Smartphones screens are now larger while batteries don't keep it up. For this reason, we need to make an effort by keeping track of those features that leak battery most. The jewel of the crown of battery draining is, of course, screen brightness. Lux is an app that comes to automatize brightness preferences depending on the environment.
It works by linking the brightness of your surroundings (ambient light) with the brightness of your device's display. The ambien light is obtained via the light sensor installed on your device (usually above the display). From the dashboard you can produce linked samples (profiles), toggle astronomer and night modes and access to preferences.
Likewise, you can create different levels depending on the amount of ambient light that camera catches, which is quite util for a more accurate performance. There are other extra features like: keeping the brightness 100% while charging, a handy widget for an easy management (enable/disable automatic mode, switch between profiles, etc.)
The main catch is that its free version is almost a demo since it is quite restricted. Anyway, the app is worth and if after giving it a go you like it, you can upgrade to the paid version which costs just AU $1.49.
Lux isn't your ordinary brightness app. It intelligently adjusts the brightness of your display based on the environment you're in. If, for example, you step into a dimly lit room, Lux will automatically lower the brightness of your display to make it not only comfortable to read, but to also preserve battery power.
Lux provides the option to automatically adjust the backlight at fixed intervals (periodic mode), when a change in environment is detected (dynamic mode), or when the phone wakes from sleep. It's also possible to adjust the backlight manually. Simply disable automatic mode and you can use it like a traditional brightness tool!
Perhaps the best thing about Lux is that you can teach it how to behave. If the backlight is too bright or dim for your liking, simply open the provided Dashboard, adjust the brightness slider to the level you desire, then hold the link button. Lux will use this new 'link' as a reference in future.
Give it a go! I want you to test Lux for more than the 15 minute refund period offered by Google. I understand that some devices may not have the best quality light sensor, and that you may need more time to play around with settings. If you find that Lux doesn't suit you after the 15 minutes is up, you can request a refund within a week of purchase via e-mail - no questions asked.

Comments and ratings for Lux Auto Brightness
The app is awesome now. I've checked it out every so often over.. A year or so? But it finally got me to switch from screen dimmer. This is full featured! Quality made app, good job devs. Really good job. Unfortunately screen overlays slow my N7, not Lu
Great idea, but kills the battery. I've tried different settings, but whether I use the phone or even if the screen is off and the phone is sleeping, it still shows it using anywhere from 15-40% of my battery. How do I fix this?
I love this app.
Of the three android phones I've had, lux does not play nicely with my HTC One. Example (most annoying). I'll be inside, my brightness is adequate. Then I walk outside, LUX hits 10,240 and 100% brightness yet my back light is so dim I can't see my screen.
Much better than the stock behavior
I love the notification, so I can quickly make changes. Themes for the dashboard would be great!
Why does it keep getting wake locks and draining battery when brightness is set to "on wake"? It should only check brightness once when screen on...but keeps increasing wake lock counter almost every second when screen is on...needs refinement...
