I have Endomondo installed on my phone and with the recent update a few weeks ago they added wear support. Thing is, it really drains the battery. So I want to just use Endomondo on my phone, but not my watch. For some reason, whenever I start the app on my phone, I still get excessive battery drain. The app on the phone and the app on the watch still must be communicating with one another. Can you just uninstall an app off the watch?
