The OnePlus 13T proved that despite shipping with a smaller display, it did not compromise on the battery capacity and featured a 6,260mAh cell, with the majority of the credit going to adopting silicon-carbon technology. A rumor is now doing the rounds, claiming that the company is working on yet another Snapdragon 8 Elite flagship, but this time, the device will be outfitted with an even larger 7,800mAh battery.
A re-arrangement of the logic board components will probably be required to introduce a battery size of 7,800mAh to the OnePlus flagship
With Chinese phone makers transitioning to silicon-carbon battery technology in droves, they have started to get much busier in launching premium and mid-ranged devices with battery sizes that would not have been thought possible if the main goals were to maintain other features such as a versatile camera configuration and reasonable thickness. In 2025, more and more smartphones bearing batteries of 6,000mAh and above are possible because of silicon-carbon technology.
On Weibo, tipster Digital Chat Station has commented that OnePlus is working on a new Snapdragon 8 Elite flagship with a 7,800mAh battery. With the OnePlus 13T, the company showcased how it crammed a 6,260mAh cell, and while the engineers did re-arrange the components to help reach the aforementioned in a flagship whose display size was a relatively compact 6.32 inches, it only shipped with a dual-camera array at the back.
For the latest rumor, the tipster has not mentioned how large the flagship’s panel will be, and if OnePlus needs to resort to some clever engineering to be able to accommodate that mammoth 7,800mAh battery. Sadly, the majority of the details are in the dark at this time, so once we get hold of more details, we will relay that information to our readers. Keep in mind that OnePlus has slowly been increasing the battery capacity of its top-end smartphones, so it is more than likely that it will realize its goal with the new flagship release.
