OnePlus Ace 3 lineup currently consists of two models: the Ace 3 and Ace 3V. However, rumors have been circulating about the addition of a Pro variant, with leaks popping up every now and then. Today, reliable leaker Digital Chat Station (DCS) has shared a new tidbit on the upcoming phone, and it’s a big one – literally.
According to DCS, the OnePlus Ace 3 Pro will have a dual-cell battery with each cell offering 2970mAh capacity, for a combined total of 5940mAh.
However, DCS clarifies that the typical capacity will likely be listed as 6100mAh. That should likely be a marketing decision based on how battery capacity is usually measured in the industry. This would make the Ace 3 Pro the OnePlus phone with the largest battery.

This leak aligns with previous information from DCS, who also hinted at a 1.5K resolution OLED display for the Ace 3 Pro. The powerhouse under the hood is rumored to be the Snapdragon 8 Gen 3 chipset, paired with 16GB of RAM and 1TB of storage. The tipster also hinted at a possible 24GB LPDDR5x RAM variant.
While camera details are uncertain, rumor suggests the same Sony IMX890 50-megapixel primary sensor as the OnePlus Ace 3 / 12R.
Moreover, the Ace 3 Pro is said to have a premium design with metal frames on the side and a glass panel on the back. DCS also tipped at a different design for the phone compared to existing OnePlus flagships.
There’s no definitive timeframe we’ve heard of for Ace 3 Pro’s launch. It’s also uncertain if the company will bring the phone to the global market, even as a re-branded product, since the Ace 2 Pro remained exclusive to China.
