update 15.8.3. Recently it started to discharge quickly, sometimes it just turns off, although the charge percentage is high. I don’t remember exactly when this happened, or if I dropped the phone before. in June the battery was replaced with a new one, everything is fine with it, capacity 100%. memory 70GB out of 128GB. Using a non-original charger.

The battery is OK, but the motherboard likely is not. At this point, there is nothing more that you can do yourself.
If it is the motherboard....as I suspect....that is an expensive repair....quite a bit more than the phone is worth. The money would probably be better spent on a new phone, since it will not be long before apps require at least iOS 16 to run.

The battery would only be at 100% if it was replaced in the last month or so. Is that the case?
If not, the 100% reading is not accurate.
If the battery was in fact replaced very recently, then you have a hardware problem.....likely the motherboard......with the phone that will require service at the Apple Store.....make an appointment.....or take the phone to an authorized Apple service shop.

When was the last time that you had the battery replaced in the iPhone 7?
What is the current reading for Battery Health?
Settings > Battery > Battery Health & Charging
If it is 80% or less, the battery needs to be replaced
my battery is 100%
In June, my battery was replaced, today I checked the capacity using a third-party application, and it showed 994/1000
thank you
iphone 7 turns off by itself
