Battery information showing incorrect time after Golden Gate update

Hi, can anyone tell me why my battery info seems to be 12 hours out? As you can see in the screenshot the current time is 0917 but in the battery level part it is showing 2100 ish. Only started happening when I updated to Golden Gate. Thanks

There appears to be an unusual discrepancy in the battery usage information displayed by your MacBook Air following the update to macOS Golden Gate.


The most notable detail is the approximately 12-hour difference between the actual system time (09:17) and the time displayed in the battery information (approximately 21:00).


This is particularly interesting because a discrepancy of exactly 12 hours does not necessarily suggest a conventional time-zone conversion problem. It could instead indicate an issue involving AM/PM interpretation, timestamp formatting, or the way macOS is recording or displaying battery usage history.


At this stage, however, I would not want to assume that this is a confirmed macOS bug or that the battery itself is functioning incorrectly. There is not enough information to establish the underlying cause.


Apple's documentation explains that Battery Usage History displays battery levels in 15-minute intervals and provides information about energy usage and screen activity. However, it does not document this particular 12-hour discrepancy.


I would recommend checking the following:


  1. Verify your date and time settings. Go to System Settings > General > Date & Time and confirm that automatic date and time and automatic time-zone settings are enabled, where available.
  2. Restart your MacBook Air. After restarting, revisit System Settings > Battery and check whether the displayed battery history has corrected itself.
  3. Check the macOS version. Go to System Settings > General > Software Update and confirm which version of macOS Golden Gate is installed. Check whether a newer update is available, particularly if the issue appeared immediately after upgrading.
  4. Compare the battery history displays. Check System Settings > Battery > Last 24 Hours and determine whether the 12-hour discrepancy is also visible there or whether it is limited to a particular battery information screen.


One particularly important point I would like to clarify:


When your Mac's actual system time is 09:17, does the battery history show 21:00 as the current time, or does it appear to show battery activity occurring 12 hours ahead of or behind the actual time?


If the system clock is correct and the Mac is otherwise operating normally, I would not consider this discrepancy, on its own, sufficient evidence of a battery hardware problem.


If the issue persists after these checks, I would recommend reporting it to Apple Support, particularly if the discrepancy began immediately after the macOS upgrade. Apple may be able to investigate whether this is a software-related issue requiring further engineering attention.


For reference, Apple's documentation on monitoring battery usage is available here:

This is a known and previously reported bug in macOS 27. It started with 27.0, and remains in 27.2.


Bugs should be reported to Apple here:
