Do "Running services" deplete battery? What about "Cached background processes"?

[androidmatcha]

In Settings>Developer_Options>Running_Services, I see several things that I don't need.

I believe that unnecessary services that run are unnecessarily depleting my battery, leading to a shorter battery lifespan.

I use my fingerprints to unlock, so I'm not sure if I need these services that I see are on the list of "running services":
★ Face
★ Intelligent Scan
★ Iris

Question 2. Do "cached background processes" sap my battery?

I see the following "cached background processes" https://imgur.com/a/vb9EsuD

Here are some that I don't need:

★ Bluetooth
★ NFC
★ Samsung DeX System UI (My Samsung phone is not connected to an external monitor/computer)
★ Google VR Services (I don't need/use VR)
