Vivo is reportedly experimenting with 8,000mAh and 9,000mAh batteries for mid-range devices expected to debut in 2026. This indicates another significant advancement in smartphone battery sizes. The firm is also gearing up its X500 flagship lineup for next year, with batteries exceeding 7,000mAh. Also, the X300 Ultra is likely to include a pack of over 6,000mAh.
It appears that we will see an even larger battery enhancement for smartphones in 2026. Vivo is experimenting with smartphones featuring 8,000mAh and 9,000mAh battery capacities. The brand plans to launch these groundbreaking phones in 2026.
This year, we’ve witnessed smartphones with impressive battery capacities. Some include the OnePlus 15, featuring a 7,300mAh battery, and the Xiaomi 17 Pro Max, which boasts a 7,500mAh battery pack.
Vivo’s flagship device, the Vivo X300 Pro, features a 6,510mAh battery in many regions. The battery capacity is remarkable, especially considering the 7,000mAh+ mentioned earlier.
Vivo Aiming to Launch Phones Featuring 8,000mAh and 9,000mAh Batteries
It appears that Vivo aims to raise the stakes even higher, and several other firms will likely follow suit. Vivo intends to launch smartphones featuring 8,000mAh and 9,000mAh battery capacities in 2026.
Vivo has more devices planned for 2026 beyond these 8,000mAh and 9,000mAh phones. Although, they will likely be mid-range smartphones.
The company is preparing to unveil the Vivo X500 next year to replace the Vivo X300 series. The X500 flagship models will feature battery packs exceeding 7,000mAh.
Several credible sources say that the series will feature batteries ranging between 8,000mAh – 9000mAh. However, the tipsters did not disclose the precise figures, but you can expect exceptionally large battery capacities. The Vivo X300 Ultra, expected to launch in Q2 next year, reportedly will not achieve the 7,000mAh capacity. It will continue to feature a 6,000mAh+ battery, which should be sufficient for the phone to deliver excellent battery life.
