Automatically Change Screen Brightness in iOS When Plugged in With 'BrightnessPlug'
Brightness is an important part of any device with a back-lit display. Sometimes the screen is just too dark and sometimes it’s just too bright. In addition, the display is also one of the most power-hungry pieces of hardware in your iOS device – so people tend to keep the brightness down to a minimum in order to preserve their phone's battery life throughout the day. But, who wants to keep manually adjusting their screen brightness when they are connected to a power supply? – There is no reason to keep your brightness low when you are connected to an active power source during the day. Additionally, a brighter display helps you see better without straining your eyes in certain situations
A new free jailbreak tweak is now live in Cydia called BrightnessPlug

. With BrightnessPlug, you can set a value for your screen brightness that only takes effect when your iOS device is plugged into a power source. This means that you won’t waste battery when you’re not plugged in and you will be able to see your screen much easier when you are plugged in. The tweak works with Apple's sync cable, docks, and other third party connectors.
Since the device always charges faster than the device can use its own energy, using maxed out screen brightness won’t keep the device from charging, nor will it slow down the charging process. The tweak is also very simple to use as it comes with a simple preferences pane (shown above), which has nothing but a slider for choosing the brightness level you want the display to use when you plug your device into a power source.
As soon as the user disconnects from the power source, the tweak automatically re-adjusts the screen brightness so it matches the settings you have set in Apple’s default brightness preferences pane.
The tweak is useful for people that use their iOS devices near the charging location and the tweak is also useful for dimming the screen brightness while plugged in and charging at night so that your iPhone’s lock screen notifications (these illuminate the screen) don’t wake you up when your iPhone is sitting next to your face on your bed stand. As a free tweak that does a great job of solving an issue, it is worth a try.
