A collection of the best smartwatches currently on the market. Our pick is based on design and features but, above all, the battery's durability.
Smartwatches are becoming a usual accessory on our wrists, just as smartphones are in our hands.
They can wake us up in the morning, tell us how much and how we slept, record our exercise routine, and accompany us in the shower. Going to work, we can read and answer messages without taking the phone out of our backpacks and even play with an app while we wait for the bus.
However, what good is such a great device if it runs out of battery in a few hours?
Advancements in smartwatches' battery life are not as fast as the introduction of new features they offer. The greater the functionality and the better the specifications, the shorter the battery life. The most renowned case is the Apple Watch, which, being considered the best smartwatch, only lasts 18 hours - and it seems unlikely that they will improve this any time soon. The same happens to Samsung's Galaxy Watch 3, which requires charging every night.
So is there a long-lasting battery alternative without sacrificing functionality?
The answer is yes - and not just one: there are models for every taste: military-styled, for fitness or running lovers, Apply-looking, and even elegant.
The following list includes five of the best models with the most extended battery life on the market.
