Windows 10: Full Charge Capacity is Greater than Design Capacity

Okay, so I have an Acer E5-475 and I just bought a new battery pack for my computer as the old one died on me. it was okay for the first 3 days then suddenly on day 4 it died on me while I was at around 20 percent. when I recharged it back until it was full I pulled the plug of my charger then suddenly the capacity went down to around 47 percent. I thought the battery was severely damaged by somehow but when I ran a battery report it reported a 62,000 mWh Full charge capacity where in the design capacity was only about 38,000 mWh. so far I have tried:


1. Calibrate the battery by fully discharging and recharging no luck

2. Calibrate the battery by fully discharging then recharging while the laptop was turned off no luck

3. Reinstall battery driver still no luck so don't push this solution it's very generic

4. find battery calibration apps there are no reliable calibration apps

5. reinstalling the battery not useful tried many times

6. long press power button, battery reset button no luck

7. use another charger no luck


I have tried all the related solutions I could find but nothing worked.

the capacity of the battery was okay lasts me a few hours depending on what I'm doing. but I can't understand why the battery slowly raises the full charge capacity which is now around 82,000 mWh.

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)?

 

Windows 10 battery percentage of design or full charge capacity?

Is the battery indicator in Windows 10 a percentage of the design capacity or the current full charge capacity of the battery ?

ie. if my battery capacity dropped from say, 60mWh to 30mWh from wear, would the indicator show 50% or 100% when the battery is fully charged at its current capacity of 30mWh ?

EDIT: to describe my case, I have an XPS 13 9350 whose battery has a design capacity of 56mWh. over the past few weeks, the battery percentage in windows stops at 55 with "plugged in not charging". running

shows that the current full charge capacity is about 41mWh, meaning at 55% I'm getting about 20mWh on a "full" charge. the surprising thing is Dell Command Power Manager shows my battery to be in excellent health.

 

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?
