I see this more as a tool for people who notice reduced battery life and want to do something about it. Currently they essentially need to guess if the battery is the issue and get it replaced to find out.

If you notice your battery life shortening, the health check can either confirm that you will see improvement with a new battery, or it will tell you your battery is okay, and reduced life is due to software changes or increased usage.

I get what you’re saying and also encourage skepticism, but in this case the first and second parties are you and Apple.

Thanks. Worked for me.

Took me a while to find the setting under the audio and video section of the settings, because I was constantly looking for it under instance, general or advanced.
