Fitbit's new smartwatch can do 3 important things that the Apple Watch can't

Fitbit says its new smartwatch should last for more than five days on a single charge, meaning you shouldn't have to worry about remembering your charger if you go away for the weekend. That's far longer than the Apple Watch, which in my experience usually lasts for 1.5 to two days before I have to charge it.

It's unclear how well Fitbit's claims live up to reality, but in my previous experience, Fitbit's first-generation Versa was able to last for around the same amount of time.

But if you choose to take advantage of the optional new always-on screen, your watch will probably only last for roughly two days.

Fitbit devices have long offered basic sleep tracking, and the company is expanding that yet again with the Versa 2. The company is rolling out a new feature called Sleep Score, which rates the quality of your sleep based on factors like your heart rate, how long you've slept, and how much time you've spent in light, deep, and REM sleep.

If you want to track your sleep with the Apple Watch, you'll need to download a third-party app, some of which cost money.
