The addition of Dark Mode to Android phones happened with Android 10, but you may have already experienced it with a 3rd party app and Android Skin from various mobile phone manufacturers.
The most popular argument about the Dark Mode feature is that enabling this feature has the potential to save a lot of battery power on the phone.
Especially in OLED displays, Dark or Black is not a color that is displayed across the display, it is the time when the display is off, so no battery power is required for the display to function.
However, a recent study has found that Dark Mode does not save as much battery power as manufacturers point out to consumers.
The test was conducted by Purdue University in the United States, where they compared the most popular Google Apps, including Google Maps, Google News, Google Phone, Google Calendar, YouTube and Calculator, with and without Dark Mode. This test has been performed.
They used Google Pixel 2, Pixel 3, Pixel 5 and Moto Z3 phones, using a tool developed by the development team called Per-Frame OLED Power Profiler (PFOP). Each pixel on the display has the ability to measure the amount of power drawn.
It activates the above apps for a minute when Dark Mode is activated and measures how much battery power is drawn by those apps.
Based on the data obtained, Purdue University has come to this conclusion, which shows that when using the auto-brightness setting, the brightness level is between 30% – 40% when the average user is at home. Switching to one saves as little as 3% – 9%, a minimum that users may not even realize.
However, they also point out that when the brightness level of the display is at 100%, only switching to dark mode saves between 39% – 49% of power.
The most interesting thing is that when using light mode with a brightness level of 20% and using dark mode with a brightness level of 50%, the same battery power is consumed.
They point out that most users switch to dark mode to save battery, where the brightness level is increased for easier reading, but often use the same amount of power.
Therefore, these researchers point out that just by enabling Dark Mode, the phone’s battery power saving is not as high as the manufacturers point out in their advertising campaigns.
The study found that when app makers first introduced Dark Mode, there were no tools to easily measure the power consumed by an OLED display, and that the battery would be saved via dark mode, taking into account the power consumption of the entire mobile phone. The people who did that declare.
However, they further point out that they used the tools used in this study to separate and measure the battery power consumed only for the relevant OLED displays.
However, depending on the phone you are using, there may be some changes depending on how you use it, and don’t forget that turning on Dark Mode gives your eyes more protection when using the phone at night.
