Did you know that your phone’s battery life can be prolonged by using apps with darker interfaces? That is true. Extending the phone’s battery life is a combination of many factors. It depends on the technology used to make your screen, and whether the operating system and software on your phone can take advantage of those technologies.
The key lies in OLED technology.
The apparent fact is that high-brightness displays will use more power, and reducing the screen brightness manually can help extend the battery life on any mobile device. However, that is only a small part of the story. Most of today’s mobile devices use two popular display panel technologies: LCD (liquid crystal display) and OLED (organic light emitting diode).
LCD monitors have been on the market for a long time and are the leading technology used to make displays of electronic devices since the transfer from large, coarse CRT monitors to the end of the In the early 1990s, today’s LCDs use fluorescent backlight to emit light through a network of colored pixels, each of which is colored red, green, and blue. Seawater. This hybrid technology is called LED-LCD or sometimes referred to only as “LED screens” for short. This makes the distinction between LEDs and OLEDs more difficult.
The organic LED (OLED) screen combines the pixel grid and backlight of the traditional LCD into each pixel. That means that each pixel is capable of self-glowing. This gives a lot of benefits, such as superior contrast ratio, brighter color saturation, and better performance. But for our purpose of finding ways to save energy for the device, the highlight of OLED technology lies in that, if a pixel on the OLED display is black, that pixel will be Turns out completely, that is, the pixels will not consume power anymore. This is a remarkable improvement over traditional LCDs (and also LED-LCDs), which need to force the backlight to illuminate the entire screen area, regardless of what image is being displayed. Go on.
Phone manufacturers know this very well, and they have found ways to take advantage of that. Motorola is launching the trend with the Moto X phone started in 2012. The phone offers an “always on” display to display the notifications, clock and battery life icons in a single line — minimal white text on black screen. This display uses only a minimum amount of power, less than 1% of the battery life per hour, thanks to the advantage of OLED technology. Today, this function has become very popular in the Android phone world.
How does the darker side of the application save battery life?
With a screen that is almost all black, battery life is remarkable. But, of course, traditional applications will require a relatively substantial amount of text or image rendering, and OLEDs will not save much power unless the pixels are displayed. Marketing a black absolute. Is there a way to “measure the amount of battery life”?
Maybe more than you think. Google has investigated this issue as they develop a dark background for the Android operating system in general and their applications in particular. According to a report that Google provides to developers at their conferences, the new dark background of the YouTube app can save between 15% and 60% of battery life compared to the white background interface. Traditional, depending on the overall screen brightness setting of the device.
This is a significant improvement – enough to make Google decide to integrate dark background for the entire interface of the Android operating system, as well as applications developed by the developer. It’s not too far to say that if the apps you regularly use and the general interface of your operating system move to a dark background, you can extend the battery life by 30 minutes to the one-hour average day of use. It is enough to call an Uber home at the end of the day or kill time while waiting for a taxi. Of course, all these advantages are only available if your device is using an OLED display.
Does my phone have an OLED screen?
Most high-end smartphones on the market in 2018 use OLED displays for a variety of reasons. Samsung uses this type of monitor on many of its most popular phones; Nearly every Galaxy phone (and even a few tablets) has been using this display technology for several years. Google’s Pixel phones also use OLED panels. The most advanced models of LG, Motorola, Sony and OnePlus also use OLED as their central display technology. For Apple, the iPhone X, XS, and XS Max models use OLED panels, but older iPhones and the cheaper XR are not.
If you’re not sure whether your phone is using an LCD or OLED display, search quickly on Google. Search for the keyword “specifications” and the exact name of the line you are using, and you will find a list of device specifications right at the first results. If you see the word “OLED,” congratulations, your device can save significant battery life when using applications with a dark background. If the text is “LED” (without letter O) or “LCD,” unfortunately, you can not take advantage of this.
Which applications support the dark background?
As the battery life of dark background applications is still being researched and measured, there are not many applications that offer this feature. Many Android apps give you different interface themes, and some of them may come with keywords like “black,” “night” or even a record. Also known as “OLED.” However, many essential applications such as Whatsapp or Facebook do not yet support this feature.
As mentioned above, Google is one of the pioneers in applying this trend. With Google-provided apps on both Android and iOS platforms, look for the “Dark Theme” option in the main application’s settings menu and activate it. Google apps that now support this feature include the Phone app, Contacts, YouTube, News, and Messaging, and in the future, this list will likely last longer.
Twitter’s mainstream mobile application has provided a dark interface option. To activate, select your avatar icon. Then, for Android phones, select “Night Mode,” and for iOS devices, select the moon icon.
The native Reddit application supports Night Mode, which is specified only for AMOLED screens and can be enabled or from the main settings menu. The official Samsung browser application, Telegram messaging app and many other small applications also support the same mode.
Version 9.0 (Pie) of the iOS operating system also provides an “evening” interface: You can find it in the Device Theme option of the Display Settings page. Note that this mode only appears in the original Android version of Google, which is installed on Pixel devices and a handful of other phones. Therefore, even if your phone has been upgraded to the latest Android 9.0, you are unlikely to have the option. This feature is limited to only a few parts of the interface. Maybe in the future, Google will release an update to integrate this feature more comprehensive. Another (unofficial) trick to activate this interface is to enable the Invert Colors option – which is available on most phones today – which will help reverse the entire color scheme. On your phone interface; However, it will not be as useful as a feature developed specifically, officially.
Samsung phones support free interface themes, but there is no dark mode or night mode at the time of writing. However, an overhauled interface called “One” will soon be released in the software update for the latest phones and is expected to be installed by default on the Galaxy S10, There will be a night/night option from the very beginning.
What about the iPhone? Interface themes on Apple models are limited, and it does not allow third-party applications to make changes to the interface outside of their claims. But since the company has made great strides in launching a dark background for the macOS operating system on the PC, we can all hope for a dark option that will be incorporated into an iOS update. Future. At the moment, the iPhone has the same color rendering capabilities as the Android models.
Still, want to save more battery? You can change your phone’s main screen wallpaper to black to save battery life even when you’re viewing a list of apps or widgets or when you’re in the standby mode.
What if I do not have an OLED phone?
If your phone is using an LCD screen, you will not feel the increase in battery life compared to using an OLED platform. But after all, to a certain extent, you can still save a little bit of energy with this new dark mode. And the fact is, nothing can stop you from activating them.
If possible, reduce the overall brightness of the phone screen slightly. This may not have much effect on the battery life of your phone, even with the LCD screen, but there are other benefits. If you use your phone for many hours every day (most people are), using a darker overall interface can help you reduce eye strain or get better at bedtime. Blue light filters and operating system tools can also deliver the same results.
In short, maybe next time you go to the store to buy the phone, you should consider the device has an OLED screen. Because it can bring significant benefits to battery life (if correctly set up) and to the whole look, it’s a step up in technology.
