Random restarts on iPhone 7

First time encountering this problem. I suspect the aftermarket battery which I replaced myself. I was able to use phone fine for about 6 months after replacing battery. I've read that cpu caller 0 is related to battery or battery connector.

Can someone confirm this is battery related by looking at the logs? Thanks a lot.
