Downloaded iOS 17.0.1 and its using excessive amount of battery

I have an iphone 12 and ever since I got the official iOS17 update my phones battery has been draining very fast and once it gets to the bottom 20% it jumps around between 12% and 6%. Is there a way to uninstall the official update and go back to iOS16?

iPhone 12, iOS 17

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:


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.

  1. Go Here: Feedback - iPhone - Apple
  2. Select: "Bug Report" for the "Feedback Type"
  3. Comment: that this all began after installing an update. Include the URL of this thread
  4. Proceed from there as necessary
