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. As 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, but the Kishi Ultra, much like the Hori Split Pad Pro did for the Nintendo Switch, changed my perspective.

Razer Kishi Ultra – Package Contents

The Razer Kishi Ultra package includes the controller, several sets of rubber cushions (for different devices), stickers, and an instruction manual. At $149.99, the absence of a carrying case or pouch is a notable omission. However, the box and controller packaging maintain Razer's usual high quality.

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

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

Unlike many mobile controllers (especially telescopic ones) which 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 connection boasts superior compatibility. For this review, I tested it on my iPhone 15 Pro, iPhone 14 Plus, and wired on 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, functioned well in NBA 2K25, and offered decent rumble in games like Bakeru.

Razer Kishi Ultra Buttons, D-pad, and Triggers

Before discussing new features, let's assess the controller's feel and performance. My initial concerns about the d-pad proved unfounded; 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, though clicky, have more travel than anticipated.

After extensive use (including several hours-long sessions playing Zenless Zone Zero while charging via passthrough), 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 prolonged use. While I generally dislike Chroma lighting on controllers, I would have preferred a dynamic lighting feature that synced with on-screen gameplay, similar to the Razer Kitsune.

Razer Kishi Ultra – New Features

The 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 provides a full-size feel, resembling a console controller with the phone nestled in the center. While this may not suit those seeking a compact solution, it's not intended to be one. This 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 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 currently exclusive to Android (and Windows for haptics), absent from the iOS version. While I'm less concerned about virtual controller mode, I hope Razer will implement haptics support for iOS in the future.

Razer Kishi Ultra Price Point – Is It Worth It?

For most users, a wireless PS5 or Xbox controller offers a superior and cheaper option for iOS gaming. However, if you prefer a telescopic controller that attaches directly to your phone, the Razer Kishi Ultra's $150 price tag represents a premium offering compared to the $99.99 price point of competitors. The added comfort justifies the extra cost for some, but 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 my long-term experience with Razer's previous controller (review linked), transitioning to the larger Kishi Ultra has been interesting. Like the Hori Split Pad Pro, I find myself preferring 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 bulkier size makes travel inconvenient. Its large size is a concern for transport unless carried in its original box. It's unlikely to replace my Kishi or Backbone One for travel, and I primarily use it at home.

The absence of hall-effect analog sticks at this price point is disappointing. While I haven't experienced drift yet, it's a potential long-term concern.

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

Razer Kishi Ultra 2 Wishlist

For a future iteration, I'd prefer hall-effect analog sticks and smoother edges, particularly around the passthrough charging port. While the L4 and R4 buttons are appreciated, I prefer bottom-mounted paddles for better ergonomics. Adding L5 and R5 paddles with remapping in the Razer Nexus app would be a welcome enhancement. Finally, including a carrying case would significantly improve the package.

Razer Kishi Ultra Review

If you're accustomed to 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 standout features. The lack of full feature support on iOS is a drawback, but overall, it's a significant addition to the mobile controller market. I hope Razer addresses the lack of a carrying case in future revisions.
