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.
1Realme Narzo Power – 10,001mAh
Launched earlier this month, the Realme Narzo Power stands out as the phone with the largest battery in this list. It houses an enormous 10,001mAh battery, which is far larger than the capacity typically seen in mainstream smartphones. The device also features 80W wired charging, allowing the massive battery to refill relatively quickly.
In addition to battery endurance, the Narzo Power offers competitive hardware for its segment. It features a 144Hz curved-edge AMOLED display, the MediaTek Dimensity 7400 chipset, and a 50-megapixel dual-camera system. The phone is priced from Rs 26,999 (~$295), positioning it as a mid-range device with an unusually large battery.
