My Galaxy note20 5g started having its screen blacking out when reaching specific temperature.
I do admit that i used my phone alot while charging and gaming. it started happening last night my phone screen would randomly blackout but i could still hear sounds and press things pressing the power button on and off would sometimes work to show the screen but if the phone is hot(due to charging or playing a game) it would keep blacking out. I tried cooling it using a phone cooler. It worked on making it not blackout but if it gets hot again it started happening again. Im not really a tech guy so i dont know what to do. As unreliable as chatgpt is i asked what could be a problem and it told me that its a battery problem and my phone is protecting itself from damaging itself due to the battery being bad.
That's exactly what your phone is doing. You've been overheating a 6 year-old device by gaming and using it while it's charging. Why wouldn't the battery be failing?
