Polar H9
Score: 83/100
Samsung Galaxy Watch 7
Score: 81/100Rankings
The Polar H9 is a chest-mounted ECG heart-rate sensor offering exceptional accuracy and a 400-hour battery life. Its main trade-off is the lack of onboard storage and reliance on a replace-once coin cell battery. Ideal for athletes who need precise data across multiple sports and appreciate dual-protocol connectivity.
The Samsung Galaxy Watch 7 40 mm delivers premium build quality, advanced health tools like Energy Score and sleep-apnea detection, and a fast 3 nm processor. Its relatively heavy design and unspecified battery endurance may deter users seeking lightweight, long-lasting wearables. It's aimed at Samsung ecosystem users desiring a high-end smartwatch experience.
