About Apple Pencil we will not say much, because it is an auxiliary device about which thousands of articles have been written. It is a very helpful "toy" especially for iPad owners.
Both Bluetooth headset (handsfree) and Apple Pencil, are equipped with batteries proto give the user freedom of movement and not to force the connection to the iPhone or iPad via a data or charging cable. Compared to the iPhone or iPad, we didn't have an electronic display to show on our devices propercent battery charge level. On most bluetooth headsets, we are notified vocally when the battery is low. Some Planteonics handsfree models also estimate the number of hours left until the battery is fully consumed. to Apple Pencil is a bit hard to let us know when the battery is aprowater consumed. It would be an idea to start writing yourself "attention, you have to charge me!" :-)
And if we look more closely at iOS settings and options, we find that Apple Pencil even "notifies" us when the battery is aprodischarged water. Or good… iOS shows us propercent battery power level for all devices connected via Bluetooth to iPhone or iPad.
As we can see the energy level of the battery for the devices connected via Bluetooth to iPhone and iPad
This is possible by adding a widget in Notification Center.
Many users do not use Notification Center, but for this area of fast information and notifications, both Apple as well as others proApplication developers have developed very useful widgets.
By simply sliding from top to bottom from the top of the display, we can access a lot of information without having to open applications. Current weather, proweather forecast for the next few days, quick access to Photo Camera applications, viewing reminders and calendar events, and even the battery power level of devices connected to iPhone or iPad.
To see in the Notification Center what is the energy level of the battery of devices connected via bluetooth, we will have to add the widget here "Batteries".
Add the "Batteries" widget, then click on "Done" in the upper right to save the change in the Notificatin Center.
After completing this step, in the Notification Center we will see how much battery we have available on Apple Pencil, handsfree or other bluetooth device connected to iPod or iPhone.
