I'm assuming you're referring to the part marked with WTF in your screenshot. The apparent delayed start of charging is likely due to a problem in battery-eye graphing. The way the graphs are currently drawn has major inaccuracies around areas where phone (or the data logging daemon) is turned on or off while connected to charger, or if the percentage goes to zero for a while until the charger is plugged in. I'm looking to fix this for next version of the app.

Definitely just plotting the graphs in same view would be rather simple. The problem would be to to somehow scale the y-axis meaningfully (all three values are in different units, and have different scale), and communicating the scaling to user.


For anyone asking for features, please post your feature requests to the tracker at project's garage page rather than (or in addition to) posting them here (You'll need a garage account though):
https://garage.maemo.org/tracker/?group_id=1292

It's much easier for me to manage requests there, instead of looking around for them in the forums
