Dont let the phone get too hot particularly when charging so dont use it much when charging dont leave it near heat sources dont charge it in a pocket or a closed space etc. You can then see the charge percentage next to your iPhone battery icon.
Battery health is important since iPhone battery is by far one of the main components that cause the device to start running slow when its capacity gets to 80 cap or less.
