Vivo reportedly testing 12,000mAh battery phone; iQOO also readying a foldable

Demand for big-battery phones is rising in the smartphone market, and several companies are preparing handsets with higher-capacity batteries. Vivo is now reported to be making a major move in this race.

According to a new leak, Vivo is testing a smartphone with a battery of about 12,000mAh. The company is also said to be working on new foldable smartphones for both the Vivo and iQOO brands.

Chinese tipster Digital Chat Station shared the information on the social media platform Weibo. The tipster claims that a smartphone maker has begun mass production of a battery with a rated capacity of 11,970mAh. The leak does not name the company directly but mentions a "blue" brand, which is why the brand is believed to be Vivo.

If the information proves correct, Vivo could soon bring to market a phone with a battery of about 12,000mAh. A battery this large could considerably improve the phone's backup. However, the phone's name, features and launch date have not yet emerged.

The leak carries another important detail. Vivo is said to be considering a higher-capacity battery for its upcoming large-screen smartphones. This suggests the company may not limit itself to one model and could use big-battery technology across different smartphones. Users who game for long hours, watch videos or use their phones constantly could benefit. Even so, actual battery backup will also depend on the phone's processor, display and software optimisation.

Details of Vivo's upcoming foldable have also surfaced. According to the tipster, the company may introduce its next-generation foldable smartphone next year, in 2027. The company is currently weighing different options for its design, including a conventional large-screen foldable design and a form factor with a wider screen. The upcoming foldable could therefore show some new experiments in design.

Meanwhile, Vivo's sub-brand iQOO is also working on a new flagship smartphone, which is likely to have a mid-size display. According to a separate report, iQOO may launch a foldable smartphone with a wider screen in the second half of 2027. There is no official information yet on the name or other technical features of the device.

Overall, Vivo and iQOO appear to be preparing to strengthen their hold on the market through big batteries, new display technology and foldable smartphones. Smartphone enthusiasts are now watching for when the company officially confirms the leaked details.
