OnePlus is gearing up to launch the Ace 3 Pro, and leaks are spilling the beans on its battery capacity and memory options.

Digital Chat Station reveals that OnePlus has developed a new battery technology that packs more power into a slimmer profile. This innovation will debut in the Ace 3 Pro and will be integrated into future flagships like the OnePlus 13.

Color options for the new Ace will include at least Black, a Green leather option, and a special “Collector’s Edition” in Ceramic White.

Images shared by DCS compare the current 5,000mAh battery (found in the OnePlus Ace 2/11R) with a thickness of 6mm to the new 6,100mAh package measuring a mere 5.51mm. This new battery design is expected to be suitable for various devices with flat or curved displays and backs.

It’s speculated that this could be the “Glacier Battery” co-developed by OnePlus and CATL, which was recently unveiled.

On the memory front, the OnePlus Ace 3 Pro is rumored to offer options with 16GB RAM + 512GB storage or a whopping 24GB RAM + 1TB storage. DCS also suggests a potential 12GB RAM + 256GB storage variant at a more affordable price point of CNY2,999 (around $415), but this remains unconfirmed by OnePlus.
