iPhone SE 3 dropped, overheating and automatically withraw battery..

I dropped my iphone SE 3 2022 and it completely shattered its front touch screen and its backglass with visible damage to wireless charging coils. Luckily, it does work but, noticing how it gets hot easily, using or without using it, it also automatically draws battery even not using it.

Any idea what causes this problem? I wanna know what are the things i should consider before I took it to the repair store. Thanks
