How long should I wait to charge my iPhone 13 after the 'liquid detected' warning?

If it is an emergency requiring use of your iPhone, you could try an Apple wireless charger.

I assume that the phone did not get wet. The "water detected" message can also appear if the plug is not making good electrical contact with the very small contacts in the port. Sometimes, it is tough to get at the lint. A small flashlight might help.

If you bought an iPhone 13.....shown in your profile.....it is of course not "new".

If you have already tried to remove any lint from the port using a wooden or plastic toothpick a few times, give it another day to let the port dry thoroughly. .

If no luck, make an appointment at the Apple Store / Genius Bar or take the phone to an authorized Apple Service Provider (AASP) so they can run diagnostics on the iPhone.

You can find a list of authorized service shops in your area using this link:

Good luck.

If your phone got wet, you should be worried. Water is often lethal and unrepairable. Do NOT put the phone in rice as that can cause more damage. And if the phone got wet, back it up immediately, in case something worse happens to the phone.

Again, if the phone got wet, it would be advisable to schedule an appointment at your Apple Store Genius bar and Apple can explain your options, but they won't try to fix a phone which got wet.

I just bought this phone 2 days ago and I walked home in the rain a couple hours ago and only had the phone out for like a minute I didn’t think it would damage it this badly I think I’ll just leave it to dry until the morning and hope that works

Using the phone in the rain was not a good idea, to be honest. Whether there is permanent damage, we can't tell. But water and electronics are mortal enemies. Hopefully, it will be OK, but if the warning persists, you need to take to your Apple Store.
