For the Fitbit Charge 4, a software update is released that adds some very useful new features to the wearable, including improvements in GPS handling, sleep management and the use of the monochrome display.
According to the help document on the Fitbit website, version 1.96.29 of the device software enables dynamic GPS: the tracker uses your phone’s GPS to determine its location when your phone is close enough, and this should extend battery life (otherwise) charging 4 is reset to its own GPS sensor.
Another upgrade for the device is Smart Wake ̵
The Fitbit Charge 4 can already track how deeply you sleep. So the theory is that he can wake you up from your sleep at a convenient point. This is a feature we’ve seen on other wearables, including Fitbit.
Apply the update
Another notable new feature that comes with the update is the ability to customize how long the device’s display stays on before going into a dimmed standby mode. So if you still need a few seconds to read the screen, you can add it here.
Note that this is an update for the software that runs on the Fitbit Charge 4 itself – sometimes referred to as device firmware – and not for the mobile apps for Android and iOS (although you need the phone app to update apply).
The update is apparently being released. If you haven’t already, you should have the update on your wrist shortly. If you are not automatically prompted to install the software, follow Fitbit’s instructions here.
The Charge 4 could be the end of Fitbit devices as we know them – Google’s purchase of the fitness tracking company last year is likely to affect future wearables, and we could even see the long rumored Pixel Watch.
