Automatic auto-dimming when phone gets heated

actually, I am using iPhone 13, 250 6GB. It’s just one year five months older device. I am facing a huge issue from this device like Auto dim screen due to my device is getting overheated like left side of the device near volume key button that frame and behind it is completely getting overheated due to that overheat, my screen is getting auto diming. I really hate this problem and my current battery level is 72. If anyone knows what is the issue, please rectify my problem have been multiple times reset my phone.

hi bro, battery health has reached its limit. and thats the main reason you are experiencing this issue. we have to change battery when it reaches 80%. kindly visit nearest apple service center and change the battery. that will help fixing it.

I consider your response, as I don’t use my device heavily, yet the battery drains quickly. I’m wondering if this could be due to an issue with the motherboard or excessive heat, which could be causing the rapid decrease in battery percentage.

no bro. its clearly battery efficiency related issue. its unable to give enough power to your usage as its degraded. so changing battery only will let us use the phone normally again.
