Surface Pro 3 battery degradation

My battery output shows 100% charged with 1 hour of battery life remaining. But after the device is unplugged in minutes the charge quickly  goes from 100% to 60% with 30 minutes of battery life remaining and within a few more minutes it goes to 40% of battery life with 10 minutes of battery life remaining. The puzzling thing is the device says the battery is 100% charged but at 100% only 1 hour of battery life registers then the battery actually dies in minutes.

What a piece of junk.

Microsoft has no right to treat its customers like this. They have taken money for defective products and should be doing everything possible to keep people fully updated on how they are going to resolve the fault.

This has probably been linked to here before, but probably worth posting the actual text to keep it in people's minds. Given that we are being given absolutely no feedback from Microsoft about how or when this issue will be resolved please contact these people to get the class action underway.

Migliaccio & Rathod LLP is investigating reports that batteries in Surface Pro 3 laptops are holding almost none of their charge. Consumers have relayed that the laptops, which have Simplo batteries installed, substantially and progressively degrade over time to the point where they are virtually nonfunctional.  While all batteries can be expected to experience reduced performance as they age, the problems that plague Simplo batteries are far worse and appear to only be remedied by a repair costing in the neighborhood of $500.

*Almost every state (and the District of Columbia) has a consumer protection statute that broadly prohibits unfair and deceptive trade practices. If the reports about the Surface Pro 3 batteries prove true, our law firm believes that the sale of the laptops with the defect may have constituted an unfair and deceptive trade practice that may entitle a purchaser to relief. The attorneys at Migliaccio & Rathod LLP have successfully prosecuted several consumer protection class action cases, including a case against Lenovo involving defective laptops, which resulted in a classwide settlement. (Disclaimer: past successes do not guarantee future results).

...and in reference to my surface's battery degradation and the information you are collecting on your own site, here's the pertinent information from my device:

Installed batteries

Information about each currently installed battery

Battery capacity history

Charge capacity history of the system's batteries

And since I ran this report yesterday and the report is discontinuous after the update, my current reported capacity is 8,345mWh (yes, I've lost another Wh overnight!)

Good thought Barb, however the default html file (c:\windows\system32\battery-report.html) does not get moved or re-named into windows.old (would be c:\windows.old\windows\system32\battery-report.html).

So, after the update the old battery-report.html remains in place to be overwritten the next time the default version of the command is made.

For those who want to save historic versions of the file, the default output from the battery report can be sent to a filename of your choosing using:

"powercfg /batteryreport /output c:\filename.html"

Where "c:\filename.html" can be any allowable windows filename in any drive or directory, so could easily be modified to the current date, allowing a file-based record of any changes.
