Automatic brightness for screen consumes more battery

When trying to save up battery, automatic brightness setup is not the best option at first. The sensors must be working in order to detect changes in brightness levels so it’s an addition to your battery consumption.  However, this requirement has improved with the years and it’s almost imperceptible.

When choosing automatic over manual screen brightness setup, the light level influences how the screen shows to the user. The advantage of automatic brightness is related to the quality of image in any kind of environment. You end up saving battery too because you don’t need to enter the menú for manual customization each time. According to the levels you indicate as maximum or minimum, the phone will change immediately.

The automatic brightness setting also learns from the user patterns. In the long run you can save up battery life in comparison to manual screen brightness. If you never change the brightness level, the manual configuration is the best option.

Automatic or manual brightness screen settings depend on several factors.

The type of screen panel also influences the brightness levels. LCD or LED screens consume more energy and all the pixels are turned on. Most recent panels like AMOLED or OLED only activate the required pixels. This also impacts on the battery life. In newest models the automatic brightness levels are more efficient.

Manual brightness also depend of the environment and our preferences. If you have more than 50% of brightness level the energy cost would be high. When using low brightness settings the battery life extends.

There is no absolute answer for the manual or automatic brightness debate. You must try both options and according to your daily use of the smartphone you will find the most suitable one.
