Troubleshooting iPhone Battery Draining After an Update:

A. Battery Drain Info:

Unfortunately, there is no way to determine why, nor when, the Battery Health decreased. 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.
