Battery drain issue on my iPhone 16 Pro after iOS 18.1 update

Hi all, have recently updated to iOS version 18.1. My iPhone 16 pro has excessive battery drain. I have turned everything off in settings including intelligence etc. Just wondering if Apple are going to release a fix for this. Just purchased it a couple of days ago and if there’s no update then I’m returning the phone.

Troubleshooting iPhone Battery Draining:

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.. Troubleshooting the Battery:

Sorry to hear. Just know that these are just user-to-user forums. We’re just everyday-users like yourself. No one on these forums has any call in your transactions(and that is a good thing, BTW).
