OnePlus' gaming controller for smartphones features an impressive charging trick that you're sure to appreciate.

      The new add-on does more than just add buttons; it could significantly improve the charging and cooling experience during extended gaming sessions on your phone.

      OnePlus’ new controller for the Ace 6 Ultra appears to be another effort to transform a phone into a handheld device, but the more innovative aspect is the open space in the center. According to OnePlus, this area is designed for cooling, and promotional images indicate that this is not merely a grip with triggers attached. The design aims to facilitate heat management while providing easier power options.

      OnePlus emphasizes its gaming features, which include four physical buttons, a combination of touch-and-button controls, micro-switch inputs, a 1 kHz polling rate, and a claimed 1.8 ms response time. However, the real selling point is long-term comfort, particularly for shooter games that can be punishing with uncomfortable hand positions and hot devices.

      Importance of the center gap

      The center gap is where the design concept truly becomes clear. OnePlus’ promotional visuals suggest potential support for a magnetic cooling accessory, while the USB-C port at the bottom is strategically placed to allow charging while playing, without obstructing your hands. The curved grips further enhance the feeling that this is meant to resemble a handheld rather than just a basic phone attachment.

      Accessories for phone gaming tend to involve compromises. A charger might protrude, a cooler could hinder gameplay, or overall usability diminishes after a short period. OnePlus seems to be attempting to circumvent these issues, although confirmation of compatibility with specific OnePlus or Oppo wireless charging pads is still pending.

      Focus on comfort rather than specifications

      OnePlus is positioning this as a serious accessory for shooter games. Their promotional materials highlight features like custom button mapping, combined touch-and-button inputs, and a built-in gaming antenna for improved signal strength.

      Consequently, the layout is more significant than the raw specifications. Optimized input speed looks appealing on advertisements, but issues like heat buildup, battery depletion, and cable placement are the usual culprits that compromise extended gameplay.

      The key question ahead of the launch

      Currently, the controller is only announced for launch in China on April 28, 2026, with no confirmed global release date. OnePlus has also indicated that the controller will be sold separately, with more details to follow in official announcements.

      If OnePlus affirms compatibility with its or Oppo’s fan-equipped wireless charging options, this could prove to be a genuinely innovative phone gaming accessory. If not, it remains a well-considered controller, albeit lacking a more distinctive reason for interest.
