iPhone 15 Pro battery draining rapidly after updating to iOS 26.0.1 and 26.1

I have an iPhone 15 Pro. After updating from iOS 26 to 26.0.1 I'm facing battery problems it's draining very fast, from 50% to 9%. This issue persists even after updating to the latest version 26.1

At this point, you would need to provide additional information:

Battery Health at Settings > Battery > Battery Health > Maximum Capacity.
A screenshot of Settings > Battery, that shows the green battery graph with the last 24 hours option and the top apps consuming the battery. Also make note of the System usage below the apps.

Did you perform a Force Restart after updating?

Press and quickly release Volume Up
Press and quickly release Volume Down
Press and HOLD side button until the Apple Logo appears. This could take up to 20 seconds while holding the side button before you see the Apple logo and you must ignore anything else on the screen during that time. If you do not see the Apple logo, try again as it may take a couple of attempts to get the speed and sequence of the key presses correct.
