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.

eSIM and physical SIM have similar battery usage for single connections. Battery drain increases mainly with dual SIM use or poor signal strength, not the SIM type itself.

I'm headed back to SIM. A few days ago, my S25U died in a fall from the roof of my house to the brick patio. Not pretty. Without going into the problem with getting Samsung to hold up on their end with the Samsung Care+ coverage I had, the other big problem is no phone until the replacement arrives. I have ordered a SIM card for US mobile from Amazon, will be here tomorrow and I can place that old fashioned piece of paper into my old, but still working Pixel 4XL until the refurbished S25 arrives.
If I had a paper SIM in the destroyed S25U, I would not have been without phone service any longer than removing SIM from S25U and inserting into the 4XL.
When the S25U comes in, I will remain with the old fashioned paper SIM card.

As for the replacement, it was a pain in the rump runaround from Samsung, to the point this S25U might be my last Samsung (no decision made yet). Could guarantee a return to Pixel if it was not for that fugly candy bar camera housing on the rear. Hear the Pixel 10 will be the same...need to do some research....

Adding my probably unhelpful experience.
I run a physical and esim at the same time all day every day. This method allows both to always be active as opposed to one being standby.

I make it through probably 2 days with basic use. 1 full day with screen time. I only charge to 80%.

Individually, each module (the physical slot and the processing needed for the eSim) should come out to be about equal. I can say however in weak signal situations one is stronger than the other but can't test atm since I live near a tower that pushes over 1 Gigabit speeds with full bars.
