Frequently Asked Questions
Free Storage = Total Capacity − (OS Size + Apps + Photos + Videos + Music + Other). Our phone storage calculator adds all usage categories and subtracts from total to show available space.
Android OS typically uses 5–12GB. iOS uses 6–12GB. Additional system files, pre-installed apps, and recovery partitions can bring total system usage to 15–20GB on new devices.
The OS, pre-installed apps, and file system overhead consume significant storage. Additionally, manufacturers use decimal (1GB = 1 billion bytes) while phones display binary GB, causing an apparent discrepancy
Video files and photos typically consume the most storage. App data (especially games), offline music, and downloaded podcasts are the next largest consumers. The OS itself takes significant baseline storage.
Delete unused apps, clear app caches, remove downloaded content (videos, podcasts), back up photos to cloud and delete local copies, use streaming instead of downloading, and delete duplicate files.
For average users, 128GB is sufficient. Heavy photographers, 4K video creators, or gamers with large game installs may benefit from 256GB or more. Cloud storage can supplement any capacity.
Internal storage (flash memory) permanently stores apps, files, photos, and videos. RAM (Random Access Memory) is temporary working memory used by the processor to run active apps. They serve completely different purposes.
