You can check the battery level of your iPhone and Bluetooth earphones all at once!

How do you check the battery level of an iPhone with a notch at the top of the screen, such as the iPhone X? Even if there is, you can't display the percentage, so you can only know the remaining amount roughly, which makes you feel uneasy. You can check the percentage by opening Control Center, but it's a bit annoying.

Speaking of remaining battery power, we are also concerned about Bluetooth devices such as earphones. If the product supports Bluetooth LE (Bluetooth 4 or later), a remaining battery level graph will be displayed next to the remaining battery level of the iPhone itself, but the specific percentage will not be displayed even if you open the control center.

In such a case, let's use a widget. If you register a battery widget on the widget screen that appears when you flick the first home screen to the right, you can check the battery level of the connected Bluetooth device in addition to the iPhone itself at the same time. Moreover, since it has a percentage, you can grasp the remaining battery level of the Bluetooth device more concretely than the bar graph in the status bar.

Preparation is easy, just tap the "Edit" button at the bottom of the widget screen and add the "Battery" widget. There are many third-party apps with similar names, so select the white-on-green battery icon.

In most cases, it is not possible to know the remaining battery level of a Bluetooth device in 1% increments. With Bluetooth LE, the remaining battery level can only be reported to iOS in four stages, so percentages are rough figures such as 100% and 80%.
