S3 sleep / suspend to ram on Ubuntu 18.04
Um... unless I'm completely missing some recent change... ARM processors such as the RK3399 don't have ACPI sleep states such as S1 and S3!

3% / h does sound like something isn't being powered down. ARM processors are pretty good at going into a real low power sleep... i.e. my 11" Pinebook (1st gen, not the Pro) with the A64 cpu can be left in sleep mode for weeks, not the day and a half, that it seems your PBP would be in.

Out of curiosity (since I don't have a PBP yet, so this may not even work), does

echo mem > /sys/power/state

put it into sleep mode? Maybe it's not going to sleep properly?
