Storage Usage.

Storage Usage. Telegram needs zero extra space to run on your device. You can clear cached media from your phone, while keeping it in your chats – ready to be re-downloaded at any time.

Just head to Settings > Data and Storage > Storage Usage and try one (or all 💪) of these options:

1) Set up Auto-Remove to clear cached media after a certain period with separate settings for Private Chats, Groups and Channels – and exceptions for individual chats.

2) Set a maximum cache size – if your cache reaches this limit, the oldest media will be removed.

3) Find the largest media items with dedicated tabs and detailed pie charts and manually clear them from your cache or select specific chats that take too much space.
