OnePlus is currently busy working on a smaller device, the OnePlus 13T. This will feature a 6.3-inch screen, just like sister company Oppo’s Find X8S. The OnePlus 13T is in the rumor mill again thanks to its incredible battery capacity, especially for its size.

According to a new rumor from China, the 13T will manage to pack a whopping 6,200 mAh battery (with 80W wired charging support). For reference, note that the much larger OnePlus 13 only has a 6,000 mAh battery, so this is quite the feat of engineering.

That aside, past rumors haven’t been in much agreement about the number of cameras this phone will have – it’s either two or three. Either a 50 MP main and a 50 MP telephoto with 2x optical zoom, or those two plus an 8 MP ultrawide.

The OnePlus 13T is powered by the Snapdragon 8 Elite chipset, allegedly, and its screen comes with “1.5K” resolution and an embedded optical fingerprint sensor. The phone is expected to have a metal frame and a glass back. The OnePlus 13T is scheduled to become official in April, and it’s unfortunately still unclear if it will get a global launch.
