Razer Kishi Ultra Mobile Controller Review – The Best Mobile Controller in 2024?

TouchArcade Rating: This April, the Razer Nexus app (free on iOS and Android) gained 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 delivers unexpected features 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. However, the Razer Kishi Ultra proved a game-changer, much like the Hori Split Pad Pro did for the Nintendo Switch years ago.

Razer Kishi Ultra – Package Contents

The Razer Kishi Ultra box contained the controller, several sets of rubber cushions (for different devices), stickers, and an instruction manual. Given its $149.99 price tag, I anticipated a carrying case or at least a protective pouch. However, the box and controller packaging maintained Razer's usual high quality.

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 most telescopic mobile controllers (which typically only support iPhone and Android), the Razer Kishi Ultra also accommodates tablets like the iPad Mini 6th generation. Recent telescopic controllers have incorporated Bluetooth, but this USB-C model boasts superior compatibility. For this review, I tested the Razer Kishi Ultra with my iPhone 15 Pro, iPhone 14 Plus, and wired to my iPad Pro. While I didn't test it with Android or Windows devices, 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, also exhibiting decent rumble in games like Bakeru.

Razer Kishi Ultra Buttons, D-pad, and Triggers

Before discussing new features, let's assess the Razer Kishi Ultra's feel and performance. I initially harbored concerns about the d-pad, but it performed exceptionally well in games like Garou: Mark of the Wolves ACA NeoGeo and newer titles such as Hades and Hitman Blood Money Reprisal. Beyond the d-pad, the shoulder buttons and triggers function as smoothly as on Razer's previous controllers. The analog sticks are comfortable and responsive, while the face buttons provide satisfying clicks, 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 selling point 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, resembling a high-quality console controller with the phone nestled in the center. This might not appeal to those seeking a compact solution, but it’s not intended to be one. 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 on iOS, such as Genshin Impact.

Beyond these 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) and unavailable on iOS. While I'm less 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?

For most users, a wireless PS5 or Xbox controller offers a superior and cheaper wireless gaming experience on iOS. If you prefer a telescopic controller that attaches directly to your phone, popular alternatives cost around $99.99. Therefore, the Razer Kishi Ultra's $150 price tag positions it as a premium controller. Is it worth the extra cost? If you're satisfied with the Razer Kishi and Backbone One's price points, the enhanced comfort justifies the upgrade. However, the lack of haptics on iOS diminishes the overall experience compared to Android, where all features are available.

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

Razer Kishi Ultra – The Best Mobile Controller in 2024?

If you haven't read my review of Razer's previous controller, you can find it [here](insert link if available). Transitioning from the compact form factor I've grown accustomed to (across Razer and Backbone products) to this larger design has been an interesting experience. 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 used, but its portability is a concern. I worry about its safety in my bag unless transported in its original box. I'm unsure if it will replace my standard Kishi or Backbone One for travel, but it's primarily used at home.

At its price point, I had hoped for hall-effect analog sticks. I've encountered drift issues with various controllers, and while the Razer Kishi Ultra (and the original Kishi) haven't exhibited this yet, it's a potential long-term concern.

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

Razer Kishi Ultra 2 Wishlist

For a future Razer Kishi Ultra iteration, besides hall-effect sticks, I'd like smoother edges around features like the passthrough charging port. While I appreciate the L4 and R4 buttons, I prefer bottom-mounted paddles for a more natural feel. Offering these as options (perhaps L5 and R5 with remapping in the Razer Nexus app) would be a worthwhile addition given the premium price. Finally, including a carrying case would be a welcome enhancement, mirroring the practice of high-end console controllers. Although less expensive than a DualSense Edge or Victrix Pro BFG, a carrying case would be a valuable addition.

Razer Kishi Ultra Review

If you're accustomed to full-size controllers like the PS5 or Xbox Series controllers and find compact mobile controller buttons and sticks 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 disappointing, but it's a significant addition to the mobile controller market. I hope Razer continues to improve it, including a carrying case to protect it during transport.

Razer Kishi Ultra Review Score: 4.5/5
