What to do if it doesn't work?

If the update still doesn't download after enabling low power mode, try:

1. Restart your iPhone.

2. Temporarily disable the SIM card (remove the physical card or deactivate the eSIM) and connect via another device's hotspot.

3. Use the method with USB connection to PC (described below).

3. Update via USB connection to Mac or Windows (iTunes/Finder)
