I've had these earphones for a few weeks now and they're great, the one issue I'm having is that the battery drains overnight.

I often use them to watch netflix on my tablet in bed, they start with 100% and usually have 80-90% left when I'm done. 

When finished, I turn off the bluetooth on my tablet and switch it off. I take the earphones out and leave them on the side, they are set to switch off when taken out of the ear.

When I wake up, they are always down to 1 or 2%, what am I doing wrong?

I don't put them back in the charging box as quite frankly, I shouldn't have to as they're set to switch off when taken out of the ear.

Any suggestions would be greatly appreciated.

Thanks in advance
