Should I update my iPhone 5 to iOS 9?

I've done some research and it should be okay, many sites say that if you have iPhone 4s maybe not and if you have iPhone 5s or later, it'll be fine, but I haven't read any sites mentioning iPhone 5. I haven't heard any incidences where an iPhone 5 has had any problems but my dad doesn't want me to upgrade. I really want to though…

Nope i can't really think of why not but don't you don't need it plus it will only take up space

I've updated an iphone 5 that I use for software testing and it works fine.

Apparently problems may occur if you have not been keeping them up to date and you try to go straight from ios 7 to ios 9.

Back it up using itunes, just to be safe - at worst, you would have to reset and restore it.
(But i don't personally know of anyone that's had problems, over a dozen or so iphones / ipads I know of).

There are many reported issues here and some of the upgrades are dodgy - your dad may have a point you don't want to brick it.

Updating a device will always prove beneficial for you. If you can update it do update it. You may also install Leo Privacy Guard to make your device totally secure.

  • Update stopped during ios update own iphone now phones broke I connected my iPhone 4 to my computer (iTunes) and started doing the update through iTunes. About five minutes into the update iTunes in my computer stops working, causing the update to of course stop working. Now my phone will not turn on. On the screen it is black with the 'charge symbol' as if it were low on battery and an iTunes symbol. I have tried turning my phone off and on, but of course it didn't respond.
  • Should i update to ios 8 or stick with ios 7 on my iphone 5? Cuz from experience i know ios 7 is really slow on iphone 4. So just wondering if anyone already updated to ios 8 on their 5. Is it worth it, any issues with the speed
  • Should I update to iOS 7? Or Stay with iOS 6? I have an iPhone 5, and I was wondering whether iOS 7 is a worthy upgrade from iOS 6, and if the features are really that compelling or not. Or Should I stay with iOS 6?
  • Should I update my iPhone 4 to iOS 6 or leave it on iOS 5? I'm currently using iOS 5.1.1 because I didn't want to lose google maps (which I use a lot) to shoddy apple maps but I've seen a google maps app on the app store now so do you think I should update to iOS 6? And what are the benefits?
