Day after day, many of us spend dozens of hours staring at the screens of our mobile devices. The most important display parameter, brightness, affects not only the battery consumption rate of our smartphones, but it is also one of the most common causes of eye fatigue. Today we have prepared a list of six Android apps that will help you prevent eye fatigue and extend the battery life of your phone or tablet.
Cobrets (short for Configurable Brightness Preset) is a free app that allows you to switch between different brightness presets using a small (1×1 size) home screen widget. Cobrets has several predefined brightness modes: Minimum (8%), Quarter (25%), Medium (45%), Maximum (100%), Auto, Night, and Day.
You can edit the minimum brightness values for modes: minimum, Cuarter, medium and maximum. Auto mode uses Android auto brightness settings. Night mode sets the brightness to zero and applies a black translucent filter to the screen area, so you get a brightness level even lower than the system default. Finally, Day mode uses a yellow filter superimposed on the display to make it easier on your eyes. Cobrets allows you to manually change the brightness level and settings of the applied filters, including filter colors and opacity levels. Cobrets gives you the ability to directly enable or disable any of these modes, so you don't have to switch between them all.
In some cases, when your device's display is faulty, you can use this app to correct the displayed colors. However, given the price of the displays, it might be easier to change it. For example, the price of the original display for Prestigio from Mobilife is quite affordable. The display can be replaced both in the service center and on your own.
IntelliScreen is a free application that allows you to adjust the screen timeout based on device position, lighting conditions, and currently running applications. The app will first ask you to set the normal screen timeout value, which will be the default. With IntelliScreen you can set any time interval, even exotic values like 2 minutes 15 seconds. You can then set individual application rules. It is possible to keep the screen always on while an app is running in the foreground, or set a screen timeout for each app.
IntelliScreen also lets you use your device's sensors to control screen timeout. You can completely disable the timeout when you hold the device in a certain position (portrait or landscape orientation), which is determined using the accelerometer. You can also use the light sensor. This allows you to automatically turn off the screen when you put your device in a dark place (such as in your pocket), and turn on the screen when the device is exposed to light. However, this option is only available if you decide to upgrade to the premium version of IntelliScreen (€1.99).
Finally, you can choose when your settings are applied: always or only when the device is docked in a car dock, desktop dock, or plugged into a charger.
Lux Auto Brightness is a popular Android app that allows you to easily adjust the screen brightness to the optimum level, thereby reducing eye strain and saving battery life. Lux Auto Brightness is a small slider pop-up that is used to adjust the brightness.
The most interesting feature of Lux Auto Brightness is the ability not only to create abstract profiles such as "Night" and "Day", but to adjust the display settings according to a certain, actual ambient light intensity. By default, Lux Auto Brightness will only adjust the brightness level when the device wakes up, so you won't be distracted by changing screen brightness. However, you can change this behavior and choose from several tuning modes: Ascending, Periodically Dynamic, or Manual.
The Lux Auto Brightness app is available in two flavors. There is a free version of Lux Lite which includes the most important uses. If you like the app, you can purchase the full version of Lux Auto Brightness for $3.80.
Night Mode is a very simple application that will override your system's display settings so that you can dim your screen to below normal levels. Night Mode uses a filter overlay that acts as a dimmer to dim the screen so it's comfortable on the eye. This is especially useful when you're using your phone in low light environments, such as at the cinema or theater. Night Mode is a free app without any built-in ads.
Twilight is an app that adjusts the color temperature of your device's display according to your current location and time of day. Twilight is based on the idea that overexposure to bright blue light can trigger the secretion of the hormone melatonin at night, thereby causing an inability to fall asleep. Bright blue light sources, such as natural sunlight or LED displays, inhibit the production of melatonin in the brain, which signals the body to start the day. The program filters the blue spectrum of your mobile phone or tablet display and protects your eyes with a soft red filter. The application allows you to adjust the color temperature and intensity, as well as the value of the screen backlight level.
Velis Auto Brightness is an application that gives you full control over the automatic brightness settings on your Android device. When launching Velis Auto Brightness for the first time, a simple seven-step wizard will guide you through the initial setup.
The program's main screen displays a customizable curved graph of ambient light brightness on the x-axis, and screen brightness on the y-axis. Drag the red handle to change the brightness of the screen under different ambient light levels. You can save multiple settings at once as different profiles.
There are many other parameters you can adjust using Velis Auto Brightness. You can create a list of applications that will not use existing settings, change the sensitivity of the sensors, and so on. Some additional features (Tasker support, Widget) are available as premium content through an in-app order.
