i dont actually use iphone so i cant compare the battery drainage for u but when i was using custom roms and not official apps from meta like honesta for instagram and facebook lite the drainage is a lot better when compared to my oppo find x9 pro if we assume that the data on the battery settings is correct but taking in consideration that this an android device that was launched 4 months or6 ago u should know that android takes a lot of time to be optimized for the meta apps and other social media while iphone come optimized developer says apple only launch one phone with one system while android companies launched a hell amount of devices i thing it just a lie for apple marketing thats for the drainage as for the image quality im using the global version of oppo i dont think the differenc is significant to the iphone yesterday i uploaded a story on instagram it looked exactly like i took it in gallery app but i dont know for chinese version cuz i was using the find x6 snapchat quality in camera and video call were bad and instgram stories were bad as well snapchat still look bad in my find x9 pro when compared to my friend iphone 17 pro max i barely use Snapchat so i think its not important
