Yeah, something's definitely up. Why is the tablet draining? Have you tried another device?
The two should not be connected at all. But you need your tablet to see when the battery is getting low - especially if it's far enough away so you can't see the lights on the craft.
Can you go into the battery section on the app and do a screenshot? Maybe the cells aren't balanced, or maybe one is shot? What is the battery temperature like?
Don't fly it far away until you see a solution would be my advice!
