Turn On Second Space
If you want to keep work apps, private photos, or a guest profile completely separate from your main Xiaomi setup, mixing everything into one home screen becomes a mess fast. Second space creates an isolated area with its own apps, files, and accounts, so nothing from one side leaks into the other. It is different from a simple app lock, because the whole environment is duplicated rather than just hidden.
Set Up an App Timer
If an app on your Xiaomi phone keeps eating hours of your day without you noticing, MIUI does not limit it automatically. Digital Wellbeing only tracks usage in the background unless you configure a timer yourself for that app. Without that timer, games or social media apps stay open all day, no matter how long you actually meant to use them.
Set Autoclick Dwell Timing for a Mouse
If you control your Xiaomi phone with a connected mouse, clicking a tiny cursor button gets tiring fast. Autoclick (dwell timing) lets the phone register a click automatically once the pointer stops moving for a set time. The delay is adjustable, so a short dwell time can trigger accidental taps while a long one feels sluggish.
Save Photos and Videos to SD Card Automatically
If your Xiaomi phone keeps filling up internal storage even though a microSD card is inserted, the camera is probably still saving everything to the phone by default. New shots and clips pile up locally instead of moving to the card, which quickly triggers low-storage warnings.
Reset Camera Settings to Default
If your Xiaomi camera keeps producing blurry shots, odd colors, or a shooting mode you no longer understand after trying out filters and manual adjustments, restoring the default configuration usually fixes it. This clears every custom change you made in the camera app without touching photos or videos already saved on your phone. It is the fastest way to undo settings that got out of control after too much tinkering with exposure, resolution, or scene modes.
Add a Print Service
If a print dialog on your Xiaomi phone shows no printer at all, no print service is registered in MIUI yet. Most phones only come with a driver for Epson devices, so printers from other brands stay invisible until you install their own service. Without that step, apps like a PDF viewer or browser can never send a job to your printer.
Turn Data Usage On or Off for a SIM Card
If mobile data suddenly refuses to turn back on after your phone hit its limit, the culprit is usually the Data usage toggle inside the Security app. Xiaomi switches off the connection automatically once the set threshold is reached, and it stays off until you flip that switch again. The same setting also lets you disable mobile data manually before any limit is close.
Turn On/Off Ultra Battery Saver
When your Xiaomi phone drops to critical battery, apps stop refreshing in the background and the screen switches to a dark theme without asking first. That is Ultra battery saver taking over, and it can feel like half your phone stopped working until you know how to control it.
Turn Off Automatic Diagnostic Data Sending
If Send diagnostic data automatically stays enabled, your Xiaomi phone keeps transmitting usage statistics that can include personal details. Many people only notice this after checking a privacy report or reviewing background data usage. MIUI never discloses exactly what content gets sent in these reports, which is why disabling related user experience options is worth doing.
Change Ringtone for Event Reminders
If every calendar reminder, note alert, and task notification on your Xiaomi phone plays the same generic tone, it's easy to miss what actually matters. Event reminders use a separate sound slot from calls and messages, so changing your default notification tone alone does nothing. MIUI lets you assign a dedicated tone just for these reminders, from either Xiaomi's included tones or your own sound files.
Turn Emergency Location Service (ELS) On or Off
If first responders cannot pinpoint your position during an emergency call or text, Emergency Location Service on your Xiaomi phone may be switched off. This feature sends your current GPS position automatically whenever you dial an emergency number, but it only works if the setting is active and your wireless carrier supports it. Some users disable it by accident while adjusting location permissions, which delays help in a real emergency.
Set Up a Privacy Protection Password
Anyone who unlocks your Xiaomi phone can still open apps like Gallery, Notes, or File Manager without a second check, exposing personal photos or documents. The screen lock protects the whole device but not individual apps, which is where a separate privacy password comes in.
Clear Cache (Storage & Backup)
If your Xiaomi phone feels slower than it used to, or apps freeze and crash for no clear reason, piled-up cache files are often the cause. MIUI stores thumbnails, temporary downloads and leftover app data that nobody ever cleans up manually. Over time this clutter eats into your free storage and can trigger odd system errors that have nothing to do with the apps themselves.
Blur Effect for App Previews
When you swipe through recent apps on your Xiaomi phone, the preview thumbnails can show account balances, chat messages or other personal details in plain sight. MIUI lets you blur individual app previews so text and layout become unreadable at a glance. The setting works per app, which means it is easy to forget for apps you add later, such as a new banking or messaging app.
Schedule Always-on Display
If the Always-on display on your Xiaomi phone stays lit all day or switches off at the wrong hours, MIUI is likely running a fixed on/off pattern instead of your own schedule. You can define exact start and end times for the display elements yourself. You can also decide whether the Always-on display keeps working once Battery saver kicks in.
Adjust Screen Brightness
If the display on your Xiaomi phone looks too dark indoors or blinds you at night, the brightness slider is set wrong or auto-brightness is fighting your manual changes. A screen running at full brightness all day is also one of the fastest ways to drain the battery. Getting the level right matters both for comfort and battery life.
Set a Button Shortcut for Split Screen
Opening split screen through the recent apps menu takes several taps and only works if you can find the small split-screen icon on the app card. If your phone uses button navigation instead of gestures, there is a faster way: a long press on one of the navigation buttons can trigger split screen directly.
Add Contacts to a Group
Groups on your Xiaomi phone stay empty until you actually assign contacts to them. You can add people either from a single contact's profile or from inside the group itself, and mixing up the two methods is where most confusion starts. Knowing which screen controls group membership saves you from re-adding the same contact twice.
Rename Face Data
If you have saved more than one face profile on your Xiaomi phone, for example a regular look and one with glasses, every entry shows up under the same generic label in the Face unlock settings. Without a custom name it is hard to tell which profile matches which appearance, especially when you only want to manage or delete one of them.
Manage Synced Gallery Albums
When Xiaomi Cloud sync is turned on, Gallery uploads every new photo and video automatically, including albums you would rather keep local. That fills up your cloud storage fast and makes it hard to tell which albums are actually being backed up. Instead of switching cloud backup off completely, you can review and adjust the sync status for each album on its own.
Delete a Conversation
Deleting a text thread one message at a time on a Xiaomi phone takes forever once a conversation has piled up over months. Long threads eat into storage and clutter your inbox, and most people never notice the shortcut MIUI offers for removing a whole conversation at once. Once you confirm the deletion, the messages are gone for good, so it helps to know exactly where to tap first.
Send a Group Message (SMS/MMS)
When you try to text several people at once on a Xiaomi phone, it is not always clear whether picking multiple names in Contacts actually creates a real group thread. MIUI also switches silently between SMS and MMS depending on whether photos or long text are attached, so replies can end up scattered across separate one-on-one chats instead of a single conversation.
Turn MMS Read Receipts On or Off
If contacts can see the moment they read your MMS messages, or you cannot tell whether your own texts got opened, the read receipt option is likely misconfigured on your Xiaomi phone. This setting works separately from standard SMS delivery reports and needs its own toggle inside the messaging app. On Dual SIM devices, each SIM line can carry a different receipt setting, which often explains why the behavior seems inconsistent between conversations.
Turn On/Off Ascending Alarm Volume
If your Xiaomi alarm starts at full volume and jolts you awake instead of easing you into the morning, the ascending volume option is likely switched off. Some users prefer the opposite: a gentle ramp-up feels too quiet to wake them at all. Either way, this sits in a separate alarm setting that many people never notice.
