FAQ
Why is usable space less than advertised?
iOS itself takes 6–8 GB. Apps, system caches, and updates use additional space — typically 10–25 GB on an active device.
Does iCloud affect storage?
Yes — iCloud Photo Library can store originals in the cloud and keep optimized thumbnails on device, freeing significant local storage.
Are these estimates accurate?
