Why Does My Ipad Pro Battery Die So Quickly. The next thing you can try is an old troubleshooting standby. It turns on Background App Refresh for all your apps by default.

However although this might be a good feature it can drain your battery very quickly. Use only Apple plug and wire. If you go into your settings and turn it off your batter will last much longer.
Make sure your iPhone is connected to a stable Internet connection.
Now open the App Store. This might happen every second or few seconds and sends a constant amount of data which requires more battery power. Once your iPad has rebooted repeat the previous steps and see if the battery drain has returned to normal. Try doing a soft reset on the iPad Pro.
