Troubleshooting a Draining iPhone Battery:

A. 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.

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

B. Verify the Baterry Health Percentage:

Apple recommends you get a new battery, once the Battery Health reaches 80% or lower. When the Battery Health is 80% or lower, it is time for a new battery. Unfortunately, these if no way to know how, nor when, then percentage decrease occurred. So see if it tine for a new battery...

1. Go To: Settings
2. Tap: Battery
3. Tap: Battery Health
4. View: [the percentage]
5. Is it 80% or less?  If so, it is time for a new battery.

C. 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

You are welcome.

Excellent! Thanks for doing your part. It will help many, for certain.

My Battery Health is at 85% and has been so for 6 months. I'm sure it will decrease soon, and then it will be time for a new update.
