How to analyze Windows battery report
To bring up the battery report, double-punch it.
A tab with information about your laptop battery will appear in front of you.
The first and most important data you need are at the pages beginning.
CYCLE COUNT gives you a rough idea of how much life your laptop battery has left.
For some laptops, it may be 1000 cycles, and for others 300.
For example, my ASUS ROG GL552VW battery is rated for over 600 cycles.
If you scroll further, you will see detailed battery usage statistics for the last 3 days.
There is also a diagram attached to this as well.
Here you’re free to see over what period the battery drained by how many percent and capacity.
If you scroll further down, you will find detailed battery usage history.
Its usually 7 days.
The same table is available for capacity in the middle of the report.
It is called Battery capacity history.
Below that is a table called Battery life estimates.
The At Full Charge column shows the maximum charge the laptop battery can currently hold.
You should also realize that these statistics may become inaccurate over time.
