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 smartphones. While undeniably the priciest mobile controller on the market (to my knowledge), it justifies its cost with a surprising array of features. 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 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 package contains the controller, several sets of rubber cushions for different devices, a sticker sheet, and an instruction manual. Given the $149.99 price tag, I had anticipated a carrying case or at least a protective pouch. 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 you use a phone case.

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

Unlike many mobile controllers, particularly telescopic ones, which typically support only 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 to my iPad Pro. Although I didn't test it on Android or Windows, I did try it wired to my Steam Deck. It registered as a generic Xbox gamepad but functioned flawlessly while playing NBA 2K25 on the Steam Deck. It also delivered satisfying rumble in games like Bakeru.

Razer Kishi Ultra Buttons, D-pad, and Triggers

Before discussing its new features, let's assess the Razer Kishi Ultra's feel and performance. I initially harbored concerns about the d-pad, but it performed admirably in games such as Garou: Mark of the Wolves ACA NeoGeo and more recent titles like Hades and Hitman Blood Money Reprisal. Beyond the d-pad, 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 provide a satisfying click, albeit with more travel than anticipated after using the original Razer Kishi.

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

The textured finish, while not rubbery, provides excellent grip and remains comfortable even during extended use. I'm not a fan of 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 main attraction is its full-size form factor. Unlike the compact designs of previous Razer controllers or the Backbone One, the Razer Kishi Ultra offers a full-size feel, making it incredibly comfortable to hold. This might not appeal to users 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 (for 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, passthrough charging (15W), and L4 and R4 shoulder buttons.

Razer Kishi Ultra Features Missing on iOS – 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 not overly concerned about the virtual controller mode, I hope Razer will find a way to enable haptics on iOS devices. I appreciate haptic feedback on the PS5 and HD Rumble on the Switch, and a similar feature on iOS would be welcome.

Razer Kishi Ultra Price Point – Is It Worth It?

I believe most users are better off with a PS5 or Xbox controller for wireless play on iOS—a superior and more affordable option. If you prefer a telescopic controller that attaches to your phone, the most popular options are around $99.99, making the Razer Kishi Ultra's $150 price point significantly higher. Is it worth the extra cost? If you're satisfied with the Razer Kishi and Backbone One's price points, the added comfort justifies the upgrade. However, the lack of haptics on iOS diminishes the experience compared to Android, where you get the full feature set.

The long-term durability of the joysticks and 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 encourage you to do so. Transitioning from the compact form factor I've grown accustomed to with Razer and Backbone products to this larger controller has been interesting. Similar to the Hori Split Pad Pro for the Nintendo Switch, I now find myself wanting 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 bulkiness makes it less travel-friendly. I'm concerned about its portability unless I transport it in its original box. I doubt it will replace my regular Kishi or Backbone One for travel, and I primarily use it at home.

At this price, I had hoped for hall effect analog sticks. I've experienced joystick drift with multiple controllers, and while the Razer Kishi Ultra hasn't exhibited this issue yet (nor has the original Kishi), I can't predict its long-term performance. This is a factor to consider before purchasing.

Having reviewed Backbone One and Razer Kishi models, I'm eager to explore the GameSir lineup, which seems promising. Hopefully, I'll have the opportunity to do so soon.

Razer Kishi Ultra 2 Wishlist

For a future Razer Kishi Ultra iteration, aside from hall effect sticks, I'd like to see some of the sharper edges, such as the passthrough charging port, smoothed out. While I appreciate the L4 and R4 buttons, I prefer bottom-mounted paddles for a more natural feel. Offering these as options, given the premium price, would be beneficial. Perhaps even L5 and R5 paddles with remapping in the Razer Nexus app. Finally, a carrying case would be a welcome addition. High-end console controllers usually include a protective case, and while the Razer Kishi Ultra isn't as expensive as a DualSense Edge or Victrix Pro BFG, a case would enhance the package without significantly increasing the cost.

Razer Kishi Ultra Review

If you're accustomed to playing with full-sized controllers like the PS5 or Xbox Series controllers and find compact mobile controller buttons and sticks less satisfying, the Razer Kishi Ultra is ideal. Its comfortable grip, excellent d-pad, and face buttons make it a standout. The lack of full feature support on iOS is disappointing, but it's a significant addition to the mobile controller market. I hope Razer continues to improve upon this design and includes a carrying case for better portability.
