Schedule Power On/Off
If you keep forgetting to switch your Xiaomi phone off at night or want it ready and running before you even reach for it in the morning, pressing the power button every time gets old fast. MIUI includes a built-in scheduler that turns the device on and off at fixed times you define, with support for daily repetition or custom days. Once set up, the phone handles the switching on its own, without any manual input.
Set Data Usage Warning Level
If you have already capped your monthly data plan on a Xiaomi phone, you might still get surprised when the limit hits without any heads-up. The warning level tells MIUI at what percentage of your data plan it should alert you before you run out.
Set a New Alarm
Waking up on time with a Xiaomi phone means finding the right spot to add a repeating schedule, a custom label, or a different ringtone for each alarm. Many users only set a one-off alarm and miss the options for weekday repetition, vibration, or automatic deletion after the alarm rings. Getting these details wrong means the alarm either fires on the wrong days or disappears after a single use when you actually wanted it daily.
Turn Camera Grid Lines On or Off
If your photos keep coming out tilted or the horizon never lines up straight, you are probably shooting without any framing guide. Xiaomi's camera app can overlay a 3x3 grid that helps you keep verticals upright and place the horizon on a clean line. Without it, minor tilts are easy to miss on a small screen and only show up later when you check the shot on a bigger display.
Edit and Rearrange Quick Settings
If the toggle you need most sits at the bottom of the control center or is missing entirely, you have to scroll or swipe further every time you want to switch it on. MIUI lets you add, remove and reorder these quick settings tiles, but the edit option is easy to miss if you have never opened it before.
Search Bar in Notification Shade
Pulling down the notification shade on a Xiaomi phone sometimes shows an extra search field at the top that you never asked for, or the opposite happens and you want that shortcut back. This toggle sits in Mi Browser, not in the notification settings where most people go looking for it. Without knowing that, the option seems to be missing entirely.
Archive a Conversation in Messages
When your chat overview gets cluttered with conversations you want to keep but do not check daily, the Messages list keeps showing all of them at the top. Archiving hides a conversation without deleting it, and you can bring it back anytime.
Delete an Alarm
If your Xiaomi phone keeps ringing at a time you no longer need, an old alarm is probably still sitting in the Clock app. Alarms pile up quickly once you set them for one-off events like flights or workouts, and they rarely get removed afterward. A cluttered alarm list also makes it harder to spot the one alarm you actually rely on every morning.
Turn Wi-Fi On or Off
If your Xiaomi phone won't connect to your home or public network, Wi-Fi might simply be switched off in the background. Leaving Wi-Fi active around the clock also drains the battery faster, especially when no network is in range. Many users struggle to find the toggle after a system update moved it inside a different menu.
Turn On/Off Traffic Mode
If a background download eats up bandwidth while you are streaming or on a video call, your Xiaomi phone might be sharing the connection equally between all apps. Traffic mode in the Wi-Fi assistant lets you decide whether the app you are actively using gets priority over background traffic. Without it enabled, downloads and updates can slow down whatever you are doing in the foreground.
Change SIM PIN
The PIN that comes preset on a new SIM card is rarely one you can memorize, and typing the wrong code repeatedly locks the card. On Xiaomi phones you can swap it for a PIN you actually remember, but the option sits a few menus deep under network security settings rather than in the main lock screen settings.
Focus & Shoot: Turn On or Off
If tapping the screen on your Xiaomi camera fires the shutter right away instead of just setting focus, Focus & shoot is switched on. Some people rely on this two-tap workflow to keep the phone steady, while others get accidental photos while they are still framing the shot.
Change Notification Sound
When every app on your Xiaomi phone plays the same generic chime, spotting an important message in a stack of notifications gets tricky. MIUI lets you pick a different tone per notification type, and if you run two SIM cards you can even split the sound by line. The tricky part is finding where this setting actually lives, since it is buried a few taps below the general Sound menu.
Restore a Local Backup
If you deleted an app or lost data on your Xiaomi phone, you don't need a full factory reset to get it back. MIUI keeps local backups separate from Google and Xiaomi Cloud backups, and picking the wrong one often leaves apps or settings missing. Knowing which backup type actually contains your data saves time before you start the restore.
Turn Best Photo Marks On or Off
If your Gallery keeps flagging one photo out of a burst as the best shot, MIUI is comparing similar images and tagging the sharpest or best-exposed one automatically. Some users find this helpful for sorting large photo batches, others just want a clean gallery without extra labels. The setting controls whether this comparison runs at all.
Set Pop-up Window Action Timeout
If a pop-up window or temporary app alert disappears before you can tap a button, or lingers on screen far longer than needed, the accessibility timeout is set too short or too long for how you use your phone. This value decides how much reaction time you get on prompts that show up briefly and then close on their own. MIUI lets you adjust this timing instead of leaving it on the default.
Schedule Dark Mode Automatically
Switching dark mode on and off every day by hand gets tedious, especially when you only want it active at night. Xiaomi phones can handle this automatically, but the scheduler sits right next to the regular dark mode switch and is easy to miss. Without setting a start and end time, the display keeps whatever theme you last picked instead of changing on its own.
Dark or Light Theme for the Phone App
If the Phone app keeps showing a bright white call screen while the rest of your Xiaomi runs in Dark mode, the dialer has its own theme setting separate from the system. This mismatch usually happens because the app theme was never linked to System default, or it got reset after an update. It affects the call screen, contact list and dial pad, not just the notification bar.
Wi-Fi Assistant: Select Best Networks Automatically
If your Xiaomi phone keeps switching away from a weak Wi-Fi network without asking, Wi-Fi assistant is likely doing that for you. Once every nearby network drops in signal, it can also fall back to mobile data on its own, which can use up your data plan faster than expected. This automatic switching can also cause interruptions during video calls or downloads.
Show Notification Content Only After Face Unlock
Sensitive notification text sometimes appears on the Xiaomi lock screen before Face unlock has actually confirmed your identity. This happens because the notification preview and the face verification step are controlled by two separate settings on MIUI. Once linked, message content only unlocks after your face data matches.
Change the Time Zone Manually
If your Xiaomi phone keeps switching its time zone whenever you travel or connect to a different carrier network, automatic time zone detection is the cause. This network-based setting overrides any manual change you make until you turn it off. Once you know where that toggle sits, you can lock in a fixed time zone yourself.
Quick Ball Shortcuts and Behavior Settings
If the floating Quick ball only opens one fixed app or keeps popping up during video playback, its behavior settings are still on default. MIUI lets you change the trigger gesture, auto-hide rules and screen position, but these options sit outside the shortcut list and get overlooked easily.
Turn Google Play Protect On or Off
If your Xiaomi keeps blocking app installs from outside the Play Store, or you get repeated malware warnings for apps you know are safe, Google Play Protect is usually behind it. The feature scans every app before and after installation and can flag legitimate apps as risky. You can check its current status and switch the scanning behavior directly from the security settings.
Turn On/Off Wi-Fi Calling
Weak signal at home, underground, or in a concrete building often causes dropped calls on a Xiaomi phone, even when Wi-Fi shows full bars. Wi-Fi calling routes voice calls through your wireless network instead of the mobile network, but only works if your carrier actually supports it. If the toggle is missing from your SIM settings, an unsupported plan or outdated carrier profile is usually the reason.
