OnePlus Ace 7 series revealed with 9,000mAh battery

OnePlus has published key specifications for the Ace 7 series ahead of the phones debut in China later this week, offering a clearer picture of battery, memory and colour options before the formal launch.

Both the Ace 7 and Ace 7 Pro will pack a 9,000mAh Glacier Battery with 100W SuperVOOC fast charging.

Battery, charging and cooling

According to OnePlus China president Li Jie, the Glacier Battery can deliver up to seven hours of gaming at 185fps or 24 hours of continuous video playback. OnePlus says both models include a dedicated battery management chip aimed at maintaining performance at low charge levels and preserving battery health for up to five years.

The phones will support bypass charging, which routes power directly to the device while gaming rather than cycling the battery through repeated charge and discharge. OnePlus presents this as a way to reduce heat generation and improve long-term battery durability. Both models are also listed with an integrated fan-based cooling system that uses dual airflow paths; the company claims this setup can lower temperatures by up to 10 degrees Celsius during extended gaming sessions.

Official store listings in China give a clear view of the memory and colour lineups. The Ace 7 Pro is shown in 12GB+256GB, 16GB+256GB, 12GB+512GB, 16GB+512GB and 16GB+1TB configurations. Its colours are Polar Night Black, Flowing Light White and Pofeng, a light blue finish; the 1TB option appears only in Pofeng. The standard Ace 7 is listed in 12GB+256GB, 16GB+256GB, 12GB+512GB and 16GB+512GB trims, offered in Polar Night Black, Flowing Light White and Cuihuo, a silver-to-orange gradient.

Both phones are expected to use a 6.78-inch 1.5K OLED display with a 185Hz refresh rate. The Ace 7 Pro may add a 200-megapixel main camera and a 50-megapixel periscope telephoto camera with 3.5x optical zoom; the standard Ace 7 may lack the periscope unit. The devices are said to be powered by the Snapdragon 8 Elite Gen 5 V series and Snapdragon 8 Elite Gen 5 chipsets, respectively. For an enhanced gaming experience, both phones are confirmed to feature a dual-airflow cooling system equipped with a built-in fan.
