2 Best Ways to Fix Windows 10 Battery Time Remaining Issues

2 Best Ways to Fix Windows 10 Battery Time Remaining Issues

On any laptop (or tablet) running Windows, by clicking the battery icon in the taskbar menu or by hovering your mouse over it, you should see an estimate of remaining usage. In other words, how long your laptop should last on battery. If your Windows laptop’s battery section doesn’t show an estimate of “ time remaining, ” there’s a problem somewhere, and we’ll show you two ways to fix it.

Although the battery estimate indicator is not always accurate and is actually only an “ estimate ”, it is a pretty useful feature. By default, it is always enabled on a Windows device. Certain factors could make it disappear on your laptop. Updating your device’s operating system to a bug or beta (Insider) version of Windows could hide the battery estimate indicator. The Windows 10 Creators Update contained this bug. An incorrect or incomplete operating system update could also break your laptop’s battery life indicator.

Whatever the case, the remaining battery time / estimation problem can be solved. Sometimes it sucks not to know how long your laptop would last before needing to charge. If you’re having trouble estimating your Windows laptop’s battery, one of the fixes below should help put things right.

After installing the update, check if the estimated battery time for your laptop now appears when you hover over it or click the battery icon in the taskbar. While you’re at it, you need to open Device Manager and update the drivers for major components such as the processor, chipset, and graphics.

If all of that doesn’t solve this problem, you should try the second method below. Although this is a bit technical and tedious, it would make the estimation of the remaining time of your PC’s battery work again.

Adjust Windows registry

The Registry Editor is a tool for making changes to certain hardware and software configuration settings on their computers. To solve the problems of estimating the battery life of your laptop, you must modify two entries / keys in the Windows registry: UserBatteryDischargeEstimator and EnergyEstimationDisabled.

When enabled, these two inputs would prevent your laptop from displaying the estimated usage time you can get from your laptop’s battery. The hack is to delete these entries and create a new entry that displays the battery estimate. It’s very simple to do, really. Just follow the steps below.

Step 1: type regedit in the Windows search box.

2nd step: Launch Windows Registry Editor by clicking “Run as administrator” or simply press the Enter button on your keyboard.
