iPhone 15 Pro Max optimized charging not working
I've been using the iPhone 15 Pro Max for almost a month now. My work is schedule is 7am-7pm. Every night I charge my phone at 10-10:30PM but I don't see notification for the optimized battery charging. Which is better should I change to limit battery charging to 80% or keep on optimized battery charging? another question is it safe to keep the phone 100% everyday?
