Realme is gearing up to push smartphone battery capacity to new heights with a 10,000mAh phone expected to launch at the start of 2026. This marks a significant leap in battery size for a regular-sized phone, following earlier prototypes that impressed with slim designs around 8.5mm thick and weighing just 215 grams.

Realme’s Vice President Chase Xu confirmed the release timeline, though it’s unclear if the upcoming device will be based on the innovative Realme Chill Fan Phone concept showcased earlier this year. That concept integrates a cooling fan and a Peltier thermoelectric cooler to manage the heat generated by such large batteries.

Alongside the 10,000mAh model, Realme has also teased a future device boasting an astonishing 15,000mAh battery, hinting at an ongoing commitment to redefining battery endurance on smartphones.

In the meantime, Realme is expected to release a phone with a 7,500mAh battery later this year, bridging the gap between current models with 7,000mAh and 7,200mAh batteries (like the Neo7 Turbo and GT7 in China) and the larger 10,000mAh powerhouse coming soon.

This move clearly signals Realme’s ambition to offer longer-lasting smartphones without compromising form factor, cooling, or usability. Battery life enthusiasts can look forward to exciting innovations as these devices hit the market in the near future.
