Why is my iPhone 13 Pro Max taking so long to charge?

I have my iPhone 13 Pro Max plugged to a PC with Windows 10. The PC is about 8 years old, I guess. I don't know what kind of USB it uses. It is a USB plug. I have Optimized Battery Charging turned off. I did have it on for a while after I purchased the iPhone about a month or two ago. It takes hours to charge it ... Maybe as long as 4 hours.

Why does it take so long? I turned the Optimized Battery Charging off so it would charge faster. I watch it so that it doesn't keep charging after it reaches 100%.

That was when I was using iOS 15.4, or whatever was before 15.5. I just updated to iOS 15.5. Should that solve my problem?

depending on how you charge it, via charger plugged into a wall socket, or via USB connection to a computer, charging time may vary. Make some tests about that.
There's no possibility of overcharging an iPhone's battery. When it reaches 100%, the device automatically stop charging. I use to charge my iPhones since 2008 overnight (everynight), regardless of the charging level of their battery.

There is nothing wrong with using optimized charging. Depending on the power source, it may take awhile to charge a phone. I plug my phone in at night and have a fully charged phone in the morning. You can’t overcharge a phone so don’t worry when it gets to 100%. My phone can be charging anywhere from 10 to 12 hours a night.
