Reviewing the Xiaomi Watch S5, a budget 46mm smartwatch costing £150 in the UK boasting some of the best battery life of any smartwatch in 2026. I've been testing the Xiaomi Watch S5 for a few weeks now, so here's my full verdict. Check out my other smartwatch reviews and a round-up of my favourites here on Tech Spurt!

While the customisable design has been ditched from the S4, the Xiaomi Watch S5 boasts some sleek design that defies the budget price. Performance is pleasingly smooth, although that battery life is certainly the highlight here. You've got plenty of fitness tracking shenanigans stuffed on here, plus the usual sleep and stress monitoring of course.

The Xiaomi Watch S5 runs HyperOS, so it's more limited for notifications, payments and apps vs the WearOS smartwatches. However, if you don't mind the more basic features and crave ridiculously long battery returns, you may well be swayed by this budget watch.
