. On a device with limited storage, this usually yields anywhere from a few megabytes to several gigabytes back — and a phone with free space really does perform better, because the system needs leeway to save temporary files.
What he doesn't do: no app increases The RAM or physical storage of the device—the hardware is what it is. There's also no app that transforms an old phone into a top-of-the-line model: if the processor and RAM are already outdated, cleaning frees up space, but doesn't change raw performance. And the famous "speed up" button that closes background apps has a limited effect on modern Android, because the system itself manages RAM and reopens these apps soon after—sometimes using more battery in the process. Use these apps for what they do well: Find and remove what is taking up space..
The 5 best apps to free up more space on your cell phone
All the applications below were checked in Brazilian Google Play Store. The ratings and download counts are those that appeared in the store on the date of this update and may change over time.
CCleaner - Cell Phone Cleaner
AndroidO CCleaner It's the best-known name in the category, inherited from the computer cleaning program. On Android, it scans and organizes the results into blocks: app cache, residual files, old downloads, similar photos, and rarely used apps.
The strong point is the storage analyzer, This shows, in order of size, what is occupying the disk space. From there, you decide what to delete—the app doesn't remove anything without your confirmation. It also displays system information, such as processor usage and temperature, but consider this as monitoring, not as something that will speed up the device.
The download is free and ad-supported, with an optional subscription that unlocks automatic cleaning and removes ads. It's worth noting that CCleaner... It's not exclusive to Android.There is also iPhone version on the Brazilian App Store, focused on organizing photos and contacts. The button above takes you to the app's page on the Play Store.
Files by Google
AndroidIf you want a smooth experience, without ads and without in-app purchases, the Files by Google (formerly Files by Google) is the safest choice. It's both a file manager and a cleaning tool, and it comes pre-installed on most Android phones.
In the “Clean” tab, the app suggests specific actions: deleting temporary files, removing memes and downloaded images from conversations, deleting large videos, emptying the trash, and uninstalling unused apps. Each suggestion comes with the exact size you will recover, and nothing is deleted without you tapping to confirm.
Another useful detail: Files has own trash can, This app saves your deleted files for 30 days. In other words, if you accidentally delete something during a cleanup, you can still undo it. It's the app we recommend for those who want to solve the problem without installing anything heavy.
Avast Cleanup – Cleaning app
AndroidAvast is best known for its antivirus software, but... Avast Cleanup It's a complete cleaner with one of the best ratings in its category on the Brazilian Play Store. It detects obsolete data, residual files from uninstalled apps, and duplicate media.
One feature that usually frees up a lot of space is the photo optimizationThe app recompresses images from your gallery to take up less space. Be aware, however — recompression is a lossy process: the photo will be smaller in megabytes and, depending on the level chosen, slightly less detailed. Therefore, the app offers to save the original version to the cloud before replacing it. If the image is irreplaceable, it's better to back it up instead of recompressing it.
There's also app hibernation, which suspends apps you've chosen to reduce background activity — the actual effect varies considerably depending on the device manufacturer and Android version. Like CCleaner, Avast Cleanup... There is also an iPhone version., available in the Brazilian App Store. The free version displays ads and reserves some features for subscriptions.
AVG Cleaner - Cleaning App
AndroidO AVG Cleaner It comes from the same company as Avast and delivers a very similar experience, albeit with a different visual identity. It organizes the cleanup using suggestion cards and is good at finding things that go unnoticed: old files in the downloads folder, duplicate message audios and videos.
O photo analyzer It groups similar images and suggests keeping the best one from each sequence — useful for those who have thousands of photos. You can also schedule a periodic check, so you don't let your storage reach its limit again.
It's free to download, with ads and an optional paid version. If you already use Avast Cleanup, there's no reason to install both: choose one. AVG made this list in place of Droid Optimizer, which... It's no longer available on the Brazilian Play Store. and that's why it's no longer recommended here.
Nox Cleaner
AndroidO Nox Cleaner It concludes the list as a lightweight alternative for those who want something straightforward. The interface is colorful and the flow is simple: scan, review what was found, and delete. It covers cache, residual files, similar photos, and large files.
The app also includes a security checker and a "turbo mode" for games. Regarding the latter, keep your feet on the ground: what it does is suspend notifications and selected apps while the game is running. This can reduce interruptions, but It does not increase RAM or processor performance..
Nox Cleaner has the lowest rating on this list in the Brazilian Play Store (3.9), so treat it as a secondary option: if Google Files or CCleaner already solve your problem, there's no need to install another cleaner.
You can free up space without installing anything.
Before downloading anything, it's worth trying the native method — in many cases, it solves the problem. On Android, open Settings > Storage (On some devices, "Device Care"): the system shows how much space each category occupies and offers the cleaning suggested by the manufacturer.
Other actions that tend to generate a lot of space:
- Empty the gallery trash can — In Google Photos and in the galleries of various manufacturers, what you deleted continues to occupy space for up to 30 or 60 days.
- Clear WhatsApp storage — In Settings > Storage and data > Manage storage, the app lists conversations and files larger than 5 MB.
- Send the photos to the cloud. and use the "Free up space" option in Google Photos, which removes only the images from your device that already have a saved copy.
- Review apps by size And uninstall the ones you haven't opened in months — often a single game takes up several gigabytes.
Extra features that make a difference
In addition to deleting what is no longer needed, several of these apps to free up more space on your cell phone They include features that help in everyday life. Some have a recommendation system, indicating what can be safely removed and what is best kept — which prevents accidentally deleting something important.
Others offer notification management, security verification, and the ability to... schedule periodic cleanings, ...so your phone doesn't fill up again without you realizing it. There are also those that integrate with Google Drive or Dropbox, allowing you to move files to the cloud instead of simply deleting them.
Two practical recommendations: install only one When choosing a cleaning app (two running together compete for space and battery without benefit), check the permissions requested. A cleaner needs access to files and the use of applications—if it asks for much more than that, be suspicious.
Does it work the same way on the iPhone?
No. iOS doesn't allow third-party apps to clear the cache of other apps, so no iPhone cleaner performs the same type of cleanup as Android apps. What exists in the App Store are tools focused on... duplicate photos and contacts That is the role of the iOS versions of CCleaner and Avast Cleanup mentioned above.
On the iPhone, the path that frees up the most space is the native one: Settings > General > iPhone Storage. There, the system lists apps by size, suggests downloading those you don't use (while keeping the data), and shows how much space videos and conversations are taking up. Don't forget to empty the "Recently Deleted" album in Photos, which retains images for 30 days.
