Why I can’t update my iPhone 12mini almost 24hrs still not updating

Hello fidel181 and welcome to Apple Support Communities. It appears you are having some difficulty updating your iPhone 12 mini.

This article has some good basic info on update issues:

If you can't update or restore your iPhone, iPad, or iPod touch

If the update has started and is not completing, the most common causes are 1) the iPhone is not connected to Wi-Fi the entire time 2) The iPhone is not connected to power and 3) low-power mode has been engaged.

Cheers.

Brilliant. Glad to hear you got it sorted. Have a super groovy rest of your day. Cheers.
