Xiaomi 17 Max lands in China with 8,000 mAh battery and Leica HP9

UPDATED · News · 25 May 2026 · MTW Editorial Team

The Xiaomi 17 Max goes on sale in China today, 25 May 2026, four days after Lei Jun unveiled it at a Beijing launch alongside the YU7 GT electric SUV and the Band 10 Pro. Xiaomi confirmed the 17 Max ships with an 8,000 mAh silicon-carbon battery, a Snapdragon 8 Elite Gen 5, and the first 200 MP Samsung HP9 Leica camera tuned for any Xiaomi phone, starting at CNY 4,799 (about £530 (about $670) / GBP540 / EUR620) for the 12 GB plus 256 GB trim.

Why the Xiaomi 17 Max matters in 2026

The Xiaomi 17 Max is the model Xiaomi designed to win the China flagship spec sheet against the Vivo X300 Pro, Oppo Find X9 Pro, and Huawei Mate 80 RS. It is not the global Xiaomi 17 Ultra that Pixel and Galaxy fans have been comparing for months. It is bigger, heavier, and built around a 6.9-inch display that bends just enough at the four edges to feel modern without sliding into the waterfall-display dead end the industry abandoned in 2024.

The hook for the Xiaomi 17 Max is the 8,000 mAh silicon-carbon battery in a 9.4 mm body. That is a 60 percent jump in cell capacity over the Xiaomi 14 Ultra at the same physical thickness, and it is the headline Xiaomi will spend the next twelve months hammering. 100 W wired and 50 W wireless charging keep the refill story competitive, although the iPhone 17 Pro Max still beats it on wireless thermals.

Xiaomi 17 Max cameras: Leica HP9 and a real 3x telephoto

Xiaomi paired the Samsung HP9 200 MP sensor with a Summilux f/1.9 lens and OIS, and the rear array also carries a 50 MP periscope telephoto with optical 3x reach and a 50 MP ultrawide with a 102-degree field of view. That is the kind of triplet Xiaomi reserved for its Ultra phones in past generations, and dropping it into the Max trim is the clearest sign yet that Xiaomi sees the 17 Ultra as an export-only model. The Leica colour science is selectable between Vibrant and Authentic, with the new Leica Master Lens portrait modes carrying over from the iPhone 17 Pro broadcast push.

Where the Xiaomi 17 Max actually pulls away from the Galaxy S26 Ultra is in low light. Xiaomi published sample frames at the launch event that show four-stop noise reduction headroom over the Mate 80 RS and roughly two stops over the iPhone 17 Pro Max, claims that should hold up when independent labs publish their tests later this week. The selfie camera is a 32 MP fixed-focus unit, which is the spec sheet’s only obvious sacrifice and a regression versus the 17 Ultra’s autofocus selfie.

Xiaomi 17 Max price, colours and where to buy

The Xiaomi 17 Max ships in Pixel Black, Sky Blue, and White. Xiaomi has not confirmed a global launch and history says the Max trim stays Chinese; expect grey importers to land it on AliExpress within ten days. UK and EU buyers waiting on the Xiaomi 17 Ultra global model should hold their fire because Xiaomi has been clear the 17 Max and 17 Ultra are different products. There is no announced US carrier deal and Xiaomi does not sell smartphones at retail in the US.

What Xiaomi 17 Max buyers should watch

HyperOS 3 ships out of the box, based on Android 16, and Xiaomi is promising four major Android updates plus six years of security patches. That trails Samsung and Google by a year, and the Xiaomi 17 Max needs to close that gap before it is taken seriously by enterprise buyers outside China. The AI suite, branded HyperAI, runs Xiaomi’s own MiLM 2.0 model locally on the Snapdragon 8 Elite Gen 5 NPU for transcription, summarization, and Image Playground-style editing. It is comparable to the Claude on-device push in scope, but Xiaomi keeps the cloud handoff opaque.

The buy case for the Xiaomi 17 Max is straightforward. If you import flagships, this is the phone that pairs a real 8,000 mAh cell with a Leica HP9, and pays for itself against the iPhone 17 Pro Max on storage and charging. If you do not import, wait. Xiaomi will not bring the 17 Max to UK or EU retail, and the global Xiaomi 17 Ultra later this year will deliver most of these specs with proper warranty cover and 5G bands that work outside China. Compare it against the rest of our 2026 phone picks before you place the import order.

Xiaomi 17 Max vs Xiaomi 17 Ultra

The simplest summary is this: the Xiaomi 17 Max is the China-only spec champion, while the Xiaomi 17 Ultra is the Leica-branded photographer’s phone Xiaomi sells globally. Both run Snapdragon 8 Elite Gen 5. Both run HyperOS 3. The 17 Max wins on battery (8,000 mAh vs 6,000 mAh), wired charging (100 W vs 90 W), and panel size (6.9 vs 6.73 inches). The 17 Ultra wins on telephoto (a longer 4.3x periscope), tripod ecosystem accessories, and a global five-year warranty. UK and EU readers comparing the Xiaomi 17 Max to our best iPhone UK picks should accept the warranty gap is the real differentiator, not the spec sheet.

One under-reported feature is the under-display fingerprint reader. Xiaomi switched to a Goodix ultrasonic sensor on the Xiaomi 17 Max, the same supplier Samsung uses on the Galaxy S26 Ultra, and the placement is two-thirds of the way up the screen for easier one-handed reach. That sounds trivial, but anyone moving from the optical sensor on a Xiaomi 14 Ultra will notice the difference within a day. IP68 dust and water resistance is confirmed; the 17 Max does not get the IP69 rating the Realme 16T just shipped with, and Xiaomi has not explained why.
