The leak focuses on materials and colors, and says almost nothing about specs. Per Android Authority, the standard metal-frame Band 10 Pro could weigh under 40 grams, while a Ceramic White edition may exceed 50 grams. The Band 9 Pro weighed less than 25 grams without its strap, the same report noted, meaning the ceramic variant could weigh more than double the tracker body of its predecessor.

That weight jump reflects a known tradeoff with premium ceramic construction: the material carries a watch-like finish and feel, but it adds meaningful mass for all-day wear. Buyers already have a reference point from the standard Band 10. GSMArena measured the Band 10's Pearl White Ceramic edition at 26 grams body-only and 44 grams with strap last year, so the Pro's ceramic build would represent a step up even from that baseline.

The metal-frame versions are said to come in black, white, silver, orange, and pink, Android Authority reported. The standard Band 10 launched in Black, Rose, and Silver, GSMArena confirmed last year, making the Pro's five-option palette a broader offering from day one.

The Pro line has historically moved away from the slim tracker shape toward a wider form with more screen real estate, closer to a smartwatch in profile, Gadgets & Wearables observed last year. The Band 9 Pro carried a 1.7-inch rectangular screen, and the Band 10 Pro may shift toward a squarer display format, Android Authority speculated today, though no render or certification image has confirmed that. The leaker also hints at either a larger battery or a larger screen, without specifying which. Specs beyond design details are absent from this leak.

A Xiaomi device registered as model number M2552B1 appeared in South Korea's National Radio Research Agency database last December, classified as a low-power Bluetooth device manufactured in China, Gadgets & Wearables reported in January. The filing includes no product name, photos, or manual. What it does carry is a model number that fits Xiaomi's established band-numbering pattern: Pro models have historically landed 70 to 100 positions above the base model in Xiaomi's internal scheme, the standard Band 10 is M2459B1, and M2552B1 falls precisely in that range, consistent with the Band 8 Pro and Band 9 Pro before it, per Gadgets & Wearables.

That's the site's own analytical inference, not a confirmed product name. The underlying pattern has held across multiple generations, which is what makes the inference credible rather than definitive. The same analysis found that Xiaomi has not historically moved to a new base generation before releasing the Pro variant of the current one, making a Band 11 designation for M2552B1 unlikely, though the identification remains speculative until Xiaomi confirms otherwise.

The filing shows a registered Xiaomi Bluetooth device exists. Combined with today's leak, that's a stronger evidentiary foundation than most pre-launch rumors carry at this stage.

The standard Band 10 ships with a 1.72-inch AMOLED display at 1,500 nits, a 9-axis sensor, updated health-tracking algorithms, heart-rate broadcasting, connected GPS, and a claimed 21-day battery life, GSMArena confirmed last year. That's a capable baseline the Pro needs to clear on specs, not just materials.

One former Pro exclusive has already migrated down. The electronic compass was unique to the Band 9 Pro in the previous generation, but it's now standard on the Band 10, Gadgets & Wearables noted last year, narrowing the functional gap before the Pro has even launched.

Built-in GPS is the feature most likely to anchor the upgrade case. Xiaomi kept the Band 10 on connected GPS rather than standalone, a decision that preserves the clearest reason to pay more for the Pro model, per Gadgets & Wearables. A barometric altimeter is also a plausible addition based on the same pattern analysis, though neither feature has been confirmed in the current leak.

For Band 10 owners, standalone GPS is the question. For Band 9 Pro owners, it's whether ceramic construction and an updated design represent enough forward movement. This leak speaks more to the second group than the first.

Leaker Digital Chat Station, cited by Android Authority today, suggests a launch as early as June 2026. One source, no corroboration from Xiaomi or secondary leakers.

Pattern analysis from Gadgets & Wearables last year placed the probable window between late August and early October, extrapolating from the Band 8 Pro and Band 9 Pro, both of which arrived several months after their respective base models. IFA, held in early September and an event Xiaomi regularly attends, was flagged as a plausible anchor. That analysis was written before any regulatory filing or design leak existed for the Band 10 Pro. Both have since arrived, Gadgets & Wearables noted in January, moving the timeline from speculative to credible.

A June launch is possible. A late-summer window fits the historical pattern better. The next signal worth watching isn't a date, though. It's the spec sheet: whether standalone GPS appears will settle the question of what kind of Pro this actually is. Materials justify a premium if the feature set does too. If the ceramic shell is doing most of the heavy lifting, the pricing math gets harder, and Xiaomi leads global wearables shipments on the strength of a series that has always given buyers a clear functional reason to step up, GSMArena noted last year. No official images, confirmed specs, or Xiaomi announcement exist yet.
