iPhone 16 Pro Drains Battery Quickly Even When Screen Is Off

I recently purchased the iPhone 16 Pro, and I’m extremely dissatisfied with its battery performance. Despite having a larger battery and smaller screen compared to other iPhone models, the charge depletes rapidly—even when the screen is off. This is unacceptable for a premium device.

I’ve read that this could be related to an issue with iOS 18.0.1, but Apple has yet to provide any clarification or solution. I expect a quick resolution to this problem, whether through a software update or another fix. This situation is frustrating and diminishes the overall experience of using the iPhone 16 Pro. Apple needs to address this battery issue promptly to meet customer expectations.
