You need to start disconnecting components until you’ve figured out what is causing this issue. An easy way to do this is to simply put the screen at max brightness and set the Auto-Lock to Never. Start by testing the telephone as-is to set a benchmark . A normal should deplete ~4.5 hours, depending on the condition of the battery.

Then disconnect the Rear Camera and do the same test. Then do it again with the Front Camera removed etc. until you figure out which part is causing the rapid battery drain. Always remember to disconnect the battery prior to disassembling or re-assembling the innards.

Does the wifi function fine on the phone without issues? I found out that in most cases the problem is caused by the wifi chip overheating due to short circuit.

This happens after dropping the phone, a common issue that occurs on the 6s models where a component on the board gets damaged relating to wifi.
