I'm fairly sure there are industry standards I'm unaware of that specify what information batteries provide. On linux I've seen evidence that there are quite a few of these indicators, telling the company, model, capacity, and so forth. But if the phone isn't charging, the first thing to do is determine whether the charger is at fault or the phone. Swapping chargers should tell that much, assuming access to a known-good charger. -- http://totally-portable-software.blogspot.com [Sat Mar 26: "Documentation and Portability"]
