Cleaning your phone shouldn't be seen solely as a matter of aesthetics or freeing up space. In fact, doing periodic cleanings has a direct impact on the performance, safety and device lifespanOver time, any smartphone stores:
- Temporary files (app cache, obsolete downloads, thumbnails)
- Data from unused apps, remnants of uninstalled applications and duplicate files
- Repeated images and videos or low quality
- Old documents and chats saved by messaging apps
