What are best practice to charging iPhone battery?

Make sure that Optimized Battery Charging is turned on.

Connect the phone to the power adapter and leave it connected all night.....every night.

Never let the phone get down to zero charge.

See the advice from forum expert Lawrence Finch here:

and maybe iPhone Battery and Performance - Apple Support

and Batteries - Maximizing Performance - Apple

Do not allow it to drain to Zero. The rest is up to you.
