Modern Xiaomi smartphones, which are based on the MIUI shell or the new HyperOS, have a powerful power optimization system, which often perceives instant messengers as background processes that can be safely closed to save charge, which is why many users face a situation where WhatsApp messages arrive with a delay or do not appear at all before the application opens.
Proper initial setup is critical to the stable operation of the messenger. If you ignore the system permissions and battery settings, you risk missing important calls or work chats. In this guide, we will examine not only the basic installation, but also the deep system settings that will ensure instant delivery of messages.
The configuration process takes only a few minutes, but requires attention to the details of the interface. We will look at both standard installation steps and Xiaomi-specific features, such as app cloning and auto-run control, which will allow you to use the messenger as efficiently as possible.
Installation and initial activation of the account
The first step is to download the app distribution. Xiaomi devices use the GetApps store by default, but to ensure that you get the latest version with the latest security patches, you should use the official Google Play Market. Find the application on "WhatsApp Messenger" and click "Install".
Once you've downloaded it, it'll appear on your desktop. Android will ask for basic permissions when you first start up. A contact book, microphone, and camera are the minimum set you need to make your messenger work properly. Without access to your contacts, you won't see your names, just your phone numbers.
The process of verifying the phone number is standard: you enter your number, you get it. SMS-It is important to ensure that the device is stable mobile network or Wi-Fi at the time of the request. After successful code entry, the system will prompt you to restore a backup from Google Drive if it was previously created.
⚠️ Note: Never provide a confirmation code from SMS WhatsApp or police never ask for this code, which is the most common method of stealing accounts.

Optimization of battery operation and background
This is the most important section for Xiaomi owners: An aggressive power saving system can kill the messenger process, which prevents notifications from coming. To avoid this, you need to manually add the application to exceptions. Go to Settings → Apps → All apps and find WhatsApp list.
In the app menu, select Charge Savings. The default mode may be "Energy Savings." You need to switch it to "No Limits." This action will allow the system to use the necessary CPU resources to maintain a constant connection to the server, even if the screen is off.
Then you should set up autorun. In the same menu of the app settings, find the Autorun switch and activate it. This ensures that after the smartphone restarts, the messenger will start automatically and will be ready to receive incoming calls and messages without your intervention.
Why is MIUI killing apps?
It’s also worth checking for updates to the app itself through the Play Market.Developers regularly release patches that improve compatibility with different versions of Android and manufacturers’ shells.The outdated version may not work stable on Xiaomi’s new firmware.
Set up notifications and sound accompaniment
The notification interface in MIUI has its own features. To ensure that messages are displayed correctly, go to Settings → Notifications inside the app menu. Here you can customize the behavior of notifications in detail: allow them to be displayed on the lock screen, in the curtain and as floating windows.
To adjust the sounds, you need to go directly to the settings inside WhatsApp itself. Open the app, click on the three dots in the upper right corner, and select Settings → Notifications. Here you can set individual tones for messages, group chats, and incoming calls.
- 🔔 Notification Sound: Select the melody that will play when the new message is sent.
- 📳 Vibrosignal: You can adjust the vibration pattern or turn it off completely.
- 🌙 Night mode: allows you to turn off sounds and vibrations at a given time, so as not to wake up the household.
It’s important to note that if you have Do Not Disturb mode enabled on Xiaomi’s system, it will prioritize the messaging settings. Check the schedule of this mode in the phone’s general settings to make sure it doesn’t block calls from important contacts at the wrong time.
Use of the application cloning function
One of the most useful functions of the shell MIUI It's called app cloning, and it allows you to run two independent WhatsApp accounts on one device, and it's perfect for people who use one. SIM-card for work and another for personal use but doesn't want to carry two phones.
To activate this feature, go to Settings → Apps → App Cloning. In the list, find WhatsApp and activate the switch. The system will create a copy of the application with a small icon-marker. When you launch the cloned version, you will be able to register a second phone number.
Both apps work independently, they can have different notification settings, different avatars, and different accounts, but remember that both instances consume RAM and battery power, since they are actually two running processes.
⚠️ Note: For the second account in the phone must be installed second SIM-card or an alternative method of reception SMS to confirm the number (for example, via another phone).
The cloned app also requires a separate set of access rights and battery savings, as described in the previous sections.Be sure to check the settings for both icons so that notifications arrive stably on both numbers.
Memory and media management
WhatsApp has the ability to store a huge amount of data. Photos, videos and voice messages are stored in the device’s memory, taking up gigabytes of space, which over time can lead to slowdown of the Xiaomi smartphone and lack of space for new files.
To manage storage, use the built-in cleaning tool. Inside the app, go to Settings → Data and Storage → Storage Management. Here you will see a list of chats sorted by volume, and you can delete heavy files or entire correspondence.
It is also recommended to disable auto-save media files in the phone gallery, so as not to clog the main MIUI tape. In the settings of the messenger in the Chats section, turn off Media Visibility. Photos will remain available inside correspondence, but will no longer be displayed in the general gallery of the smartphone.
| Type of data | Where it takes place | Cleaning recommendation |
|---|---|---|
| Photos | WhatsApp/Media folder | Delete through storage management |
| Video | Take up the most space. | Set up auto download only over Wi-Fi |
| Voice-over. | Little space, but lots of files. | Cleaning up old chat rooms completely |
| Documents | Different formats | Move it to the cloud or PC |

Regularly cleaning cache and media files through the built-in WhatsApp menu prolongs the life of the smartphone drive and speeds up its work.
Configuring privacy and security
Security is a priority for most users. WhatsApp has end-to-end encryption enabled by default, but additional privacy settings require your attention. Go to Settings → Privacy.
Here you can hide the time of your last visit, the status of "A" and information about reading messages (blue ticks). For increased security, it is recommended to enable two-step authentication. PIN-When you try to register your number on a new device.
