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

TouchArcade Rating: This April, the Razer Nexus app (free on iOS and Android) gained 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 the priciest mobile controller I've encountered, its feature set justifies the cost for compatible devices. A long-time user of 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, much like the Hori Split Pad Pro did for the Nintendo Switch, significantly altered my perspective.

Razer Kishi Ultra – Package Contents

The Razer Kishi Ultra packaging contained the controller, several sets of rubber cushions (for different devices), stickers, and an instruction manual. Given its $149.99 price tag, I anticipated a carrying case or at least a protective pouch. However, the box and controller packaging are, as expected from Razer, of high quality.

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

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

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

Razer Kishi Ultra Buttons, D-pad, and Triggers

Before exploring its new features, let's assess the controller's feel and performance. I initially had reservations 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, and the face buttons offer a satisfying click, though with more travel than anticipated compared to the original Razer Kishi.

After extensive use (including several hours-long gaming sessions with Zenless Zone Zero while simultaneously charging my phone via passthrough charging), I have no complaints regarding the d-pad, buttons, or triggers.

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

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 Kishi Ultra feels like a full-sized console controller with the phone nestled in the center. 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.

Additional 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.

Beyond these new features, the Razer Kishi Ultra includes a 3.5mm headphone jack, passthrough charging (15W), and L4 and R4 shoulder buttons.

Razer Kishi Ultra iOS Limitations – Haptics and Virtual Controller Mode

Haptics and virtual controller mode are 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. I appreciate the haptic feedback on the PS5 and HD Rumble on the Switch, and a similar feature on iOS would be a welcome addition.

Razer Kishi Ultra Price Point – Is It Worth It?

For most users, a PS5 or Xbox controller offers a superior and more affordable wireless solution for iOS. If you prefer a telescopic controller that directly attaches to your phone, the leading alternatives are priced around $99.99. The Razer Kishi Ultra's $150 price point positions it as a premium controller. Is the extra cost justified? If you're content with the pricing of the Razer Kishi and Backbone One, the added comfort makes the extra expense worthwhile. However, the absence of haptics on iOS diminishes the overall experience compared to Android, where it offers full functionality.

The long-term durability of the joysticks (specifically, the potential for drift) remains to be seen.

Razer Kishi Ultra – The Best Mobile Controller in 2024?

If you haven't read my review of Razer's previous controller, I recommend doing so. Transitioning from the compact form factor of previous Razer and Backbone controllers to this larger design has been an interesting experience. Similar to the Hori Split Pad Pro for the Nintendo Switch, I find myself wanting 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 portability is a concern. I worry about its safety in my bag unless I use the original packaging. It's unlikely to replace my standard Kishi or Backbone One for travel; I'll primarily use it at home.

At this price point, I had hoped for hall-effect analog sticks. I've experienced joystick drift with several controllers, and while it hasn't occurred with the Razer Kishi Ultra (or the original Kishi) yet, it's a potential long-term issue to consider.

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

Razer Kishi Ultra 2 Wishlist

For a future Razer Kishi Ultra iteration, aside from hall-effect sticks, I'd prefer smoother edges around elements like the passthrough charging port. While I appreciate the L4 and R4 buttons, I prefer bottom-mounted paddles for a more natural feel. Including these as options (perhaps even L5 and R5 with remapping) would enhance the premium feel. Finally, a carrying case would be a welcome addition, mirroring the practice of including high-quality cases with premium console controllers. While not as expensive as a DualSense Edge or Victrix Pro BFG, a carrying case would be a valuable inclusion.

Razer Kishi Ultra Review

If you're accustomed to full-sized controllers like those found on PS5 or Xbox Series consoles and prefer them over the compact designs typical of mobile controllers, the Razer Kishi Ultra is ideal. Its comfortable grip, excellent d-pad, and face buttons are highlights. The lack of full feature parity on iOS is disappointing, but this controller is a significant addition to the mobile gaming market. I hope Razer continues to improve upon this design and includes a carrying case in future iterations.
