Chinese smartphone makers OnePlus and OPPO are reportedly testing a massive 8,000mAh battery for their future phones. According to the reliable gadget tipster Digital Chat Station, the companies have started testing this beefy battery technology. It’s worth mentioning that OnePlus has been developing a massive 7,000mAh battery for its upcoming phones since last year.
OnePlus and OPPO have started testing a massive battery to deliver enhanced life on their future phones
As per the Chinese tipster, OPPO and OnePlus are developing a powerful new battery system. It has a massive 8,000mAh battery, which supports 80W fast wired charging. That’s 60% larger than the standard, which is 5000mAh. Furthermore, the source claims that OnePlus and OPPO are using 15 percent high-silicon materials to make this battery. So, future OnePlus and OPPO mid-range and flagship smartphones could see significant battery life improvements.
While the leaker hasn’t explicitly mentioned any names of these brands, he claims ‘Omega Labs’ (machine translated), which many believe refers to OnePlus and OPPO. Beyond this, the tipster hasn’t shared any other details regarding the new 8,000mAh battery technology. Last year, a report indicated that OnePlus was working on a 7,000mAh battery. OPPO’s subsidiary Realme has also been developing an 8,000mAh battery with 80W fast charging since last year.
OnePlus could first offer an 8,000mAh battery with mid-range Ace series phones

The company’s OnePlus Ace 5 currently offers a massive 6,415mAh battery. It has carbon silicon materials and supports 80W fast charging. The brand’s latest flagship, the OnePlus 13, offers a 6,000mAh battery.
