The Charge 4 is Fitbit’s first fitness tracker. It’s durable and waterproof, but it’s also packed with features that are generally exclusive to larger connected watches like the Fitbit Versa or the Apple Watch. Fitbit is now pushing the Charge 4 even further in premium territory with Smart Wake, Dynamic GPS and customizable display timing functions.
These new features, which are part of firmware update 1.96.29, should help preserve your battery life, improve your mornings and eliminate some annoying quirks of Charge 4. Some of these features were previously exclusive to Fitbit’s Versa smartwatch, so they may look familiar to you.
Dynamic GPS is a new battery saving tool that allows the Charge 4 to take a break from communicating with GPS satellites. If you work with a mobile phone, the Charge 4 automatically extracts the GPS information from the phone. Dynamic GPS eliminates the need to manually switch between device and phone GPS, which very few people have taken the time to do.
Smart Wake is an intelligent alarm system that helps you wake up feeling rested. Basically, the Fitbit waits for you to enter a moment of light sleep before waking up gently. If the Charge 4 does not detect a moment of light sleep within 30 minutes of setting off your alarm, your alarm will sound at the set time. You must activate Smart Wake manually when configuring an alarm.
The adjustable display timeout function is exactly what it looks like. If you are not satisfied with the 3 second delay of Charge 4, you can dive into your settings and keep the screen awake for 5 or 8 seconds instead.
You should receive an update notification in your Fitbit app today. Otherwise, come back tomorrow. These things may take a while to deploy.
