How would I know? I've no idea what mobile MUA you use, or even which
mobile platform it is. I use the Gmail app on Android and it does what
I want, but there are several others.

Of course it won't download again and again. Syncing means it keeps the
local and remote versions in sync. Note that this also means that if
you delete something on one then it will delete it on the other. If
that's not what you want then you don't need syncing but archiving,
i.e. essentially a backup. Which you can also do with IMAP but may not
be so directly supported by the MUA.

The mobile MUAs I've seen will typically show only the latest mails by
default. You can also usually configure them only to show new (i.e.
unread) ones.

I've never seen a manual for an Apple mobile device. I'm not sure there
are any. It's supposed to be obvious (their words, not mine).

Apple Mail on mobile devices supports IMAP.

I don't know what your specific need is, but I have several family
members who are professional musicians and teachers of music and they
are 100% Apple users (phones, tablets and desktops), including
everything to do with communications, music editing, publishing,
publicity and performance. However I fail to see what that has to do
with email.
