Phone Storage & Capacity Estimator

How to calculate phone storage usage?

Usage is calculated by multiplying media counts by average file sizes and adding system overhead and app data weights.

Formula: Total = System + (Photos × 0.003GB) + (Videos × 0.15GB) + (Apps × ProfileWeight)

Using the storage estimator: an example

Example: A 128GB phone with 2,000 photos, 40 videos, and 50 'Balanced' apps.

Step-by-step calculation:

• Photos: 2,000 × 0.003 = 6GB
• Videos: 40 × 0.15 = 6GB
• Apps: 50 × 0.5GB = 25GB
• Total (incl. 15GB System): 52GB used (40% capacity)

Frequently Asked Questions

What is 'System Data' or 'Other'?

This includes the operating system, system logs, cache files, and temporary assets that the phone needs to run smoothly.

How much space does 4K video use?

One minute of 4K video at 60fps can take up to 400MB, which is significantly higher than standard HD video.

Why is my available space less than advertised?

Manufacturers define 1GB as 1 billion bytes, whereas operating systems use binary (1024MB), leading to a ~7% discrepancy in reported size.
