How long do I charge iphone6 battery for the first time ?

Until it's at 100%, or at a level you're comfortable using it with.

Let me give you a decent answer to your question.

I have had lot's of different Iphone's and android phones but the answer I give you is something

which applies to any electrical equipment using a batterie.

You should fully charge your Iphone and use it till it switches off for around 6 times minimum you will see

an increased battery life after each charging cycle.

I never had battery issues with my Iphone's I use my batterie till the iphone switches of then charge it fully.

If I can not do that in the week coos I need my phone I will do this ones on the weekend.

If my phone has 15% pr 20 % left and I know I need it fully charged for the next day I will switch on the light option and use

up the battery till the iphone switches of then charge it.

Why do we do that ? Batteries use cells if they are not used after a time become useless and you end up with a phone charging only up

to 89%.

I have been using this method for years and it keeps battery's lasting a long time and being efficient.

Nonsense, the worst thing that you can do to a Lithium Ion battery is to fully discharge it.

Your advice is not only wrong, it is dangerous!
