iOS 16.5 update causes battery drain in iPhones, check how to fix

Apple's latest iPhone update, iOS 16.5, is causing some users to experience unexpected battery drain. However, Apple says this is a temporary issue that should resolve itself within 48 hours. When you download a new version of iOS, a lot of stuff happens in the background. Data is optimised for the new software, battery settings may be recalibrated, apps might need patches, and your photos may be rescanned. All of these things use up juice, but it's a temporary problem. If you're experiencing battery drain after updating to iOS 16.5, the best thing to do is to wait 48 hours. If the problem persists, you can check your iPhone's battery health in the Settings menu. If it's below 90%, you may want to consider getting a battery replacement. Apple has a history of releasing updates to address battery drain issues. So, if you're patient, the problem should resolve itself soon.
