What is at issue here is that the reported battery status during charging is an 'estimate' and appears to be a rather high estimate. The only way to get an accurate status while the unit is charging is to disconnect the AC power from the unit. Ideally we will fix this so we get a more accurate 'estimate' but until then we should document how to get an accurate battery status for 'charging' units.

I will try to summarize how the system works. The first issue that one must understand is that it is not possible to determine the battery life when a battery is being charged. Only by putting a battery under a load can the life of a battery be determined. Not possible? I don’t understand this on its face. The unit is normally plugged in. If the battery is at 10% and plugged in, then one would expect the charge indicator to slowly increase. I assume this is the case? If what is at issue here is simply the fact that the reported battery status is inaccurate and will always be inaccurate, lets document this fact so people know what to expect. If it is possible to increase the accuracy, then lets fix it and tell people the timeframe for this to happen. Ken
