After exploring various online forums and discussions, it has been widely reported that excessive battery drain on OS X devices is a result of continuous high-frequency synchronization of Google Contacts in the background, triggered by signing in to a Google account. However, I have not signed in to my Google account, nor have I synced my contacts on any device, including those linked to iCloud. Despite this, my device has been experiencing battery drain without any clear explanation. I have tried to troubleshoot the issue but have been unable to find a solution. I have included a screenshot of my battery usage, which may provide insight into the problem. (https://imgur.com/a/S3Ynlf6)
