  • Galaxy Watch 6 has a maximum of 2,000 nits brightness to read in harsh sunlight & perfect for outdoors, while the Galaxy Watch 4 has a maximum of 1,000 nits brightness.
  • The Galaxy Watch 6 runs Wear OS 4 with One UI 5 Watch for a smoother user interface with more customization options, better accessibility, and optimized app performance compared to the Galaxy Watch 4’s One UI 4 Watch.
  • It has a new temperature sensor that enables menstrual cycle tracking and ambient temperature detection, which is not available on the Galaxy Watch 4.
  • The Galaxy Watch 6 has enhanced HR zones and advanced sleep coaching for detailed health tracking, while the Galaxy Watch 4 has standard HR zones and basic sleep tracking.
  • It features Sapphire Crystal Glass for better scratch resistance and durability, while the Galaxy Watch 4 uses Gorilla Glass DX+, which is less durable.
  • The Galaxy Watch 6 has a 300mAh battery for delivering longer battery life of up to 40 hours, whereas the Galaxy Watch 4 has a smaller 247mAh battery.
  • The Samsung Galaxy Watch 6 supports faster charging, reaching 45% battery in just 30 minutes, while the Galaxy Watch 4 charges slower, taking longer to reach the same level.
  • Upgraded Bluetooth 5.3 in the Galaxy Watch 6 ensures a more stable connection, improved range, and potentially lower latency than Bluetooth 5.0 in the Galaxy Watch 4.

Maybe the Galaxy Watch 4 price can make you comfortable because it’s a little bit cheaper than the Galaxy Watch 6. But you have to compromise all the above-mentioned features. Now the Decision is Yours. I hope it was helpful to choose the right one.
