Does dark theme really save battery? Study shows it does, but only if certain criteria is met
Dark mode has arrived to phones and computers during the recent years - as a huge wave. The prpoponents of the dark mode have always emphasized the fact that using dark mode saves battery compared to traditional light mode. But is it really true?
Rsearchers at Purdue University put the claim into a real test, using six of the most popular Android apps, in various usage situations, In order to test the dark mode's superiority, researchers installed six most popular dark mode-enabled apps from Google Play store: YouTube, Google News, Google's own Phone app, Google Calendar, Google Calc and Google Maps.
All of the tested apps are pre-isnatlled in millions of Android devices and each of them have more than 500 million installs each on Google Play store.
Dark mode does not save battery if your phone display uses old technology
First and foremost, the dark mode wont save any battery if the phone's display is old. Specifically, phone's display must use OLED (or AMOLED) technology in order to benefit from dark mode, at all.
In OLED screens, when a specific area in display is black, the display in that particular area is actually switched off, completely. So, if majority of the screen is showing completely black color, the vast majority of the screen is actually switched off - thus, saving battery.

Once the champion of speedy Android updates, the rollout of Android 11 has been a struggle for HDM Global who manufactures Nokia branded Android phones. After missing deadlines one after another, Nokia 5.3 finally gets its official Android 11 update.
Google is expected to release new Pixel smartphones later this fall, and while that is still the case, we've already got some looks at the new devices.
