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, much like the Hori Split Pad Pro revolutionized the Nintendo Switch experience years ago, completely changed my perspective.
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 were, as expected from Razer, of high quality.
The rubber cushions are paired and clearly labeled: Pair A for iPhone, Pair B for iPad Mini 6th generation, and Pair C for Android. These cushions are unnecessary if you use a phone case.
Razer Kishi Ultra Compatibility – iPhones, Cases, Android, and iPad Mini
Unlike most telescopic mobile controllers (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, this USB-C controller 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. Although I didn't test it on Android or Windows, I did try it wired to my Steam Deck. It was recognized as a generic Xbox gamepad but functioned flawlessly while playing NBA 2K25 on the Steam Deck, and also provided satisfying rumble in games like Bakeru.
Razer Kishi Ultra Buttons, D-pad, and Triggers
Before delving into the new features, let's assess the Razer Kishi Ultra's feel and performance. I initially harbored concerns about the d-pad, but it proved exceptionally responsive in games like Garou: Mark of the Wolves ACA NeoGeo, and even newer titles such as Hades and Hitman Blood Money Reprisal. Beyond the d-pad, the shoulder buttons and triggers functioned flawlessly, mirroring the performance of Razer's earlier controllers. The analog sticks are comfortable and smooth, while the face buttons offer a satisfying click, albeit with more travel distance than anticipated after using the original Razer Kishi.
Overall, after extensive use (including several hours-long gaming sessions playing 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 use. I'm generally 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 primary appeal lies in its full-size form factor. Unlike the compact designs of previous Razer controllers or the Backbone One, the Razer Kishi Ultra's full-size design feels like holding your phone within a high-quality console controller. While this might not appeal to those seeking a compact solution, it's not intended to be one. This full-size design makes it the most comfortable mobile controller I've ever 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, as some notable titles (like Genshin Impact) lack controller support on mobile platforms outside of iOS.
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 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, so a similar feature on iOS would be a welcome addition.
Razer Kishi Ultra Price Point – Is It Worth It?
I believe most users are better off using a PS5 or Xbox controller wirelessly on iOS—a superior and more affordable option. However, if you prefer a telescopic controller that attaches directly to your phone, the most popular options are typically priced at $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 added comfort justifies the price increase. 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 remains to be seen; whether they will suffer from drift over time.
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. Transitioning from the compact form factor I've grown accustomed to over the years (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 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. I'm unsure if the Razer Kishi Ultra will replace my standard Kishi or Backbone One for travel, but I'll definitely only use it at home.
At this price point, I had hoped for hall-effect analog sticks. I've experienced joystick drift with multiple controllers, and while the Razer Kishi Ultra (and the original Kishi) haven't exhibited this issue yet, I can't predict its long-term performance. This is a factor to consider when purchasing.
Having reviewed the Backbone One and Razer Kishi models, I'm eager to try the GameSir lineup, which seems promising. Hopefully, I'll have the opportunity soon.
Razer Kishi Ultra 2 Wishlist
Considering improvements for a future Razer Kishi Ultra, besides hall-effect sticks, I'd like to see some of the sharper edges (like the passthrough charging port) smoothed out. While I appreciate the L4 and R4 buttons, I prefer bottom-mounted paddles for their 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, 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 enhance the package without significantly increasing costs.
Razer Kishi Ultra Review
If you're accustomed to playing with traditional PS5 or Xbox Series controllers (or any full-sized controller) and dislike the compact Joy-Con-sized buttons and sticks typical of mobile controllers, 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 while adding a carrying case to address portability concerns.
