Now you can visually see statistics of batteries in the utility with a graphical interface Aptik Battery Monitor. Perhaps you are as I thought, something familiar, you have probably already heard about Aptik before, this is because you could use the tool Aptik to backup and restore data.
Aptik Battery Monitor from the same developer,
What we see on the chart:
The black line shows the battery level
The red line shows CPU usage
The blue line is the selected time period (active).
