I’ve been having a really frustrating issue with my iPhone 12 lately and I’m wondering if anyone else has experienced something similar.
Whenever I use the phone while it’s charging—specifically when scrolling through Instagram for about 20 minutes—the device starts lagging and stuttering uncontrollably. It’s not just a minor hiccup; it’s a constant, "never-ending" lag that makes the phone almost unusable until I stop using it or unplug it.
I suspect it might be thermal throttling, but I’m also wondering if my battery health is to blame. Since I’m a student and don’t have the budget for a new phone right now, I really want to make this one last.
My battery health is 80
