Why does iOS lie about storage space required for updates?

Question

I go to my iPhone settings to install an update. It says I can&rsquo;t install the update because &ldquo;at least 3.92 GB of storage space required.&rdquo; I check my storage space. It&rsquo;s 5.88 GB. Does anyone know what&rsquo;s going on here?

[Preface: No, I don't know.]> Why does iOS lie...Especially with no obvious "...(4) Profit!" reason for Apple to intentionally lie, I'd attribute this to incompetence.There are a number of ways to measure available storage space, before you even get into "GiB vs. GB" sorts of issues. So if it's not too much of a PITA, freeing up more space seems a pretty plausible "First Kludge" to try.
