What reviewers say

Reviewers agree the larger, wide-angle display and thinner, lighter case make it more comfortable and easier to read, helped by much faster charging and sleep apnoea detection. The common complaints are unchanged 18-hour battery life, no performance gain over the Series 9 and, in the US, the disabled blood oxygen feature; The Verge called it another year of minor updates.
