Same here. I have iPhone 8. Apple ran a diagnostic and it said that battery is in great working condition. So its def the 10S 14 update. They told me to set factory reset and I did that but my battery is just as bad. I had no background apps running and wifi was turned off/location services too and yet my phone ket draining without any use.
