I posted this idea several months ago but now I have added a second battery saving feature by un-checking two items.
By the way, this works very well with Gingerbread 2.3.6 just like it did with Froyo 2.2.1. For those of you still on Froyo 2.2.1 you can do this now because when I updated to Gingerbread 2.3.6 it was still working fine. The update did not affect it.
You can easily and quickly increase or decrease the brightness of your Charge phone's display screen WITHOUT going into any other menus.
To do this you will first have to turn the Auto Brightness OFF by going to: Settings>Display Settings>Brightness and Un-check automatic.
While you are on this screen also go down the page to the Power Saving Mode at the bottom of the page. There you UN-check the Power saving mode. This turns off that eye in the upper left corner of the display screen that does its own thing to change the brightness of the display. This further saves battery power. Un-checking the Power Saving Mode is an option so if you like it as it is you should keep it.
Now go back to the Home display screen. Next, TOUCH and HOLD the gold colored check mark that is at the top of the display screen to the left of the word Verizon. Hold your finger on the bottom point of the check mark until you see the brown colored notification bar appear under your finger BUT DO NOT pull the notification bar down and DO NOT LIFT your finger off the screen. Just slide your finger left and right. To darken the screen (go left) or to brighten the screen (go right).
Slide your finger back and forth to see for yourself...it is so easy. It couldn't be faster or easier to make your screen brighter when you walk outside into the sunlight or make it darker to save battery power when you' are inside with enough light to easily read the screen.
