Will Iphone 5 be slow on IOS 9?

So my friend is selling me a Iphone 5. Not a 5c or 5s.Basically Iphone 5 is the same as 5c.Anyways he selling it to me for a good affordable price and its in very good condition. But IIm scared if I end up buying the iPhone and ios 9 comes out, my device is going to be very slow! Because before I had a Ipod 4g and when I updated it to ios 6, my ipod became very very slow and crashed on every app! I tried restarting it and it was still the same.Basically my ipod became very useless and I had to end up getting an android phone. But please I need help! I don't want to make this mistake and waste my money!

If I write a letter of complaint to apple, will I get a free iPhone?

I have this faulty iPhone 5c which is unable to be fixed and I have only had it about a year! So I want Apple to send me a replacement phone as it's unacceptable and I'm not spending £100's just for it to happen again in a shorter space of time or something, so if I write a letter of complaint will they replace my phone because they sort of have to.

Is it worth paying for an iPhone 6 clone?

I was thinking about investing in an iphone 6 clone out of interest as I need a new phone. I have a low budget for what I would spend on a phone online and came across these. I was wondering if anyone has any experience with the higher end of quality with these replicas could tell me if they work. I was looking at the so called "best clone of the iphone 6 in the world" and it sparked my interest… So do they actually work?!
Thanks for reading (and hopefully answering) this!

My iphone touch screen isn't working? - 1

My iphone touch screen all of a sudden stopped working? It will either not let me click on anything or if I click on one thing at say the bottom left anything at the top right goes crazy and starts clicking on apps itself repeatedly, I then have to switch my phone off then back on to stop the issue then after 5 minutes it happens again. There's no cracks in my screen, I haven't dropped it either, but I've had my phone less than a year so it still has a warranty will Apple resolve the issue without a charge? Also, what is causing the issue?

My iphone won't charge with my usb cable?

I have a usb cable which i always use to charge with my wall charger. Yesterday i wanted to charge my iphone 4s with it but suddenly it didn't work. No alert, no warning; nothing. Then i turned my phone off and i plug the usb cable in. And my phone turned on without i pressed the power button! I know the usb cable is working and maybe the problem is in my phone software. Anybody know how to fix this? What kind of software can fix my phone? Ps: it's jailbroken.
