Blackview WAVE 10 4G phone, 256GB, 6.88-inch

The Blackview WAVE 10 is a 4G unlocked phone with 256GB storage, an 8GB RAM listing and a large 6.88-inch display. Its 720×1640 resolution is a modest match for buyers who prioritise screen size and storage over a sharper panel. The listing also claims a 120Hz refresh rate and a 5000mAh battery, but its battery energy and life fields do not align clearly with that capacity claim.

What to know before buying

The 5000mAh battery and 10W adapter are manufacturer feature claims. Battery life is said to vary with signal, brightness and app use.
A 3-year manufacturer warranty is claimed, with terms and exclusions applying.

Listing details to confirm

Listing details are contradictory or inconsistent: battery capacity is claimed as 5000mAh in feature text, while the specification gives 5 Watt Hours and 336 Hours average life; expandable storage is described as up to 2TB in feature text but the maximum flash memory field says 256 GB; the title calls the screen 6.88 inches while other fields use the same size in inches, and the screen is described as IPS in feature text but LCD in specifications. Confirm the selected variant's battery, card capacity and display details before purchase. The 8GB RAM field is distinct from the model label 32GB+256GB and must not be read as 32GB of physical RAM. The listing warns that 4G calling and data depend on local coverage and compatible networks, SIM plan and VoLTE support. Check with your carrier, especially for use while travelling.

The supplied evidence contains aggregate ratings but no customer comments or aspect-level feedback. The distribution is mostly five-star, with a smaller low-star share, so it suggests generally favourable ratings alongside some dissatisfaction without showing what caused either. Ratings alone cannot establish performance, battery experience or network compatibility.

Frequently asked questions

Does the Blackview WAVE 10 support 5G?

No. The listing specifies 4G and explicitly says 5G is not supported.

How much RAM and storage does this listing specify?

It lists 8 GB RAM and 256 GB storage. The model label says 32GB+256GB, but that does not establish 32GB of physical RAM. Feature text separately claims virtual memory expansion.

How much expandable storage does it support?

The feature text claims a dedicated microSD slot supporting up to 2TB, but the flash memory specification says 256 GB maximum. Confirm the limit for the selected version before buying.

What is the display resolution?

The listing specifies 720×1640 on a 6.88-inch screen, which is below Full HD.
