How Do I Stop My Ipad Battery From Draining So Fast. So I learn that the iPads battery will drain faster when it is constantly searching for and wanting to connecting to the nearest Wi-Fi or cellular network tower. So goto Settings-WiFi option or Cellular and turn this off.
So the Apple Pencils battery is always going to drain even when Bluetooth is turned off on the iPad. Also you need to check the screens brightness. If Auto-Lock is set to Never your iPad battery may drain much faster because the display will always be on unless you lock it.
If you let the Li-ion battery drain completely and leave in that condition for more than a few days the Pencil battery will be dead and so is the Pencil.
There are various applications running in the background which you are unaware of and cause unnecessary battery drainage of your mobile. This will disable your iPads Bluetooth feature. When you are out your wifi is going to jump from one connection to another trying to find something stable. Check battery usage to determine what could potentially be causing unwanted battery drain.
