Battery stats are weird

Hi
I had a faulty battery, I flashed a clean Android 6 to try systemless root, I got successful but battery stats are so weird afterward. I have changed my battery just now but I'm getting weird stats still.
I tried to recalibrate the old battery to no avail, have not recalibrated the new battery yet.
Any ideas?
PS: I think battery percentage is replaced by voltage (mv) in stats, but why?
