I have turned off the peak performance capability and the message says "you have manually turned off performance management protection". How can I turn it on again? I do not know whether it is a consequence of the above, but now the colour of my battery sign on the right part of the screen is yellow instead than white..... I have an iPhone SE.....
iPhone SE, iOS 15
Hey federica117,
It sounds like you have questions about the peak performance management on your iPhone. We can understand wanting to look into that further. We want to help.
Check out this article for more information: iPhone Battery and Performance
"Performance management applied
When the performance management features have been applied, you'll see this message:
This iPhone has experienced an unexpected shutdown because the battery was unable to deliver the necessary peak power. Performance management has been applied to help prevent this from happening again. Disable…
Note that if you disable performance management, you can’t turn it back on. It will be turned on again automatically if an unexpected shutdown occurs. The option to disable will also be available."
Thanks!
Peak performance capability
