iPhone 15 Pro Battery Drains Quickly After Recent Update

I purchased an iPhone 15 Pro around two months ago, and initially, it worked perfectly. However, after the most recent update, the battery started draining unusually fast. For example, I charge the phone fully before going to bed, and by the time I wake up, nearly 40% of the battery is gone.

When I check battery usage, the main culprits are the home screen and lock screen, consuming about 30% of the battery. This is frustrating, especially for such a premium device. I expect Apple to address this issue promptly with a fix or guidance on resolving the excessive battery drain. This problem should not occur on a phone of this caliber.
