Smartphones are more powerful today than they ever have been, with some devices offering a better gaming experience than even your desktop computer. On top of that, the mobile gaming platform has expanded so much that the library of games is incredible, so you'll want to use a controller to get the best experience. If you're not tied to a specific ecosystem, the best option for most people is the Razer Raiju Mobile (opens in new tab), which works with both Windows and Android.

Best Overall: Razer Raiju Mobile

The perfect mobile gaming controller

Built-in hair-trigger locks

Four multi-function buttons that can be programmed

Includes short USB-C cable

Works with Android or Windows

Limited to 60 degrees of tilt

Unable to custom map buttons for certain areas

For those who want to get serious about mobile gaming, then you'll have to consider the Razer Raiju Mobile. Instead of a mount that clips onto your existing controller, this is an all-on-one system as Razer has created its own gaming controller.

The controller itself has all of the necessary buttons you would expect, along with a few extras. On the top of the controller, there are two additional trigger buttons for added ergonomics, and under the left and right grip there are multi-function buttons which can be mapped. Best of all, Razer designed this with both Android and Windows in mind, so you can use the Raiju for anything gaming session that arises.

Unlike the mounts that attach to your smartphone, the Raiju limits your viewing angle to 60 degrees. This may be fine for some, but we would have liked a little bit more to suit everyone's potential needs. Another issue is that you are unable to custom map the buttons for certain areas on your screen, meaning you may still have to reach up and tap the screen on your smartphone.

Best for Xbox One Controllers: PowerA Moga Mobile Gaming Clip

PowerA Moga Mobile Gaming Clip

Officially licensed and flexible

Today's Best Deals

Licensed by Xbox

Perfect for use with Project xCloud

Locking articulation points

Fits most smart phones phones

Not compatible with other controllers

A bit pricier than similar options

Whether you are trying to just use your Xbox One controller to play games from the Play Store or using it for Project xCloud, this gaming clip is perfect. The PowerA Moga Mobile Gaming Clip is the only one officially licensed by Microsoft's Xbox brand, setting apart from the rest of the competition.

The clip itself offers various viewing angles, with dual articulation points at the back of the mount and the base of the phone holder. These points can be locked into place, ensuring that your phone won't move itself out of position in a critical moment. Plus, it folds up into a compact package so that you can throw it in your bag for that gaming session later.

As one would expect from an officially-licensed product, you won't be able to use the MOGA Mobile Gaming Clip with any other controllers. That includes any SteelSeries controllers, along with Sony's DualShock 4. While this clip is still affordable, it's a bit pricier than similar options.

Best for DualShock 4 Gamers: PS4 Controller Holder

PS4 Controller Holder

Great for DualShock 4 players

Today's Best Deals

Compatible with many smartphones

Rotates from 0 to 270 degrees

Folds up for added portability

Only one articulating lock

Included Micro-USB cable is outdated

For some, the sleekness of Sony's DualShock 4 can't be understated and is a favorite for gaming sessions. With the included Bluetooth capabilities, that means you can pair your controller to your phone and game from wherever you are. But, you'll need a solid phone mount to do so.

This PS4 Controller Holder is compatible with smartphones measuring as wide as 3.4 inches. Plus, it can rotate from 0 to 270 degrees, allowing you to put your phone in just about any position. Then, you can lock the angle into place, helping to keep your smartphone in place.

We would have liked to see an additional articulating lock, as some of the larger phones could end up tipping back during sessions. The inclusion of a Micro-USB cable is also questionable since many smartphones have made the move to USB-C.

Best for SteelSeries Controllers: SteelSeries SmartGrip

SteelSeries SmartGrip

Great for SteelSeries, but not anything else

Fits all SteelSeries Controllers

Rubber bumpers prevent potential scratching

Adjustable height and angle

Compatible with smartphones up to 6.5-inches

Not compatible with Xbox or PlayStation controllers

Covers On/Off switch on Stratus XL Controller

If you're into the world of third-party controllers, you may have heard of SteelSeries. The company provides quite a few great options in the event that you don't want to use an Xbox or PlayStation controller. Then, you can pair those controllers with the SteelSeries SmartGrip and get a great gaming experience on the go.

In addition to working with your SteelSeries controllers, the company thought about your phone and added a few rubber bumpers. These will help keep your smartphone free from scratches and wear if you play a lot of games. The best part is that you don't have to worry about your smartphone being too big, as it's compatible with devices up to 6.5 inches.

At first glance, you would think that the SmartGrip would work with an Xbox One controller due to the similar designs. That's, unfortunately, not the case since the SmartGrip does not fit over the Xbox One controller properly. Plus, users of the Stratus XL Controller will be frustrated when having to remove the SmartGrip just to power the controller on or off.

Best for Cross Compatibility: Foldable Mobile Phone Clamp Holder

Perfect phone holder for different controllers

Today's Best Deals

Includes thumb stick caps

Works with Xbox One, SteelSeries, and Steam Controllers

Built-in controller stand

Package includes two holders

No articulation locks

Not compatible with DualShock 4

It can be frustrating to be stuck using just a single type of controller when gaming with one of the smartphone holders. This Foldable Phone Clamp Holder removes that frustration in compatibility. That's because you can use this holder with all of the SteelSeries controllers, along with the Xbox One and Steam controllers.

There's a built-in controller stand, so you can prop up your controller on a table. The holder itself works with phones as wide as 3.5 inches, meaning that even the Galaxy Note 10+ can be used with your controller. Plus, you'll get the added benefit of having an additional holder if the first one breaks or gets lost.

Although this phone holder checks many of the boxes for controller compatibility, there's one major option missing — the DualShock 4. You also may need to be a bit careful with the angles of your smartphone, because there are no articulation locks to keep the phone at the right angle.

For ROG Phone II Owners: ASUS ROG Kunai Gamepad

ASUS ROG Kunai Gamepad

Add a controller to the ROG Phone 2

Today's Best Deals

Up to 7 hours of battery life in Wireless Mode

Converts between Gamepad and Handheld modes

Built-in USB-C port

Built-in 3.5mm headphone jack

Uses Bluetooth 4.2

Only works with the ROG Phone II

When the ASUS ROG Phone 2 launched, it was clearly aimed directly at those who wanted a great mobile gaming experience. The only potential problem was that it was quite large and there are times where you would want an actual controller to play.

With the ROG Kunai Gamepad, your ROG Phone 2 is essentially turned into an Android version of the Nintendo Switch. What makes this even better is that you can either use the ROG Kunai as a separate controller, or split up the left and right controller and place the ROG Phone 2 in the middle. There are also built-in USB-C port, 3.5mm headphone jack, and up to seven hours of battery life when using Wireless Mode.

Surprisingly, ASUS opted to only use Bluetooth 4.2, despite the ROG Phone 2 itself being equipped with Bluetooth 5.0. Another downside to this is that you'll only be able to use it with the newer ROG Phone 2, and not even the first iteration, let alone any other smartphones.

Best for Modularity: Razer Junglecat

Razer Junglecat

Impressive controller, if you have the right smartphone

Today's Best Deals

100-hours of battery life

Works with Android or Windows

USB-C Charging

Vast library of compatible games

Must have the "right" smartphone in handheld mode

Not suitable for those with larger hands

The Razer Junglecat is an interesting mobile gaming controller due to the compatibility with both Android and Windows. What makes it interesting is that you can use it with an array of smartphones, but it's not designed for use with all smartphones in handheld mode. That's because the Junglecat is modular, and includes different custom-fit cases to be used with select smartphones.

Razer packed an amazing battery into the Junglecat, providing up to 100 hours of battery life. You can quickly top it off or keep it charged with your favorite USB-C charger. As for compatible games, Razer has quite an impressive list, which continues to expand. Plus, you can retract the two sides of the controller and use it as a Bluetooth controller for your Windows PC.

The downside is that if you want to use the Junglecat in handheld mode, you are limited as to what smartphones can be used. However, if you have a Razer Phone 2, Huawei P30 Pro, Galaxy S10+ or Galaxy Note 9, you'll be fine. The Junglecat also may be a tad bit small for those with larger hands, and you may end up getting some hand cramps over time.

Best for Old School Gamers: 8Bitdo Smartphone Clip for SN30 & SF30 Pro

8Bitdo Smartphone Clip for SN30 & SF30 Pro

Use your old-school controller with your modern smartphone

Today's Best Deals

Works with 8Bitdo SN30 and SF30 Pro

Compatible with smartphones up to 3.6 inches wide

Great design for nostalgia fans

Clip comes in two pieces

No articulation lock

Over the last few years, 8Bitdo has taken the controller market by storm thanks to its line of old-school themed controllers. Many of these, including the SN30 and SF30 Pro, are designed to look just like the classic controllers we grew up with, but with the added benefit of Bluetooth capabilities. Thanks to the Bluetooth onboard, you can use the 8Bitdo controllers with your favorite smartphone, tablet, or computer.

If you already have one of these controllers at your disposal, you can get the 8Bitdo Smartphone Clip, so you can just have an all-in-one gaming experience. This clip is compatible with smartphones up to 3.6-inches wide, making it possible to work with even the larger Android handsets.

On the flip side, the decision to have this clip come in two pieces is an odd one, as it adds a potential stress point if you have a larger smartphone. Another frustration is the lack of an articulation lock, which means that your smartphone could slip out of the perfect angle if used for extended periods of time.

Bottom line

While there are a lot of different options to use your smartphone with your favorite gaming controller, although a lot of them aren't cross platform. You have to figure out which controller you'll likely use with your phone, since a lot of options only work with Xbox controllers, or even SteelSeries controllers. If you can break it down, that can make your choice easy.

For those wanting an all-in-one solution, including the controller, will need to consider the Razer Raiju Mobile (opens in new tab). This includes the controller, along with a built-in expandable clip and programmable multi-function buttons around the controller itself. And if you want to switch over to your PC for some gaming, the Raiju works perfectly with Windows so you won't need multiple controllers for different situations.
