If you define the best smartwatch as having the longest battery life, then Mobvoi’s TicWatch series has set a high bar. The dual-display wearOS watches manage a month or more between top-ups in their lowest-power states – and now there’s a new one aimed specifically at athletes and fitness fans. The Ticwatch Pro 5 Enduro is skinnier, tougher, and has better health tracking.

Essentially a slimmed-down TicWatch Pro 5 with a few new tricks, the Enduro is less than 12mm thick on your wrist, while still finding space for not one 1.43in circular screen, but two: there’s a low-power transparent LCD on top of a bright, colourful OLED, so the watch can tell the time and other basics even if it’s running low on juice.
