Samsung Galaxy Watch9 review

The Galaxy Watch9 is the strongest pick for Android owners, and it ranks second overall. Samsung's US store prices the 40mm Bluetooth model at $379.99, the 44mm at $409.99 and LTE at $429.99. The product page lists a sapphire crystal display up to 3,000 nits, a Snapdragon Wear Elite platform, Wear OS with the Google Play Store, and Google Gemini for voice tasks. Health tools in Samsung Health include Bedtime Guidance, a sleep apnea feature, Energy Score and an Antioxidant Index. Battery capacity rose to 390 mAh on the 40mm and 445 mAh on the 44mm, and Samsung's answer on its store page puts use at about 40 hours without the always-on display and up to 30 hours with it. The catch is phone choice: several sleep features need Android 13 or above, and some Vitals functions require a Samsung Galaxy phone. We compared documented features and published prices only.
