Nowadays, smartphone technology is always marching forward but battery life still seems to be lagging behind. Battery life is still a perennial problem for smartphone owners. Aimed at this issue, the CUBOT has released a new smartphone called H3 which comes with a 6000mAh battery, supporting standby for two days for heavy users. Today, let’s have a look at this new smartphone from CUBOT.

Design & Display

The design of the CUBOT H3 isn’t anything special. Due to the built-in 6000mAh large battery, the thickness is 11.2mm, a bit thick. The H3 is available in black and golden option and made of metal frame and plastic rear cover. It comes with a 5.0″ display and sports a dual rear camera at its rear panel with a fingerprint sensor at the top middle. 2.5D curved glass is used to cover the screen. The screen-to-body ratio is about 70%. This IPS LCD display supports a resolution of 1280 x 720 pixels, with a pixel density of 294 ppi. On the bottom of the front panel, there are three touch keys with metal coating including menu, home key and back key, recognizable to see. On the top of front panel, there is the phone receiver and the front camera.


On the four sides of this handset, you will find that the speakers are located on the bottom edge of the handset. On the top edge, there is a 3. 5mm headphone Jack and a microUSB charging interface. On the right side, there is the volume and power keys. There is no SIM card / TF card slot on the left side of the handset. Thus, the SIM card and TF should be put through taking off the back panel.

Hardware & OS

The CUBOT H3 comes with a MTK6737 processor, quad-core, clocked at 1.3GHz, along with 3GB RAM and 32GB of internal storage. This configuration is not bad, just as expected for the price. If you think that 32GB is not enough for you, you can also sacrifice the 2nd SIM slot to add an extra 128GB microSD card. As for GPU, this handset is coupled with the ARM Mali-T720, that can handle most games with ease. The H3 runs on the Android v7.0 Nougat OS.


The CUBOT H3 has a 13MP plus 0.3 MP dual camera, with F/2.0 large aperture and PDAF phase focus technology on the rear panel. Moreover, a LED flash is offered for brightening the scene. But as the it is a budget phone, you cannot expect to get a great performance from the dual rear cameras. As for selfie, there is a 5MP front camera.


The 6000mAh battery is the highlight feature of the CUBOT H3. It’s a Lithium Polymer battery that is non-removable. It’s expected to last at least two full days of heavy use and possible into 3 days if you’re a light user. Moreover, the H3 supports fast charging that ensures to charge faster.
