Dear Dev Team, I am writing to report a severe battery drain issue after updating my Apple Watch to watchOS 11 (22R5318h). Since the update, my watch’s battery life has drastically reduced, going from 100% to 0% in just 4 hours. I have taken the following steps to resolve the issue, but none have been successful: 1. Performed a fresh reset of the watch. 2. Reset my iPhone. 3. Disabled background app activity. 4. Enabled airplane mode and power saving mode. Despite these efforts, the problem persists. My watch’s battery health is at 100%, so I believe the issue is related to the software update. I would appreciate your assistance in resolving this matter as it is significantly affecting the usability of my Apple Watch. Thank you for your attention to this issue. ——————- Update 1: I have rolled back from iOS 18 beta 4 to iOS 18 beta 3 after reading that the update might be causing the issue with the Apple Watch. Following this, I reset my Apple Watch, including the cellular plan, and did not restore from a backup. However, the problem still persists. Additionally, I have noticed that the charging time from 30% to 100% has increased to 3 hours and 23 minutes using a 20W Apple charger.
