I just bought an Acer laptop a month ago.

 

this computer ,well , acts kind of weird . the battery full charge capicity changes like crazy (I check using HWmonitor,BatteryMon and powercfg/batteryreport in cmd-all three give the same result).

sometimes it goes up, sometime goes down . from 1% lost in full charge to 3% and back to 1%. 1% in one month means I will lose only about 12% in a year ,but 3% is  a different story . and more ,in each battery report made by   powercfg/batteryreport ,there is a chart called Battery capacity history .Here is one from July 28th :

  Battery capacity history

 two charts showing different results.

and here is battery full charge capacity reported in July 28th

 it's also different from the chart made on July 31st above ?

I have made a lot of these everyday, a few per day, battery capacity always changed when discharged ,like downto 35% or less.

please answer me if this battery is faulty and need replacement .

thanks.
