Battery problem

I'm not a native English speaker, so I'm sorry if there is a grammar problem.  

Hi, i just bought a Dell Inspiron 3593 for about 9 months. The default capacity of this laptop is 42Whrs. Most of the time I use my laptop while it plugged in. Recently, when i switched to battery mode, I found a problem: after each time i'm using and charging it, the battery wear level increasing. But it increased in a very strange way. For example when I shut down and charging it to 93% and stop charging, my full capacity now decrease equal to the capacity of 93%. What is that problem? I tried it 3 times and the wear level increased in all 3 times. Please help me to solve this. Thanks you very much.

(When this report is generated, my battery was fully charged, not just 93%.)

    A battery on a laptop is used to provide power for operating the laptop. Lithium Ion or Li-ion batteries are the most commonly used batteries in laptops and other devices. Dell laptop batteries are designed for each Dell laptop. Power issues on laptops are compounded because a laptop has two power sources: an AC adapter (charger) and battery. The laptop battery provides power to the laptop when the AC adapter is not connected to the laptop.

    If you are experiencing one or more battery-related symptoms that are mentioned below, follow the troubleshooting steps below to resolve battery-related issues.

    • The laptop battery does not hold a charge.
    • The battery indicator LED does not glow, blinks in a specific pattern, or blinks always.
    • The battery is not recognized by the laptop.
    • The battery charge is stuck at a certain percentage.

    If you are experiencing one or more AC adapter-related symptoms that are mentioned below, see the Dell knowledge base article How to Troubleshoot AC Adapter Issues on a Dell Laptop.

    • The AC adapter or charger is not able to charge the battery.
    • The AC adapter is not able to turn on the laptop, or the LEDs on the laptop do not turn on.
    • The AC adapter LED is off.
    • AC adapter-related error messages. For example, The AC adapter type cannot be determined. This will prevent optimal computer performance.
