laptop battery life cycle and capacity
laptop battery life cycle and capacity

For those of us working from our PC battery and apparently using the new video movie watching on airplanes, I wanted to double check my battery performance.   With all this tech I still find it interesting I have to use my 1990’s cmd line and directory knowledge to run diagnostics on my PC. Apple people are probably laughing.

By the way I love the www.aa.com ‘s idea of allowing people to use their own laptops and personal computing devices to watch videos while on planes.  It makes so much sense.  From an energy point the plane saves weight by not installing extra wires and displays into each seat.  Especially since most people have their own displays with them.  Kudos to american airlines or whoever made the switch.

So I found this posting for testing batteries and other items for Windows 7 and it still works in windows10. Checking battery consumption – good article

  • Oh by the way the cd %userprofile%/Desktop line does not work, ( I think they assume you understand that you have to get to the proper directory)
  • you have to use cd statement to work your way to your user directory, which is
  • then cd desktop and then run powercfg -energy and
  • it will create an html which you can read in your browser.  C:/users/#yourusernamedirectory#/desktop/energy-report.html – where #yourusernamedirectory# means your name here

My battery still looks good as it is still charging to over 92%. Dividing 46816/50464 tells me that my battery last full charge was to +92% which is good.  Also my cycle count is only 96 and the article below says it should take 300 to 500 cycles to fall below 80%.  It will be interesting to see.

Some articles I googled, in case anyone was interested.  I know this from work I did way back in the 1990’s and even in 2010 plus work.  But some people don’t, just because it never came up.

And from a sub article they say 80% is not good http://batteryuniversity.com/learn/article/capacity_loss

Lithium- and nickel-based batteries deliver between 300 and 500 full discharge/charge cycles before the capacity drops below 80 percent.

Well anyway I just wanted to share this in case anyone else out there was wondering how their battery charging was doing.

Cheers and Happy Battery Life,
