Cell phone battery life is something of which all its users are very worried, so in this article we will show you how to extend the battery charge of your Android mobile or smartphone.

    Is it possible to save battery on Android by using black wallpapers?

    One of the features we look for when buying a used or new cell phone is that it has the ability to last a long time without the need for charge it constantly .



    Due to this request between Android mobile phones or Smartphones, a small rumor has been generated that if we insert a black screen background, this it would help to extend the battery charge a due to the absence of color.

    However, this totally depends on the type of screen of our mobile or Android smartphone. Those with one IPS LCD screen , in addition to freeing space from the internal memory of the mobile, it is useless to put a black screen background to save battery.

    How black wallpapers work on mobile screens

    You need to know how each type of screen works, as black colors are not output the same in each of them. In this way, we can know if a black background will affect the life of our battery or not. To do this, we will highlight the three most used screens for the production of mobile devices.

    LCD screens

    I'm a screen type consisting of liquid crystals . That is why, when they break, the crystals run. They are the most used screens in cell phones and other mobile devices.


    One of the main advantages of these screens is image quality. Good, it's a much sharper image and more faithful colors. Likewise, the manufacturing costs of LCD screens are very low compared to the rest of the list.


    These screens work by means of an LED plate that illuminates each of the pixels responsible for the emission of color. This results in a disadvantage in terms of energy savings. Since when black colors need to be reproduced, the screen will still be on ; This ignition system is known as a backlight.

    That's why when black screen backgrounds are used on LCD screens; it is not possible to save battery and indeed, they work like any other wallpaper.

    Pantaloni OLED

    It is a much more innovative technology than LCD screens . Well, they work via pixels that are activated individually. In this way you get better energy efficiency and above all you get much brighter colors, with darker blacks.

    This question of black colors is due to the fact that the pixels are turned off to obtain the black color; in this way we obtain the absence of the background brightness that LCD screens have and at the same time reduce the energy consumption on the screen.

    Therefore, in cellphones with OLED screen it is highly recommended to use black screen wallpapers to save battery life.


    Despite this, OLED displays have the disadvantage of produce stronger and less natural colors . They also have a useful life of approximately five years. Blue being the first to fail.

    AMOLED screens

    AMOLED screens have TFT technology, which differentiates them from OLED screens. That is allows them to transfer electricity much faster to any part of the screen. Thanks to this, more lively and dynamic graphics are obtained. For this reason, it is the preferred option for players.


    As for the colors, they work the same as OLED screens. That is, they are brighter and blacks are darker. Therefore, you can save battery even on cell phones if you use black backgrounds.

    On the other hand, the dynamics of these screens do not make them energy efficient. Despite having independent lighting on each pixel, the screen consumes much more power a due to the image refresh rate .

    Likewise, the AMOLED displays have also a shorter lifespan than OLEDs a due to their on-off operation of each pixel. Therefore, normally the pixels are burned one by one.

    Can dark mode help to consume less battery on my mobile?

    Dark mode is it was originally designed to provide visual comfort when the environment is too dark; reducing the white colors of the screen, without losing the clarity of the elements.

    Therefore, the its relationship to energy consumption is not direct . Well, it's all about the application's graphics settings; in other words, the resources consumed remain the same.


    However, as we saw earlier, OLED and AMOLED displays work with individually activated pixels. That's why, in this type of screen, dark mode helps to consume less battery on mobile.

    This same principle does apply to any black color played on this type of screen. It will always result in energy savings.

    However, on LCD-type screens, the dark mode of applications does not work to save power. But alternatively, we can reduce the brightness of the screen ; in this way we can extend the life of the battery.


    How to know what type of screen my mobile phone has and how much battery it uses

    First of all, we will find out how to identify an LCD screen . Well, the first thing to remember is that LCD screens are made up of liquid crystals; therefore, if we press the screen, waves will form around the dark colors.

    Another way to identify LCD screens is attributed to their angles. Now if we try to see the screen from different angles , it darkens and changes color to blue.

    And if we're not sure yet, we can look for a black image and place it on the screen if the black color is not completely dark and remains illuminated; so there is no question that it is an LCD screen.

    Knowing this, we can rule out that a screen is LCD; and therefore it can be OLED or AMOLED. In this case, the difference between the latter two cannot be known at a glance .

    On the other hand, to know how much battery your screen uses, you have to search your phone's settings for "battery usage". Here you can know the percentage of battery your screen consumes . In all cases, the screen is the main consumer of the cellphone battery as it is essential for its functioning.

    Therefore, we shouldn't be surprised by the influence of black wallpapers, as a means of saving battery life.

    Tips to save battery life on my Android phone or iPhone

    In IPS LCD screens it is useless to put a black screen background to save battery , however, we can change the brightness intensity and make the feedback light not as bright. In this way, the battery demand would be lower and the battery charge would be prolonged.

    It also works for AMOLED displays, the overall brightness of the screen would be more moderate as well it would extend the battery life a bit more . However, there are times when we need to activate the brightness of our Android mobile or smartphone yes or yes.

    One of those moments is when we are on the street in the sunlight , as it is impossible to make letters, colors and numbers visible on the mobile phone screen. Similarly we can apply other tips to save battery on the mobile.

    You can try turn off oi vibration toni not necessary such as key tones and vibration when you press the screen. These functions, while they may not seem like it, consume a lot of power from the battery of your Android phone or smartphone.

    Minimize screen lock time, this way you will waste less brightness while not using it . Another tip to save battery on your Android phone or smartphone is to turn off connections while they are not in use, such as Wi-Fi, Bluetooth and GPS or the location of the mobile phone.

    We know that in our mobile phones or Android smartphones we have many of our social networks installed, however, if it is not something urgent, turn off their notifications it helps us to stretch the load on our mobile.

    Try to close applications completely you are not using, do not leave them running in the background, as it still consumes load. Another tip, and perhaps the most important, is to activate the "energy saving" mode; which has most of android mobile phones or smartphones in its configuration.

    How do I know what consumes the battery of my Android mobile or smartphone the most?

    Most Android cell phones or smartphones include a system that detects which ones apps consume more battery , in this way we can limit their use, avoid having them active in the background and even download a lighter version.

    To know which applications consume the most energy, just open the "settings" or "configuration" section of our Android mobile or smartphone, then go to the "battery", "battery use" option and there it will give us some brief statistics on all the applications and the battery consumption they generate.

    Based on the information obtained, we can deduce which applications are the ones that consume the most battery and evaluate if we can replace them with lighter ones or delete them from our mobile phone or Android Smartphones.

    Of course, as mentioned above, the screen will always be the biggest battery drain on your mobile. Since it cannot be eliminated, it is better apply alternatives to reduce consumption.
