iPhone 15pro battery problem

iPhone 15 Pro. After updating to 17.0.3, it's worse than before the update. I have to charge my phone twice a day, whereas with my usage on the 14 Pro with iOS 16 and a 92% battery, it used to last over 24 hours. The problem is so severe that in my opinion, without carrying a power bank, the phone is currently not suitable for use. Not to mention that these issues will undoubtedly impact the battery's lifespan in the future. I've tried everything, including restoring the phone to factory settings and setting it up from scratch without restoring from a backup. I've disabled background app activity and removed all widgets, but there's been no improvement. Apple do something about this 😞
