iPhone Xr Battery + Screen Time
So I've been using my iPhone Xr for a week now, and I've got to say that the battery has been awesome. For some reason, I've been getting only around 4-5 hours of screen time, and others days i get close to around 6. It's pretty inconsistent. I charge my phone in the morning with a 29w usb type c fast charger and it gets to 100. People have been claiming on communities such as reddit and reviews that they have around 7 hours of screen time with a full charge. I'im wondering what I should do or if I should be worried at all. I have background app refresh OFF for all of my apps and I'm using the latest ios as of right now. I want to be able to pull more with this bad boy, but idk if it's the indexing or actual hardware that's been sucky.
Thoughts?
Keep in mind that fb and sc say that they've been running in background, but I have them turned off in Background App Refresh.
