Just weeks before we expect to see the OPPO Find X9 Ultra, a trusted leaker has already tried out an EVT (Engineering Validation Test) unit. This stage checks if the design works before moving on to the next round of testing. The leak suggests OPPO is upgrading the battery size of its next Ultra model.
The EVT unit is said to feature a 7,050 mAh cell, according to Yogesh Brar’s post on X. That’s a huge jump from the Find X8 Ultra’s 6,100mAh, and it comfortably beats the Galaxy S25 Ultra’s 5,000mAh. However, it’s actually smaller than the Find X9 Pro’s battery capacity at 7,500mAh.
