TouchArcade Rating: Back in April, the Razer Nexus (Free) app received an update adding support for the then-unannounced Razer Kishi Ultra controller. This controller boasts features like customizable analog stick deadzones and more. Since its release, the Razer Kishi Ultra has proven its compatibility extends beyond just phones. While it's currently the priciest mobile controller on the market, its feature set justifies the cost for specific devices. Having extensively used the Razer Kishi and Backbone One (including their USB-C iterations), I initially felt no need for a new controller. However, the Razer Kishi Ultra proved to be a game-changer, much like the Hori Split Pad Pro did for the Nintendo Switch.

Razer Kishi Ultra – Package Contents

The Razer Kishi Ultra's packaging includes the controller, various rubber cushions for different devices (iPhone, iPad Mini 6th gen, Android), stickers, and an instruction manual. Given the $149.99 price tag, a carrying case or pouch would have been a welcome addition. However, the box and controller packaging maintain Razer's usual high quality.

The rubber cushions are paired and clearly labeled for iPhone (Pair A), iPad Mini 6th generation (Pair B), and Android (Pair C). These are unnecessary if you use a phone case.

Razer Kishi Ultra Compatibility – iPhone, Cases, Android, and iPad Mini

Unlike many mobile controllers, especially telescopic ones, which typically only support iPhones and Android devices, the Razer Kishi Ultra also supports tablets like the iPad Mini 6th generation. While some recent telescopic controllers offer Bluetooth connectivity, the Razer Kishi Ultra's USB-C connection seems to offer superior compatibility. For this review, I tested it with my iPhone 15 Pro, iPhone 14 Plus, and wired to my iPad Pro. While I didn't test Android or Windows compatibility directly, I did test it wired to my Steam Deck. It was recognized as a generic Xbox gamepad and functioned flawlessly in games like NBA 2K25, also exhibiting decent rumble in titles like Bakeru.

Razer Kishi Ultra Buttons, D-pad, and Triggers

Before discussing new features, let's assess the controller's feel and performance. I initially had concerns about the d-pad, but it performed exceptionally well in games like Garou: Mark of the Wolves ACA NeoGeo, Hades, and Hitman Blood Money Reprisal. Beyond the d-pad, the shoulder buttons and triggers function as smoothly as those on Razer's previous controllers. The analog sticks are comfortable and responsive, while the face buttons provide satisfying clicks, albeit with slightly more travel than expected compared to the original Razer Kishi.

Overall, I have no complaints about the Razer Kishi Ultra's d-pad, buttons, or triggers after extensive use, including several hours-long gaming sessions (e.g., Zenless Zone Zero) while simultaneously charging my phone via passthrough charging.

The textured finish, while not rubbery, provides excellent grip and remains comfortable even during extended use. While I'm not a fan of Chroma lighting on controllers, I would have preferred the lights to dynamically reflect on-screen gameplay, similar to the Razer Kitsune.

Razer Kishi Ultra – New Features

The Razer Kishi Ultra's primary appeal lies in its full-size form factor. Unlike the compact designs of previous Razer controllers or the Backbone One, the Razer Kishi Ultra provides a full-size feel, resembling a standard console controller with the phone nestled in the center. This might not appeal to those seeking a compact solution, but it's not designed to be one. The full-size design makes it the most comfortable mobile controller I've used.

Other notable features include Chroma customization via the app, haptics (Android and Windows), and virtual controller mode (Android only). The virtual controller mode is beneficial for Android games that lack controller support on iOS, such as Genshin Impact.

Additional features include a 3.5mm headphone jack, 15W passthrough charging, and L4 and R4 shoulder buttons.

Razer Kishi Ultra iOS Limitations – Haptics and Virtual Controller Mode

Haptics and virtual controller mode are currently exclusive to Android (and Windows for haptics) and unavailable on iOS. While I'm less concerned about the virtual controller mode, I hope Razer will implement haptics support for iOS devices. The haptic feedback found in PS5 and Switch controllers is a feature I appreciate, and its inclusion on iOS would enhance the experience.

Razer Kishi Ultra Pricing – Is It Worth It?

For many, a PS5 or Xbox controller offers a superior and more affordable wireless gaming solution on iOS. However, if you prefer a telescopic controller that attaches directly to your phone, the Razer Kishi Ultra's $150 price point is significantly higher than the $99.99 price point of competing options. Is the extra cost justified? If you're satisfied with the Razer Kishi or Backbone One, the upgrade is worthwhile for the enhanced comfort. However, the lack of haptics on iOS diminishes the overall experience compared to Android.

Long-term joystick drift remains a concern, although I haven't experienced it yet.

Razer Kishi Ultra – The Best Mobile Controller in 2024?

Compared to Razer's earlier, more compact controllers, the shift to the full-size Razer Kishi Ultra is significant. Similar to the Hori Split Pad Pro, I now find myself preferring both a full-size and a more compact controller for my iPhone.

The Razer Kishi Ultra is undoubtedly the most comfortable mobile controller I've used, but its bulkier size makes it less travel-friendly. I'm concerned about its portability unless I use the original box for transport. It's unlikely to replace my Kishi or Backbone One for travel, making it primarily a home-use controller.

At this price point, hall-effect analog sticks would have been a welcome addition. I've experienced drift issues with other controllers, and while the Razer Kishi Ultra hasn't exhibited this yet, it remains a potential concern.

Having reviewed Backbone One and Razer Kishi models, I'm eager to explore the GameSir lineup.

Razer Kishi Ultra 2 Wishlist

For a future Razer Kishi Ultra iteration, hall-effect sticks are a top priority. I'd also appreciate smoother edges around elements like the passthrough charging port. While the L4 and R4 buttons are useful, I prefer bottom-mounted paddles for better ergonomics. Including these as options, perhaps with L5 and R5 paddles and remapping in the Razer Nexus app, would be a significant improvement. Finally, a carrying case would greatly enhance the overall package.

Razer Kishi Ultra Review Summary

If you prefer the feel of full-size controllers like those found on PS5 or Xbox Series consoles and find compact mobile controllers uncomfortable, the Razer Kishi Ultra is ideal. Its comfortable grip, excellent d-pad, and responsive face buttons make it a standout. The lack of full feature parity on iOS is a drawback, but overall, it's a significant contribution to the mobile gaming controller market. A carrying case would be a valuable addition in future iterations.
