I don't know if anyone else has this problem with DC on android devices, but it drains the battery (on 3 different devices) at a phenomenal rate. What is that?! My battery can last for days without dragons open/running. I open the app, do my versus or watch videos on Freebie Island and 50% battery- GONE. I always end the app after I close it because I know it's a battery sucker, so it's not like it's just running in the background wasting juice. Anything the developers can do about this? Or just get used to charging the phone after 20 minutes while Dragoning?

That seems a high amount, you might want to try:

1. clearing your cache
2. running your maintenance cleaner to clear the device's cache
3. Turning off the device for a few minutes
4. uninstall and reinstalling the game **ONLY do this one if your game is linked to facebook. I assume it is since you said you tried it on three different devices.

If none of these helps in the battery consumption I would send a ticket to support. FYI I play 5 games and run most of the same type of actions and during each Play setting my battery only drops 25-30%.
