Razer Kishi Ultra: Smartphone Gaming's Future

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 a versatile controller, supporting a wide range of devices. While it's the priciest mobile controller I've encountered, its feature set justifies the cost. 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's packaging included the controller, various rubber cushions for different devices (iPhone, iPad Mini 6th gen, Android), stickers, and an instruction manual. At the $149.99 price point, a carrying case or pouch would have been a welcome addition. However, the box and controller packaging are of the high quality expected from Razer.

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) 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 connectivity, the 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 to my iPad Pro. While I didn't test Android or Windows compatibility directly, I did test it wired with my Steam Deck. It registered as a generic Xbox gamepad, but functioned perfectly while playing NBA 2K25 and provided decent rumble in games like Bakeru.

Razer Kishi Ultra Buttons, D-pad, and Triggers

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

After extensive use, including several hours-long gaming sessions (playing Zenless Zone Zero while charging my phone 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 that synced 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 compact designs of previous Razer controllers or the Backbone One, the Kishi Ultra feels like a full-sized console controller with your phone nestled in the center. This might not appeal to those seeking a compact solution, but that's not its intended purpose. 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 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 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 implements haptics support for iOS. The haptic feedback on PS5 and HD Rumble on Switch are features I appreciate, and a similar implementation on iOS would be a welcome addition.

Razer Kishi Ultra Price Point – Is It Worth It?

For most users, a wireless PS5 or Xbox controller offers a superior and cheaper wireless option for iOS. 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 other controllers priced around $100. Is the extra cost justified? If you're satisfied with the Razer Kishi or Backbone One, the added comfort makes the upgrade worthwhile. However, the lack of haptics on iOS diminishes the overall experience compared to Android.

The long-term durability of the joysticks, specifically concerning drift, remains to be seen.

Razer Kishi Ultra – The Best Mobile Controller in 2024?

Compared to Razer's previous, more compact controller (reviewed separately), the transition to the Kishi Ultra's full-size design is significant. Similar to the Hori Split Pad Pro for Switch, I find myself wanting both a full-size and a more compact controller for my iPhone.

The Razer Kishi Ultra offers unparalleled comfort, but its bulkier size makes it less travel-friendly. Its portability is a concern unless carried in its original box. 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 desirable inclusion. I've experienced joystick drift with various controllers, and while the Kishi Ultra hasn't exhibited this issue yet, it's a potential long-term 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 iteration, besides 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 L5 and R5 with remapping in the Razer Nexus app) would enhance the premium feel. Finally, a carrying case would be a valuable addition. High-end console controllers often include such cases, and it would be a worthwhile inclusion for this controller.

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 highlights. The lack of full feature support on iOS is a drawback, but it's a significant addition to the mobile gaming market. I hope Razer continues to improve it, adding a carrying case for better portability.
