If you have tried downloading iOS 8 on your iPhone or iPad which is filled with applications, you might run into a problem. That’s because iOS 8 will prompt you saying that it needs 5 giga bytes of space to download and install the new OS. Though the size of the update is 987MB as shown on iPad and 1.5 GB on iTunes, you have to clear up the space to download and install.
So, how do you make 5 Gigabytes of space? Do you delete all your pictures, videos, or game apps? That is one way to do but I suggest not to do that. Because it’s crazyyy. There is other way around. Just connect your iPad/iPhone to your Mac/PC. Back up your device and then click on “Check for update” button in the iTunes and next when it shows iOS8 is available to download and install. Click on that and you are done.
Happy installing iOS 8😀
