Samsung Galaxy Watch9 Review: Fitness Strengths Meet Battery Limitations
The Galaxy Watch9 is a smartwatch designed to help people exercise and monitor their health.
It is thin, light, comfortable, and easy to use.
It can automatically recognize activities such as walking and jogging.
Its heart-rate tracking worked fairly well, but its step count was sometimes too high.
The watch also measures sleep, blood oxygen, skin temperature, and breathing rate.
Most sleep information was useful, although it often said the wearer was awake for too long.
The main problem is that the battery lasts only about a day and charging is slow.
Some health features work only when the watch is paired with a Samsung phone.
The Galaxy Watch9 is a lightweight, comfortable Android smartwatch with a bright display and 50-meter water resistance.
Its activity tracking and heart-rate readings were generally accurate, although step counts appeared inflated.
New software features include overnight vitals, Fitness Index, Daily Cardio Load, and an improved AI Running Coach.
Sleep tracking was mostly accurate, but the watch consistently overstated time spent awake.
Battery life reached about 27 hours with the always-on display enabled, while a full charge took over an hour.
