How to maximize Versa 4 battery life when competing in a 100KM walk

[AndreaLgn]

I’m competing in a 100km walk and want my Versa 4 to last the 24 hr projected time. 
what is the best way to maximise battery life and turn off all notifications?

Hi @AndreaLgn - turning on watch sleep mode from Quick Settings, pull down on the watch face, will dim it, stop notifications and requires button or double tap to wake it.

Logging off the Fitbit App and turning off Bluetooth can help automatic sync quiesce.

However if you are using watch GPS that will drastically shorten the battery life to the 5 hrs quoted (sometimes it can be more if you can enable phone GPS instead but you will need the Fitbit App and Bluetooth).

Wake the display as little as possible.

Restart and fully charge before starting should give you the most autonomy.
