ubuntu phone: In System Settings: graph in battery chart missing

[Hans-Peter]

On my BQ Aquaris 4.5, OTA-9 it happens very often, that the graph is missing. Eventually it starts showing again, but only from current time. History is lost.

Thanks, there are some known issues that could explain what you describe, one is that data points are only displayed on charge level changes, so there might be an important gap between the axis and the first point if the battery is stable for a long time

That may very well be the case, because my phone is in deep sleep most of the time. That leads me to another issue: My phone may show 23% battery for 2 days and then, suddenly is dead because the battery is emty. Is this on you radar, too, or should I report another bug?
