Windows 10 no longer shows the estimated battery time remaining after the creators update. You will only see a percentage when you hover over the battery icon, not once. Although he has his quirksyou may want to see him again.
Why did Microsoft hide the estimate of battery life?
This information has been removed because it is an estimate. This can change significantly depending on the processes in progress, the brightness of your screen, and whether you are connected to Wi-Fi or Bluetooth. Your computer makes an informed guess and displays an estimate of battery life in real time. It can fluctuate a lot and Microsoft seems to think that it is no longer useful.
Apple recently made the same decision on macOS too. By default, macOS and Windows simply display the percentage of your remaining laptop's battery without planning how long it will take.
How to reduce the remaining battery time
To bring back the remaining battery time in Windows 10, you only need to make a few changes in the Windows registry.
Standard warning: The registry editor is a powerful tool that can make it an unstable or even unusable system. It's a pretty simple hack, and as long as you stick to the instructions, you should not have any problems. That said, if you've never worked before, consider reading about how to use the registry editor before you start And certainly save the registry (and your computer!) before making any changes.
Open the registry editor by clicking Start and typing "regedit". Press Enter to open the registry editor, and then allow it to make changes to your computer.
In the Registry Editor, use the left sidebar to access the following key. You can also copy it and paste it into the address bar of the registry editor.
Computer HKEY_LOCAL_MACHINE SYSTEM CurrentControlSet Control Power
Once here, we will locate and delete some entries: EnergyEstimationDisabled and UserBatteryDischargeEstimator.
To do this, right-click the EnergyEstimationDisabled value in the right pane, select "Delete" and click "Yes" to confirm. Repeat the same process for the UserBatteryDischargeEstimator value.
Then, right-click the Power key in the left pane and select New> DWORD Value (32-bit).
Name your new value EnergyEstimationEnabled.
Double click on the new value, make sure the field "Value data" is set to 1, then click "OK".
That's all we can say about it. Close the Registry Editor and restart your computer. After rebooting, you will see an estimated remaining time when you hover the mouse over the battery icon in the notification area, also known as the system tray.
Download our registry in one click
If you do not want to dive yourself into the registry, we have created a registry hack that you can use. Just download and extract the following ZIP file:
Inside you will find a REG file so that the remaining battery time is displayed when you place the mouse pointer over the battery icon. Once extracted, double-click on the desired file and accept the prompts asking if you really want to modify your registry.
This hack removes the EnergyEstimationDisabled and UserBatteryDischargeEstimator values, and then adds the EnergyEstimationEnabled DWORD we discussed in the previous section. The execution of the hack changes the values of your Windows registry. The other hack included disables this feature and restores the original operation, adding the EnergyEstimationDisabled and UserBatteryDischargeEstimator values to your registry and removing EnergyEstimationEnsabled.
