Windows 10: Design capacity is equal to full charge capacity in battery report

My battery report is acting very weird... it shows the design capacity equal to that of full charge capacity and both are decreasing over time. Can anyone help?I use my laptop plugged in most of the time.every week I drain the battery to 10-15% for its health so I shouldn't be getting this problem.

Windows 10 battery report - Full charge capacity exceeds design capacity

I've replaced the battery twice on a Sony Vaio SVS15 with an aftermarket brand and have run into an odd result in Windows 10 battery report.

This shows up and slowly increases(full charge capacity) after following each of the battery manufacturer's recommendation to discharge the battery completely to allow software estimates' re calibration. On initial install, the capacities match.

With the first aftermarket battery:

After fully charging to 100%, then unplugging the charger, the battery will reflect 96% within about a minute. It then seems to discharge much faster than the estimates given by Windows. At the 10% mark, the system shuts down unexpectedly, completely drained.

Second aftermarket battery:

Intermittently, it shows 96% and not charging - I can unplug the charger and back in to bring it to 100%. Upon reaching 10% remaining (10 minutes remaining estimate), it'll run for another couple minutes, then lose power.

Are there other ways to re-calibrate a system to properly report battery life, or could these simply be two faulty batteries?

 

Laptop is charging to design capacity, not full charge capacity

I have a laptop (Dell Inspiron 3541) with Windows 10. After running powercfg /batteryreport in PowerShell, I got a battery report (at %userprofile%\battery-report.html). However, the results didn't seem right. Here's a screenshot.





As shown by the battery report, my design capacity is 41,440 mWh, but the full charge capacity is 26,758 mWh (about 65% battery health). However, it also shows that it is charging to design capacity (154%), not full charge capacity.

Some other weird parts of the battery report:




My battery has never drained 80% in 40 minutes. 80% in 140 minutes is a much better estimate.




Over 60 years turned on and on AC in a week? I was running Linux a lot that week, but 60+ years is impossible.

Is this normal (for a Windows battery report)?

 

Battery FULL CHARGE CAPACITY Reset

Wow.

Your full charge capacity is higher than the design capacity ?

That is certainly unexpected.

To me, it means that there is something wrong with
either the design capacity or the
full charge capacity since the design capacity should always be equal or higher than the full charge capacity.

Also, what is odd in your report is the cycle count, which is very high for a new tablet.

All in all, we can see here that there are issues with those managed
battery values, and Windows provides no means of fixing that.

That is the reason for this post, which still stands today without any proper answers.
