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. While it's currently the priciest mobile controller on the market, its feature set justifies the cost for many devices. Having extensively used 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, much like the Hori Split Pad Pro's impact on the Nintendo Switch, changed my perspective.

Razer Kishi Ultra – Package Contents

The Razer Kishi Ultra package included the controller, various rubber cushions for different devices (iPhone, iPad Mini 6th generation, Android), stickers, and an instruction manual. Given its $149.99 price tag, the omission of a carrying case or pouch felt like a missed opportunity. 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 – 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 like the iPad Mini 6th generation. While some recent telescopic controllers offer Bluetooth connectivity, the Razer Kishi Ultra's USB-C connection appears to offer superior compatibility. For this review, I tested it on my iPhone 15 Pro, iPhone 14 Plus, and wired on my iPad Pro. While I didn't test Android or Windows compatibility directly, I did try it wired on my Steam Deck. It registered as a generic Xbox gamepad but functioned flawlessly in games like NBA 2K25 and provided satisfying rumble feedback in titles such as Bakeru.

Razer Kishi Ultra Buttons, D-pad, and Triggers

Before diving into the new features, let's assess the controller's feel and performance. My initial concern about the d-pad proved unfounded; it performed exceptionally well in games like Garou: Mark of the Wolves ACA NeoGeo and more modern titles such as Hades and Hitman Blood Money Reprisal. Beyond the d-pad, the shoulder buttons and triggers mirrored the excellent performance of Razer's previous controllers. The analog sticks are comfortable and smooth, while the face buttons offer a satisfying click, albeit with more travel distance than anticipated from the original Razer Kishi.

After extensive use, including several hours-long gaming sessions (Zenless Zone Zero, while simultaneously charging my phone via passthrough charging), 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 play sessions. While I'm not a fan of Chroma lighting on controllers, and similar to the Razer Kitsune, I would have preferred dynamic lighting that synced with 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 Kishi Ultra provides a full-sized feel, resembling a console controller with the phone nestled in the center. This might not appeal to those seeking a compact solution, but it's not designed for that purpose. This 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 particularly 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 iOS Limitations – 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 find a way to enable haptics on iOS devices. 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 more affordable wireless gaming experience on iOS. However, if you prefer a telescopic controller that directly attaches to your phone, the Razer Kishi Ultra's $150 price point represents a premium offering, significantly higher than the $99.99 price point of popular competitors. Is the extra cost justified? If you're satisfied with the Razer Kishi or Backbone One, the added comfort makes the upgrade worthwhile. However, the lack of haptics on iOS diminishes the overall experience compared to Android.

Long-term joystick drift remains a potential concern, although I haven't experienced it yet.

Razer Kishi Ultra – The Best Mobile Controller in 2024?

Compared to my long-term experience with Razer's previous controller (review linked here), transitioning to this full-size controller has been an interesting experience. Similar to the Hori Split Pad Pro for the Switch, I find myself wanting both a full-size and a more compact controller for my iPhone.

The Razer Kishi Ultra offers unparalleled comfort, but its bulkier size makes it less travel-friendly. Its size raises concerns about its portability unless carried in its original box. I'm unlikely to replace my Kishi or Backbone One for travel, reserving the Ultra for home use.

The lack of hall-effect analog sticks at this price point is a notable omission. I've encountered drift issues with various controllers, and while the Razer Kishi Ultra hasn't exhibited this yet, it's a factor to consider.

Having reviewed Backbone One and Razer Kishi models, I'm eager to explore GameSir's offerings, which appear promising.

Razer Kishi Ultra 2 Wishlist

For a future Razer Kishi Ultra iteration, beyond hall-effect sticks, I'd suggest smoothing out some of the sharper edges, particularly around the passthrough charging port. While I appreciate the L4 and R4 buttons, I prefer bottom-mounted paddles for a more natural feel. Adding these as options, perhaps with L5 and R5 and remapping capabilities within the Razer Nexus app, would enhance the premium experience. Finally, including a carrying case would significantly improve the overall package.

Razer Kishi Ultra Review Summary

If you prefer the feel of traditional PS5 or Xbox controllers and find compact mobile controller designs uncomfortable, the Razer Kishi Ultra is ideal. Its comfortable grip, excellent d-pad, and face buttons are major highlights. The lack of full feature support on iOS is a drawback, but it's a significant addition to the mobile controller market. I hope Razer addresses this and includes a carrying case in future iterations.
