Q. Is there a way to always show the battery-life indicator in the Windows 10 taskbar?
A. If the battery icon has retreated into the hidden icons section of the taskbar’s Notifications area or disappeared from view altogether, you can restore it quickly. Right-click the taskbar area and choose Taskbar Settings from the menu; on a tablet, press and hold your finger on the screen for a few seconds to get to the menu.
When the Taskbar settings open, scroll down to the Notifications area. Click or tap either “Select which icons appear on the taskbar” or “Turn system icons on or off.” On the next screen, tap the button next to Power to On from Off. (If you wish to display icons from third-party programs, choose “Select which icons appear on the taskbar” to turn on notification icons for apps like Dropbox or an online backup service.)
Once you have restored the battery icon to the taskbar, you can tap it, click it or hover the mouse cursor over it to see the percentage of battery life left on the current charge. The Windows Store has several free or inexpensive apps available to display the charge percentage and other details; open the Store icon from the Start menu and search for “battery.”
Mac users who want to display the battery icon in the top menu bar should open the System Preferences by clicking its icon in the desktop dock, or by selecting System Preferences under the Apple menu in the top-left corner of the screen. In the System Preferences box, click the Energy Saver icon and then turn on the checkbox next to “Show battery status in menu bar.”
