Missing Battery Indicator works by looking for your laptop battery, and gathering data about it. How many cycles your battery has been through, which relates to overall quality of your battery, temperature which helps with how optimally it discharges, in addition to the time remaining.
Rounding is weird, why?
In the status bar, we round off the minutes, so we show "4h" (4 hours) even though your time remaining is 4 hours, 50 minutes (closer to 5), because you don't have 5 hours left. We think it's better to warn you that you have 4 hours left, instead of saying you have 5, so you take action sooner to avoid losing any work.
Please send us a message if you have questions, problems or otherwise just want to say hello.
Never be left without charge in your battery again
