## Questions people ask

**How long does the battery last?**

Up to 11 days in smartwatch mode or up to 19 hours in GPS mode - the only listing here that gives both numbers.

**Does it have built-in GPS?**

Yes, and it is one of only five watches here that track position on the wrist.

**Why is it only fifth?**

Because of the price, not the quality: it has the best rating here and the deepest evidence per pound on the running side.

**Does it need a phone?**

It records runs on its own, and pairs with a phone for notifications and sync.

**Why does it say Portuguese?**

Because the specification table was written for another market; the language and shape fields are both wrong for a UK listing.

**How many ratings does it have?**

4795 at the time of collection, averaging 4.6 stars, with 81 per cent five-star and 4 per cent one-star.
