Does using dual SIM on iPhone XS use more battery life?
It doesn’t really matter if it’s dual sim. If you’re in poor network zone then your phone will burn through battery faster. With dual sim, it just increases the chances because the phone wants to stay connected to 2 networks always.
Negligible. The biggest battery killers is screen brightness and apps running in the background. Eliminate them and you're good to go.
Don’t think so.
If one uses auto brightness then the screen doesn’t use as much battery as one would like to think due to the nature of OLED panels.
Also iOS handles background activities amazingly well. Apps don’t run indefinitely in the background. If you’re not actively using the app then iOS kills the processes after about 10 mins.
Poor network connectivity, on the other hand, kills battery faster because the device constantly tries to hold on to the signals.
So, I guess with Apple's magical software solutions the phone will last forever without a recharge? So tell me, if it's not screen usage and background apps, what drains the battery?
I explained everything in my post. By the tone you used in your post I sense you’re going to just come back with random comments and ignore what I’ve mentioned. This early in the morning I’m not willing to entertain that. Enjoy your device as you please to use it just don’t spread misinformation.
LCD or OLED the screen and background processes are going to use the most power. Very seldom is the screen mostly black where an OLEDs efficiency would actually be useful.
You won`t have much impact with the second SIM. Both SIM`s are using only one Antenna. Only one is Using 4G and the second remains on Voice only.
This isn't true at all. I bought a dual SIM phone from Amazon—and it's a basic one—yet the battery only lasts for a few days even without usage (I tested it on standby with 2 SIM cards active and battery saver mode turned on).
With 1 SIM card, the battery life is extended to up to 21 days on standby, four days short of what's promised in the box. It's a Nokia 8110 4G.
Ha ha ha.
Not gonna say anything to that.
I use that as an emergency device so I can always be reached.
I have been using dual SIM on my iPhone XS Max in Europe for the last 2+ months and there is definitely a noticeable reduction in battery life. I would estimate ~70% of standard battery life when using dual SIM.
I think it depends on which SIMs you have too. My US SIM is always roaming while in Europe, which I'm sure contributes to battery drain. But I' also guessing most people use dual specifically to serve multiple locales, so my experience should be pretty representative.
Technically speaking, yes. However, in practice, there are other things that will affect the battery life more than the dual SIM themselves in standby. Dual SIM technology is not new.
