Smartphone makers have been steadily increasing battery capacities in recent months. March 2026 will see a handful of phones with huge batteries, including the Honor Magic V6, which offers one of the largest batteries on a foldable phone. Some other models even cross the 9,000mAh and 10,000mAh thresholds, signalling a clear industry shift toward longer battery life. Here’s a look at the phones with huge batteries that have launched or are expected to arrive in March 2026.
3Poco X8 Pro Max – 9,000mAh
The Poco X8 Pro Max is scheduled to launch globally on March 17. It is expected to become the largest battery phone from Poco so far. Reports suggest that the Indian variant may include a 9,000mAh battery, while the global model could feature a slightly smaller 8,550mAh unit.
The device is believed to be a rebranded version of China’s Redmi Turbo 5 Max, which also packs a 9,000mAh battery. If the specifications remain similar, the X8 Pro Max could offer a strong combination of performance and endurance in the upper mid-range segment.
