Battery health is not showing off

Hi Mohammad7308,

Thanks for reaching out about the battery health of your iPhone. We can help with this. We see you came from this article: About recalibration of battery health reporting in iOS 14.5

Where exactly are you seeing this? Have you reached out to the place that replaced the battery to ask about this yet?

If not, you may want to do that next.

If you need to Contact Apple Support, you can do so here.

Take care.

Who changed your battery? If ANYONE other than Apple or an Apple Authorized Service Provider, they do not have access to authentic Apple Parts, so Battery Health will never work on your phone again.
