What reviewers say

Wareable and PhoneArena find the larger screen easier to read and use, and praise fast charging for making overnight wear more practical. Both report responsive performance and effective activity tracking. Battery endurance changes little from Series 6; PhoneArena finds launch sleep tracking limited, although Wareable's updated review notes later sleep-stage support.
