Do you mean "battery drain"?

If so, refer to the following...

No. I have not come across this issue.

Troubleshooting iPhone Battery Drain Info:

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

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

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

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

Check the Battery Health on your iPhone.

Home Screen > Settings > Battery > Battery Health

If Battery Capacity is less than 80%, you need to replace the battery

According to Apple:

Optimize iPhone battery charging:

iPhone has a setting that helps slow the rate of your battery’s aging by reducing the time it spends fully charged.

This setting uses machine learning to understand your daily charging routine, then waits to finish charging past 80% until you need it.

1. Go to Settings ➢ Battery, then tap Battery Health.
2. Turn on Optimized Battery Charging.

Click ▶︎ iPhone User Guide.

Apple won’t replace the battery until it reaches 80% capacity.

• Maximizing Battery Life.
• About battery usage.
• Check the iPhone battery health and usage.
• Optimized Battery Charging.
• Use Low Power Mode.
