Short answer: clean up Telegram storage on iPhone by clearing cached media and old downloads inside Telegram first, then reviewing the images and videos that were already saved to Photos. If you only clear cache, the iPhone can still stay full because the library clutter remains.
Telegram tends to hide storage in a few places at once: cached media, downloaded files, channel videos, and saved images that outlive the original conversation. That is why a useful Telegram cleanup needs to separate temporary app storage from the permanent media that ended up in the photo library.
What to do first
Check Telegram storage usage and clear the largest caches and stale downloads first.
Review large channel videos and old received files before smaller items.
Keep current working files if the problem is old buildup rather than active conversations.
After the app cleanup, move into Photos to review saved images, videos, and screenshots.
Why Telegram cleanup often spills into Photos
Downloaded memes, channel screenshots, saved clips, and reference images often stop behaving like “Telegram files” and turn into normal photo-library clutter. Once that happens, the cleanup job belongs to the camera roll, not to Telegram settings alone.
Where Cleanor helps after Telegram cleanup
After cache and downloads are reduced, the remaining clutter is usually repetitive media. Cleanor for iPhone is the stronger route for reviewing saved screenshots, similar images, and heavy videos when the problem has already moved into Photos.
What people usually ask next
Does clearing Telegram cache delete my important chats? Not necessarily. The goal is usually to remove temporary media weight first, not destroy active conversations.
Why does Telegram keep using space again? Because new media keeps being cached and more files get saved into the library over time.
What should I clean after Telegram? Screenshots, heavy videos, and repeated images are usually the next low-friction wins.
If the clutter is mostly screenshots, continue to Screenshots cleanup. If the bigger issue is the whole phone feeling full, open How to free up iPhone space.
Telegram storage is rarely just one cache problem. It usually becomes a broader iPhone media-cleanup problem over time.
