Low power mode doesn’t automatically engage anymore and no battery 20% and 10% notifications anymore either since iOS 18

I’ve tried everything there is to try possible to get low battery mode to automatically switch on like it used to before ios18 came out. Doesn’t even give you notifications that battery is low when gets to 20% and 10% and I’ve definitely lost track a few times and phone died multiple times. I know how tragic right? lol. But really only thing I’ve done different was change new setting to display battery percentage all times since it came available. So I’m gonna give it a try and see if that changes anything. But please give us automatic enable low power mode or at least give us an alert notification banner saying it’s at 20% so on. Maybe even 30% if not going to give us automatic low power mode so we have somewhat of an extra time to get to charger.
