I just got my phone back today I shattered the back glass today I had it replaced and when I got the phone back I had a message in Settings saying that the battery was not an original Apple battery does this mean the store I went to Took out my Apple battery and replaced it was one of their own cheap ones??? If so what can I do!
That can happen if the battery was taken out and it "lost contact" with the battery. Not sure what Apple would do if you took it to an aftermarket repair shop. That sort of thing happens occasionally, and as far as I've heard, they only reset the warning if one went through Apple's official repair ecosystem.
There is no way for us to know.
Only suggestion I can make, take it back to them and ask for an explanation.
If they deny it or tell you they did replace it, there is nothing you can do.
Replacing back glass
