how can i delete downloaded ios update from iphone settings/general/software update

Yes it does download by itself for some strangr reason. But its less than a 1 gig. a little under 800MB if I recall correctly.

Nope...about 4 on my ipod 5 Typically on a regular device it takes about a gigabyte of space that I saw the previous night and the next morning it was at the five and that's including the one gigabyte that it was already taking up.

I know its been 3 years. However this problem is still going on with new OS updates.

THE SOLUTION:

Step 1: Go to Settings > General > Usage > Manage Storage.

Step 2: Select “iOS 8.0.1.” Because it is over 1GB, it is probably towards the top of your list.

Step 3: Tap Delete Update, and tap Delete Update again to confirm.

This will effectively remove the downloaded update from your device and prevent you from accidentally installing it.

BTW: This guy had a storage problem, and instead of helping him solve it you guys just blamed him for causing it in the first place. That doesn't help anyone...and then by page 3 there were tons of people proving that it wasn't the original poster's fault after all. Keep that in mind when you attempt "help" people in the future. Just answer their question. Don't try to blame them for screwing it up in the first place.
