A well-known insider has published the specs of a new Redmi smartphone with a 10,000 mAh battery and a 7-inch screen, which will be a step above the recently announced Redmi K90 Max, whose battery is rated at 8,550 mAh. This kind of battery capacity is typically found in tablets, not phones. The device is reportedly set to launch before the end of 2026, but Xiaomi has not confirmed anything yet.

What We Know About the Redmi K100 Pro Max
The information appeared on the Chinese platform Weibo from Digital Chat Station — an insider whose data frequently turns out to be accurate. The model name was not specified in the post, but the community leans toward it being the Redmi K100 Pro Max smartphone — the successor to last year’s Redmi K90 Pro Max.
Here’s what the leak mentions:
- 7-inch display with 2K resolution
- 10,000 mAh battery
- Processor built on a 3nm process
- Metal frame
- Ultrasonic under-display fingerprint scanner
- IP68/IP69 water and dust protection
All of this is unconfirmed data, and it should be treated as a rumor. Xiaomi has not officially announced either the model or a release date.
Differences Between Redmi K100 Pro Max and Redmi K90 Pro Max
For comparison: the Redmi K90 Pro Max phone was released in October 2025 with a 6.9-inch screen and a 7,560 mAh battery. If the leak is accurate, the new model will feature a noticeably larger display and a battery nearly a third more capacious. The improvement in both parameters is significant.

In recent years, Xiaomi has been consistently increasing battery capacities in the Redmi lineup. In early 2026, the company released the Redmi Turbo 5 Max with a 9,000 mAh battery. And leaks from as early as 2025 indicated that Xiaomi was deliberately moving toward the 10,000 mAh mark.
The new rumor looks like a logical continuation of the trend born from the adoption of silicon-carbon battery technology.
Xiaomi Smartphone with the Largest Screen
A 7-inch screen is territory that Xiaomi has explored before. The Mi Max series with large displays was produced until 2018 and was quite popular among those who wanted maximum screen real estate without buying a tablet. After that, the company discontinued the lineup, but now it seems that the natural growth of smartphone screen sizes has led back to those same numbers.

A seven-inch phone is a device that won’t suit everyone. It will be great for watching videos, reading, and working with documents, but it will be too large for one-handed use. Essentially, this is a smartphone for those who previously chose phablets or small tablets.
Who Is the Redmi with a 10,000 mAh Battery For
10,000 mAh in a smartphone is potentially two to three days of battery life under normal usage scenarios. For people who are often away from an outlet — travelers, couriers, those who work in the field — this could be a compelling argument. Especially if the device maintains reasonable thickness and weight, which the leak unfortunately says nothing about.
A 2K display, 3nm chip, and ultrasonic fingerprint scanner — all of this points to flagship-level specs. The Redmi K series in China traditionally offers top-tier specifications at a more affordable price than the main Xiaomi lineup. But nothing is known about the price yet.
When Will the 7-Inch Redmi K100 Pro Max Be Released
Digital Chat Station is one of the most cited Chinese insiders, and his data is frequently confirmed. But this is still a leak without official confirmation. Xiaomi could change the specifications, postpone the timeline, or not release this model in the form described at all.

Moreover, the Redmi K series is sold primarily in China. These smartphones don’t always make it to the global market, and when they do, it’s often under different names and with a modified feature set. For Russian users, this means that even if the device launches, the easiest way to buy it will be through Chinese stores.
For now, the new Redmi K100 Pro Max is an interesting indicator of where the industry is heading: batteries are growing, screens are too, and Xiaomi remains one of the most aggressive players in this race. Expect more concrete details closer to fall 2026.
