Zflip 7 overheating and draining battery very fast for seemingly no reason

looking through the posts here, and various articles on the internet, i havent noticed anyone else describing my issues combined, its always one or the other. my phone keeps overheating and draining the battery and i really mean DRAINING.

my previous 5 phones or so had capacity of 5000mAh so i thought 4200mAh wouldnt be such a difference but apparently it is. on all my previous phones i could charge them to 100% before going to sleep and wake up to a 98% charge, but the flip 7 drops from 100% to 60% overnight, and its REALLY hot even though nothing is being done with the phone. sometimes i need to charge it up to three times a day. i have been regularly clearing the memory by closing all the apps, turning off all networks when they arent being used, enabled developer mode to turn off animations for less strain on the graphics, but nothing seems to be resolving this issue. one day the phone is completely fine and the other day i realize how warm my pocket is getting, even though i havent touched the phone in hours, so i take it out to cool it off. i dont use the wireless charging at all, only cable.

i have no idea what to do at this point. has anyone found some stupid background process that they turned off to resolve this issue? i am genuinely concerned for how long this phone is going to last, even though ive only had it for 2 months. background process is my guess since it always happens out of nowhere, like the phone is trying to suddenly download gigabytes worth of data
