The Huawei G8 offers a spacious 5.5 inch display, just like the Mate S. It seems to sit right in the sweet-spot size-wise, as far as current market trends go. The panel itself is of the LCD technology, which is undoubtedly a cut-back from the AMOLED one on the Mate S, but still offers pretty nice quality.
In fact, OLED technology is more of a rarity in the Huawei realm with only a hand-full of devices utilizing it, like the Ascent P1 and Nexus 6P. Huawei can boast quite a few excellent implementation of LCD tech, like the Mate7 or P8 and the G8 delivers a superb viewing experience as well. The panel in question has a resolution of 1080 x 1920 pixels and a respectable pixel density of 401ppi, identical to the one on the Mate S. Images appear sharp with punchy and vivid colors.
In terms of color accuracy, the Huawei G8 screen is less than stellar with a Avg DeltaE of 5.7, but we've seen flagship phones do worse, so we're fine with it. Playing with the Color temperature slider we managed to get the color deviation down to Avg DeltaE 4.3, which is a borderline color calibrated result. And that's without the maximum brightness getting any hit at all. Overall, the screen is nice and the color accuracy deviation is unlikely to bother you.
The maximum screen brightness of 460nits is about average for a LCD unit, but is still dwarfed by the Mate7 with its 530 nits, not to mention the Motorola Moto X Play with its over 600 nits, not to mention camp Sony. Contrast on the G8 is also high, but yet again not as good as the Mate7 or Honor 7.

Sunlight legibility for the Huawei G8 is definitely above average in our current database, but again gets dwarfed by competitive offers by Samsung and Motorola.

Huawei G8 battery life
The Mate S is equipped with a 3000 mAh battery, sealed in behind the back panel. This is a good 300 mAh more than the Mate S and a clear upside to the extra weight and thickness of the unit. The LCD panel could potentially reduce said advantage, but numbers hint that it is actually not that far apart from the AMOLED unit of the Mate S in terms of power efficiency.
3000mAh are still far from the whopping 4100 mAh the Mate7 has at its disposal, but the G8 does a pretty good job of power management with a total endurance rating of about 70 hours (a bit more with one SIM card and a bit less with the duo working together). This is quite a lot better than the 60 hours the Mate S managed to clock in, but there are a few notes to be made.
Our proprietary rating denotes the number of hours the phone will be operational if you are to make an hour of 3G talks, web browsing and video playback per day. Such usage pattern is of course entirely artificial, but we've established it so our battery results are comparable across devices.
The proprietary score also includes a standby battery draw test, which is not featured in our battery test scorecard but is calculated in the total endurance rating. Our battery testing procedure is described in detail in case you want to learn more about it.
Connectivity
As previously mentioned, the Huawei G8 comes in both a single SIM and dual SIM variant. The latter offers dual standby, but the second SIM slot shares the tray with the microSD card slot, so having two active cellular connections has its tradeoff - you lose the option of using a microSD card.
The Huawei G8 comes with quad-band GSM 850 / 900 / 1800 / 1900 MHz, multi-band 3G (model and market dependent). LTE Cat.4 is supported for downlink speeds of up to 150Mbps.
Local connectivity is duly covered with dual-band Wi-Fi 802.11 a/b/g/n with hotspot support. Bluetooth v4.0 is on board as well, and so is GPS with A-GPS and GLONASS. NFC is enabled too.
