That’s interesting, wardsamuel! I wonder if the battery drain is more about the apps or the dual SIM itself. Have any of you tried switching to a single SIM to compare?
I tested it out and found that using a single SIM definitely improved battery life but wasn’t as convenient for juggling work and personal calls. I guess it’s about what you prioritize.

I’ve found that while the performance is mostly solid, certain network conditions can affect call quality on one of the SIMs. Sometimes I have to switch manually.
Exactly! I’ve noticed my second SIM only works well in certain areas. It’s a bit hit or miss.
From what I gather, it really depends on your area’s coverage. In low coverage, both SIMs struggle, so you might not be getting the best out of the S21 Ultra.
Has anyone experienced any heating issues while using dual SIM? My phone gets warm during heavy multitasking and dual SIM usage.
Yep, I’ve noticed it too, creynolds! It’s not alarming, but my S21 Ultra does get quite toasty when multitasking and using both SIMs. It might be the processing power needed for all those tasks.
I’ve had my S21 Ultra for a while and think using dual SIM is fantastic, but the battery life dips with heavy app use. Still, the feature outweighs the drawbacks for me.
Agreed! I’ve gotten used to charging more frequently, but I love the flexibility dual SIM offers.

I sometimes wonder if this is the future of smartphones. However, will future models be even better at managing battery life?

To be honest, it’s still a bit of a balancing act. Better battery tech is on the way, but who knows if it will match our needs with dual SIM?
I chuckle thinking about how I used to change SIM cards manually. Now, I can just switch between them with my S21 Ultra. What a time to be alive!
Haha, totally! I remember the constant hassle of swapping. Dual SIM is a game changer, but I could do without the heating issue when pushing it!
I’ve been using the S21 Ultra with dual SIM for a few months. It works seamlessly with both my local carrier and an international one. The network switching is pretty quick, which is a big plus!
That’s great to hear! Are you facing any issues with data usage when switching networks?
I’ve heard that the S21 Ultra supports 5G on both SIMs. Is that correct? I want to know if this works well with different carrier bands!
Yes, it does! I tested it with T-Mobile and AT&T, and both connections were fast and stable. No major complaints here!

The dual SIM feature is amazing for traveling. I use one SIM for work and another for personal calls. Switching between them is super easy in the settings!
What about notifications? Do both numbers show alerts separately when someone texts or calls?
Yes, you’ll get distinct notifications for each line! Makes it easy to manage your calls and messages without confusion.
