On any Windows laptop (or tablet), clicking the battery icon in the menu on the taskbar or simply hovering over it will display an estimated usage time remaining, meaning the laptop’s battery will remain. How long will it last before needing to be plugged in? If the battery portion of your Windows laptop doesn’t show the estimated remaining time, then there is a problem somewhere and today’s article will show you two ways to fix it.
While the battery estimate indicator isn’t always accurate and is really just an estimate, it’s a pretty useful feature. By default, this feature is always enabled on Windows devices. But some factors can make it go away on your laptop.
Updating your device’s operating system to a faulty or beta (Insider) version may hide the battery estimate indicator. Inadequate or incomplete OS updates can also affect your laptop’s battery life indicator.
Whatever your case, the problem of estimated remaining battery time not showing up can be fixed.
Windows 10 update
