Preventing this Problem From Occurring

Avoid overcharging your iphone. You should never leave your phone on charge overnight or for long periods of time.

How to Stop an iPhone from freezing?

Encountering a situation where your iPhone won't turn on after exposure to the water can be horrible and may leave you in toss for a fix. 


Water and other liquids can create a short in your iPhone 12 motherboard, failing to turn on or function properly. Even a single drop of water or sweat can potentially cause this issue.


To fix your iPhone after exposed to water, use a microfiber cloth to wipe out the liquid on the surface. Next, face the lightning connector downward and gently tap with your hand on the phone to get rid of the water residue inside. 

You can also place the phone next to a fan blower with the lightning connector facing towards it to speed up the drying process. 

How to Prevent a Problem Like This Occurring?

It’s possible that after hard resetting your iPhone 12 to make it turn on, it simply won’t turn off, which needs your immediate attention.
