How to Use Dark Mode on iPhone and Android in Canada

Dark mode flips your phone screen from bright white backgrounds to dark backgrounds with light text. Many people switch it on in the evening because a darker screen feels gentler in a dim room, and it can make notifications less glaring when you check your phone at night. It will not fix every annoyance on your phone, but it is one of the easiest settings to try, and you can turn it back off in seconds if you do not like it.

On both iPhone and Android, dark mode is a system setting. That means once you turn it on, most built-in apps and many popular apps will follow it. Some apps still keep their own theme setting, so you may need to adjust one or two apps separately. This guide walks through the phone setting first, then the schedule option, then the common app settings.

Step 1: Turn on dark mode on iPhone

Open Settings, then tap Display and Brightness. At the top of that screen you will see Light and Dark. Tap Dark and your system apps, menus and keyboard will switch right away.

If you want your phone to change on its own, stay on the same screen and turn on Automatic. You will then see two choices: Sunset to Sunrise, or a custom schedule. Sunset to Sunrise follows the time of day where you are in Canada, so your phone goes dark in the evening and light again in the morning. A custom schedule lets you pick your own start and end times, which suits shift workers and anyone who keeps unusual hours.

Step 2: Turn on dark mode on Android

Android phones vary a little by maker, but the path is close on most recent versions. Open Settings, then tap Display. Look for Dark theme, Dark mode or Theme, depending on your phone. Turn it on, and your system menus, notifications and supported apps will switch to dark backgrounds.

Samsung phones add one extra stop. Open Settings, then Display, and you will see Light and Dark at the top. Tap Dark. Google Pixel phones use Settings, then Display and touch, then Dark theme in most recent versions. If you cannot find the setting, open Settings and use the search box at the top to search for "dark" or "dark theme". That search usually lands you on the right screen in one tap.

Android also lets you schedule dark mode on many phones. In the same Display area, look for a schedule option next to the dark theme setting. You can often choose sunset to sunrise or set custom times. If your phone does not show a schedule option, do not worry. Leaving dark mode on all day works fine, and you can still toggle it by hand from Quick Settings by swiping down from the top of the screen.

Step 3: Make your apps follow the system theme

Most popular apps now follow your phone theme by default, but a few need a nudge. Start with the apps you use most. In WhatsApp, open Settings, then Chats, then Theme, and choose System default if it is not already set. In Instagram, open your profile, tap the menu, then Settings, then Theme in most recent versions, and choose System default. In Gmail, open the menu, tap Settings, then General settings, then Theme, and choose System default.

For apps that still stay bright, open the app settings and look for Appearance, Theme or Display. Choose Dark or System default rather than Light. If an app offers no theme setting at all, it may simply not support dark mode yet. That is common with smaller apps and older apps, and there is no phone setting that can force every app to change.

Web browsing deserves a quick check too. In Chrome on Android, open the menu, tap Settings, then Theme, and choose System default. In Safari on iPhone, websites follow the system theme only when the site itself supports it. Some sites stay white even in dark mode, which is normal and not a fault with your phone.

Step 4: Set a schedule that suits your routine

A schedule keeps you from having to remember to switch themes twice a day. Sunset to sunrise is the easiest choice for most people in Canada, because it tracks the long summer evenings and the early winter sunsets without you touching anything. If you work nights, a custom schedule makes more sense. Set dark mode to start when your shift starts and end when you get home, so your phone matches the light around you rather than the clock on the wall.

Try the schedule for a few days before judging it. Some people love dark mode at night but find it harder to read outdoors in bright sun. If that happens, keep the schedule but add a manual toggle you can reach fast. On iPhone, add Dark Mode to Control Centre through Settings, then Control Centre. On Android, the dark theme tile lives in Quick Settings when you swipe down from the top. One tap flips the theme without digging through Settings again.

Step 5: Fix common dark mode annoyances

If text looks washed out in one app, check that app theme setting first. A single app stuck on Light while the rest of your phone is dark usually means that app is set to Light on its own. Change it to System default and it should fall in line.

Frequently Asked Questions

Does dark mode save battery?

It can help a little on phones with OLED screens, where dark pixels draw less power. On LCD phones the saving is much smaller because the backlight stays lit. Use dark mode for comfort at night rather than as a battery fix.

Why do some apps stay white in dark mode?

Some apps have their own theme setting set to Light, and some smaller or older apps do not support dark mode yet. Open the app settings, look for Theme or Appearance, and choose System default. If no such setting exists, that app simply stays bright for now.

Can I schedule dark mode for sunset to sunrise in Canada?

Yes, on both iPhone and Android in most recent versions. On iPhone, go to Settings, then Display and Brightness, turn on Automatic and choose Sunset to Sunrise. On Android, look for a schedule option next to the dark theme setting in Display settings.
