The competition for flagship phones will get hotter next year. After Xiaomi, Vivo, and Oppo released their flagship series in China, now the latest rumors say Oppo is preparing a new monster: Find X9 Ultra, which is predicted to carry the biggest battery among all Ultra phones.

This information comes from a Chinese technology leaker, Smart Pikachu. He claims that Find X9 Ultra will be equipped with a giant battery maybe even reaching 7,000 mAh or more. Oppo himself had a bold slogan when launching the Find X9: In 2025, no 7000, no flagship. The sentence hints that all the next Oppo flagship must have a battery of at least 7,000 mAh.

In comparison, the Find X8 Pro carries a 5.910 mAh battery, while the Find X8 Ultra 6.100 mAh. If this rumor is true, the Find X9 Ultra will surpass both and may even be bigger than the Find X9 Pro, which is rumored to have a 7,500 mAh battery. That is, Oppo is really serious about making endurance the main weapon against rivals such as Xiaomi 17 Ultra and Vivo X300 Ultra.

In addition to battery capacity, Find X9 Ultra is also said to be carrying a 6.8-inch screen with 2K resolution and eye protection features (eye protection). In the camera sector, Oppo looks set to bring a significant improvement: a quad-camera system with two periscope cameras each using sensors larger than the previous generation. This combination is expected to provide a major improvement in macro mode, portrait, to optical zoom.

Another report states that the Find X9 Ultra series will launch simultaneously with Find X9s in the second quarter of 2026. However, there is one additional leak that is quite interesting Oppo is also reportedly developing an ultra-thin phone. It is not clear whether this device will enter the Find line or Reno, but many fans speculate the name Oppo Find Air will be the right choice, especially since Xiaomi has already worked on a similar project called Xiaomi 17 Air.

If these rumors are accurate, 2026 could be the year when Ultra really means ultra everything from power, performance, to super thin designs that will break new standards in the premium smartphone world.
