Chuwi Hi9 Air Review

Where to Buy: $199

We haven’t seen any good 4G tablets with Europe or more global bands. But that has changed with the Chuwi Hi9 Air. This 10.1″ Android 8.0 tablet has dual micro SIM support, 4G modem that supports the following LTE bands 1/2/3/5/7/8/20/40. And you don’t have to give up a SIM for your MicroSD card, the tablet also has FM Radio, GPS, 13MP rear camera and front 5MP camera.

Powering this all is the deca-core MediaTek MT6797 Helio X20. It’s paired up with a Mali T880 GPU clocked to 780Mhz, 80Mhz faster than the Alldocube X1’s T800 with is only running at 700Mhz.

The build is mostly metal on the rear, only the removable top is plastic and the paint is a very fingerprint prone matte coating. The screen is fully laminated with 2.5D glass and a sharp 2560 x 1600 resolution giving it a 16:10 aspect ratio. The battery is 8000mAh and is good for up to 7-8 hours of light use. Gaming this will drop down to 4-5 hours depending on the game and screen brightness used. Below is the full video review covering everything including DRM info, Treble support (Only partition A) performance, benchmarks, gaming and more.

The Chuwi Hi9 Air is a good tablet for the price, with better 4G Band coverage and a great screen. Performance is good, not perfect with some minor UI stutters at times. But it does perform better than the Alldocube X1 the other Helio X20 tablet tested. The build is better than the all plastic Chuwi Hi9, but not as good as the Teclast Master T10’s.

Where the tablet falls short is weak 4G signal on my unit, a 205 lux bright screen, yet this panel can do almost double the brightness. But for some reason Chuwi have limited this, possibly to increase battery life. Which I might add is decent if you’re not gaming all the time or doing something else demanding mostly on WiFi. Expect a few more OTA updates from Chuwi to address the camera application crashes and improve the UI performance.
