Is the Serafim S3 cloud gaming controller suitable? iPhone and Android mobile controller review! We’ll tell you the pros and cons!
As phones like the iPhone and Android continue to improve their hardware specs, graphically demanding mobile games, such as Genshin Impact and Zenless Zone Zero, are growing in popularity. Many of these games now support gamepad operation, breaking away from the traditional mobile game focus on touch controls.
However, mobile devices differ from PCs, Switch, and other consoles, emphasizing portability and convenience. When pairing with a game console’s Bluetooth controller, there may be issues like no phone stand or inconvenient gameplay. This article will unbox a controller specifically for mobile devices—the Serafim S3 Cloud Gaming Controller. We will evaluate the accuracy of the joystick and control buttons and analyze the pros and cons for players to consider.

Unboxing the Serafim S3 Cloud Gaming Controller

The Serafim S3 Cloud Gaming Controller (the Serafim S3) is a gamepad designed primarily for Android mobile devices, with iOS support starting in 2024. Since it’s different from a PC controller, I will adjust my review to focus more on the mobile experience. This article will introduce the design and then slowly transition to performance tests.

Packaging Design

The Serafim S3 packaging consists of two layers. The top layer is a white outer box with a front illustration of the controller and a purple ink background. It has an apparent visual theme. The back features key specifications and highlights

The inner part uses a black cardboard box, with the controller fixed securely in a plastic template. The analog sticks are protected by circular foam pads, making them safe for transportation.

Contents & Accessories

Inside the package, you’ll find three main parts: the controller, interchangeable grips, and a manual. One feature worth mentioning is that the Serafim S3 allows users to swap out the grips based on preference. It comes with a thick grip and a thin grip. The thick grip has an anti-slip surface, providing a more secure hold. The thin grip, while less slip-resistant, feels smoother and is thinner.

Design: Weight & Dimensions

The Serafim S3 is designed specifically for mobile use. It is similar in appearance to handheld consoles like the Switch or Steam Deck. However, it features a phone stand in the middle instead of a built-in screen. The Serafim S3 measures about 26 x 9.4 x 3.4 cm when not connected to a phone. The adjustable phone stand can hold up to 17.9 cm long, fitting models like the iPhone 15 Pro Max and Galaxy S24 Ultra.

In terms of weight, the Serafim S3, without a phone installed, weighs approximately 146.5g. The average phone weight ranges between 160g and 200g, depending on its size. The total handheld weight could range from about 300g to 350g, lighter than the Nintendo Switch (about 420g, including Joy-Cons) or the Steam Deck (around 669g), making it less of a burden.

Buttons & Features

The Serafim S3 controller surface uses a carbon fiber pattern for visual and tactile effects. In terms of functionality, the button layout includes standard joysticks, a D-pad, ABXY buttons, and RL triggers. Additionally, there are special function keys for screenshots and recording videos, catering to everyday mobile game needs.

Performance Testing

For testing, I will focus on six main areas: joysticks, ABXY buttons, triggers, phone stand, USB-C port, and the dedicated app. Testing includes feel, accuracy, joystick drift, and additional features.

▼ The joystick positions on the Serafim S3 (upper left and lower right) are similar to the design of an Xbox controller

Analog Stick Performance

Analog sticks are a critical component of controller-based gaming. The Serafim S3 uses electromagnetic sensors to ensure no drift and smooth operation. The precision and responsiveness were accurate through testing, though the range is slightly smaller compared to high-end controllers.

ABXY Buttons & Triggers

The buttons are smaller and have a shorter travel distance, making them feel flat. The triggers, particularly LT and RT, could use more gradual pressure feedback. This design may be limiting for gamers who enjoy racing games.

Phone Stand & USB-C Connectivity

The stand can hold phones with cases up to 3mm thick, though more prominent cases might affect connectivity. The controller also features a 3.5mm headphone jack and supports charging while playing via USB-C.
