Default J3 drains battery overnight???

A few days ago my J3 stayed dead when I woke up and switched it on. After charging for a while it said 25% battery.

It's strange because I charged my J3 fully the night before and didn't use it afterwards. And even if J3 was accidentally turned on playing music all night, the battery couldn't drain that fast. At least it never did.

It happened twice. At first I thought it was something to do with the new UCI I installed sometimes before. But then my friend's D2 got this very same problem. Battery dropped dead without use, no change in software. Didn't think this battery-theft thing was random anymore.

Suspects:
Recently we BOTH started to use the USB 3.0 ports in our new laptops to charge J3 and D2. After switching to USB 2.0 port and adapters, everything seems normal until now. A search on this problem showed so result. I do not dare to use USB 3.0 again though I don't know whether it causes the problem. It's tempting though, saying a USB 2.0 device could be as fast as it can on USB 3.0 port.

Thanks for reading and any suggestion would be appreciated.
