Oppo and Vivo reportedly working on phones with batteries of about 12,000mAh

Smartphone makers are competing over battery capacity, with the size of the battery now counting for more than features. Big brands such as Oppo and Vivo are reportedly preparing to launch phones with batteries of around 12,000mAh. If that happens, a phone could be used for several days on a single charge.

Oppo's upcoming model, 'PNC110', is the subject of much talk in the tech world. The phone has appeared in a listing on China's MIIT. According to the leak, it has a purple back panel with a pill-shaped camera module. It has a dual-lens camera setup, and an 'AI camera system' logo is also visible.

The power and volume buttons are on one edge, on either the right or the left. The front has a flat display with a punch-hole cutout. The phone may have a large battery of about 11,640mAh to 12,000mAh. It is likely to be launched under Oppo's popular 'A series'.

Oppo's earlier model, the A7 Pro Max, already comes with a 10,000mAh battery. Given its popularity, interest in the new model has grown further.

Vivo is not lagging behind either. According to the well-known leaker 'Digital Chat Station', Vivo is working on a battery with a rated capacity of about 11,970mAh. The company is also working rapidly on its upcoming foldable smartphone and a flagship device under the 'iQOO' brand. New foldable and large-display Vivo devices could appear in the market in the coming period.

Batteries of 10,000mAh to 12,000mAh are fast becoming a trend. Brands such as Oppo, Vivo, Honor and Realme have already brought out phones with batteries of around 10,000mAh. If these 12,000mAh phones arrive, users will get considerable relief from the hassle of charging.

For now, neither company has announced an official launch date, price or name for these upcoming phones.
