Fitbit Charge 4 gets ‘smart wake’ alarm and dynamic GPS with latest software update – Report Door

The latest software update to the Fitbit Charge 4 gives two big upgrades including dynamic GPS, and a smart wake option. First reported by 9to5Google, the new features are now rolling out to all users.
Dynamic GPS allows you to connect with the GPS in your phone if its in range, which may help with location accuracy and preserve the Fitbits battery life. If your phone isnt close enough, the tracker will revert to its internal GPS, which can drain the battery more quickly.
The Smart Wake feature is a pretty cool addition; it will work along with the wearables sleep tracker, and set alarms to wake you at the time youre likely to feel most rested. Another new option allows users to decide how long the screen display stays on once the Fitbit has been awakened.
In addition to the new features, the Fitbit Charge 4 also has Spotify control, a seven-day battery life, and other premium features that used to be reserved for its smartwatches. Released earlier this year, the Charge 4 sells for $149.95.
