OnePlus is preparing to launch a new flagship smartphone, the OnePlus Ace 6 Ultra, focusing heavily on extreme performance and long battery life. This device is expected to feature MediaTek’s latest Dimensity 9500 chipset and a massive battery capacity of up to 9,000mAh, setting a new standard for endurance in flagship devices.
The Dimensity 9500 chipset powers the Ace 6 Ultra with an emphasis on balancing strong CPU and GPU performance alongside efficient power consumption. According to leaks from the well-known tipster Digital Chat Station on Weibo, OnePlus has moved into the engineering phase with this chipset. MediaTek will not release a “Plus” version of this chipset, signaling OnePlus’s plan to fully optimize the standard Dimensity 9500 to directly rival Qualcomm Snapdragon flagship processors.
Advanced Display Features
OnePlus Ace 6 Ultra is rumored to sport a 6.78-inch flat OLED display using LTPS technology. The resolution is set at 1.5K, striking a balance between sharp visuals and power efficiency. What stands out most is the screen’s 165Hz refresh rate, surpassing the more common 120Hz or 144Hz refresh rates in current flagship smartphones. This high refresh rate promises ultra-smooth scrolling, gaming, and user interface navigation.
Innovative Cooling System
To maintain high performance without overheating, OnePlus is reportedly integrating an active cooling system inside the device. This includes an internal fan situated near the camera module, designed to stabilize operating temperatures during demanding tasks such as prolonged gaming sessions. Despite this feature, OnePlus aims to retain a sleek flagship aesthetic and has targeted IP68 certification for dust and water resistance—an impressive feat given the inclusion of air vents for cooling.
Battery Capacity and Security Enhancements
Battery life on the Ace 6 Ultra is expected to be exceptional, with an 8,000mAh battery currently in testing and ambitions to reach 9,000mAh. This would place the device among the smartphones with the highest battery capacities available today, ideal for heavy users who require extended usage without frequent charging. For security, OnePlus plans to install an ultrasonic fingerprint sensor beneath the display, which offers faster and more accurate authentication than optical sensors.
Anticipated Release and Market Impact
The OnePlus Ace 5 Ultra debuted in May 2025, so the Ace 6 Ultra is anticipated to launch around the same period in 2026. Its combination of a 165Hz display, active cooling system, and enormous battery could initiate new trends in the smartphone market. While global release details remain unconfirmed, including availability in Indonesia, the device has already generated excitement among tech enthusiasts. If these specifications hold true, the Ace 6 Ultra could emerge as one of the most compelling “flagship killers” in 2026.
