Telegram Storage Usage Architecture: Zero-Footprint Cloud Caching, Interactive Pie Chart Analytics & Granular Cache Eviction
The storage screen shows what Telegram is using on your device, broken down by type and by conversation. It is the only place that tells you which of your four hundred chats is responsible for six gigabytes.
Reading it takes a minute and almost always contradicts what you assumed. This page is how to read it and what to do with the answer.
What you will be able to do
- check_circle See what the space is actually made of, rather than guessing.
- check_circle Find the individual chats using the most, and clear those alone.
- check_circle Tell what is cache from what is genuinely yours.
- check_circle Put a ceiling on the whole thing so it never needs doing again.
Scrolling past the chart is the useful part — underneath it is the list of chats, sorted by size.

The chart at the top splits the space by type: video, photos, files, other. It answers what kind of thing is filling the phone, and the answer is almost always video.
Below it is a list by conversation, largest first. That answers which chat, and it is the more actionable of the two — you can clear one channel's cache without touching anything else.
Both are cache. Every byte on this screen exists on Telegram's servers as well, and clearing any of it costs you a download the next time you open the thing.
Reading it, in order
Four steps. Doing them in this order means you rarely have to clear everything.

The one-minute version: find the biggest chat, clear that one, set a cache ceiling, leave.
settings Getting there
- Open Data and Storage Settings, then Data and Storage, then Storage Usage.
- Read the chart Which type is the problem.
- Scroll to the chat list Which conversation is the problem.
- Clear per chat, not globally Tap the largest and clear it.
- Set the ceiling and the retention On the same screen. This is what stops it returning.
- Check the device figure afterwards Your phone's own storage screen will show the change once it recalculates, which can take a minute.
This page is reading the screen. The curriculum step is the model behind it: why local files are disposable, how a file is fetched back on demand, and why moving to a new phone transfers nothing at all.
