My iPhone has an "Optimized Battery Charging" option under Battery in Settings. If it is on, it will only charge it overnight until 80% and won't charge it the final 20% until just before you normally wake up in the morning. I have used this successfully for many years without causing battery issues.Avoid charging it overnight (it won't "overcharge", but it will fully charge up to 100%).
It won't cause "battery issues" per say. iPhones have smart batteries and charging to 100% will not "damage" the battery, it will simply cause it to wear faster. All that does it prevent a tiny bit of wear and still give you a 100% charged phone in the morning. Battery health means battery wear. Poor battery health will not cause issues, except for reduced battery life. Liion batteries are not like cars that can run equally well at 5 miles to empty (ignoring additional wear on fuel pump from sucking in contaminants at the bottom of the tank) or 400 miles of range– they have preferences. Imagine a car that gets the best mileage at half a tank and you're on the right track.
iPhone 15 and newer have a feature that allows you to permanently limit charge to 80%, which I've been begging for for years. It is unavailable on the 14 or older which I find ridiculous, but at least it will be on my next phone. I have to manually unplug my phone every time it hits 70-80% so this would be great.
I've been doing this for years and I have phones with batteries that show health 10-15% higher than other people who just plug it in. I've been able to make a battery last a year or so longer since I started keeping it out of heat as best I can and not charging to 100%. It's just a good habit to have, but it's not the end of the world if you prefer more charge. Even 10% / 95% goes a long way compared to 100% and 0%.
Another thing to keep in mind, your iPhone gives you the full % of battery. Samsung phones limit the charge to 10% (give or take) and 90%. The Samsung displays 100% and stops charging, but the battery is at 90% of mAh capacity. I think you can use the hidden 10% for emergency calls only or something in the Samsung. This is to protect the battery as explained. I do not believe this can be turned off.
Your iPhone gives you the full charge. 0% is 0% and 100% is 100%. This is bad for battery wear over time and you will get noticeably fewer charge cycles (although still probably a thousand or two) before the battery is struggles to hold a charge.
Lastly, there is evidence that Apple is intentionally limiting the charge cycles before battery health declines, for planned obsolescence in the battery. Up to you whether you believe this but I wouldn't be surprised and it tracks the battery health decline I've noticed in my phone vs my older phones. It isn't in their best interest to give you a battery that wears well and a lot of people will buy a new phone when their battery is crap. Worst case, they'd love to sell more iPhone batteries.
