Garmin 520 Battery Drain

The last 2 rides I have charged the battery overnight 100%. The next day, I get started and the battery will be totally dead in 4 miles, say 15 minutes or less. I keep the unit and the chest strap stored apart from each other. I usually don't check the battery to see what % it's at when I start off with what I am assuming is a fully charged battery. Any ideas?

Battery failure is almost certainly the reason.

The unit is less than a year old. Will Garmin replace the battery? It is a 520 Plus.

Garmin won't replace parts. However, if this issue is covered under warranty, then it would likely be replaced with a new or refurbished unit.

Are you sure you're turning it off once it is fully charged? I had the same thing happen to me once or twice where I charged it, put it on my bike that night and when I woke up in the am for my ride it died in about 5 minutes. You may have left it on without "Sleep Mode" enabled (or turned it off completely).
