eSIM vs SIM battery usage

[Richard_Indy]

I decided to setup and use the eSIM option for my AT&T S25U when I first set it up.

I am curious if using an eSIM uses less battery than a SIM card would. I also wonder If the difference is measurable.

One way that physical connections (ex. SIM card in SIM card slot) in electronics can lead to increased power consumption, is resistance.

I haven't seen a difference, pretty much all my phones are Esim for a good 2 years now.

I didn't even this was a thing?

I figured it's just based on your network. How much of a difference are difference, if any that one needs to worry about it.
