Bolt 3: Need advice fixing drastic battery discharge

Long time Elemnt user, just wanted a device with longer battery life than my current Bolt 2.

Today was a first longer ride with a recently bought Wahoo Elemnt Bolt 3. After just over 9 hours device just died. I’ve analyzed FIT file, extracted battery data and below is a chart.

Most of the time I had an active route navigation and phone connected (current iOS) (until 22% level when I stopped route in device, unloaded Wahoo app and disabled Bluetooth on a phone). 3 sensors were connected all the time: BT power, ANT di2, BT HR.

Cloudy all the day, so no super high screen brightness (set to Auto), +10-15 degrees C, so not cold. Mostly using data fields screen.

Need advice how to fix battery draining.

I have no fix for you but that is a helluva ride!
