The era of the true “phablet” might be making an unexpected return. According to a recent revelation by the highly reputable tipster @DigitalChatStation on Weibo, a major smartphone manufacturer’s sub-brand is currently evaluating a brand-new device featuring a massive 7-inch flat display paired with a jaw-dropping 10,000mAh-level battery. Based on industry whispers and the fervent speculation of Chinese netizens in the comments, all signs point to this ambitious prototype belonging to Xiaomi’s Redmi brand. While the specific model name remains shrouded in mystery, this leak suggests Redmi is actively exploring the ultra-large display and extreme battery endurance segment.
Core Concept: 7-Inch Flat Screen Meets Extreme Battery Life
Without an official spec sheet, we have to look at the engineering reality of what @DigitalChatStation has shared. Building a device with these dimensions presents unique hardware challenges and targets a very specific user base:
-
The 7-Inch Threshold: Modern flagships have steadily grown in size, with devices like the rumored Xiaomi 17 Ultra, Huawei Mate 80 Pro Max, and Apple iPhone 17 Pro Max all settling around the 6.9-inch mark. Pushing past 7 inches with a flat display crosses the threshold from “large phone” into true “phablet” territory, previously championed by devices like the 2022 vivo X Note.
-
10,000mAh-Class Power Plant: Fitting a 10,000mAh battery into a smartphone chassis requires significant internal volume, which is exactly what a 7-inch footprint provides. However, thermal management and motherboard space become critical constraints.
-
Processor Speculation: As astute commenters on Weibo pointed out, when a leak emphasizes a giant screen and a massive battery but remains entirely silent on performance, it is highly probable that the device will utilize a mid-range to entry-level chipset. High-end silicon like the Snapdragon 8 Elite demands advanced cooling systems that would directly compete for the physical space required by a 10,000mAh cell.
The Spiritual Successor to the Xiaomi Mi Max?
For long-time Xiaomi fans, this rumor strikes a nostalgic chord. It echoes the legacy of the legendary Xiaomi Mi Max series, which was beloved for its gargantuan footprint and incredible battery endurance. The series concluded in 2018 with the Mi Max 3, a device that featured a then-unheard-of 6.9-inch display. While the Mi Max 3 utilized an 18:9 aspect ratio (an evolution from the ultra-wide 16:9 ratio of the earlier 6.44-inch Mi Max and Mi Max 2 models), its physical footprint was massive by the standards of its time. If REDMI is indeed reviving this form factor, it would serve as the spiritual successor to the Mi Max, bringing modern bezel-less design to a physically dominant chassis.
Market Impact: Who is this Giant Screen Phone For?
If Redmi green-lights this project, it won’t be aimed at the average consumer. A 7-inch device with a 10,000mAh battery is purpose-built for extreme power users. This includes long-haul drivers, delivery and logistics workers, outdoor enthusiasts, and heavy media consumers who prioritize multi-day battery life and maximum screen real estate over flagship processing power or sleek aesthetics. Currently, users seeking this level of battery life are forced to buy rugged, ultra-thick “brick” phones from niche brands. Redmi entering this space could democratize extreme battery endurance with reliable software and a more mainstream design.
