Hi, I reciente got the iPhone 16 pro max and I overcharged it once. Will overcharging it one start damaging my battery? I left it charging and forgot, it’s the only time I’ve charged it and it overcharged. Will that one situation start to degrade by battery’s health?

Hey there,
iPhone automatically stops charging when the battery is fully charged, so it's safe to keep your iPhone connected to a charger overnight. Charging resumes automatically if your battery level drops below 95 percent.
When possible, unplug your iPhone after it has fully charged. By default, your iPhone uses Optimized Battery Charging. To improve your battery's lifespan, Optimized Battery Charging reduces the time that your iPhone spends fully charged. It fully charges your iPhone just in time for you to use it.
A battery warms up as it charges, which can reduce its lifespan. To reduce the effect of heat and prevent overheating, iPhone gradually reduces the charging current as the battery approaches full charge.

All The Best!
As posted above, you can not overcharge the battery. Leaving it connected to the charge circuit after the battery reaches 100%, is not an issue. It has no effect on the long term battery health.
Thank you, but will overcharging it once damage the battery’s health? I’m just super stressed that I started to damage the battery’s health because I overcharged it once. I’m always super attentive, but this is the only time I overcharged and know I’m stressed if managed the battery’s health already
Will overcharging affect iPhone 16 Pro Max's battery life?
