My XPS 9360 battery seems poorly calibrated or broken (or there is a software issue). When I use the system it drops from 20-something percent to 5-something percent in a heartbeat.
This is some output from upower (sadly I couldn't capture the jump):

So battery capacity is usually calculated using the current volage. Old batteries tend to fail at keeping the volage up, especially under high load... Does it happen during high load? And is it an old battery?
