I have the S21 ULTRA 256, exynos, and I installed BBS and want to know what drain my battery.
In Kernel Wakelock, I have 19f00000.decon_0 process with high usage.
Someone else has this process ?
Nothing on Google about it.

Just understand. Other process are common and comprehensive, this one not.
What's the point to answer to a post if you can't help. Just comment for nothing.

I suspect it is connected to the function of the phones display ,and from the following links decon stands for display and enhancement controller. Check out the following links
https://forum.xda-developers.com/t/13800000-decon_fb-wakelock.2936445/
and this one ( search for decon on the page)
https://www.anandtech.com/show/9330/exynos-7420-deep-dive/3
and this one ( bit out of date)

Thanks. Really helpful.
So if it's a display process, I suppose that's normal.
But I'm not sur that this process must to be in the top of the battery drain process.

I don't think that represents the battery percentage, it it the percentage of the total accumulated time of the wakelock acquirement in relation to the battery time since being unplugged . You can check it yourself to confirm it from your attachment above, 1hr16min43secs divided by 5hrs14min29secs *100 =24.3%.
So in that case , although it will be using power , I don't think it represents 24% of the battery
