This video provides a review of the Samsung Galaxy Watch 7, focusing on ten key aspects. The reviewer shares their experiences and initial findings after a week of use, covering battery life, accuracy of health tracking features (heart rate, sleep, and GPS), and other notable features like the new processor and band options.
Colors: The Galaxy Watch 7 comes in 44mm (green or silver) and 40mm (green or cream) sizes. The green color is darker than in product images, appearing more like dark gray. The cream color is similar to silver.
Bands: The default sport band has a ribbed design. New fabric and athleisure bands are also available. The fabric band is softer and easier to use than last year's version, while the athleisure band is lightweight and comfortable for workouts.
Processor: The new processor is significantly faster than the Galaxy Watch 6, resulting in quicker app loading and responsiveness.
Charging: The included USB-C cable (5V, 2A) charges the watch fully in approximately 1 hour and 19 minutes using a 20W adapter. Wireless charging from a Samsung phone did not work.
Battery Life: Average battery life was 47 hours over three cycles (45-50 hours range), with an average of 44 hours of on-wrist time (41-48 hours range). Disabling blood oxygen and skin temperature tracking during sleep slightly improves battery life. Always-on display usage impacts battery life.
AGES Index: This new metric indicates metabolic health and biological aging but its current usefulness is unclear.
Energy Score: This new feature provides a daily measurement of physical and mental energy based on sleep, heart rate, and activity levels. It suggests whether to increase, decrease, or maintain activity levels.
Sleep Tracking Accuracy: Sleep start times were generally within 10 minutes, and end times within 20 minutes of the reviewer's estimates. Naps were also tracked.
GPS Accuracy: The dual-frequency GPS system showed excellent accuracy in testing, consistently matching other devices (Apple Watch Series 9) in distance measurements during walks and bike rides.
Heart Rate Accuracy: Heart rate measurements during various workouts (walks, bike rides, spin classes) were mostly accurate when compared to a Polar H10 chest strap and an Apple Watch Series 9, with only minor discrepancies.
The ten things you should know about the Samsung Galaxy Watch 7, according to the video, are:
Colors: Available in 44mm (green or silver) and 40mm (green or cream) sizes. The green is darker than shown in product images. The cream is similar to silver.
Bands: Includes a sport band; new fabric and athleisure bands are also available.
Processor: A new processor is three times faster than the Galaxy Watch 6.
Charging: Uses a USB-C cable (5V, 2A) and charges fully in about 1 hour and 19 minutes with a 20W adapter. Wireless charging from a Samsung phone was unsuccessful.
Battery Life: Average battery life is approximately 47 hours (range: 45-50 hours), with an average of 44 hours on-wrist time (range: 41-48 hours).
AGES Index: A new metric indicating metabolic health and biological aging; its practical usefulness is unclear at this point.
Energy Score: A daily measurement of physical and mental energy based on several factors.
Sleep Tracking Accuracy: Sleep start times were typically within 10 minutes, and end times within 20 minutes of the reviewer's observations. Naps were tracked.
GPS Accuracy: The dual-frequency GPS system showed high accuracy, comparable to the Apple Watch Series 9.
Heart Rate Accuracy: Heart rate measurements during workouts were largely accurate compared to a Polar H10 chest strap and an Apple Watch Series 9.
