My Dell XPS 9500 battery went from 70% to 26% while suspended for 24 hours. /sys/power/mem_sleep setting says it is deep. To compare, an ubuntu lenovo laptop I own will use 5-10% battery while suspended for 24 hours. Is this a tumbleweed issue, or a dell issue?
Welcome back !
So, how old is the laptop and battery?
(I see reviews going back about three years.
We have a Dell laptop (not with me at moment) that easily gets two days in Sleep mode … and a slightly older Lenovo laptop , which has a battery that lasts about one hour, so yea, need a replacement).
I’ve had the Dell XPS for two years and the battery capacity is 75%
