Automatic brightness consumes more, although with shades
When it comes to battery saving, the auto brightness would consume a bit more power because it has to consume resources by having a sensor that adapts brightness according to the environment. Although at first this was very consuming on mobile, now it has improved and you will not notice it too much.
It adjusts perfectly to the lighting conditions, and getting there is something that causes a little hit to the battery, more than having a static brightness level, but sometimes it’s worth it.
The auto brightness is very good because it adapts to different environments without you having to change it and provides you with the better visual comfort. Also, if you have to do the changes by hand frequently, you may consume more power doing it because you have to interact with the screen and perform actions that auto-brightness doesn’t. You also have to take into account the brightness levels that you consider you need, the higher the more it consumes.
Also, the automatic brightness learns from our usage patterns and it adjusts, so in the long run it could consume less, although not necessarily less than the fixed brightness.
If you never change the brightness and it always stays the same, or you make few changes, or it is low, surely spend less with a fixed brightness. It is especially interesting to have dark mode on, since it consumes less energy and takes care of your eyesight. You can also consider a power saving mode.
It depends on many factors
Also depends on panel since in those of cheaper mobiles such as LCD or LED no matter the brightness level the screen always lights up, whereas on newer devices with panels AMOLED and OLED only the pixels that are necessary are activated and the others stay off, so energy is saved and auto brightness is interesting.
It also depends on the static brightness, because if you keep the levels of brightness above 50% this increased energy expenditure will be unnecessary. The manufacturers themselves say so, and also maintaining these levels is much more frequent than you can imagine. If the brightness is low, you will save battery.
The question is that it depends and there is no one-size-fits-all answer. If you want to discover it for yourself, you can do tests, although it is best to opt for the most comfortable fit that interests you the most to you. There are other ways to save energy and the differences are not too great.
Find out how much your screen spends
You can check how much energy your screen uses in all situations from the settings of your mobile. You will have to follow these steps, although they may vary depending on your model:
- Battery and performance or Battery
- information will appear
It may surprise you that the screen consumes so much energy, but it is somewhat logical. What do you think consumes more?
