Battery Degradtion : Surface Pro (5 , 2017) (I5, 256 gb)

Hello,

I just wonder if some of you who own this version of Surface Pro have the same issues like mine as in below:

ISSUE: Battery at full charge drastically degraded and swingsConditions observed lately:-The battery runs out within 1-2 hrs just by browsing websites/Youtube (tested on both Chrome&M. Edge)

-To fully Charge, takes only around 20-30mins (Est. full charge not accurate)

-Battery sometimes drops by a ridiculous amount E.G. by 20-30% in 1 sec.After checked with Battert Report run in CMDAt Designed Cap at : 45,000,

My Full Charge history as below (Noted that i tried to reset the windows and all previous history is gone so this is what i remember)

First bought (Jan,2018)

Full Charge 2018                                 : around 40,000 0 44,000 

Full Charge 2019(Early months)          : Starting to drop to 35,000

Full Chrage as of the last few months : 25,000

Full charge as the last few days of notice: Swings from 22,000 to 9,000 life cycles at 383 

Now i cant use it outside without charger. This is very frustating while working**.**

As my device is out of warranty, after searching online, the onl way is replacement at 500USD which seems ridiculus to me just because of battery. I bought this expensive device for the reason of long-term use. this is just a year and a half. Shouldn't it last for 4-5 years for its price?

If you have the same issues and any solutions/suggestions, feel free to share and discuss.

**Update 1 8/19/19:**I can't turn on. I lost my files those i didn't back up. I don't have any other computer to use.

Update 2 8/22/19: I just bought a new PC just to work. I cant wait for 1-2 weeks (Send to another country as  there's no microsoft HQ in Thailand) and spend 500USD for just battery replacement.

I kinda gave up and thought it was my fault back then. Now, if you have the same problems. Please up vote.

Update 3 9/1/19:

Seems like my battery is completely dead after testing at a computer shop.

Conclusion:

I am not a hardcore user. In less than 400 cycles, battery (all 4 cells) is dead.

The battery life of my surface pro lasted less than 2 years.

That means you have to pay 500 USD every 2 years. (Could have used this money to upgrade lol)

Maybe 2 in 1 tablets/laptops are not ready for practical use.

Maybe other brands are geting better.

Why do we have to refurbish/replace the device for just a battery which shouldn't cost more than 50 USD.

P.S.

For those who cant even turn the device on,

It's either the circuit is broken duee to defect/unfunctional battary 

OR

The battery is completely dead

Worst case = both.

    Per Barb's suggestion, I had re-installed the battery driver, and as I have promised, I am posting the following observations after a few rounds of charge/discharge cycles:

    Immediately after re-installing the battery driver, Batteryreport reset the battery state to 100% at what it thought was maximum capacity, 34,290 mWh. (The theoretical capacity is supposed to be 45,000 mWh.)

    20:15:40 Battery changed Battery 100 % 34,290 mWh
    20:15:40 Active Battery 100 % 34,290 mWh

    During the first discharge, the % remaining reported by the battery icon was depleted at what I thought was a reasonable rate; however, the machine's power cut out at about 70% after about 2 hours of looping through Youtube in Edge. It simply lost power without first going to sleep.

    In the following three charge/discharge cycles, Batteryreport reported very different capacities after the battery had been fully charged:

    08:25:10 Active Battery 101 % 33,950 mWh
    19:24:46 Active Battery 84 % 30,240 mWh
    14:05:08 Active Battery 135 % 35,930 mWh

    However, regardless of what the fully charged capacity was, in each round of discharge the machine always lost power after approximately 2.25 hours on YouTube only. The battery state reported by the battery icon (% remaining) basically had no correlation with anything at all. That means judging whether the battery is working correctly by using the battery state reported by the battery icon is useless. More importantly though, each time when the machine's power cut out, Batteryreport indicated the battery should have more than half the capacity left. On these three discharge cycles, the capacity remaining when the machine powered off were: 26,490 mWh, 23,480 mWh and 35,930 mWh. (Most interestingly, on the third discharge cycle, the power remaining when the machine powered off was exactly the capacity it had at full charge.) I think the numbers reported by Batteryreport are completely unreliable.

    Same issue here with a SP6/8gb/256gb.  MS has ALWAYS had  issues with Intel on the surface pro units, can't wait until they ditch them  and/or provide a Snapdragon alternative. 2-3 hours battery life just surfing the  internet and youtube.

    Sorry to hear your SP5 is dead.

    I am sure you have tried the following, but curiously if your SP5 responded to any of them at all?
