Question E-sim + Physical sim = battery impact?

[amirage]

Hello comrades,

I plan to switch to an e-sim and use a physical sim whenever I travel abroad. I know the battery life goes for a toss when dual sims are enabled. Does this apply to e-sims? Can our comrades here please share their experience running dual sims on their devices? Appreciate your comments.

E-sim or not, the power consumption is still there because the modem is still being utilized.

Gotcha..what sort of a battery drain are we looking at? The other option is to carry a second phone for the international number! Is the trade-off better this way i.e. the inconvenience of carrying a second device < the inconvenience of the battery drain

Well...difficult to answer. It depends on the network coverage, the bands being used, and if you're utilizing 4G or 5G. In my case, having 2 sims increased my IDLE battery usage by about 50-60% approx. So, usually, one sim was around 1% idle, and dual resulted in around 1.5-6% while the DATA was active.

Hey, thanks for this. You nearly caught me there with the 50-60% figure but in real terms, I think the trade-off is small such that carrying a second phone would be an inconvenience. Is your dual-sim setup on 5G or 4G? I'm assuming the drain would be less brutal on 4G than on 5G.

When I only used one pSIM in my device. It easily got 2 days worth of battery life out of it before I wanted to charge it. I get pretty much about the same using one pSIM and one eSIM.

Lol, when I was writing the "50-60%" I had that possibility in my mind.

IMO, it's not that BAD with dual sim. But if the network coverage gets really bad on both sims, those numbers might drastically change.

when i used only 1 sim my battery life was impressive i got easily 8h of sot with around 15% battery left. When i inserted my second sim the first day wasnt so great i got 6 or 7h of sot with 4g enabled on both sims then i changed the second sim to be just on 3g because i use it mainly for calls and the battery life improved a little bit (note that was a month or so ago).
But now i didnt change anything and the battery life improved like i just have 1 sim card installed.

Battery life will hugely depend on the signal quality you're getting from both SIMs as if one or both are struggling to hold the signal, your drain will increase dramatically.

You can not have esim and physical sim at the same time, the phone does not allow it. It has to be 2 physical or just esim.

The U.S. variant does not have two physical SIM slots - only one. And I at least have no issues with one physical SIM active and one eSIM active at all times.

There would be no other way for the U.S. variant to be "dual SIM," since it cannot have two eSIMs active at once.

That's a really stupid configuration.

Are you talking about some specific model, because I have one physical SIM and one E-SIM both active at the same time...

Really...now that's really stupid..let me check this out

Can confirm that physical ans esim work simultaneously.

My fault, I have seen that you can not have the sim and, esim in the same tray, so I have put the sim in tray 2 and it works, thanks.

Hey guys, do you know if having a disabled physical sim impact battery life?

My primary sim is an esim, and the secondary sim is physical sim that i keep disabled.

It shouldn't.

Well, single sim vs dual sim does have an impact on the battery. Disabling one sim should improve your idle usage by some % (depends on many factors, but the improvement is still there considering that the modem needs less power).

I actually run dual (physical+esim) and the battery life is still amazing mind you my first sim is on 3G/2G because I only use it for calls and sms and second one 5G/4G for data only
