> it seems that it still runs hot according to some reviews I've seen on the yt.

Never noticed it being even warm in normal use, consistently cold.

> this is especially true during hot summers

Sounds like not a phone problem -- very high screen brightness and/or direct sun would make any phone hot.

I am not an idiot, I am not keeping my phone on direct sunlight neither do I run on "very high brightness". The phone runs hot on normal circumstances, and in summer when the temperatures are getting higher it becomes unbearable. I hope you understand now.

I've misread that you're having consistent problems across different models, sorry.

If it's just 10 Pro, then google says Qualcomm was having bad years (I've heard about Snapdragon 888 fiasco, but apparently it extended to 8 Gen 1 in OP10)

Oneplus 15 uses a Si/C battery like other higher end Chinese phones currently. It doesn't get hot during normal operation (I don't play games on it) and since I don't use fast charging, for now it looks like it will work for a long time. Still get easily 2 days on a 80% charge.
