412b - I'm not sure You know about that, so I think it may be worth posting. As You for sure know, current % of battery charge - both in bme or bq_27200 - is calculated incorrectly, as simple one-line function. One of TMO members - dr_frost_dk - created custom algorithm to calculate battery capacity % from actual voltage, based on real observations using his advanced charging/discharging equipment, and research from other sources. It's proven to be much more accurate and I haven't heard of anyone claiming that it's inaccurate, as opposed to stock algorithm. He distributed his custom work as QueenBeecon widget. Would You be interested in incorporating this to Your nice applet? I would LOVE to replace Nokia stock applet on status menu with - finally - real measurement, but unfortunately, it seems to be little out of my skill to modify Your code in such a way.
