Surface Pro 3 LGC Battery Degradation

I'm not a Microsoft employee, but I've been on this thread a while and might be able to give you some insight into what others of us have been experiencing.

1st, Microsoft will not respond.  They will not tell (at least not here) what to expect cost wise and if you tweet to them about this or pay to talk to a tech (you need to pay) they'll tell you the price which is somewhere between 450 and 500 I believe.  Most of us naturally find this price point obscene and unacceptable.

2nd, this problem is most likely software related (That is to say I cannot speak directly to your issue, but for most of us this will have been software related) and that Microsoft is in fact responsible for causing it.  They will not outright say this to you, but if you look at the history of the little bits they have said I believe they just about admit to this.

3rd, sending this into Microsoft just gets you a refurb sent back with an additional one month warranty.  Part of why those of us experiencing this issue find that unacceptable beyond the price simply being too high is the fact we have no faith that the unit we would receive would not simply put us in the same situation two months later.  Microsoft's handling of this problem has given us zero assurance to the contrary.

The question of if this is legal or not has been tossed around by several of us, but I do not know that anyone has taken the step toward actually attempting to sue Microsoft yet.  I know I would be happy to join a class action lawsuit at this time.

Hope this helps

Looks like roughly 1000mWh lost peer week which will drag my battery down to 0mWh in about 5 months dpending on how many times I need to charge it.  Microsoft will either make lifelong proponents or opponents with this mess. They need to just suck it up and start recalling devices. I have an i7 512gb device that's way too expensive to turn into a brick in a couple of months.

I too am now having battery issues on my Surface Pro 3, Windows shows a battery level of 58%  when it is plugged in.  Although it states "not charging". As soon as the cable is unplug my Surface shuts off and will not turn back on until I plug in the charger again. I took it to Best Buy, where I purchased my Surface.  I am three (3) months outside of my warranty so I can pay a third party to replace the internal battery (Approximately $450), or by a new Surface.  

Very disappointing!  Sounds like this has been an issue for a while and MicroSoft has done nothing to advise their customers, nor have they provided a reasonable solution.

I'm not a tech person so I do not know how to review the battery history.  However, I was able to work remote perfectly fine without connection to the power supply throughout the week, then over the weekend the issue noted above occurred.  The following Monday, I received the news from Best Buy Geek Squad. 

I am a very unhappy customer at this point..

So, MicroSoft, if I was to send my Surface back for repair, what would be the actual cost?  Is replacement of the internal battery, the only option?

I am in the same situation on a fresh install. Every since the new update I have been seeing inflated charge counts and loosing a few mWh per charge. Very troubling for such an expensive device. At some point MS needs to just face the music and fix users devices. I was seriously considering upping to the next Pro or a Surface Book but this has me concerned. It is not like a regular laptop where you can just buy a new battery. I have devices that are older, but little to no battery degradation.  

After a burning it until shutdown today and giving it a 5hr charge, it dropped to 37,688 for today (not pictured 11/18)....sigh

I'm back too again. Although technically mine was fixed with the firmware update, I'm not sure if it was fully fixed. I've been working on it for exactly a week now and i'm noticing something odd. So my battery went from recognizing only 5000 mWh to now 39,000 mWh but each time I use this during the day and charge in the evening, I noticed a couple of hundred mWh is unusable. so in this past week, I went from 39000mWh down to 38000 mWh and seems to progressively get lower each day I use it. Any thoughts? Oh and I forgot to mention my cycle count is currently at 436. Yeah, I use it a lot.
