Windows 10: Battery full charge capacity is decreasing

Hello there,There is already a question in Microsoft forum but I can't reply it because it's locked: https://answers.microsoft.com/en-us/windows/forum/all/full-charge-capacity-is-decreasing-very-rapidly/396d28dd-a83a-40b5-bd7a-3f53b9cdff93My issue is very similiar, the only difference is that my laptop is Asus notebook A541UJ.Here is the thing: I already bought 2 new batteries and within 5-6months of usage, the capacity goes from 28 000 kWh to like 6 000 kWh, so, my guess now is that the Windows Operating System is not dealing very well with the batteries. One of my latest battery report shows

:)

 

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)

Sure! I'll do the steps again for 3 times. I'll reply with the result.

Thanks!!

 

Battery FULL CHARGE CAPACITY Reset

Yves,

"Full charge capacity" means the capacity that the battery is managing to achieve. It is not a limit set by Windows or anything else; it is merely a reading of what the battery can actually do. You can use the comparison of Full charge capacity with Design
capacity to decide when to buy a replacement battery [I do the same regularly].

Full charge capacity will always decrease over time as the battery wears out. This is a chemical phenomenon not a Windows-imposed characteristic.

Windows display of "Fully charged [100%]" means - the battery is currently at 100% of what it is able to achieve. In other words, "Fully charged [100%]" is relative to Full charge capacity.

Sometimes, you can find that cycling through the battery three times** can improve the Full charge capacity a bit.
On at least one of my batteries, the maker recommends doing this every three months. But doing so is using up even more of its remaining life so you can complete this procedure only to find that you are worse off afterwards.

** In other words, loop through this three times -

• remove the AC power
• use up the whole charge by using the computer
• recharge fully
