Cant you just calculate this by yourself using something like Devcheck?
I know its third party but still -its not that hard.
The main thing I worry about is automatically lowering the battery's voltage after x numbers of cycles.

All Japanese makers (Sony, Sharp) have had this for years.

Google is just being lazy once again, and I wouldnt be surprised if Samsung follows suit. This is one feature that Apple got right since they first introduced it.
