Here are six top smartphones available or widely sold in 2025 that offer the largest on-device storage options (512GB–1TB), with notes about availability and why their storage setups suit heavy users.

Buy tips for Bangladesh
- Confirm the SKU: 1TB variants are often region-limited (China/India/Global). Always check the official seller or authorized retailer in Bangladesh before purchase.
- Prefer UFS 4.0 storage where possible — faster app installs and file transfers. Many 2024–25 flagships use UFS 4.0.
- Backups: Even with 1TB, have a cloud or external backup for irreplaceable footage.
- Price vs need: 1TB models are expensive — if you mainly stream and take occasional 4K clips, 512GB + external cloud may be more cost-effective.
