SK17i user here and I noticed while using usb tethering, my battery drop from 100% to 80%...

Happened to anyone else too????
Is this normal?

Thanks

if you re using front usb port then switch to on board usb2.0 ports. i faced the same problem and it was solved by changing the port. hope that it will help.
