XPS 15 Battery Drain while Shut Down (solutions on forums Haven't worked)

I have disabled connected standby on the dell registry, disabled fast start-up, and disabled sleep. However, completely randomly my battery drains to around 5% within minutes. The process normally starts like this: I turn on my computer where I see the Dell circle, then I log in, my battery is around 90% and it says that I have 1 hour and some minutes, and then after a minute, the battery time either changes into 5 -8 hours or it just gets to 5%. I downloaded a battery report for an example of this problem and it's attached. The report says that 67% of the battery was drained within a minute. I would appreciate any help!
