Huawei Mate 80 will keep the familiar round camera design
Huawei Mate 80 is expected to still use the characteristic circular camera cluster, but add an active cooling fan, 6000mAh battery and possibly eSIM support.
Quick summary:
Mate 80 still uses the familiar round camera design from Mate 30.
There may be some slight tweaks in appearance compared to the Mate 70.
Expected to be equipped with an active cooling fan – a first for the Mate series.
eSIM support is being tested and could appear on the Mate 80.
Most likely to have a battery over 6000mAh and a new Kirin processor.
Huawei Mate 80 remains loyal to the circular camera design but may "hide" major upgrades
The upcoming Huawei Mate 80 series will continue to maintain the circular camera design that has become a symbol of the Mate series for many years. However, besides the familiar design, the device is expected to have significant changes in the technology inside.

According to the leak from Weibo account @SmartPikachu, Mate 80 still retains the circular camera cluster on the back, similar to the design starting with the Mate 30 series in 2019.
Previously, Huawei used a small square camera cluster on the Mate 20, but the aesthetic and recognition success of the Mate 30 made the company decide to stick with the round design since then.
However, each generation still has slight changes. For example:
The Mate 60 Pro has the same design as the Mate 40 Pro.
The Mate 70 is reminiscent of the Mate 50's camera style.
And with the Mate 80, Huawei is expected to keep the overall round design, but there may be small tweaks to create a fresh look.
Active cooling fan: First appearance on Mate series?

One notable point in this leak is that the Mate 80 could be equipped with an active cooling fan, a technology that usually only appears on gaming smartphones.
Information about this cooling technology has appeared in recent rumors, and it is highly likely that Huawei will bring this feature to the upcoming flagship line to solve the problem of high performance and temperature.
eSIM and huge battery: Is Huawei “quietly upgrading”?
In addition to the cooling system, Huawei is also testing the ability to support eSIM - an electronic SIM card that replaces the traditional physical SIM card. According to the source, eSIM will appear first on the tri-fold phone model, then be expanded to the Mate 80.
If true, this would be a major step forward for Huawei users in modern markets where eSIMs are increasingly popular.
Not stopping there, Mate 80 is also expected to be equipped with a battery of up to more than 6000mAh, helping to extend usage time compared to previous generations, which fluctuated around 5000mAh.
New Kirin chip, the heart of Mate 80?
Huawei has yet to reveal details about the processor equipped for the Mate 80 series. However, it is expected that the device will use a new generation Kirin chip, which can be an upgrade from the Kirin 9000s or a completely new line, compatible with AI technology and high-end graphics processing.

Details about the new Kirin chip have yet to be confirmed, but tech insiders predict it will be a key pillar of the Mate 80 in competing with other Android flagships.
From a design perspective, the Mate 80 may not be a big surprise, but it's the "silent upgrades" like active cooling, large battery, eSIM support, and powerful chip that make it attractive.
Keeping the circular camera design could be Huawei's way of maintaining its identity, while inside are a series of improvements serving performance, connectivity and real-world experience.
