What’s New?
The GTS 2 comes with a loudspeaker and microphone that enables it to make and receive calls directly from the watch with a connected phone Bluetooth, this isn’t possible with the GTS. The GTS 2 also welcomes SpO2 blood oxygen that tracks you blood oxygen levels to determine how well your blood utilizes oxygen. PAI is also available on GTS 2, this feature gives you a personalized health score by calculating your heart rate and other data. Menstrual cycle tracking app has also been added, this comes handy for women to track their period cycle.
However, even though the GTS 2 has a higher battery capacity, it lags behind in terms of battery life, it has a shorter battery life than GTS. While the GTS can go up to 2 weeks, it’s about a week with GTS 2.
Basically, the GTS 2 is a better smartwatch than its predecessor. You can learn more about what’s new on GTS 2 in the video below.
