Despite being around for almost two years since it was released in August 2018, the Galaxy Watch is still one of the best smartwatches you can buy today. For one, it runs on the same Tizen 4 as Active 2 and was also updated with most of the UX features on Active 2. You can get the Galaxy Watch in two sizes; 42mm and 46mm. Each of these two is available in LTE or Bluetooth only. In this post, I compare the Samsung Galaxy Watch Bluetooth vs LTE to find out the differences.

Samsung Galaxy Watch (46mm) LTE vs Bluetooth: Video Comparison

Samsung Galaxy Watch (46mm) LTE vs Bluetooth: The Difference

  • The design on the LTE and Bluetooth is the same, it’s same colorful AMOLED display, physical rotating bezel, and stainless steel material for the case. The 22/24mm straps are the same on both sizes.
  • The fitness tracking features are also the same, you can expect any of these two to track your steps, floors climbed, calories, heart rate, sleep, outdoor activities like routes and locations.
  • However, the difference between the Bluetooth and LTE model is the presence of cellular connectivity on the LTE model which the Bluetooth model lacks. As a result, the LTE model is a standalone smartwatch that allows you to make and receive calls directly from the watch.
  • You can also make and receive calls from the Bluetooth model, but it must be connected to your phone which can cause some level of inconvenience especially while running or in the middle of another activity.
  • The LTE model also has a higher 1.5GB RAM compared to 0.76GB of the Bluetooth model. I can really say how this affects performance on the LTE model, but from my experience, the Bluetooth model has one of the best and flawless performance I’ve seen on different smartwatches. Mind you, LTE isn’t available in every country of the world.
  • On average, the Bluetooth only Galaxy watch 46mm can go up to 4 days from a single charge, this is higher than that of the 42mm of 2 days or more. You can expect the LTE models to go a little less than this considering the cellular features.

Which is Better?

I’m not a fan of standalone smartwatches because I think it complicates what a watch should be, but there are people who like standalone functionality in smartwatches probably because of the convenience and freedom it gives the phone. If you’re like me, the Bluetooth model is a great choice, while the LTE is a more comprehensive smartwatch and a great choice for anyone that fancies standalone features, but will cost you some extra bucks.
