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, featuring customizable analog stick deadzones and more. Since its release, the Razer Kishi Ultra has proven its compatibility extends beyond just smartphones. While it's currently the priciest mobile controller on the market, its feature set justifies the cost for specific 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, but the Razer 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 contains the controller, several sets of rubber cushions for various devices, stickers, and an instruction manual. At $149.99, the absence of a carrying case or pouch is a noticeable omission. However, the box and controller packaging maintain Razer's usual high quality.

The included 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 phone case.

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

Unlike many mobile controllers, particularly telescopic ones, which typically only support iPhones and Android devices, the Razer Kishi Ultra also supports tablets such as 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 to my iPad Pro. Although I didn't test Android or Windows compatibility, I did try it wired to my Steam Deck. It was recognized as a generic Xbox gamepad, functioning well in games like NBA 2K25 and exhibiting decent rumble in titles 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 admirably 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 those on Razer's previous controllers. The analog sticks are comfortable and smooth, while the face buttons, though clicky, have more travel than anticipated compared to 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 regarding 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 typically a fan of Chroma lighting on controllers, and similar to the Razer Kitsune, I would have preferred dynamic lighting synchronized with on-screen gameplay.

Razer Kishi Ultra – New Features

The Razer Kishi Ultra's main attraction is its full-size form factor. Unlike Razer's previous offerings or the Backbone One, it's a full-sized controller, making it feel like you're holding your phone within a high-quality console controller. 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 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.

Additionally, the Razer Kishi Ultra includes 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 virtual controller mode, I hope Razer addresses the lack of haptics on 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 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 option compared to the $99.99 price point of competing controllers. The added comfort justifies the extra cost for some, but the absence of haptics on iOS diminishes the overall experience compared to Android.

Long-term joystick drift remains a potential concern.

Razer Kishi Ultra – The Best Mobile Controller in 2024?

Compared to Razer's previous, more compact controllers, the transition to the full-size Razer Kishi Ultra has been interesting. 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 undoubtedly the most comfortable mobile controller I've used, but its bulkiness makes it less travel-friendly. Its size raises concerns about its safety in my bag unless transported in its original box. It's unlikely to replace my Kishi or Backbone One for travel, but it's my go-to controller for home use.

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

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

Razer Kishi Ultra 2 Wishlist

For a future iteration, aside from hall-effect sticks, I'd prefer smoother edges, particularly around the passthrough charging port. While appreciating the L4 and R4 buttons, 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 enhance the premium feel and protect the investment.

Razer Kishi Ultra Review

For users accustomed to full-sized controllers like those found on PS5 or Xbox Series consoles, and who dislike the compact button and stick layouts of typical mobile controllers, 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 valuable addition to the mobile controller market. Future improvements, including a carrying case, would further enhance its appeal.
