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 its compatibility extends beyond just phones, making it, to my knowledge, the priciest mobile controller currently available. However, it delivers more than expected, especially for specific devices. A long-time user of the Razer Kishi and Backbone One (including their USB-C iterations), I initially believed a new controller was unnecessary. However, the Razer Kishi Ultra changed my perspective, much like the Hori Split Pad Pro did for the Nintendo Switch a few years ago.

Razer Kishi Ultra – Package Contents

The Razer Kishi Ultra package contained the controller, several sets of rubber cushions (for various devices), stickers, and an instruction manual. Considering its $149.99 price tag, I anticipated a carrying case or at least a protective pouch. That aside, the packaging and the controller's build quality are, as expected from Razer, excellent.

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

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

Unlike many mobile controllers (especially telescopic ones) that only support iPhone and Android, the Razer Kishi Ultra also supports tablets such as the iPad Mini 6th generation. While some recent telescopic controllers offer Bluetooth connectivity, this USB-C controller boasts impressive compatibility. For this review, I tested the Razer Kishi Ultra 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 on my Steam Deck. It was recognized as a generic Xbox gamepad but functioned flawlessly while playing NBA 2K25 on the Steam Deck, and also supported decent 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 had initial concerns about the d-pad, but it performed exceptionally well in games like Garou: Mark of the Wolves ACA NeoGeo, and even newer titles like Hades and Hitman Blood Money Reprisal. Beyond the d-pad, the shoulder buttons and triggers function smoothly, mirroring Razer's previous controllers. The analog sticks are comfortable and responsive, while the face buttons offer a satisfying click, albeit with more travel than anticipated after using the original Razer Kishi.

Overall, 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 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. While I'm not typically a fan of Chroma lighting on controllers, 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 primary appeal lies in its full-size form factor. Unlike Razer's previous offerings or the Backbone One, which feel compact, the Razer Kishi Ultra is full-sized, providing the sensation of holding a high-quality 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, as some prominent titles (like Genshin Impact) lack controller support on mobile outside of iOS.

Beyond the new features, 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), absent from the iOS version. 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 the haptic feedback on the PS5 and HD Rumble on the Switch, and a similar feature on iOS would be a welcome addition.

Razer Kishi Ultra Price Point – Is It Worth It?

I believe most users would benefit from a PS5 or Xbox controller for wireless iOS gaming, offering superior quality at a lower cost. However, if you desire a telescopic controller that attaches to your phone, the most popular options are around $99.99. The Razer Kishi Ultra's $150 price point positions it as a premium controller. Is it worth the extra cost? If you're satisfied with the current pricing of the Razer Kishi and Backbone One, the enhanced comfort justifies the price increase. 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 whether they will experience 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 recommend checking it out. Transitioning from the compact form factor I've grown accustomed to (across Razer and Backbone products) to this larger controller has been interesting. Similar to the Hori Split Pad Pro for the Nintendo Switch, 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 ever used, but its portability is a concern. I worry about its safety in my bag unless I transport it in its original box. I'm unsure if it will replace my Kishi or Backbone One for travel, but I'll primarily use it at home.

At this price point, I had hoped for hall effect analog sticks. I've experienced drift issues with various controllers, and while the Razer Kishi Ultra (and the original Kishi) haven't exhibited this yet, I can't predict its long-term performance. This is a factor to consider before purchasing.

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

Razer Kishi Ultra 2 Wishlist

Regarding potential improvements for a future Razer Kishi Ultra, besides hall effect sticks, I'd like some of the sharper edges (like the passthrough charging port) to be smoother. 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 typically include a protective case. While this controller is not as expensive as a DualSense Edge or Victrix Pro BFG, a case would be a valuable addition 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 the compact buttons and sticks of typical mobile controllers less enjoyable, 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 disappointing, but it's a significant addition to the mobile controller market. I hope Razer continues to improve it while also including a carrying case to protect it during transport.

Razer Kishi Ultra review score: 4.5/5
