Alleged OnePlus 13T battery size and launch timeframe tipped
Recent leaks have revealed that the Oppo Find X8S will be equipped with the Dimensity 9400 Plus and a 5,700mAh battery. The above leak talks about an upcoming 6.31-inch compact phone that will come equipped with a massive 6,200mAh battery.
While the source has not mentioned the name of the device, he does not seem to be talking about the Find X8S, as its battery size is already known to be 5,700mAh as per reports. Therefore, the new leak could suggest that despite having the same form factor as the Find X8S, the OnePlus 13T may pack a larger 6,200mAh battery. Since the X8S is launching on April 10, it appears that the 13T may break cover in the second half of the month.
An Oppo device with the PKX110 model number was recently approved by China’s 3C authority. This phone is believed to be the upcoming OnePlus 13T, and its certification revealed that it may support 80W charging. It is also speculated to support 50W wireless charging.
The OP13T is expected to feature a 6.31-inch OLED LTPO screen that offers a 1.5K resolution and a 120Hz refresh rate. Under the hood, the device could be equipped with the Snapdragon 8 Elite. It is said to be equipped with a 50-megapixel main camera with OIS and a 50-megapixel telephoto camera with 2x optical zoom support on the back. It is expected to come with other features, such as a metal frame, a glass back, and a short-focus in-screen fingerprint scanner.
