Recommended storage tier
256 GB
Keeps approximately 20% capacity in reserveHow this calculator helps
Estimate storage needed before choosing a 128 GB, 256 GB or larger phone. The calculation adds app and personal-media needs, then preserves free space for system updates, caches and smooth operation.
How to use it
- 1
Estimate installed app and game storage after updates.
- 2
Add current and expected photo, document and offline-media usage.
- 3
Keep a free-space reserve and choose the next available storage tier.
Formula and methodology
Required capacity = (apps and games + photos and files + video) รท (1 โ reserve percentage), rounded up to a common storage tier.
Worked calculation example
If apps need 55 GB, other files 35 GB and video 30 GB, keeping 20% free requires about 150 GB, so a 256 GB tier is the safer choice.
What can affect the result?
System storage
The operating system and preinstalled software consume part of advertised capacity.
Media growth
High-resolution video and messaging-media caches grow quickly.
Cloud reliance
Cloud storage saves local space but requires connectivity and may have recurring cost.
Limits of this estimate
The estimate cannot forecast app growth, system size, cache behaviour, future recording habits or the exact usable capacity of a specific phone.
