I’m much the same. My partner has a 12, regularly runs it to the point it switches off. Her battery health is 87%, only about 18 months old. However, my 12 Pro had terrible battery life-I sold that after 2 years and its battery health was at 81%. I’m a light/casual user.
I have a 14PM, it was replaced under AC+ between Christmas Day/New Year and my battery is still at 100%. I could almost get two days out of it, but it doesn’t always quite make it to bedtime the second day. I use a slow wireless charger every night, and my percentage is usually between 40-45% when I do this. Even on iOS 17 Beta it’s hitting the same levels.
To those worrying about battery performance, our household experiences with a 12/12 Pro battery have not been great. My experience with my 14PMax has been brilliant. I’m not one to get seriously hooked on my gadgets, but do love this phone. It is weighty, but not that much-I don’t really notice it now.
I wouldn’t splash out for one now, but if any are in the market post-15 release, it’s a hell of a phone.
