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 and more. Since its release, the Razer Kishi Ultra has proven itself compatible with a wide range of devices, solidifying its position as the priciest mobile controller on the market, but also the most feature-rich. A long-time user of the Razer Kishi and Backbone One, 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's packaging includes the controller, various rubber cushions for different devices (iPhone, iPad Mini 6th gen, Android), stickers, and an instruction manual. At $149.99, the absence of a carrying case or even a protective pouch feels like a missed opportunity. However, the box and controller packaging are, as expected from Razer, high-quality.

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

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

Unlike many mobile controllers, particularly telescopic ones, which typically only support iPhones and Android devices, the Razer Kishi Ultra extends compatibility to tablets like the iPad Mini 6th generation. While some recent telescopic controllers offer Bluetooth connectivity, the Kishi Ultra's USB-C connection seems to offer superior compatibility. For this review, I tested it on 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 on my Steam Deck. It registered as a generic Xbox gamepad but functioned perfectly in games like NBA 2K25 and provided decent rumble feedback in titles such as Bakeru.

Razer Kishi Ultra Buttons, D-pad, and Triggers

Before diving into the new features, let's assess the core functionality. I initially had concerns about the d-pad, but it performed exceptionally well in games ranging from classics like Garou: Mark of the Wolves ACA NeoGeo to modern titles such as Hades and Hitman Blood Money Reprisal. Beyond the d-pad, the shoulder buttons and triggers function flawlessly, mirroring the quality of Razer's previous controllers. The analog sticks are smooth and comfortable, and while the face buttons are clicky, they have a longer travel distance than anticipated.

Overall, after extensive use, including several hours-long gaming sessions (e.g., Zenless Zone Zero while simultaneously charging my phone via passthrough charging), 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 generally indifferent to 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 main selling point is its full-size form factor. Unlike the more compact designs of previous Razer controllers or the Backbone One, the Kishi Ultra offers a full-size feel, resembling a standard console controller with the phone integrated. This might not appeal to users seeking a compact solution, but 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 particularly 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 the virtual controller mode, I hope Razer will implement haptic feedback support for iOS, mirroring the satisfying haptic feedback found on PS5 and HD Rumble on Switch.

Razer Kishi Ultra Price Point – Is It Worth It?

For many, a wireless PS5 or Xbox controller offers a superior and more affordable wireless gaming experience on iOS. However, for those seeking a telescopic controller that directly attaches to their phone, the Razer Kishi Ultra's $150 price tag is significantly higher than the $99.99 price point of competing controllers. Is the extra cost justified? If you're satisfied with the current pricing of the Razer Kishi and Backbone One, the added comfort makes the upgrade worthwhile. However, the lack of haptic feedback on iOS diminishes the overall experience compared to Android.

Long-term joystick drift remains a concern, although it hasn't yet been observed in my testing.

Razer Kishi Ultra – The Best Mobile Controller in 2024?

Compared to Razer's earlier, more compact controllers, the transition to the full-size Kishi Ultra has been significant. Similar to the Hori Split Pad Pro for Switch, I now 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 size makes it less travel-friendly. Its bulkiness raises concerns about its portability unless carried in its original box. It's unlikely to replace my regular Kishi or Backbone One for travel, making it primarily a home-use controller.

The absence of hall-effect analog sticks at this price point is noteworthy. Past experiences with joystick drift on other controllers make this a valid concern, even if it hasn't yet affected the Kishi Ultra.

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

Razer Kishi Ultra 2 Wishlist

For a future iteration, aside from hall-effect sticks, I'd suggest smoothing out some of the sharper edges, particularly around the passthrough charging port. While appreciating the L4 and R4 buttons, I prefer bottom-mounted paddles for better ergonomics. Adding these as options, perhaps with L5 and R5, along with remapping in the Razer Nexus app, would enhance the premium feel. Finally, including a carrying case would elevate the package to a level more consistent with high-end console controllers.

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 standout features. The lack of full feature parity on iOS is a drawback, but overall, it's a significant addition to the mobile controller market. Future improvements, especially the inclusion of a carrying case, would further enhance its appeal.
