Question № 1: Do you use your operating system’s Dark Mode?
The opening question was whether the participants use their operating system’s Dark Mode at all. A surprising majority of 82.7% said they used it, but again, there is bias in the data toward people who feel passionate about the topic. Presumably the general public’s Dark Mode activation rate is way lower. More interesting are thus the free form answers, where people could express why they use or don’t use Dark Mode.
Of the 82.7% of people (201 in total) who actually do use Dark Mode, a massive majority said Dark Mode was easier on their eyes, interestingly without specifying whether they use Dark Mode exclusively in dark environments or permanently all the time (also see the drill down question). A lot of participants also said Dark Mode was simply elegant and beautiful (reminder, people would frequently write both: that it was easier on the eyes, as well as elegant and beautiful). Some people also mentioned they used Dark Mode because it
consumes less battery on AMOLED screens
. The rest of the meaningful answers focused on reduced screen brightness, improved legibility and contrast, better focus on content, and the fact that switching between dark and light causes eye strain.
Of the 17.3% of people (42 in total) who don’t use Dark Mode, a majority said it didn’t look “right”, which is somewhat of a vague answer, but suggests they gave it a try but were disappointed. Likewise, several people said Dark Mode text was hard to read, again suggesting they at least tried it. Some people were using operating systems where Dark Mode either isn’t available yet or not supported at all. You can see all other answers in the bar chart below.
Question № 2: Would you expect Dark Mode to affect web pages, e.g., by automatically applying a dark theme for them?
The focus of the second question was on the automatic darkening of web pages that don’t ship CSS rules specific for Dark Mode. 64.6% of participants said they would expect Dark Mode to affect web pages automatically, and 35.4% said they wouldn’t expect this to happen. It’s eye-opening to look at the reasons they mentioned.
Among the people who said Dark Mode should automatically affect web pages, the vast majority said the user choice expressed at the operating system level should be universally respected, or even enforced. However, multiple respondents did acknowledge that doing so would go against the sovereignty of the designer. People again highlighted the issue of switches between dark and light causing eye strain. An interesting point was made by some people who explicitly talked about Progressive Web Apps and how they?through an enforced Dark Mode?could be even better integrated into the operating system.
From the people who didn’t expect Dark Mode to automatically affect web pages, the vast majority said a website’s design was the sole sovereignty of the original designer. Respondents were also skeptical that automatic darkening could be done right universally, and the same number of people said it should be a user choice, but not automatically enforced. Some people said it was a “nice to have” feature, and some participants also saw issues around branding and corporate identity, for example, when logo colors would be modified. The rest of the responses are also interesting, but only mentioned a few times.
Drill Down Question: Do you toggle your Dark Mode setting depending on the environment you’re in (dark, light) or based on the time of day (night time, day time)?
The final question was only visible to users who said in the first question that they use Dark Mode (201 persons in total). Of these participants, 25.4% said they toggled Dark Mode based on environmental factors or time of day, and 74.6% said they don’t. Let’s have a look at the mentioned reasons.
Many respondents said Dark Mode looked bad during day time or that they needed to adapt to environmental light, mentioning it was easier on the eyes. Some people said it should be easier to toggle the setting, or that they used another color filter like
f.lux
that toggles Dark Mode based on sunset, or that they only toggled the setting for special tasks.
Very interesting are the results of the people who don’t toggle their Dark Mode setting. The vast majority said they just always wanted Dark Mode to be on, which correlates with people who said they find Dark Mode elegant and beautiful in the first question. Several participants said they were too lazy and that their operating system didn’t offer an automatic option to toggle the setting, which suggests there is potential for operating systems to add this natively, so people don’t have to rely on tools like f.lux. Apart from that, a few people also said they always work indoors or that they preferred consistency.
Conclusions
Getting Dark Mode right for everyone is tricky. Some people say they absolutely need it and they are fine with web pages to not look like their designers created them, and others say it’s an elegant feature, but at best they want web pages to be darkened on an opt-in basis, or maybe not even that. Apple in their
Dark Mode developer documentation
explicitly write the following:
“The choice of whether to enable a light or dark appearance is an aesthetic one for most users, and might not relate to ambient lighting conditions.”
In the Chrome team, too, there are people with different opinions, and other teams within Google that leverage Chrome as a surface for web content through Android Web Views or Chrome Custom Tabs add another level of complexity. The present survey is thus
one
factor in the equation, but definitely not the only one.
One possible solution could be
(i)
for operating systems to add an option to automatically toggle Dark Mode based on environmental conditions or time of day, and
(ii)
for web browsers to allow their users to globally enable or disable automatic darkening (which may well be in contradiction with the system-level setting for people who like their operating system dark, but not web content), with an additional per-site override so they can choose individually if they want to.
