Huawei’s October 22 event is for HarmonyOS 6.0. So, will the Mate 80 launch? Yes and no. We likely won’t get full specs or a sale date, but we might see the phone in action as the OS’s flagship vehicle. Let’s dive into the details.
When can we expect the Mate 80? Industry whispers point to a debut sometime between late October and November. However, Huawei is keeping its cards close, having not officially confirmed the launch date for its second major 2025 flagship.
In accordance with industry analysts monitoring Huawei’s supply chain, the company has recently accelerated production of its Mate 80 models, indicating advanced preparations for a launch.
In the middle of this hustle, Huawei all of a sudden announced a new launch event for HarmonyOS 6.0 on October 22, sparking speculations for the Mate 80 release.
Huawei has not officially confirmed which products will be featured. Nevertheless, following the event announcement, public speculation has intensified, with many consumers anticipating an official update regarding the Mate 80 series.
The possibility exists for Huawei to unveil Mate 80 details, using the smartphones to demonstrate their advanced tech. Given the lack of certainty, however, patience is the only prudent path forwar.
Huawei’s Richard Yu has form for this. Following his accidental Mate 70 timeline reveal last year, he has repeatedly teased “extraordinary” and “far ahead” devices, making any hint from him newsworthy.
Mate 80 series
Despite his teasers, the Mate 80 has been notably absent. All eyes are now on the upcoming event as the likely moment for Huawei to break its silence and highlight the flagship’s advanced features.
The Huawei Mate 80 series is generating significant pre-launch excitement, primarily centered on two key areas: its next-generation Chipset and advanced Cooling Technology. As a series known for performance, all eyes are on the new Kirin chipset. Its release marks a major step for Huawei, and the anticipation for this new version is immense.
This feature places Huawei in rare company, making it the second brand after Red Magic to leverage a cooling fan for superior chip performance. This commitment to cutting-edge thermal management is what makes the wait for the Mate 80 so compelling.

The battery race is on! After Honor’s Magic 8 series, a leak suggests Huawei is developing its own higher-density 7000mAh battery for a 2026 flagship. What do you think this means for phone design?
In accordance with leaker DigitalChatStation, the upcoming Huawei Mate 80 lineup is set to receive a major battery upgrade with a 6000mAh capacity.
Get ready for a huge battery boost! A new leak suggests Huawei’s 2026 flagship is in the works with a massive 7000mAh+ battery. That’s some serious power.
Inputs reveal the  company is working on a large single-cell battery with a capacity of 7150mAh and a typical value of 7300mAh± pack. This could be for the Pura 90 series or the Mate 90 smartphones (Pro+ or RS Ultimate Design).
While a 7000mAh battery in a flagship would be new for Huawei, the company has already released a device with this capacity: the mid-range Enjoy 60X. The key difference is that Huawei is now reportedly bringing this large battery to its premium handset line.
 huawei 7000mAh Smartphone
The Nova Y91 for the overseas market also has a 7000mAh battery and 6.95-inch screen. Being a budget-friendly handset, the device is doing great on the global platform.
Larger battery capacities translate directly to a longer usage time, which is particularly beneficial for demanding tasks. This allows users to enjoy their favorite games or watch movies for extended periods without having to constantly recharge their phone.
Honor is initiating a trend with a 7000mAh battery for its upcoming Magic 8 series, potentially in the Pro model. This move is expected to inspire other brands, including Huawei, to introduce similar high-capacity batteries in their 2026 flagship phones.
Huawei is reportedly preparing to launch its Mate 80 series in November, with the new handsets promising to bring eye-catching improvements compared to their predecessors.
