I've been using the ios 17 Dev Beta since day on my 14 PM and never experienced any issues while using FB, Threads or IG. I also never heard of anyone complaining about heat until the 15 models hit the street.
I usually turn off background for all social media. They're nosey, battery hogs.
Gonna have to disagree. With BAR turned off, Facebook, IG and Google consume much less battery. It makes a huge difference in battery life. It must change something about how they behave.Turning off Background App Refresh does not stop apps from running in the background. They're going to run in the background regardless of whether BAR is on or not. Most of the time apps work better with BAR on. It allows them to update and refresh in the background. Being nosy has nothing to do with apps running in the background.
