First use?

[draxa]

Hello,
so I bought myself a brand new iphone 6s and I am wondering how will I use It for the first time?
Should I use it immediately "out of the box" and drain the battery till phone turns off or should I first plug it to socket and charge It till battery reaches 100 percent?
On internet there are lots of information about that but I am not certain which is the correct way.

Welcome to iPhone Forums!

You don’t have to drain the battery until it turns off, it’s also not necessary to charge it immediately. Both won’t increase battery life.

Hi,
So there is no strictly procedure. Just to turn the phone on and start using It.

You will need to put a Sim Card in to activate it. (A nano-sim to be more accurate).

Ok thanks..tell me is It neccessary to keep the phone always above 10 percent of battery? Some sources on the internet advice that battery never should be under that percentage due to longer battery life

That’s not necessary. Don’t let it drain on a regular basis. If it happens, charge it immediately.
