I've noticed that when the tablet is idle, the battery percentage reported by battery-info does not change. But as soon as I wake up the tablet and run anything, the next percentage will be much lower, especially if the tablet has been idle for a long time. I don't know whether the original battery-status program had the same behaviour, but I'm going to check.

Tso: Is this the issue that you are describing? If not, please send me the output file from battery-info by private message.
