Does updating your iphone with itunes ruin your phone? (Iphone 5)?

No not at all but just be aware that the older the phone and the newer the software it will usually slow down the phone very slightly. At the moment I think the iPhone 5 runs iOS 8.4 just fine and I have IOS 9 on my iPhone 5c which is exactly the same software wise then the iPhone 5 and it runs fine so you should be good

  • Will updating my iPhone apps affect my phone speed as how updating the Operating System (OS) will? Currently I'm using the iPhone 5s on iOS 8.3 I know if I were to update my phone to the latest OS I may notice some slowdown on my phone's performance, since it may not have the "muscle" to handle certain functions. Many apps now are optimised for iOS 9 and/or the 6th generation phones. Will my 5s' speed performance slow down if I update my apps? Will the app's performance slow down?
  • Will updating Iphone 3GS to ioS 6.0 ruin screw up my jailbreak? I don't know how to ask this… Sorry if my wording makes no sense. I have an Iphone 3GS, and I want to update it iOs 6.0, but won't that take the jailbreak or whatever off? And I will have to jailbreak it again?
  • Will my cheap iPhone charger from Amazon ruin my phone? I just got an iPhone charger that wasn't apple brand on Amazon for cheap. People are telling me that it isn't going to work or it will eventually start to ruin my phone. I just recently got an iPhone 5 too so I have no interest in having to buy a new one because the charger is going to ruin it. Will the things people keep telling me really happen?
  • Will downloading a new iTunes ruin my old iTunes library? I tried connecting my new iPhone 5 to my iTunes but it said that it wouldn't connect because my version of iTunes was really old (from 2010) and I never updated. It said I need to download a new version of iTunes (10.7 onwards) for it to be compatible with my iPhone. But my question is, IF I download a new version of iTunes, will all my old songs on my old iTunes disappear? Because if I had to re-download my whole library, I would seriously cry. That would take the rest of my life.
