How to Free Up Storage on an Android Phone
Before deleting anything blindly, check what is actually eating the space — it is almost always photos, and Google Photos can clear those safely without losing a single one.
1. Check what is using the most space
Settings → Storage — it shows a breakdown by category (photos, apps, cache) so you can find the real problem before acting blindly.
2. Photos and videos (usually the biggest culprit)
Turn on backup in Google Photos, then use its "Free up space" feature — it uploads your photos to the cloud and safely deletes the local copies that are already backed up.
3. App cache
Settings → Storage → "Cached data" → you can clear it globally without losing any app data — only accumulated temporary files are removed.
4. Apps you no longer use
Review and uninstall apps you have not opened in months — many phones show directly when you last used each app, which makes the decision easy.
Tip: check your accumulated downloads too (the "Downloads" folder) — PDFs, images and files you no longer need tend to pile up unnoticed over time.
Frequently asked questions
Does clearing app cache delete my saved data?
No — it only removes accumulated temporary files. Your data, settings and signed-in sessions in each app remain intact.
Is it safe to free up space from photos already uploaded to Google Photos?
Yes — Google Photos' 'Free up space' feature only deletes local copies that are already safely backed up in the cloud, with no risk of losing the photos.
