The 44mm and 40mm sizes of the Samsung Galaxy Watch 4 differ in their designs. Further, the design of both Samsung Galaxy watches is identical, with the only difference being the weight and dimensions of the devices.

Talking about the appearance, Samsung’s Galaxy Watch 4 sports a more appealing and stylish look. It comes with a polished aluminum metal frame. No doubt, it’s trendy and long-lasting thanks to the high-quality material.

The frame is made of Corning Gorilla Glass DX+ that is scratch-resistant and water-resistant up to 50 meters. In addition, the straps are composed of silicone, and you may also adjust the strap to suit your needs.

However, the 40mm is a more compact and comfortable smartwatch with a dimension of 40.4 x 39.3 x 9.8mm and weighs only 26g. The 44mm, on the other hand, measures 44.4 x 43.3 x 9.8mm and weighs 30g. Nonetheless, you can clearly see that both are incredibly lightweight, compact, and easy to wear.

As a bonus, both sizes come in a variety of eye-catching colors. The 44mm is available in black, silver, and green, while the 40mm is available in black, silver, and pink-gold.

Overall, the 44mm size of the Samsung Galaxy Watch 4 is suitable for men and women. However, 40mm is the best size for ladies with small wrists.

In addition, you’ll get a Super AMOLED display that allows you to see clearly even in direct sunlight. Aside from that, the resolution is outstanding because the 40mm watch has a 396 x 396 resolution, while the 44mm variant has a higher resolution of 450 x 450.

All in all, the Samsung Galaxy Watch 4 (44mm) is best suited for those with wide wrists, whereas the 40mm model is more suited to those with thin wrists.

Before choosing any smartwatch, it is essential to look at its battery life.

Compared to the 40mm, the 44mm has a larger battery capacity, allowing you to go longer on a single charge. It has a 361mAh battery, which is higher than the 247mAh of the 40mm. As a result, the 44mm can last up to two days on a single charge, and the 40mm can last up to a day and a half or more.

Fortunately, using power-saving modes can help you get more time out of your battery. There are several methods you may use to improve the battery life of your device, such as:

  • Decrease the brightness level
  • Limit the number of apps that send you notifications by turning them off.
  • Turn off WiFi and GPS

Samsung Galaxy Watch 4 44mm vs. 40mm: Price

  • The LTE model of 40mm costs $299.99 while 44mm costs $329.99

Hence, it is evident from the above comparison that 44mm has a larger display and a longer battery life than 40mm. 40mm, on the other hand, is smaller, lighter, and less expensive than 44mm. Apart from these variations, both models offer the same fitness and activity tracking capabilities to help you reach your fitness goals.

 In addition to these new health-tracking features, there are numerous more health-tracking features such as sleep tracking, heart rate tracking, ECG, blood pressure, and blood oxygen measurement.

SpO2 sensors, which monitor your body’s oxygen levels, are also included. Other activity tracking capabilities, such as sleep tracking, calorie counting, automatic workout tracking, stress, hydration monitoring, and much more, are also available.

Samsung Galaxy Watch 4 also has a fall detection feature that’s worth noting. When a watch senses a hard fall on the ground, it automatically contacts emergency services or sends a notification to the wearer’s emergency contacts.

The Galaxy Watch 4 can follow your routes and deliver more precise data with built-in GPS.

As an LTE or cellular connectivity, you can make and receive phone calls and text messages right from your smartwatch without using your smartphone. You’ll also be able to receive alerts from Twitter, Facebook, and Instagram directly on your wrist.

It also features a microphone and loudspeaker that allows you to listen to the music or make and receive calls from the watch. Additionally, contactless payment is a huge benefit. You don’t need to carry a wallet or credit card if you use NFC to pay all of your bills.

Also, it is water-resistant to IP68, so you may use it while washing your hands, swimming, or having a bath without fear of damaging it.
