I am trying to find information about the system battery history.
Particularly, I am trying to access the history, to push a graph on my metawatch.
I know that I can extends the metawatch manager to listen to battery levels and record them, but this seems a bit superfluous, as the system already does that. Beside, it would only report the battery graph when the manager is running, which is not necessarily all the time.
What I cannot find, is whether we are allowed to access those datas or not, and if we are, then how.
Anyone having info on that?
