Iphone 12 Charging

Double check the battery health status on your iPhone 12. You may have a poor battery condition which cannot provide sufficient power for peak performance. What is the Battery Health of your iPhone? Open Settings ➔ Battery ➔ Battery Health and let us know which percentage you see for Maximum Capacity. Also note what is written under Peak Performance. If your battery's Maximum Capacity shows a value of 80% or less, then it has gone through its lifecycle and therefore should be replaced, according to Apple.

I recently bought an iphone 12 and when I plug in my 20w charger, the battery % drops, sometimes significantly. Then it charges all the way up to 100%. Is this an issue ? Should I be worried ?

You can restart the iPhone if you think you have an issue...

Restart your iPhone - Apple Support

you would expect it to charge to 100% yes
