Razer Kishi Ultra Mobile Controller Review – The Best Mobile Controller in 2024?

TouchArcade Rating: This 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. 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 certain 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 a game-changer, much like the Hori Split Pad Pro did for the Nintendo Switch.

Razer Kishi Ultra – Package Contents

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

The rubber cushions are paired and clearly marked 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) that 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, the Kishi Ultra's USB-C connectivity boasts 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, I did try it wired on my Steam Deck. It was recognized as a generic Xbox gamepad, but functioned perfectly in games like NBA 2K25 and Bakeru (demonstrating good rumble support).

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. The shoulder buttons and triggers function flawlessly, mirroring Razer's previous controllers. The analog sticks are comfortable and smooth, while the face buttons offer a satisfying click, albeit with more travel than anticipated after using the original Razer Kishi.

After extensive use, including several hours-long gaming sessions (e.g., Zenless Zone Zero while charging via passthrough), I have no complaints about the d-pad, buttons, or triggers.

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 dynamic lighting synchronization with on-screen gameplay, similar to the Razer Kitsune.

Razer Kishi Ultra – New Features

The Razer Kishi Ultra's primary appeal is its full-size form factor. Unlike the compact designs of previous Razer controllers or the Backbone One, the Kishi Ultra offers a full-size feel, placing your phone centrally within a high-quality console controller. This might not appeal to those seeking a compact solution, but it's not intended to be one. The full-size design makes it the most comfortable mobile controller I've used.

Other 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 outside of iOS.

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). While I'm less concerned about the virtual controller mode, I hope Razer will implement haptics support for iOS. The haptic feedback on PS5 and HD Rumble on Switch are highly valued, and a similar feature on iOS would be a significant improvement.

Razer Kishi Ultra Price Point – Is It Worth It?

For most users, a wireless PS5 or Xbox controller offers a superior and cheaper wireless gaming experience on iOS. However, if you prefer a telescopic controller that attaches directly to your phone, the Razer Kishi Ultra's $150 price point represents a premium option compared to other popular controllers priced around $99.99. Is the extra cost justified? If you're satisfied with the Razer Kishi or Backbone One, the extra comfort makes it worthwhile. However, the lack of haptics on iOS diminishes the overall experience compared to Android.

Long-term joystick drift remains a concern.

Razer Kishi Ultra – The Best Mobile Controller in 2024?

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

The Razer Kishi Ultra is undeniably the most comfortable mobile controller I've used, but its portability is a concern. Its size makes it unwieldy for travel unless carried in its original box. It's unlikely to replace my Kishi or Backbone One for travel, but it's perfect for home use.

The lack of hall-effect analog sticks at this price point is disappointing. While I haven't experienced drift yet, it's a potential issue to consider.

I intend to review GameSir controllers in the future, as they seem promising.

Razer Kishi Ultra 2 Wishlist

For a future Razer Kishi Ultra iteration, I'd prioritize hall-effect analog sticks and smoother edges around the passthrough charging port. While the L4 and R4 buttons are useful, I prefer bottom-mounted paddles for better ergonomics. Adding L5 and R5 paddles with remapping capabilities in the Razer Nexus app would be a significant improvement. Finally, including a carrying case would elevate the overall package.

Razer Kishi Ultra Review

If you prefer the feel of full-sized controllers like the PS5 or Xbox controllers and find compact mobile controllers uncomfortable, the Razer Kishi Ultra is ideal. Its comfortable grip, excellent d-pad, and face buttons are its strengths. The lack of full feature support on iOS is a drawback, but it's a significant addition to the mobile controller market. The addition of a carrying case would greatly enhance its practicality.
