Windows 10: Battery capacity rapid drop

I have a 4-month-old MSI Modern laptop with core i3 10110u 128Gb storage 8Gb ram. Very much base model type business laptop. I noticed recently my battery life was significantly less than it was the first month or so. Doing a battery report I noticed full capacity was now 31Wh vs new was 39Wh. MSI support suggested doing a battery calibration which I did, but another report after that showed the same loss of capacity. Now I am starting to think maybe the battery is defective, or is not charging discharging correctly? What are the criteria for the PC maker to determine the battery needs to be r

Sudden battery drop to zero

Your battery has dropped in capacity to 40% of the original designed capacity.

The assumption is that it was of very bad quality in the first place.

The apparent drops from ~50% will be due to further deterioration of the capacity after the most recent calibration point.
Hence no warning as this assumes accurate calibration. It would reach zero capacity at some higher percentage which is what you see.

The solution is to get a new quality battery.

 

Full charge capacity of battery decreased

Repeat the steps Dave suggest you other three times.

Also you can uninstall and reinstall battery from device manager before each charge. You can do that:

1. Press WINDOWS + X

2. Click on "Device Manager"

3. Click on "Battery"

4. Right click on your battery

5. Click on "Uninstall device"

6. Repeat steps 4 and 5 for each element on battery list

7. Click on "Detects Hardware change" (monitor icon)

 

Acer battery won't charge

What if the battery unremoveable? Should I disassemble and remove it? also there is a switch underneath the case and around the RAM slot that prevent the laptop to turn on when the case is open and without the charger. Is that the same as removing the battery? although when turned on with charger, the laptop still see the battery. Thanks

I took the report, the design capacity was 41.440 mWh but full charge capacity is now 25.752 mWh. Is it that bad? Before this happened I believe HWMonitor also show the same number with 38% Wear Level.
