Recent reports from iPhone users have highlighted a concerning issue: unexpected and rapid battery drain on iPhone 15 and some iPhone 16 models following the iOS 18.0.1 update. This problem has sparked discussions across various online platforms, including Reddit and Apple Support Communities.
Users have reported alarming battery depletion rates, with some noting their devices dropping from 100% to 60% charge by midday, even with minimal usage. More surprisingly, many have observed significant battery loss during standby mode, suggesting a potential background process issue.
The problem appears to be widespread, affecting not only the latest iPhone 16 series but also older models running iOS 18. Some users claim to be experiencing only 50-60% of their previous battery life compared to earlier iPhone versions or iOS iterations.
In response to these issues, iPhone owners have attempted various troubleshooting methods. These include disabling features like ProMotion and Always On display, turning off background app refresh, and even performing complete device resets. While some users reported minor improvements after these adjustments, many continue to struggle with persistent battery drain.
The release of iOS 18.0.1 and the iOS 18.1 beta brought hope for a resolution, with a subset of users noting improvements. However, these updates have not provided a universal fix, leaving many still grappling with the battery life problem.
As the root cause remains unclear, affected users are eagerly awaiting a comprehensive solution from Apple. It's anticipated that a future iOS 18 update will address this widespread battery drain issue, restoring normal battery performance to affected devices.
In the meantime, iPhone users experiencing this problem are advised to monitor their device's battery usage, adjust settings as needed, and stay tuned for official communications from Apple regarding potential fixes or workarounds.
