Mine the other way round, brightens when plugs into power source, but only marginally, enough to notice it though.
think is probably a characteristic of the electronics

Hp probook 4520s charging time more brightly .battary off time darknessly

Laptop screen is normally brighter when it is connected to the charge adapter. When the laptop is running on the battery it is usually a little dimmer to save battery power, you can adjust the screen brightness even on battery power. To adjust the brightness hold down the Fn key and press one of the function button keys it maybe the F7 or F8 key it will have a symbol on the key to indicate the screen brightness.

I have HP Compaq 6910p and having issue with its battery/changer as laptop screen become bright on battery and uses more battery then normal.

Right click the battery icon next to the clock on your taskbar. Select "Power Options" At the bottom, there is a slider for screen brightness. Slide it left to dim, slide right for brighter.
If you want your laptop to automatically adjust the brightness based on whether it's plugged in or not, click "Change plan settings" next to the currently selected power plan (usually Balanced).
On the new screen, there are 2 sliders. I would recommend setting the Plugged In slider to max and the On Battery slider to about 1/2 to begin with. Then adjust them to personal preference.

The screen brightness changes due to plug in or battery power

This is quite common actually I see it a lot. There really isn't any reason, it seems that when on batteries it trys to save power by Dimming Down, but it often just mucks up.. I always now set it via the keyboard keys. whenever I change from power adapter, to battery.

Powerbook G4 screen getting dim.

Did you already increase the brightness through the control panel? If not it is software driven and that can increase your brightness.

HP Pavilion laptop battery life

Maybe your battery aging, battery's life is about a year (I also use laptop)
If you often use external power supply, take out the battery, it will extend battery life, because the battery's life depends on the times of charging and discharging.
You say the screen is brighter, some laptops have a default value of setting LCD screen in computer system, you can adjust the brightness youself. Press "EN" key, and press "upward" at the same time, the screen can be brighter.
Or you can get a replacement battery,
I don't know what's the brand of your laptop, I have bought a battery online, the quality is OK.
