I don't even charge to 100%, only to like 90-95% because I don't charge overnight (i set my charging limit to 95 so it won't even let me turn on optimized charging). so i'm a little confused: what you're saying is that because I am using Apple's official charging materials, it IS ok if I let it heat up every day by using my phone while it charges, or not?
You are micromanaging your battery, which isn't going to help you. The Battery on Hold warning is the new normal when Fast Charging your iPhone. It was introduced last year and when using a fast charger, charging will rapidly rise to 80%, then pause until the battery cools, then resume to the charge level you've set. To answer your question, the Charging on Hold notification is NOT going to damage your battery.
On the charge level, it is more gimmick than anything. Avoiding charging your phone to 100% isn't going to save your battery much, if at all. I read an article from a respected tech person, who put two iPhones side by side for a full year. Both phones were used exactly the same. Both phones were charged at the exact same time. One phone had the charge limit set to 80%. The other phone had Optimized Battery Charging turned on. At the end of a full year, both phones had the exact SAME Battery Health. Micromanaging your battery takes time and won't do much of anything to preserve the health of your battery.
The absolute best practice for battery charging is to plug your phone in to charge when you go to bed, leaving it plugged in to charge ALL night, EVERY night with Optimized Battery Charging turned on. You'll wake a fully charged phone, good for a days use.
Or you can drive yourself crazy and try to micromanage your phone charging, which in the end isn't going to extend the life of the battery at all. Think about it logically. Limiting the charge limit won't change how often you need to charge your battery. If anything, it may cause you to charge more often. But a cycle charge is one from 0% to 100%. Whether you charge from 50% to 100% twice or 80% to 100% 5 times, is still one full cycle. As I said, it's more gimmick than not.
