Troubleshooting a Draining iPhone Battery After an Update:
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.
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...
C. Troubleshooting the Battery:
D. Report this to Apple
Do your Part: Provide Apple with feedback on this, letting them know about this issue. Apple may not get back to you directly, but the more feedback they receive on this, the more they will know what is occurring, and what bug fixes to include in updates to come.
