Hi,
Welcome to Windows Family!
I am afraid the time remaining varies widely, so it may give an inaccurate time remaining. Instead, Microsoft came up with the Battery level percentage directly on the Taskbar.
If you still wish to show the time remaining, the following should help.
In the Windows search,
Type cmd, right-click it, and choose Run as Administrator.
- Execute the following commands exactly as written:
reg delete "HKLM\SYSTEM\CurrentControlSet\Control\Power" /v EnergyEstimationDisabled /f
reg delete "HKLM\SYSTEM\CurrentControlSet\Control\Power" /v UserBatteryDischargeEstimator /f
reg add "HKLM\SYSTEM\CurrentControlSet\Control\Power" /v EnergyEstimationEnabled /t REG_DWORD /d 1 /f
- Restart the computer to apply the change.
I hope this information helps. If you have any more questions, don't hesitate to reach out.
Otherwise, please take a moment to rate the answer. Wishing you good luck!
