One common problem for the mate 20 series..

[1982-1994]

I own both mate 20 and mate 20X.
Realised that though both achieve very high SOT,
Kirin 980 sucks in battery standby. Left my phone doing nothing for like 2hrs, gone 2% battery.

Thought the big battery of the X might be different, but I was wrong.

Anyone encounter the same thing?

I think the question is what have you installed in your phone? Do note that some apps drain battery, for instance, Facebook. This is not something new because some apps are constantly running in the background even though you think it is closed.

Not that. I have scanned through 'app launch' and set all not to run in the background. Perhaps Google play services is the culprit.
