Xiaomi 17 Ultra has been making quite a presence in the rumor mill lately, and today it’s making headlines again as the device has secured 3C certification in China.
The 17 Ultra is said to come in two versions. One, carrying the model number 2512BPNDAC, is the standard variant, while 25128PNA1C is the dual-satellite communication version, supporting both Tiantong-1 satellite calling and Beidou short-message communication.
For those unaware, Tiantong-1 and Beidou are satellite services that enable voice calls and message exchange.
Xiaomi 17 Ultra supports 100W charging
The 3C certification further confirms that the Xiaomi 17 Ultra will support 100W wired charging as standard. For comparison, the Xiaomi 15 Ultra supports 90W charging.

This faster charging should prove useful, as the device is also expected to house a larger battery. For reference, the Xiaomi 17 Pro Max released earlier this year is equipped with a 7,500mAh cell.
Both Xiaomi 17 Ultra variants have also passed China’s radio certification, which confirms UWB (Ultra-Wideband) support on both models. UWB is useful for seamless connectivity across ecosystem devices, including a remote car unlock.
Of course, the highlight of any “Ultra” model is always the camera setup, and the Xiaomi 17 Ultra doesn’t seem to disappoint on paper. It’s rumored to feature a quad-camera array with the following hardware:
- Main: Omnivision OV50X, 50MP (1-inch sensor)
- Ultra-wide: Samsung JN5, 50MP
- Telephoto: Samsung JN5, 50MP
- Periscope telephoto: ISOCELL HP5, 200MP
On the front, the device could sport a 6.85-inch LTPO OLED display with 2K resolution and ultra-narrow bezels, reportedly slimmer than what you get on the iPhone.
Under the hood, it’s expected to be powered by Qualcomm’s Snapdragon 8 Elite Gen 5, IP-rated water resistance, and what’s likely to be one of the largest batteries in Xiaomi’s flagship lineup.
