Fitbit Charge 4 update brings Smart wake, Dynamic GPS

Fitbit Charge 4 gets a couple of significant features the company has introduced into its smartwatches. The first one is the Smart Wake option, which uses the sleep tracker to help you set the alarm to wake you up when you feel the most rested. With sleep disrupted profoundly by the COVID-19 pandemic, this feature is particularly useful. If you can spare the time (you should really), this feature might be an excellent way to wake you up in the morning.
Another is Dynamic GPS, which lets you connect the tracker with the GPS on your phone when it's in range. This function helps preserve the Charge 4's battery life as well as improve location accuracy. The fitness tracker also now lets you decide how long the display stays on when it has been awakened. The Fitbit Charge 4's official retail price is $199.95, but it's currently on sale over at Fitbit's site at $169.95.
