A well-known Chinese tipster said today that a new performance-focused handset from a Xiaomi sub-brand is tentatively scheduled for later this year, and the biggest talking point is easy to spot: a 10,000mAh battery-class power pack. If the leak holds up, it would be the first Xiaomi phone to reach that battery tier.
According to the post, the device is expected to use a 3nm chip, a 7-inch 2K display, a metal frame, 3D ultrasonic fingerprint recognition, and full IP68 / IP69 water resistance. That combination suggests a phone aimed at buyers who want long battery life without giving up the sort of hardware features usually associated with higher-end performance models.

Based on hints from the source and speculation in the comment section, the phone is widely expected to come from REDMI. The report stops short of naming a final commercial model, so for now this still sits firmly in rumor territory rather than confirmed product planning.
The same tipster had previously said in April that a sub-brand midrange line would be among the first to adopt a 10,000mAh-class battery, along with 100W fast charging, a 200MP large-sensor main camera, a metal frame, optical fingerprint recognition, a large high-refresh 1.5K LTPS display, and a Dimensity midrange chip. Not every one of those earlier details is repeated in today’s post, but together they help sketch the broader direction Chinese phone makers seem to be exploring.
The article also notes that other brands may be moving the same way. The tipster previously suggested that vivo-related models were getting close to a 10,000mAh battery milestone as well, with iQOO arriving a bit later in the cycle. A separate January leak also pointed to Honor continuing its own big-battery push in the upcoming X80 line.
If that trend keeps building, China’s smartphone market could be heading into a real wave of ultra-large-battery phones. For people who don’t care much about peak performance and mostly want lighter daily use with fewer trips to the charger, that could end up being one of the more practical hardware shifts to watch over the next several product cycles.
