iPhone SE (2016) iphone getting hot on wireless charger

[thanhtam23]

recently i notice my phone cannot be fully charged on wireless charger, i usually charge before sleep and when i wake up the phone is hot and battery stop at 80%
i tried to replace the charger, test with another phone, remove casing, turn off optimized battery performance
it’s still the same, the phone getting hot around 80% and stop charging
i’m on latest ios 13.5.1, anyone having same issue?

Sorry I don't have that issue. I use a wireless charger with a cooling fan at home and a disk when I'm at work and both work as should. And I have a case on my phone as well. Have you tried powering of your phone and restarting it? Even a forced restart?

I have tried two wireless chargers and mine get hot. Heat is the enemy of a battery's life. I quit using wireless.

If you use a wired charger from Apple, does the same 80% rule come into play?
Good question from @BugeyeSTI, hand considered that if you have a non fixed schedule or don't need 100% for days age, it may be out smarting itself.

Also, bare phone to charger or do you use a case which may be making the process work harder.
