iPhone 15 hot when charging

Hi everyone


Iphone 15 gets quite warm while charging with apple 20W adapter, on the left side it is difficult to even touch, as soon as it reaches ~75% battery level, it starts cooling down and this problem is not observed after 75% charging (even at 90 or 100%), only till 70-75% phone gets heated.


Did anyone observe the same? software is updated.

I noticed my Iphone 15 overheating when using a USB-C / USB-C cable. I could charge my phone from 1 to 100% in about 90 minutes. However it got very warm, especially early in the charging cycle. That kind of heat can't be good for the battery over time. So, I tried charging with a USB-A / USB-C cable and charged my phone from starting near 0%. No over heating, but much slow charge cycle (about 4 hours to fully charge). That's not a big deal for me since I usually charge my phone over night or plug it in when sitting at my work desk. I'm just thrilled that my phone is no longer heating up while charging (and hopefully the phone battery will thank me by lasting longer).
