Computer crashed when battery appeared to be at 11%

After the update of the 8th March, my computer crashed when the battery had 11% of its capacity. Before that, it could shut down and crash suddenly when the battery was around 4% of its capacity. How can one explain that? Is it linked by an upgrade of xfce4-power-manager? I would be glad if someone could explain this. Here some more information:
