G'day!

My old Apple I phone 5s is getting to be past it's use by date - voices in conversations are somewhat distorted.

Had it for years - been dropped, [lots of times]  even for 1/2 a second into water!

Question -

What do I need to do to back up the whole contents of this old phone onto a win 10 laptop, so that I can then install all my contacts etc onto a new phone.

Probably going to Samsung S8   - hope that does not confuse the issue further.

TIA  !!
