Razer Kishi Ultra: Mobile Gaming Dominator

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 Kishi Ultra has proven its compatibility extends beyond just smartphones, solidifying its position (to my knowledge) as the priciest mobile controller currently available. Despite already owning and regularly using the Razer Kishi and Backbone One (including their USB-C iterations), the Kishi Ultra's features genuinely impressed me, much like the Hori Split Pad Pro did for the Nintendo Switch a few years back.

Razer Kishi Ultra – Package Contents

The Razer Kishi Ultra package included the controller, several sets of rubber cushions for different devices, stickers, and an instruction manual. Given its $149.99 price tag, I had anticipated a carrying case or at least a protective pouch. However, the packaging and the controller's build quality were, as expected from Razer, excellent.

The rubber cushions are paired and clearly labeled: Pair A for iPhone, Pair B for iPad Mini 6th generation, and Pair C for Android devices. These cushions 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 works with tablets like the iPad Mini 6th generation. While some recent telescopic controllers offer Bluetooth connectivity, the Kishi Ultra's USB-C implementation 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 devices, I did try it wired to my Steam Deck. It was recognized as a generic Xbox gamepad and functioned flawlessly while playing NBA 2K25 and exhibited satisfying rumble in games like Bakeru.

Razer Kishi Ultra Buttons, D-pad, and Triggers

Before delving into its new features, let's assess the 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, Hades, and Hitman Blood Money Reprisal. Beyond the d-pad, the shoulder buttons and triggers functioned as smoothly as those on Razer's previous controllers. The analog sticks are comfortable and responsive, and the face buttons are clicky, though with more travel than anticipated compared to the original Razer Kishi.

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

The textured finish, while not rubbery, provides a secure grip and remains comfortable even during extended use. I'm not typically a fan of Chroma lighting on controllers, and similar to the Razer Kitsune, I would have preferred if the lights dynamically reflected the on-screen gameplay.

Razer Kishi Ultra – New Features

The Kishi Ultra's primary appeal lies in its full-size form factor. Unlike the more compact designs of previous Razer controllers or the Backbone One, the Kishi Ultra feels like a full-sized console controller with the phone nestled in the center. While this might not suit users seeking a compact solution, it's not intended to be one. This full-size design makes it the most comfortable mobile controller I've used.

Other notable 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.

Additionally, the 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 currently 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 implement haptics support for iOS devices. I appreciate the haptic feedback on PS5 and HD Rumble on 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 be better served by a PS5 or Xbox controller for wireless play on iOS—a superior and more affordable option. However, if you prefer a telescopic controller that attaches directly to your phone, the Razer Kishi Ultra's $150 price point is a premium compared to other popular options at $99.99. Is the extra cost justified? If you're satisfied with the current pricing of the Razer Kishi and Backbone One, the enhanced comfort makes the upgrade worthwhile. However, the lack of haptics on iOS diminishes the overall experience compared to Android, where you get the full feature set.

The long-term durability of the joysticks (specifically, the 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 recommend checking it out [link to previous review]. Transitioning from the compact form factor I've grown accustomed to with Razer and Backbone products to this larger controller has been an interesting experience. 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 undoubtedly the most comfortable mobile controller I've used, but its portability is a concern. I worry about its safety in my bag unless I transport it in its original box. It's unlikely to replace my standard Kishi or Backbone One for travel, and I primarily use it at home.

At this price point, I had hoped for hall-effect analog sticks. I've experienced joystick drift with various controllers, and while the 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 appears promising. I hope to do so soon.

Razer Kishi Ultra 2 Wishlist

Regarding potential improvements for a future Razer Kishi Ultra, besides hall-effect sticks, I'd appreciate smoother edges, particularly around the passthrough charging port. While I appreciate the L4 and R4 buttons, I prefer the more natural feel of bottom-mounted paddles. Offering these as options, perhaps even adding L5 and R5 with remapping in the Razer Nexus app, would be a valuable enhancement given the premium price. Finally, including a carrying case would be a welcome addition, mirroring the practice of high-end console controllers. While not as expensive as a DualSense Edge or Victrix Pro BFG, a carrying case would be a cost-effective enhancement.

Razer Kishi Ultra Review

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