Battery health drain
I have iphone 12 with 94% battery health but after the update 15.6 it decreased to 90% just in 7 days. I didn’t use my phone while charge and I always charge my phone with original apple charger. Any solutions???

Please call Apple Support. They will tell you that this is normal. Chances are, the battery health was recalibrated when you updated the operating system.
You have to think long term. How old is the iPhone? If it is 12 months old, the Battery Health should be about 88% by now and you report that it is at 90%. That is very good performance.
Check Battery Health again in 3 months and report back to us.
