Huawei may be preparing a major software surprise for millions of long-time users, as new leaks suggest the Huawei Mate 40 series will receive the upcoming HarmonyOS 6 update later this year. If confirmed, the move would mark a rare example of extended flagship support well beyond typical industry timelines.
According to a tipster cited in Chinese tech circles, Huawei plans to roll out HarmonyOS 6 to the Mate 40 lineup in the second quarter of 2026. The update is expected to use API version 22 or 23, indicating deep system-level integration rather than a minor compatibility release.
A Flagship Lineup With a Massive User Base
The Huawei Mate 40 series occupies a unique place in Huawei’s history. Launched in 2020, it was the company’s last Mate flagship series released before U.S. sanctions took full effect. Powered by the Kirin 9000 chipset built on a 5nm process, the Mate 40 series combined cutting-edge hardware with Huawei’s in-house silicon strategy.
Since launch, Huawei is estimated to have sold more than 30 million Mate 40 units globally, creating one of the largest active flagship user bases in the company’s ecosystem. This scale has played a significant role in sustained user demand for continued system upgrades, with forums and social media platforms showing growing anticipation for HarmonyOS 6 support.
Hardware Still Capable of Supporting HarmonyOS 6
From a performance standpoint, the Kirin 9000 chipset remains competitive for everyday tasks. Its efficiency and processing power are widely regarded as sufficient to handle the requirements of newer HarmonyOS versions, removing one of the biggest barriers that usually prevents older devices from receiving major OS upgrades.
Currently, the Mate 40 series runs HarmonyOS 4.2, with recent updates such as version 4.2.0.192 delivering new security patches and early compatibility with select HarmonyOS 4.3 home screen features. Huawei’s continued OTA updates for the lineup already signal an unusually long software support cycle.
Camera and Display Still Competitive
Even by 2026 standards, the Mate 40 series remains well equipped. The rear camera system includes a 50MP Ultra Vision main camera with an f/1.9 aperture, a 20MP ultra-wide lens, and a 12MP telephoto camera with optical image stabilization. On the front, users get a 13MP Ultra Vision selfie camera alongside a 3D depth-sensing module.
The device also features a 6.76-inch OLED display with FHD+ resolution and a 90Hz refresh rate, specifications that still meet modern usability expectations and further justify Huawei’s confidence in extending its software life.
What HarmonyOS 6 Brings to the Mate 40
If the update materializes, HarmonyOS 6 is expected to significantly enhance the Mate 40 experience. Huawei claims the new OS delivers around 15% smoother performance and more than 35 minutes of additional battery life compared with HarmonyOS 5.
New features include artistic lock screen signatures, expanded dialect support for the Celia Assistant, and practical tools such as family-based fraud prevention. These additions are designed not only to improve aesthetics and usability, but also to address real-world concerns like security and digital wellbeing.
Breaking Industry Norms on Software Support
Traditionally, most smartphone manufacturers offer three to four years of major OS updates, after which devices receive limited or no system upgrades. Huawei’s reported plan to bring HarmonyOS 6 to a phone released in 2020 would significantly exceed this norm.
If confirmed, the update would represent a strong loyalty reward for Mate 40 users and reinforce Huawei’s strategy of maintaining long-term engagement within its ecosystem. It could also set a benchmark for other manufacturers on how to retain large, active user bases through extended software support.
Outlook
While Huawei has yet to officially confirm the HarmonyOS 6 rollout for the Mate 40 series, the confidence expressed by the tipster and Huawei’s recent update history lend credibility to the claim. Should the update arrive as expected in Q2 2026, it would breathe new life into one of Huawei’s most iconic flagship lineups and further strengthen HarmonyOS as a long-term platform rather than a short upgrade cycle.
For Mate 40 owners, HarmonyOS 6 could be more than just another update—it may be the clearest signal yet that Huawei intends to stand by its users well beyond conventional upgrade windows.
