HarmonyOS can further be optimized to run on just 64KB of RAM

The U.S. ban hammer pushed Huawei into a corner, and with no way to run Android on its devices, the company that was once poised to become the largest smartphone manufacturer in the world was now limited to its home turf in China.

Not wanting to accept its fate, Huawei introduced HarmonyOS, its microkernel-based platform capable of running on different classes of products, and during the company’s keynote, an executive mentioned that the operating system can be optimized to run on measly 64KB of RAM. That’s not even an entire megabyte.

HarmonyOS can currently operate on just 128KB of memory, with further optimizations in tow, hinting at the platform running in low-power applications

At the Huawei Developer Conference 2026, Yu Chengdong confessed that HarmonyOS is so memory optimized that it only requires 128KB of RAM to run on various platforms. Where Windows and Android are memory guzzlers, Huawei’s operating system is going in the other direction, and it’s for one reason only; expanding upon the ecosystem.

In the future, HarmonyOS won’t just be limited to running on 128KB of RAM, but there are plans to optimize it for 64KB of RAM too. The ability of the operating system to be able to consume laughably low amounts of memory means that HarmonyOS can be tailor-made to run in IoT devices, where the efficiency level is something that even smartphones and tablets cannot achieve.

During the keynote, the Huawei executive also stated that HarmonyOS could run on just one dry cell for the entire year, showcasing the possibility of how the platform can operate when connected to an IoT device that’s outfitted with a sizable battery capacity. In addition to optimizing its operating system, Huawei is also motivated to upgrade its chip technology with an architecture called LogicFolding.

This packaging aims to boost chip density while also targeting increased clock speeds to deliver a major performance boost without the use of EUV equipment. Huawei aims to achieve these milestones with the help of existing DUV machinery, with the combination of HarmonyOS aiming to introduce an entirely new ecosystem to the table.
