Windows 10 no longer shows the estimated battery time remaining after the Creators Update. You’ll just see a percentage when you hover over the battery icon—not a time. Although it has its quirks, you still might want to see it.
Why Did Microsoft Hide the Battery Life Estimate?
This information was removed because it’s just an estimate. It can change dramatically depending on what processes are running, how bright your screen is, and whether you’re connected to Wi-Fi or Bluetooth. Your computer is making an informed guess and displaying an estimated battery life in real-time. It can fluctuate wildly, and Microsoft seems to think it’s no longer useful.
Apple recently made the same decision on macOS, too. By default, both macOS and Windows just show the percent of your laptop’s battery you have left with no guess about how long it will last.

How to Bring Back Battery Time Remaining
To bring back the battery time remaining in Windows 10, you just need to make a few edits in the Windows Registry.
Standard Warning: Registry Editor is a powerful tool and misusing it can render your system unstable or even inoperable. This is a pretty simple hack, and as long as you stick to the instructions, you shouldn’t have any problems. That said, if you’ve never worked with it before, consider reading about how to use the Registry Editor before you get started. And definitely back up the Registry (and your computer!) before making changes.
Open the Registry Editor by hitting Start and typing “ regedit
.” Press Enter to open the Registry Editor and then permit it to make changes to your PC.
