Troubleshooting iPhone Battery Draining 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. Apple recommends you get a new battery when the Battery Health reaches below 89%. So, see if it’s time for a new battery.

  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: This seems to be a commonly reported bug in these forums. Question is: "How many people have let Apple know about this bug?"  Apple wont get back to you directly, but the more feedback they receive on this, the more they will know what bugs are occurring, and what needs to be fixed. Apple will know nothing of your issue, if you don’t report it to them.

Giving Feedback:

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