How regular cache cleaning can keep LINE running smoothly

A simple monthly cache clean-up, guided by expert Hiraisensei, can significantly enhance LINE’s performance without risking message loss, ensuring a smoother user experience for long-term users.

LINE can become sluggish over time, but the cause is often mundane rather than mysterious: cached data has built up inside the app. In a video shared on his YouTube channel, LINE specialist Hiraisensei explained that a regular clean-up can restore speed without risking messages or photos. He described the process as a safe way to remove unnecessary files that quietly accumulate during long-term use.

The approach begins in LINE’s settings, where users can move from the chat menu to data deletion and clear cache. Official LINE Help says cached data may slow the app, while deleting it does not remove chat history. The company also warns users to be careful with other deletion options, since those can affect important information. Hiraisensei advises carrying out this maintenance roughly once a month.

He also recommends tidying individual chat rooms, especially old group threads that are no longer needed. For iPhone users, one option is to use the operating system’s “offload app” feature, which refreshes the app while keeping its data. For Android users, the cleaner route is through the phone’s settings, where cache can be removed at device level. However, both Hiraisensei and LINE’s own guidance stress that users should not tap “clear storage” or “delete data” unless they intend to reset the app.

If the app remains slow after that, the last resort is to back up chats and reinstall LINE. That is a more disruptive step, but it can help when cache and room-by-room pruning are not enough. The wider advice from LINE’s support materials and technology guides is consistent: a little routine maintenance is usually enough to keep the app responsive.
