How to Enable Battery Life Estimated Time Remaining in Windows 10

The power icon in Windows 10 works as a battery level indicator, showing the remaining battery life. In initial Windows 10 releases, the tooltip for the battery icon showed the device's estimated battery life, expressed in hours and minutes, in addition to the percentage which was calculated in real-time. However, in recent builds this feature is disabled by default, so here's how to enable it.

In recent Windows 10 releases, the battery power icon tooltip only contains a percentage of battery life remaining, without the estimated work time. Microsoft has removed the other information because it’s just inaccurate. It can change dramatically depending on your tasks, after you change the screen brightness, or when you connect/disconnect a Bluetooth device, or enable/disable Wi-Fi.

After enabling the feature, you will see the battery life estimated time remaining in both the Battery Saver flyout and tooltip.

The feature can be enabled with a Registry tweak. You need to sign in as Administrator before proceeding.

To Enable Battery Life Estimated Time Remaining in Windows 10,

  1. Open the Registry Editor app.
  2. Go to the following Registry key.
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power
    See how to go to a Registry key with one click.
  3. On the right, modify or create a new 32-Bit DWORD value EnergyEstimationEnabled.
    Note: Even if you are running 64-bit Windows you must still create a 32-bit DWORD value.
  4. Set its value to 1 in decimals.
  5. Now, delete the following two DWORD values: EnergyEstimationDisabled and UserBatteryDischargeEstimator.
  6. Restart Windows 10 to apply the changes.

You are done.

    Hello!

    This feature does not work on my machine. I log in as an administrator and reboot in vain. It doesn’t work anywhere else. Is there another solution?

    Best regards,
