How to disable performance management after replacing battery
Performance management (throttling) has been enabled on my iPhone 6 (due to “unexpected shutdowns”).
I am pretty sure it needs a new battery (4 years old, charge doesn’t last very long, etc.) and I ordered a replacement battery from iFixit.
Since the new iFixit battery does not support the iOS Battery Health feature, how do I disable performance management after replacing the battery? I don’t want to risk having a permanently throttled iPhone even after installing a new battery.
(I know I can disable performance management BEFORE replacing the battery, but since I have to let the existing battery drain before removing it, there is a risk the phone may re-enable throttling before I can replace the battery.)
