FAQs

Q: Do I need cellular connectivity in my smartwatch? A: If you frequently exercise without your phone or want the ability to make calls independently, cellular connectivity is worth the extra cost. However, be aware that it requires a separate data plan with your carrier.

Q: How accurate are the health metrics on smartwatches? A: The accuracy has improved significantly, with many watches now FDA-cleared for certain measurements. However, consumer devices should not replace medical equipment for those with serious health conditions.

Q: Can I shower with my smartwatch? A: Most modern smartwatches are water-resistant to at least 50 meters (5ATM), making them suitable for showering and swimming. However, hot showers may degrade water resistance over time, and soap can damage seals.

Q: How long do smartwatches typically last? A: The hardware typically lasts 2-4 years, but software support varies by manufacturer. Apple and Samsung usually provide updates for 3-4 years, while budget brands may offer less support.

Q: Are there privacy concerns with smartwatches? A: Yes, smartwatches collect significant health and location data. Review the privacy policy of the manufacturer and adjust data sharing settings according to your comfort level.

Q: Do I need a smartphone to use a smartwatch? A: Most smartwatches still require initial setup with a smartphone, but many now offer standalone functionality with cellular connectivity. Some specialized fitness watches can function independently after setup.

Q: What’s the difference between AMOLED and Micro-LED displays? A: AMOLED offers deep blacks and vibrant colors but can suffer from burn-in over time. Micro-LED provides similar benefits with better brightness, efficiency, and longevity, but typically at a higher cost.

Q: Can I answer calls on my smartwatch? A: Most modern smartwatches allow you to answer calls, though the experience varies. Models with built-in speakers and microphones let you take calls directly on the watch, while others require Bluetooth headphones.
