Xiaomi Redmi K80
By Muhammad Tahir · Updated June 2026 · how we review
A 2K 120Hz screen, Snapdragon 8 Gen 3, a 6,550mAh battery and wireless charging for around $355 — the K80 is what happens when a flagship spec sheet meets a mid-range price. The catch is that it never officially left China.
Is the Redmi K80 still supported?
Our estimateSupported until November 2029 · Buy-by November 2027
✓ Yes — the Redmi K80 is expected to be supported until November 2029, roughly 3.3 more years.
Apple doesn't publish an end date, but iPhones have a consistent ~5-year update track record — on that basis the Redmi K80 should be supported until around November 2029. Buying it today still gets you about 3.3 years of safe use, and Apple's written legal minimum is 5 years (verified June 2026).

Frequently asked questions
How long will the Redmi K80 get updates?
We estimate support to November 2029 — four OS upgrades and five years of security patches from its November 2024 release. Xiaomi's K-series commitments are not published in the detail Samsung's or Google's are, so treat this as an estimate from the brand's track record rather than a written guarantee.
Can I use the Redmi K80 outside China?
Physically yes, practically with caveats. It launched as a China-only model, which means the ROM is the Chinese HyperOS build, Google services are not preinstalled, and cellular band support is tuned for Chinese carriers — some US and European 5G bands may be missing. Importers usually flash a global ROM, but that voids warranty and is not something to attempt casually.
How does the K80 compare to the K80 Pro?
The Pro costs around $145 more and adds a Snapdragon 8 Elite instead of the 8 Gen 3, a 50MP floating telephoto with 2.5x optical zoom, a 32MP ultra-wide instead of 8MP, and 120W wired plus 50W wireless charging. The standard K80 keeps the larger 6,550mAh battery. If you shoot photos, the Pro is the meaningful upgrade.
Is the K80's battery genuinely better than a flagship's?
Yes, by a wide margin on paper. 6,550mAh is roughly 35% more capacity than the 4,900mAh in a Galaxy S25+, achieved partly through silicon-carbon cell chemistry that packs more energy into the same volume. Combined with an efficient 4nm chip, two-day use is realistic for moderate users — something almost no Western-market flagship can claim.
