i fully charged my one month old XPS 13 9360 two days ago and then powered it off and unplugged the AC adapter. this morning when i powered it on it showed only 86% battery remaining. so it drained 14% while it has been powered off in two days. is this normal?
i was on the phone call with Dell support just now and frankly it did not help me at all, he basically had me run battery test which it passed and check my bio version which is up to date, he then said this normal after put me on hold for 10 mins while checking his documented similar cases, saying while the system is off the battery is still working on supporting the hard drive (his words).
i do have a question, i always leave my usb mouse adapter in the laptop while it's powered off, do you guys think it'd improve the drainage if i remove it whenever i power down the system?
