iPhone 12 Pro and 13 mini issues after iOS 26 update

I have a 12 Pro and my kid has a 13 Mini. It has messed everything up. The camera has a lag, all my apps keep freezing, the lock screen freezes or lags when trying to open the phone, my home screen lags or freezes, my battery all of sudden started draining twice as fast, no matter how I try to mess with the setting my ringer and media volume end up adjusting together causing my ringer/alerts to be silent, the haptics are messed up and don't work half the time, my wallet has had my cards (tried two different ones) to decline occasionally, my maps app has shut down while using it and there are a few more issues I have been running into.
