win10 battery drained so fast unexpectedly, Dell Inspiron 15-5559

any help or explanation to a symptom like this ?

pushed power button then over night, the battery is completely drained, also no boot, repeatable.

shutdown the machine but no goes into sleep mode, the battery is safe without overnight drained issue, but still some leakage about 10% overnight. The battery report generation mechanism has wrong ? or really the PC hardware fault ? or Win10 bug ?!

Turn off Fast Startup. Under Windows 10, your computer does not totally shut down with Fast Startup on. It can actually be running processes when you think it is "shut down". If you leave it off AC power for any length of time, it can drain your battery. With Fast Startup off, your computer will boot slightly slower, but it should not make a big difference.

thanks. it is being a workaround at this moment but so far not the solution for an ordinary user, unless Dell or Microsoft is willing to look at such problem and to tackle with a clean & neat solution. can we say that win10 *** on this topic ?
