To calculate wear as a percentage you need to knowbasic battery capacity (indicated by the manufacturer) and the value of the last full charge. For example, the first number – 5000, second – 45 510. Therefore, you need to do the following: (50000 – 45510)/50000 = 0.0898*100 = 8.98. Rounding will result in 9%.
Additional battery health information can also be obtained by typing powercfg /batteryreport at the command line.
