Batterystats.bin gives the system the hi n low points of the battery. I believe it tells the phone ( or plays a big part in telling when to stop charging the battery or when its to low to continue working , where it then shuts down .. I think we would be better off with a script the deletes it on shut down ,so its forced to refresh it self on the next run .. Remember clearing the batterystats.bin is just the same as conditioning the battery , which is just refreshing the full and empty points....
