OnePlus is making a play for mobile gamers with the Strix G15, a snap-on controller shell that wraps around the new Ace 6 Ultra and transforms it into something resembling a dedicated handheld console. The controller, which launched on 2026-04-28 alongside the phone in China, connects directly via USB-C and ditches the joysticks and face buttons entirely in favor of physical shoulder triggers and secondary bumpers, a design clearly optimized for competitive mobile shooters rather than general-purpose gamepad use.
The Strix G15's triggers are rated at 1.8ms response time with a 1,000Hz polling rate, putting them in line with what you would expect from a serious PC gaming peripheral rather than a phone accessory. Ergonomic grips position the triggers naturally under one's index fingers, while the secondary buttons sit just above. A pass-through USB-C port on the bottom means charging mid-session is not an issue, and a dedicated cutout accommodates OnePlus's magnetic cooler accessory for sustained performance under load.
The phone powering it all is no slouch either. The Ace 6 Ultra runs MediaTek's Dimensity 9500 paired with a 17.2 cm (6.78-inch) 1.5K OLED display at 165Hz, an 8,600 mAh battery with 120W charging, and ships with Android 16. The Mali-G1-Ultra GPU should handle demanding titles without thermal throttling, especially with the optional active cooling attachment.
The Strix G15 is available in China for $65 (€60), with no international availability announced yet. It is a deliberately focused accessory, one that bets mobile gaming's future lies in trigger-based shooters rather than trying to replicate a full gamepad experience.
