On average the Battery Health with 304 Charge Cycles would be about 93%-94%. Those are simply averages with the expected battery life of the battery being 1000 Charge Cycles before it needs to be replaced based on normal usage. Battery health drops are not linear meaning some months it will not drop at all and some months will drop more.
You are only 2% points below the average that is expected for normal use, so no I do not see where you have any hardware damage that would point to a cause. That does not indicate a defect as advised to you previously in the other post. Apple updating the software for you after an appointment would be the first thing they would have done, whether you had reported a heat issue or not. That is the basic step performed and also recommended by Apple for users to do themselves.
As far as overheating, that is only the case when you see the thermometer on the screen and the device will not let you use it until it has cooled. down. Not sure if that is what you are referring to or if you just experienced the device being warm that normally occurs due to the increased demand from Cellular Data and Video Calls. Your device also gets warm when fast charging and you may get a notification when it reaches 80% that it will cool down before continuing to charge. That is normal and expected.
For proper Battery Charging habits, I recommend to use Optimized Charging and charge your phone all night, every night. The battery will be prematurely damaged when allowed to continually run out of a charge, but it will not be overcharged due to the charging management. There is no indication from your post of any thermal damage to your device that was alluded to in the previous AI post. Remember AI Chatbots are programmed to be your "friend" and will simply agree with you to gain your trust, and sometimes that is at the expense of providing you accurate information.
