850 Battery Life - OUCH!

The 850 has a great new display like 1050... but battery life is only 12 hours... Less than 1/2 that of a 840.

GARMIN WHAT ARE YOU THINKING?  Please explain yourself.

  • 8-9% per hour is the normal consumption with or without active navigation 

  • I don’t know how DCRainmaker het almost 19h with 30% brightness? The estimate hours given by the edge 850 is far from reality.

    it says 45h at 40% brightness and backloght stys on…but after 3h ot drops to 28h

  • battery life estimates when using auto-brightness will never be accurate - it has no way of knowing what light conditions it will be in and hence what the screen brightness will be. i guess with all previous generation devices the screen was not such a massive proportion of the drain so it was possible to give a reasonable estimate but with the x50 the screen seems to eat most of the battery so if your ride is all in bright sun then the drain is going to be really high just to keep it readable and garmin seem to have completely failed to consider that.

    with a fixed brightness it should be very accurate though - seems like they've completely screwed that one up, will probably be a software update in 6 months to fix it once they get through all the other likely bugs
