Mygeekscore: A decision on whether to use Logitech MX Master 3S or the Logitech MX Master 4 might appear like an opposition between two star players. They are both highly productive mice, yet the MX Master 4 is giving a few new features that may cause you to think about a new upgrade, or the MX Master 3S is simply half the cost of that mouse. We shall also take them apart, their design, features, battery life, connectivity and their price so that you can pick the right one.

Comfort and Design

The Logitech MX Master 3S has a comfortable, curvy design, which fits like a glove regardless of the size of your hands. The rubbery grip and slight ridges ensure that your hand is not tired and the thumb rest with side buttons ensure ease in navigation. It is sleek and with color choices such as black, pale gray and graphite, it appears to be sharp as compared to smooth technology devices such as an iMac. The Logitech MX Master 4 takes a step backwards in this formula, placing less emphasis on the rubber, in favor of a more accurate feel of fingertip grip. It is a bit larger, but it slides more with improved PTFE feet, and it is not so inclined to wear out with time. My vote in this will go to the more luxurious feel of the MX Master 4.

Features and Customization

The Logitech MX Master 3S is a powerhouse having buttery-smooth MagSpeed scroll along with side buttons and a Logi Options+ software. You can transfer files across computers, automate repetitive processes, or even create AI prompts on ChatGPT. The Logitech MX Master 4, however, brings it to a higher level with a more conveniently placed gesture button, and a new trendy Actions Ring, which opens a customizable menu of shortcuts. Besides, its haptic feedback (it has four intensity levels) will be a game-changer with sensitive tasks such as video editing or design work in applications such as Adobe Premiere or Figma. The unequivocal is the MX Master 4 that is all about the latest features.

Battery and Sensors

Both the mice are powered with the Darkfield sensors provided by Logitech with good tracking at 8,000dpi, including on glass. The Logitech MX master 3S has a battery capacity of 500mAh with a charge life of 70 days and a one minute charge gives three hours. Logitech MX Master 4 increases the battery capacity to 650mAh, which matches the 70-day specification although the haptic feedback consumes a little more power. The larger battery also provides the MX Master 4 with a minimal advantage.

Everyone must have Internet access, and the Internet needs to be available everywhere. Connectivity and System Support Everybody should be connected to the Internet, and the Internet must be everywhere.

The Logitech MX Master 3S is Bluetooth 5.0 or has a Logi Bolt which is USB-A and is compatible with Windows 10/11, macOS 10.15, Linux, ChromeOS, iPadOS 14 and later and Android 8.0 and later. The Logitech MX Master 4 is now capable of updating to Bluetooth 5.1 and USB-C Logi Bolt, at the expense of older operating systems like windows 10, starting with windows 11, and macOS 13 and beyond. The MX Master 3S comes to your rescue when you are still operating one of the older ones.

Price Point

The Logitech MX Master 3S base is priced at 99 (Bluetooth) or 119 (Logi Bolt) and I have observed it retailing as low as 79 during sales. The Logitech MX Master 4 does not exceed $119 in any model. The cheaper option in terms of budget is the MX Master 3S that I would choose, particularly on sale.

The Bottom Line

The Logitech MX Master 3S is an excellent option when an individual desires an excellent performance without necessarily spending beyond his or her pocket, particularly with the old systems. However, the Logitech MX Master 4 with its smooth appearance, haptic feedback, and advanced features is the best productivity tool to the majority of customers. The upgrade is worth it, should you be willing to spend big.
