The problem is familiar to millions of users — especially owners of Redmi, POCO and Mi series smartphones. In 2026, the number of complaints about malfunctions in the messenger increased by 40% compared to last year, and the fault is not only the updates of the application itself, but also the features of the MIUI firmware.

In this article, we will not just list the standard tips like "reinstall the app" or "check the Internet." We will examine the hidden reasons associated with optimizing energy consumption in the Internet. MIUI, conflicts with Google's system services, and rare bugs that are not even mentioned in official support, such as did you know that some Xiaomi models are not available for use in the company? 12T And Redmi Note 11 WhatsApp is blocked due to a malfunction of com.google.android.gms? → Performance mode can completely "kill" the background activity of the messenger?

If you've tried the obvious solutions before and they haven't worked, this is the guide for you. We've gathered data from the 4PDA forums, XDA Developers, and user feedback to identify unique WhatsApp crash patterns on Xiaomi devices, and at the end of this article, you'll find a checklist to quickly diagnose the problem.

Battery Optimization in MIUI: Why WhatsApp is Falling Asleep

The most common reason WhatsApp doesn’t work on Xiaomi is the aggressive power optimization in MIUI. The system automatically restricts the background activity of applications to extend battery life, but often does so too zealously, as a result of which the messenger stops receiving notifications, does not update chats and may not open at all.

This is especially true for Snapdragon processors. 4xx/6xx (Like Redmi. 9A, POCO M3), where MIUI The default mode is Adaptive Battery, but WhatsApp's settings may allow auto-start and background activity, but the system still blocks it through the app. 10–15 minutes of inactivity.

• 🔋 Ultra-low mode: activates at a charge level below 15% and completely disables background processes.
• ⚡ Optimization MIUI: Even if you manually allow WhatsApp to work in the background, the system can reset settings after the update.
• 📱 Specifics of processors: on MediaTek Helio G (for example, Redmi Note 10) optimization is more rigid than on Snapdragon.

Symptoms: the application opens but can not connect to servers, constantly requests a phone number check or issues an error "WhatsApp can not connect to the Internet" - despite a stable connection.

The reason lies in the conflict between com.google.android.gms and MIUI system libraries. Xiaomi uses its own modified versions of some Google services, and after updating them, authentication may fail, most often affecting devices on MIUI 13/14 with unstable beta versions of the firmware.

• 📱 Try accessing WhatsApp from another device (such as a tablet or PC via the web version).
