Edge 1040 Battery Life

Took my first ride with an Edge 1040 Solar.  I started off fully charged, rode 1 hour 10 mins during which time the solar intensity was always around 60%.  By the end the battery was down to 79%.  The Edge reported that I have recouped 1min 14 sec due to solar charging.

It was a free ride with a heart rate monitor, speed sensor and cadence sensor.

I was surprised to see that I lost a fifth of the battery after just over an hour.

I this typical of what you guys are seeing?

    You don’t mention the backlight settings ( % and “stays on” / seconds to off) and the phone connection status, these two things are by far the biggest power eaters . I have a non-solar , don’t use any backlight during day, don’t have any connections while riding and I get 80-100 hours depending on navigation usage.

    Thank you for this response.  I had my screen on all the time but I will have to have a better look at the backlight % which can probabaly be reduced.

    Can you elaborate a bit about "phone connection status"?

    Do you have your phone "paired " and "connected" to the 1040 via Bluetooth (BT) and if so what is it doing (during the ride), live track, group track, receiving messages etc, all these take a fair amount of processing power and thus battery. If you only have the connection so you can upload the ride at the end of the ride then have it paired but disabled until the ride ends, connection is then only for a minute rather than hours, even if it isn't actually doing anything during the ride maintaining the BT connection is power hungry.

    In sunlight, even indirect daylight the screen is very clear without backlight though some sunglasses can be an issue due to their polarisation orientation. I prefer to explicitly set the backlight % and timeout levels rather than leaving it up to what the garmin thinks is "best" so I  don't use auto setting or "battery saver" functions as I find there to be excessive.

    Thank you L.Rouge - That was very helpful
