How much storage is left in an 16gb iphone after updating it to ios9? - 1

Its based on your phone… Update with the iOS device you have will make it easier. I will update my answer when you update the question.

Update 1: It uses 1.3GB far smaller than iOS 8 with 4.5GB. But what's left depends on your device.

Does it means 1.3gb(ios9)+4.5gb(ios 8)=5.8gb in total?

Around 12 GB will be usable after formatting, default apps, and the iOS installation.

You might have around half of your RAM. You get Leo Privacy Guard as it will hide images and videos and it will also lock applications that you don't let anyone to access.

Check your storage usage to find out.

I believe it takes a few gb

  • 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?
  • Why won't my iPhone 4s charge properly after ios9 update? I updated my iphone4s to ios9 a few days ago and ever since then, it hasn't been charging properly. I'll plug it in and it'll go up to 80 percent and it won't go past that. I've had it plugged in all afternoon (about 8 plus hrs already) and it's still at 80 percent. Is there a way I can fix it? Is it because of ios9?
  • Why is my iPhone 4 telling me I have no storage left? My iPhone 4 is constantly telling me I have no more available storage left.

Can someone help me figure out what to do?
