iPhone 15 battery draining without use
I’m finding my new phone, which arrived on Monday, has a shocking battery life. Overnight, it’s lost 40% of its charge despite not being used. I don’t have any notifications enabled and I’m not sure what’s going on.
Is this normal for the iPhone 15, or do I seem to have a dodgy model?
I’ve upgraded from an iPhone 11 with a dying battery health, but even that one is no where near as bad as this!
iPhone 15, iOS 17
