The Power Efficiency Diagnostic Report could be quite detailed and may overwhelm a normal user. This report will analyze and show the status of your battery’s health and point out warnings, errors and other information relating to your battery.

In this battery’s case, you can see that the Design Capacity is 5200 whereas the Last Full Charge shows 4041 – which is almost 22% lower than the originally designed charge. If your battery shows a figure of around 50%, you may expect it to just last for a few more months only.
