Is there any official response from Garmin on the obviously rampant problem of poor battery life of the Edge 130?
There are various threads on this. Garmin doesn't care. I wonder if the new Edge 130 "Plus" is any better for battery life? I went out on one of my biggest rides of the year this past weekend, a Ride to Defeat ALS fundraiser. Just before hour 10, I noticed my screen was blank. It was done, and I still had nearly 2 hours to go. Now my Strava post is so sad, with a big straight line from where it died to the parking lot where I plugged it back in at the end of a long day.
You could say Backlight = Backlight, whether the device is big or small.
However bigger devices have a bigger battery, so the impact of the backlight is smaller on bigger devices.
My Etrex has 2800mAh batteries, and has no problem with backlight.
The same Etrex lasted 28h(!) outside in the freezing cold (GPS+Glonass and ANT enabled - bcklight off)
