Battery Life

How can I extend the battery charge life?
I am at 100% brightness. 20 mile ride with sensors and Bluetooth and segments cost me 25% battery charge. Would never make a century.

Thanks

    Default brightness (60) is bright enough for me, and I am on track, with segments or routes, hr, speed, cadance, and BT, to hit 15 hours most days.

    That being said, one day I left it on, and it drained itself to zero. I was able to plug a cheap $10 phone charging stick thing in, and it not only powered up, after 2.5 hours of riding (about 30-35 miles) it was at 100% charge. I had the stick in my bike bag, wrapped the cord around my toptube a number of times, and had the device in the extended mount.

    Another similar option is to use the charger at all the rest stops, depending on how long you stop, this may be enough to work for you.
  • I did a 4.5 hr ride at the weekend, backlight on constantly at about 70%, Ant+ sensors for cadence & speed, GPS and the other one on, battery life ended up at 70%.
    If you lose 25% charge over 20 miles then you have to ride a lot quicker :D

    Similar experience to Al above.

    Couple weeks ago I rode a ~4 hour GranFondo (Edge 520 was powered on for about 5 though as I rode into the start line and left it on), with Bluetooth connection to my phone, GPS/GLONASS, 3 sensors paired (HRM, SPD/CAD and a power meter). I was doing the Garmin live tracking thing as well so my wife could watch me and plan when to be at the finish area (neat feature!). When I was done the Edge was at ~70%. I didn't use backlight (15sec timeout) however as I found the visibility to be decent, even during the changing lighting conditions of a winding mountain road course on a sunny morning.

    As a side note, even with the live tracking my phone (Galaxy S5) only went down to about 75% over the 4 hours.

    I've seen similar results on rides since then (obviously not all live-tracked though...). It appears like I'm getting 5-7% battery use per hour of operation, which is similar to what I got on my old 500.

    Too funny.....

    Yea....lol...I left out that I average about 17/hr.

    I guess it's the brightness (needed for 50 y/o eyes) that's draining the battery. :rolleyes:
  • Coming from an Edge 800, then an Edge 1000, I find my 520 is by far the best battery life. I only have the ANT sensors I am using at the time on, BT on, and keep the screen turned down and I find the battery to be excellent. This is in my opinion the best Garmin I have used for my needs.

    Have you tried a lower brightness setting. I have older eyes than you and find 60% is good enough even in tough shadow conditions. If I am sitting inside staring at the screen 60% looks way too dim. But when outside riding I can see it fine. 60% will drain the battery a lot less than 100.

    I run mine at 70% and it looks fine outside. 100% brightness is not necessary. Also, are you riding with the back light turned on all the time? If so, that is going to really eat into your battery. Lastly, you can reduce the back light timeout which will also help to maximize your battery life.

    How long is this '20 mile' ride? 25% in 20mi is kinda nuts from a full charge unless the back light on the whole time and/or it took you 5hrs.
  • I ride with backlight on all the time at 60 - 70%, gives a really clear display, (my eyes are 50+ yrs...) far better than peering at my old 500 LCD screen. It does not drain batteries much (down from 100 to 70% in a 4.5 hr ride) and thats with bluetooth on, GPS +GLONAS, ant+ heart rate and cadence/speed all running.

    I just did a 4hr 10 min ride. Everything on full, 100% brightness, Bluetooth, GLONASS & GPS, buy end of ride battery was about 15%. So I lost 85% in 4hrs. Thats terrible compared to my 500? So I will try 60% brightness and I might turn bluetooth off as don't need that till upload and see what I get?
  • From my expereience so far,

    60% brightness / GPS + GLONASS / backlight always on - About 10% battery an hour
    60% brightness / GPS + GLONASS / backlight 30 sec off - About 6-7% battery an hour
