Battery consumption

Good evening, 
I wanted to know how much battery your 1040 consumes at each session. 
Mine with the power sensor, cardio, speed sensor and radar consumes at least 4% every hour. 
It seems excessive to me. I hear of people with less consumption.

I average 2%-3%, depending on how much the solar recharges. I typically stay on standard datafields screen, no map. Power meter, tail light, speed sensor.

Depends hardly on your backlight settings. I‘m at around 3%/hour with auto backlight, active navigation and map view.

mine 30% with auto backlight

This is what Garmin support expects

Today 9% after 1:40 ride. I don’t understand why

One thing to watch with battery consumption is the combined effect of the radar and backlight.

You may not notice it in daylight riding, but each time the radar activates, it also triggers the backlight. Depending on your backlight settings, if you are riding in urban areas (ie. lots of traffic and radar activations), that can be a LOT of backlight.

Turning down the backlight intensity (you probably only need 10% for nighttime riding), and shortening the backlight duration can make a BIG difference to battery consumption.

I actually got rid of my old 520 Plus out of frustration because it wasn't lasting a 200km ride, before I discovered this combination effect of radar and backlight.

Same with laptops I guess; the backlight has a major affect on battery life. I would recommend to leave it on auto mode. I can also imagine that the map screen is more cpu intensive than a screen with only some numbers, because the screen it redrawn more frequent, and vector graphics require a lot of math. So I think it's possible that leaving it on the map screen affects battery life as well. It may be interesting to do some testing on that.

Garmin have done it for you and my "testing" confirms the higher battery life with the more "saving" oriented settings, I get 70++ (non-solor) (although the "Auto / Stays On" for the 90hr column seems like a mistake in the table, more likely something lower like the 70hr column)

Good morning, I did other tests.
Always with Auto and Always on on screen.
Even today 9% of battery consumption in 1:30h.
I go out early in the morning without the sun with a lot of shadow and light alternating.
In fact, a lot of consumption occurs in the first hour before the sun rises.
My total battery life estimate is 28 hours maximum.
