If your phone has been warning you for a while that You run out of storage and everything runs slower than usual.It's quite likely that the prime suspects are WhatsApp and Telegram. They're the apps we use most often on a daily basis; we send and receive photos, videos, voice notes, documents, memes galore… and all of that gradually accumulates until it takes up several gigabytes without you even realizing it.
The good thing is that, with a little calm, you can Perform a deep clean of WhatsApp and Telegram and recover a good amount of gigabytes Without losing important messages or your key files. Let's see how to do it step by step, with specific tips and clear explanations, and we'll finish with a general Android tune-up to get your phone running smoothly again.
Why do WhatsApp and Telegram take up so much space on your phone?
With daily use, the mobile phone accumulates a huge amount of temporary files, cache, photos, videos, and residual data that you don't see anywhere, but that are there taking up space. Every photo sent to the group, every joke video, every endless audio message, and every document is saved in one way or another.
In the case of Telegram, the philosophy is different from that of WhatsApp: virtually all content is stored in the Telegram cloud And on your phone, you only store a temporary copy (cache) of the photos, videos, and files you've opened. This cache grows over time, but the good thing is that you can delete it without losing anything because the original remains on Telegram's servers.
WhatsApp, on the other hand, It depends much more on the device's internal storage.By default, it downloads and saves almost everything you receive, both within the app itself and in internal folders (and often in the gallery as well). Add to that the local and cloud backups, which grow larger the longer you use the app.
Between automatic downloads, generous caches, tons of multimedia, and old backups, It's not surprising that WhatsApp and Telegram end up being the apps that take up the most gigabytes on a mobile phone.especially if it's 64 or 128 GB and you're involved in many very active groups or channels.
Before the cleanup: backup and updates
Before you start deleting things willy-nilly, it's important Protect what you really don't want to lose with a good backupSo, if you accidentally delete the wrong chat or an important file, you'll have time to recover it.
Ideally, you should store it outside of your phone. your important photos, videos you want to keep, sensitive documents, and contactsWhether it's on Google Drive, iCloud, OneDrive, a computer, or an external drive. And while you're at it, make sure that Android, WhatsApp, and Telegram are up to date to their latest versions, because they usually include performance improvements and in storage management.
On most Android phones, you can check for new system versions by going to Settings > Software update (or similar) and tapping on the option to check for updates. Then, open Google Play, go to your profile and Update pending appsespecially WhatsApp, Telegram, and tools like Google Files.
How to see what WhatsApp and Telegram are actually using.
Before you start deleting, it's a good idea to take a look at your phone's storage panel to Confirm how many gigabytes each app is actually using.This way you'll see if the problem lies mainly with messaging or if there are other equally data-intensive apps.
On Android, the normal thing to do is to enter Settings > Storage or MemoryThere you'll see a bar with the total storage space and a breakdown by category: apps, photos, videos, system cache, miscellaneous files, etc. If you go into the details of the apps, you can see which ones are taking up the most space.
If on that list WhatsApp appears in first position or very high up, and Telegram is not far behind either.You now have confirmation that you need to get serious about cleaning within those two applications.
Deep cleaning of WhatsApp: step by step
WhatsApp is usually the one that causes the most problems with memory because it comes configured from the factory to download and save virtually all the content you receiveThe trick lies in two things: cleaning up what has already accumulated and, above all, changing the settings so that it doesn't happen again so quickly.
Disable or limit automatic file downloads
The first step to stop WhatsApp from devouring storage is Stop the automatic download of photos, videos, audio, and documentsIf you save everything without asking, it's only a matter of time before your memory explodes with memes and videos you only watch once.
On Android, you can adjust this like this (the names may vary slightly depending on the version):
- Open WhatsApp and enter Settings (usually from the three points in the upper right corner).
- Press on Storage and data.
- Inside, go to Automatic file download.
- Adjust what is downloaded using mobile data, Wi-Fi, and while roaming. unmarking photos, audio, videos and documents in the options that don't interest you.
From that point on, the content will stop downloading on its own and only what is saved will be saved. You decide to download by clicking on the fileIt's a very effective way to prevent your gallery from filling up with things you don't even remember.
Use “Manage storage” to locate the largest files.
WhatsApp includes a very useful tool that many people don't even use: the section Manage storage, where you can see at a glance what's taking up the most space, both by file type and by chat.
To get there, in recent versions of the app, go to:
- Settings > Storage & data > Manage storage.
A summary will appear on that screen with the space used by WhatsApp, large files (e.g., more than 5 MB), and chats sorted by sizeIt's ideal for capturing large videos, very long audio files, and documents you no longer need.
You just have to go into each section, select the items you want to delete and tap the trash can icon. You can select many at once, so with just a few minutes of reviewing, you can free up several gigabytes.
Empty or delete groups and chats you no longer use
Another common source of problems are the Old groups and conversations that are still there but no longer contribute anythingGroups from school, your old job, a past event, etc. Even if you don't open them, everything that was sent there still takes up space.
From the chat list, you can press and hold a conversation to empty it or delete it:
- empty chat Delete all messages and files within, but leave the chat in the list in case you want to continue using it.
- Delete chat Remove all conversation from your home screen (including messages and multimedia).
Additionally, in “Manage storage” you will see Chats sorted by the space they occupyThis allows you to go straight for the heaviest groups and empty them out first.
Check your WhatsApp gallery and folders
When you delete media files using WhatsApp's internal tools, Those items also disappear from the mobile gallery if they were synced.So you're already doing a good part of the work. Even so, it doesn't hurt to check manually.
Open your Photos or Gallery app and search for albums like “WhatsApp Images”, “WhatsApp Video” or similarWithin them you can delete duplicate memes, pointless screenshots, or videos you know you'll never watch again.
Very important: then enter the empty the trash can in your gallery or Google Photos app.Until you completely empty it, the files continue to occupy practically the same space even though in theory they are "deleted".
Clean up WhatsApp's internal folders with a file manager
If you want to further refine the cleaning process on Android, you can delve into the internal folders where WhatsApp stores all its contentIt's best to be careful here, but used wisely it's a very powerful way to remove remnants and duplicates that the app itself no longer shows you.
- Open the app Archives and enters the internal storage Of the device.
- Go to the folder Android > Media.
- Inside locate com.whatsapp > WhatsApp.
- Sign in Media, where you will see subfolders for images, videos, audios, documents, etc.
Within each type (Images, Video, Audio…) you will find a folder SentThese are copies of everything you've sent. Often, these duplicates are unnecessary because you already have the original file saved elsewhere. Deleting the contents of those Sent folders usually frees up a lot of space without losing access to anything essential.
The main WhatsApp folder may also contain directories such as Backups and Databaseswhich contain local backups. If you've already set up backups in Google Drive and don't need to keep ten old versions saved, you can Remove the oldest ones and leave only the most recent one. to avoid wasting gigabytes.
How to prevent Telegram from filling up memory with cache
Although Telegram performs better than WhatsApp in this regard because All the "serious" content actually lives on their serversYour local cache can grow quite a bit if you follow many news channels, meme groups, or active chats.
The advantage is that Telegram offers very comprehensive internal tools for controlling that cache, both to delete it all at once and to limit how much space it can occupy and for how long the files are stored on the device.
What exactly is the Telegram cache and why can it be safely cleared?
The cache is nothing more than a set of temporary files that apps save on your mobile phone To load faster: thumbnails, local copies of photos and videos, frequently accessed data, etc. In Telegram, virtually all the media you open is copied to that cache.
With daily use, that cache can end up taking up several gigabytes, but the important thing here is that The application saves the originals in the cloud.In other words, what you have on your phone is a temporary duplicate that can be deleted without losing anything, as long as you have an internet connection to download what you want to see later.
Therefore, even though Telegram's cache can take up a lot of memory, The app itself doesn't usually take up as much space as other messaging platforms.A large part of the trick is precisely that almost everything important is on their servers, not on your device.
How to clear Telegram's cache from within the app
Rather than going into Android settings and deleting data as if there were no tomorrow, the recommended approach is Use the cache manager that comes standard with Telegram.It's very clear; it tells you how much space each type of file takes up and lets you choose what you want to clean.
On Android, the standard path is usually:
- Open Telegram and go to Settings (via the side menu or by tapping on your profile picture).
- Press on Data and storage.
- Inside, tap on Storage usage.
- You'll see a button like this. “Clear Telegram cache” or “Clear cache”.
Pressing it will display a breakdown with How much space is used by the cache in total, and how much corresponds to photos, videos, files, and other data?You can check or uncheck what you want to delete before confirming.
The key thing here is that You're only deleting the copy stored on your mobile phonePhotos, videos, and documents will continue to appear in chats and channels, and when you open them again, they will be downloaded again from Telegram's servers.
Limit the maximum cache size and the time files are stored
In addition to cleaning, Telegram lets you configure how large the cache can be and how long files will be kept on your phone before being automatically deleted. It's the most convenient way to prevent the app from taking up several gigabytes again without you noticing.
In the same "Storage Usage" section you will find options for:
- Adjust the maximum cache sizewith values like 5 GB, 16 GB, 32 GB, or even unlimited. If your phone is running low on memory, it's advisable to set a low limit, for example 5 GB limit.
- Choosing How long are downloaded photos and videos stored? before being automatically deleted: 1 day, 1 week, 1 month or never.
These options usually apply separate from private chats, groups, channels, and storiesThis allows you to be more aggressive with news or meme channels and somewhat more flexible with personal or work conversations where you want to have certain files on hand.
For example, you can configure Telegram to Only keep the files for one week and never let the cache exceed 5 GBSo, even if you use the app a lot, the space it consumes will never get out of control.
Delete chats, channels, and bots that no longer serve you.
Although Telegram stores everything in its cloud, the chats, groups, channels, and bots you no longer use They continue to generate some cache each time you open them or new messages are loaded.
It's worth taking a look at your list of conversations and Leave channels and groups you no longer read, and delete old chats you don't need to keep.It's typical to have groups from a course, a specific event, or bots that you tried once and then just stayed there.
When you delete an entire chat in Telegram, All local copies of your photos, videos, and files will also disappear.So you free up space and also make the list much more organized, without so much visual clutter.
General Android cleanup: beyond messaging apps
Once you've made WhatsApp and Telegram much lighter, it's the perfect time to perform a general cleaning of the rest of the systemMany mobile phones hide several gigabytes of data among forgotten apps, old downloads, huge caches, and offline content you no longer use.
Uninstall apps you don't use and disable bloatware
Over time, we install apps "just in case" that we then never open again. Those apps They take up space, they update, they consume some battery, and sometimes they run background processes. without contributing anything to your life.
Go to Settings> Applications And review the list at your leisure. If you see an app you haven't opened in months, you can probably live perfectly well without it. Press and hold the icon or go to its details page and tap on Uninstall apps (or “Archive app” if your mobile device offers this option).
In addition, many phones come with bloatware or pre-installed applications which can't always be completely deleted. In those cases, at least you can use the option to Disable or Turn Off so that they stop being updated and take up the least amount of space possible.
Clean up unnecessary photos, videos, and folders
The camera on current mobile phones generates Photos and videos are getting larger and larger, especially if you record in high resolution.It's a good idea to occasionally do a clean-up in the gallery to remove bursts, blurry photos, useless captures, and videos you're not interested in.
If you use Google Photos or another cloud service, first make sure that Everything you want to keep has been uploaded correctlyThen you can more easily delete what you don't need. In Google Photos, for example, you can go into the folder of Camera and do selective cleaning.
Don't forget to check the folders generated by other applications like WhatsApp, Telegram, Instagram, or your browser. Many create specific albums within "Photos on device." From the Albums tab (or similar), you can access each folder and delete what's left over or delete the entire album if you don't have anything you want to keep.
Empty the trash bin in your gallery and Google Photos
In almost all gallery apps and in Google Photos, when you delete something It is not completely eliminated immediatelyInstead, it goes to a bin where it stays for a few weeks in case you change your mind.
If you're looking to gain space now, it's time to go into that trash can and empty it manuallyUntil you do that, the files will continue to take up space on your internal storage even if you don't see them in the main library.
Removes old downloads, junk files, and duplicates
The Downloads folder is another classic: PDFs that were sent to you years ago, ZIP and RAR files that are no longer useful, old installers, temporary documents…All of that just sits there forgotten unless you go in specifically to clean it.
Using your mobile's file manager or the app Google filesOpen the Downloads section and delete anything you know you no longer need. Google Files also has a tab called "Clean" where the app itself analyzes the storage and suggests you delete it. junk files, temporary files, and duplicate files quite safely.
That same section usually includes recommendations for apps you rarely use, large files, and items downloaded a long time agoWith just a couple of taps, you can select what you want to remove and instantly see how much space you're recovering.
Control the cache of other resource-intensive apps (social networks, browsers, etc.)
Applications like Instagram, TikTok, Facebook, Chrome, or some browsers They can accumulate a lot of cache over time. This is temporary data that helps everything run faster, but it regenerates itself and can be cleared when storage is tight.
If you see that any of these apps are taking up a huge amount of space, go to Settings> ApplicationsSelect the problematic app, go to Storage and click on Clear cacheYou will not lose your account or your basic history, only that temporary data will be deleted.
Yes, There's no need to obsess and clear the cache every two daysIt's a useful measure when you're really running low on space or when an app is behaving strangely, but if you do it constantly, many apps will fill up the cache again just as quickly.
Check out offline content from YouTube, Netflix, Spotify, and similar services.
Video and music platforms that allow offline downloads They can swallow several gigabytes in a very short timeEntire playlists, complete series, or piles of videos saved to watch on the subway remain there even if you never watch them again.
On YouTube, go to your tab for Downloads To see what videos you have saved on your device, delete the ones you no longer want. In Netflix, Prime Video, or similar apps, look for the section of Downloaded content or “Downloads” and clear watched seasons or movies you’ve already finished.
On Spotify, check your playlists and downloaded albumsIf you have albums you haven't listened to in months, you can remove the download and still have them available for streaming, but without them taking up local space.
When is it worth considering a factory reset?
If after doing all this cleaning (WhatsApp, Telegram, photos, downloads, various caches…) you notice that the phone It's still just as slow, with strange errors or constant crashes.Perhaps the problem isn't just a lack of storage space. The system might be overloaded after years of use.
In those extreme cases, it makes sense to value a factory data resetThis leaves the phone like it's brand new (albeit with the current version of Android), without your apps or data. It's a drastic measure, but sometimes it's the only way to restore speed to a badly worn-out phone.
Before taking that step, though, make sure you have Complete backups of photos, documents, chats, and anything else that matters to you.Then, you'll usually find the reset option in Settings > System > Recovery options or Reset (according to the manufacturer). Use the settings search by typing "factory reset" or "reset" if you don't find it the first time.
Habits to prevent your phone from filling up so quickly again
Beyond doing a thorough cleaning every so often, there are A few simple habits that greatly help keep storage under control without having to fight with the "insufficient space" warning every month.
For example, you can get used to Check the mobile phone's storage section once a month.Pay particular attention to the size of WhatsApp, Telegram, and video or music apps. If you see any that are excessively large, spend five minutes on it and you're done.
It is also highly recommended disable or limit automatic downloads Not just on WhatsApp and Telegram, but on any app that tends to save everything without asking. You'll gain control and prevent tons of content from piling up that you never even see.
Don't let them drag on forever Groups, channels, and chats that no longer make senseWe often keep them "just in case," but the reality is they only take up space and add clutter. Getting rid of them or archiving them in time saves a lot of memory in the long run.
Lastly, remember Empty the trash bin in your gallery, Google Photos, and other apps from time to time.Avoid installing miracle cleaning apps from dubious sources and keep both your system and apps updated. With that, plus proper cache settings in Telegram and manual downloads in WhatsApp, your phone will stay lightweight for much longer without needing to upgrade just because "there's no more room."
