When it comes to battery life, Fitbit wins hands down, said Gebbie. "The Apple Watch offers an 18-hour battery life, which means you need to charge it every day, whereas many Fitbit trackers and watches can last for days or even weeks at a time without charging.
"This simplicity and reliability is attractive to a lot of users, and our research at Connected Devices has always found that battery life is hugely important to customers.
"However, the Apple Watch offers a more polished user experience than even top-end Fitbit smartwatches, with a more advanced operating system and a wider suite of services.
"This means that the Watch is something of a Swiss Army Knife and is intended to reduce wearers’ reliance on their smartphones by offering a powerful experience on the wrist."
