Battery capacities have been increasing at an unexpected pace over the past year, and Oppo may be preparing one of the most significant advancements yet.
According to reports, the company is testing a new mid-range smartphone that features a battery rated at approximately 9,700mAh, with typical capacity reportedly reaching the 10,000mAh mark. If these claims are accurate, the device would surpass many of today’s battery-focused smartphones.
Earlier reports from late 2025 suggested the development of a massive single-cell battery entering trial production, with a rated capacity of around 9,750mAh and a typical value close to 10,000mAh. At the time, this seemed more like a glimpse into future hardware rather than something likely to appear in a commercial phone soon.
The leaked device is said to use a 4nm-based chipset, paired with a flat LTPS display that has a resolution around the 1.5K mark. The phone reportedly uses high-polymer impact-resistant materials and elements of the company’s “diamond architecture” design, which has appeared in several recent devices aimed at improving drop resistance.
The rumored price is perhaps the most surprising detail. According to Digital Chat Station, the device is being positioned around the 2,000 yuan range (roughly €253 at the current exchange rate), which would place it firmly in the mid-range segment rather than the premium category.
Of course, battery capacity alone never tells the whole story. Software optimization, charging speeds, thermal management, and overall efficiency matter just as much. Still, the idea of a mainstream smartphone approaching the 10,000mAh mark would have sounded unrealistic not very long ago.
There are already a handful of smartphones from Realme and Honor that ship with 10,000mAh batteries, including the Realme P4 Power, Realme Narzo Power, Honor Power 2, Honor Win, and Honor WIN RT. It will be interesting to see how quickly the rest of the industry follows, if at all, once 10,000mAh batteries become commonplace in Chinese smartphones.
- This development could signal a shift in the market, where battery life becomes a key differentiator even for mid-range devices.
- The combination of a large battery with a 4nm chipset suggests that Oppo is aiming for both performance and endurance.
- The use of impact-resistant materials and diamond architecture highlights the company’s focus on durability.
- A price point of 2,000 yuan could make this device highly competitive in the mid-range segment.
