2 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.)

I'm confused here ??
You still have your original Apple battery in the phone so all you'll need to do is run it with the setting. Then when you get the new IFIXIT battery install it and you'll be fine.

Replying to Dan -
So, are you saying that the **mere installation** of a new battery will disable Performance Management (throttling)?
Understand, Performance Management (throttling) is currently enabled. I want to make sure it's **no longer enabled** after installing the new battery.
The only place you can disable Performance Management yourself is under iOS Battery Health, which iFixit says is **not supported** by their replacement batteries. If iOS Battery Health is not supported by the new battery, I don't believe there's any way I could turn off Performance Management myself (since iOS Battery Health wouldn't be available after installing the new battery).

I think you're a little confused; what Dan is saying is correct.
Your assumption is that the phone defaults to a throttled position (Performance Management slowing down the phone) if it can't read the battery status (via Battery Health). This is backwards. The reality is that the phone defaults to an UNTHROTTLED position (Performance Management disabled) if it can't read the battery status. So, yes, the act of installing a new battery will disable Performance Management.
Apple's factory-installed batteries support their "Battery Health" feature. SOME, but not all, of Apple's replacement batteries also support that feature. No aftermarket batteries (that I know of) support it.

That is not correct. I replaced my iPhone 7 battery with an ifixit one and it supports the battery health feature. It currently displays 100% as it's new.
