Surface Pro 3 battery degradation

I have also observed the same degradation problem with my SP3 with 114 cycles and battery SIMPLO, but I'd like to share my experience in case it could help to somebody. I have recovered the battery at 100% capacity, after the apparent degradation.

In my experience I have noticed the problem of degradation quite early when arrived to 31mWh of full charge capacity, and it was degrading consistently all days 2% to 3%, It made me aware and then confirm in forums that I was not the only one with this problem and even with cases more advanced of this problem. I used to use the SP3 almost all the time connected to the dock, I used in battery eventually when I needed mobility and at least a discharge once a month as recommended in the manual.

At this point with a maximum charge capacity at 31mWh I took a few actions: a reinstallation of the battery driver, and the most important I change the way of use of the equipment (always leave it disconnected of the electrical power supply or unplugged from the dock after turning it off while i was not using it, for several hours every day) :

First of all, I went back to the previous version of the driver of the battery and reboot, then update it again with the last driver of the battery and restart.

Afterwards I started to always leave it disconnected from the electrical power supply after turning it off or Hibernate, for many hours, basically throughout the night and part of the day.

Then, each day with patience used it only on battery up to 50% or 60% and then connecting it to charge it. While I was doing this I realized that is was taking more time for  loading when arrived to the 99% and when it got to the 100%, the capacity of load was of 2 to 3% more than the charge capacity of the previous day, and I did it during a week, until now  that it reached the 100% of the capacity again.

Attached my battery report where you can see first the degradation, and then the recovery of capacity.

In order to verify, I've tried to use it on battery up to 15% with use of normal light web browsing tasks, eventually some videos, etc. lasting now more than 8 hrs. then charge to the 100% of the normal capacity again.

I hope my experience can help, try it  (I do not know if it can help with a very advanced degradation) and comment and sharing to verify it.

Also I would like to confirm if leave connected to power supply when not is in use is what is affecting the degradation of the battery?

So far, now I have panic of maintain it connected after the charge, at least until clarification of what is the cause of this problem.

I have bought my SP3 in USA and my warranty expires in OCT-2016, but I live in Argentina, so i cannot take it for an Exchange as a first alternative.

I want to try this method, but how can I use my dock and the USB ports on it with the power disconnected?

Welcome to the club! Sorry you had to join as well.

Hello Kridsada Thanabulpong,

Sorry to hear you are still having an issue. Unfortunately, at this point this would have to be handled by our Assisted Supportdue to it being a Warranty/Service issue because you have tried all of the troubleshooting.

Best Regards

That's BS! Everyone that bought these horrible devices are experiencing this issue. It's like Microsoft is taking advantage of the $99 phone call you have to make, and then the $500 purchase for a new battery just so you can pay off the inevitable class action lawsuit. You should be ashamed for ignoring this issue and ripping people off even more for the batteries at 1/3 the cost of the device! Apple would never allow this to happen and I'm not a Mac/Apple fan.

Have your tried the method posted on this forum to recover the battery?
