The common causes of battery drain are:

1. out of date GPS software
2. a corrupt gpx file or manually added folder to the GPS Internal Storage
3. sub folders created by the owner in the Internal Storage

Please can you confirm that you have:

1. the latest Platform and GPS device software in your GPS

The latest software updates are:

a. Platform version: Platform 43
b. GPS software: Beta Version 3.13.107

You can download it over SatSync or WiFi.

The Beta version is what we recommend people download as the software offers more fixes and some extra features. If there is a problem, you can always 'roll it back' to an earlier version.

2. deleted all routes, tracks, POI's and any additional folder that you have manually added to the Internal Storage, from the Internal Storage

3. you could also try hard resetting the Active 20 by holding the power button for 20 seconds to power it off and then turning it on by holding the power button for 3 seconds before charging it. This can also resolve any power/charging issues.

4. reset the Active 20 to the Factory Settings by:
Main menu screen>Settings>Default>'Yes'
