Which is better, unplug my iphone once fully charged, or leave it plugged in?

Hi all,

I have a question regarding an Iphone, and it's battery consumption. For years, I have been charging my phone overnight (this phone and others), without an issue from a battery perspective. From what people are telling me, this is not the correct way to charge your phone for maximum battery relaibility.

I have heard from different people that below as all the best options, but I do not know which is correct.

1 - it is best to remove the phone from the charger as soon as it's complete

2 - It is best to leave your device on the charger for a short time after it's fully charged so the battery can keep it's charge.

3 - Do not remove the device from the charger mid-way through it's charging because it will reduce it's ability to keep a charge over the long run.

4 - Charge the phone as needed because of the Lithium Ion technology (my option)

I see on the apple website that #4 is the best option. I just want to see what the actual users are saying on this subject.

Thx,

John
