What you need to know

  • A new leak suggests the upcoming Galaxy Watch 4 will come equipped with a BIA sensor.
  • A Bio-Electrical Impedance Analysis (BIA) sensor is used to assess a person's body composition.
  • Samsung is expected to take the wraps off the Galaxy Watch 4 and Galaxy Watch Active 4 at its MWC event next week.

Earlier this week, we got our first look at the design of Samsung's upcoming Galaxy Watch Active 4. Now, a new leak has revealed one of the key features of the Galaxy Watch 3 successor. According to reliable tipster Max Weinbach, the Galaxy Watch 4 will feature a BIA (Bio-Electrical Impedance Analysis) sensor to enable users to easily measure their body fat percentage in relation to the lean body mass.

Since body composition is directly related to health, the Galaxy Watch 4's BIA sensor will allow you to better track your current state of health. While BIA sensors are common in smart scales, it looks like Samsung will be the first company to add one to a smartwatch.

The follow-up to Samsung's best Android smartwatch was initially rumored to feature blood glucose measurement as well, but recent reports suggest Samsung has dropped the feature for some reason. It is expected to come with a circular AMOLED display featuring thinner bezels than its predecessor, an SpO2 sensor for blood oxygen monitoring, and an all-new Exynos chipset built on a 5nm process.

As announced at Google I/O 2021 last month, both the Galaxy Watch 4 and Galaxy Watch 4 Active will be running the unified "new" Wear OS platform co-developed by Samsung and Google.

Samsung's Galaxy Watch 3 offers a bright AMOLED display, fantastic battery life, and a nifty rotating bezel that makes navigating through the UI a lot easier. The smartwatch also comes with a wide range of health-tracking features — including blood pressure monitoring.

  • I don't need my watch to tell me I'm fat. Is this actually useful to anyone?
  • Doubt it. It's just another marketing angle that probably won't even be activated on the watch for the first 18 months like they did with ECG and Blood Pressure
  • Maybe that's why it's something useless... Something with actual value would require validation and Certification.
  • lol, adding a new feature, but reverting to WearOS. Yeah, they aren't going to oneUp Apple Watch by leaving Tizen
  • Well, at least you gave it a chance...
  • Tizen's been holding it back for long enough. Ditching it for Wear is long overdue
  • Umm, no. Tizen is why I left WearOS. It didn't work for me the way I wanted, so I have stayed with Tizen but now I may not have a choice once current watch flames out. I may just go back to a regular watch and call it a day.
  • And Wear is why I'll be leaving Tizen when it's added to the Galaxy 4. My Watch 3 and Watch Active are OK but having no Google Pay, Google Assistant or Maps is just horrible. Can't wait to get those back
  • A new sensor telling one how fat they are ? There's also an ancient arcane device available that has been used for such a purpose for thousands of years with high specificity and sensitivity. It was even used indirectly for communication. It's a mirror
  • Damn, that's savage 😂😂😂
