Our verdict	Remains a popular choice despite criticism of its battery limitations. Praised for improvements in sleep tracking and new health insights, maintaining a strong position due to brand recognition and feature set.	Still the benchmark for sleep and recovery tracking. Battery lasts 7-8 days. Long-term user reports show only minor capacity loss after a year.	Its presence on a top-5 list demonstrates some level of community approval, although less enthusiastic than for the Gen 3 model.	Latest model adds a larger display, improved battery (~10 days), and better integration with Android health services. Samsung’s service network is global. Firmware updates are frequent and stable.	Ultra-light (2 mm) design, up to ten days of battery life, and a robust sensor suite. Long-term Reddit threads report no major hardware failures after 18 months.	Slightly thicker than the Air but offers a larger battery (~10 days) and more robust build. Long-term user reports show no major failures after two years.	Older but still reliable for sleep and heart-rate monitoring. Battery life is around six days. Long-term reviews show consistent performance after 18 months.	The comparison against the Oura Ring 5 demonstrates competitive performance and suggests it offers a viable alternative with similar functionality.	The original model still performs well for basic sleep and activity tracking. Battery lasts about six days. No widespread failure reports after a year.
