Troubleshooting iPhone Battery Draining:

I. Battery Drain Info:

Being downgrading is not an option, troubleshoot the battery. The iPhone battery will drain, unless it is plugged in and charging. With lots installed, the charge would be slower. As for how fast it would drain the battery, that would depend on the Battery Health and the volume (sound) you use.

1. Go Here: iPhone Battery and Performance - Apple Support
2. Scroll Down: to "Your battery's maximum capacity"

II. Troubleshooting the Battery:

• iPhone Battery and Performance - Apple Support

• Charge and Monitor the iPhone Battery - Apple Support

• About the Battery Usage on your iPhone - Apple Support

• About Optimized Battery Charging on your iPhone - Apple Support

• If you see "Your iPhone Battery may Need to be Serviced" - Apple Support

• Use Low Power Mode to Save Battery Life on your iPhone - Apple Support

Once your iPhone has been updated then it cannot be downgraded to a lesser iOS version.

Downgrade is not supported.

Maybe you should change your iPhone 6 battery, it's about 7 years old.
