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.
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.
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.
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.
Enable Keyboard Dark Theme in Battery Saver
If your Xiaomi keyboard stays bright white even after battery saver kicks in, the automatic dark theme switch for the keyboard is turned off. This setting is separate from the general dark mode toggle and only reacts to the power-saving state of the phone. Without it, the keyboard ignores battery saver and keeps burning extra power on OLED screens.
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.
Turn Do Not Disturb On or Off
When Do Not Disturb is active on your Xiaomi phone, calls get an instant busy signal and every notification stays silent, even for messages you actually want to hear. Many people leave it on by accident after enabling it for a meeting or at night, since MIUI does not always show a clear reminder that it is still running. Checking the current status and switching it off takes just a few taps in Sound & vibration settings.
Set Up a Proxy Server for Wi-Fi
If your network admin or workplace requires traffic to run through a specific server, a plain Wi-Fi connection on your Xiaomi phone will not route it correctly. Without a configured proxy hostname and port, apps either fail to connect or bypass the required server entirely. This affects browsing, app updates and anything that depends on that network policy.
Clear the Whole Call History
When missed, dialed, and received calls pile up on your Xiaomi phone, scrolling through the list to find one number gets tedious fast. Deleting entries one at a time barely makes a dent if you actually want a clean call log. MIUI offers a single action that wipes the entire history at once, and once it's gone, it's gone for good.
Filter Contacts by Account
If your contact list mixes phone numbers, WhatsApp entries, and other synced accounts, finding the right person gets messy fast. MIUI keeps every synced account in one long list by default, which makes Calls and Messages harder to scan. A built-in filter lets you narrow that view down to only the account you actually need.
Turn Bluetooth On or Off
If a Bluetooth headset, speaker, or car kit will not pair with your Xiaomi phone, Bluetooth is often still switched off or was never fully enabled after a restart. The Quick Settings toggle can also drift out of sync with the actual radio state, which leaves paired devices unable to reconnect until you check the setting directly.
Change SIM Card Name
Two SIM cards from the same carrier look identical on your Xiaomi phone, so it is easy to grab the wrong one for a call or a mobile data session. MIUI shows a generic carrier label for each slot by default, which does not tell you which SIM is your personal number and which one is for work or travel. Giving each SIM card its own name in the phone settings clears up that confusion for good.
Turn Dual Clock On/Off on Lock Screen
After switching the region on a Xiaomi phone, a second time suddenly shows up on the lock screen next to the main clock. This happens because MIUI detects a time difference between your set region and your current location or SIM, and the Dual clock feature reacts automatically. You can switch it off entirely or change which region the second clock refers to.
Vibration in Silent Mode: Turn On or Off
When you switch a Xiaomi phone to Silent, it still buzzes for every incoming call or message by default. If you want the device completely quiet without any buzzing on the table, you need a separate toggle beyond the ringer switch itself.
Turn Data Roaming On or Off
If your Xiaomi phone connects to a foreign network, no data moves until data roaming is switched on. Once active, you get internet access abroad, but your carrier may bill extra for it. Xiaomi does not offer a simple on/off toggle here - it gives you three distinct roaming states, and picking the wrong one either blocks data or leaves roaming running when you do not want it.
Change Time Format
If your Xiaomi phone shows time in a format you did not choose, MIUI is likely following your system language setting automatically. This means the clock can jump between 12-hour and 24-hour display whenever you change language or region. You can lock the format manually so it stays consistent no matter what language MIUI is set to.
Add or Remove Bookmarks in Mi Browser
Losing track of a website you visited last week is common once it drops out of your browser history. Bookmarks fix this by saving the page permanently until you decide to remove it. The catch is that many Xiaomi users don't know where the bookmark list actually lives inside Mi Browser, so saved pages get forgotten or accidentally deleted.
Disable Automatic Video and Image Downloads in Mi Browser
If your mobile data disappears fast while browsing on your Xiaomi phone, Mi Browser might be pre-loading videos and images before you even tap them. This automatic download feature speeds up page loading but quietly eats into your data plan. Turning it off puts you back in control of what actually gets downloaded.
Create a Folder on the Home Screen
If your home screen is cluttered with dozens of app icons, grouping them into folders keeps things organized. On MIUI, folders are created by dragging one app icon onto another, the same drag-and-drop gesture you might know from a PC desktop or other Android phones. You need at least two apps ready to combine before a folder actually appears.
