System-wide Dark Theme in Android Q is superb, but what are the benefits?

If you love and use Night Mode in your Twitter app, for example, you already know what to expect. A system-wide Dark Theme means a dark theme implemented in every menu of your Android phone. And this is coming in Android Q. We imagine you cannot keep calm because of the excitement.


An early build of Android Q says that “dark mode is an approved [Android] Q feature.” This is good news to many Android enthusiasts who have been clamouring for the feature for a while.

It is interesting that Samsung has baked what looks like a system-wide Dark Theme into their new One UI custom skin. Seeing that One UI is already rolling out along with Android Pie to a select number of Samsung phones, the Korean manufacturer just might have beaten Google to it. But them Samsung has consistently beat Google to a number of cool features on Android. For example, you will remember that Samsung phones had Split Screen before Google added it to Android OS.


Note: I said, “just might”. We will have confirmation soon enough as users report on their One UI experience. See what I did there? In the meantime, the option to ‘Set dark mode’ is found under Display settings in the current Android Q beta build.

Benefits of system-wide Dark Theme

In the meantime, we take a look at the benefits of having a Dark Theme on a mobile phone.

  1. Easier on the eyes. A dark theme is easier on the eyes, as it dumbs down the glare of white light. The results include you being able to read longer and more comfortably, as eye strain is reduced. It is also great for reading in the dark when the glare of the phone screen is more pronounced.
  2. Easier on your phone battery (with a clause). Depending on the type of display technology used, a dark theme can help reduce power consumption. AMOLED screens, in particular, conserve power better with a dark theme. Smartphone displays are the biggest guzzlers of battery power. Combine a dark theme with an AMOLED display and the result should be lower battery drain.If your mobile device uses an LCD or IPS display though, having night mode or dark theme on will not make a difference.

Sometimes, features seen in early software builds do not make it to the final release. We can only pray to the gods of mobile and hope that the system-wide dark theme makes it to the final release of Android Q.

But just in case it does not make it through, I have wondered why smartphone manufacturers have not taken it upon themselves to implement night mode or dark theme in their custom skins. It is great to see Samsung make an effort. The others need to give it a shot too.

It is clear why Samsung would be interested in this – their high-end smartphones use AMOLED displays. Other manufacturers that use LCD/IPS screens may not be as motivated to embark on such a Herculean project. But even without the battery saving benefits that AMOLED display enjoy, users of those other types of screens will enjoy the benefit of less eye strain. So, bring it on, people!

Android OS

There are other new features being expected to arrive with Android Q, but this system-wide Dark Theme is easily one of the most exciting. It might sound like such a simple thing, but if you followed how Twitter users campaigned for Night Mode to be implemented in the app, you would have an idea of how important this is to Android enthusiasts around the world.


In my opinion, the default mode in Android should be a dark theme everywhere. The feature should never have been left out for this long, so this is long overdue.
