Owners of Xiaomi and Redmi smartphones often notice a component called HMS Core in the list of running processes or in the application menu. This raises legitimate questions, especially given that the acronym HMS is associated with another large Chinese corporation - Huawei. Users are rightly afraid of hidden mining, data collection or simply unnecessary load on the system.
In fact, HMS Core (Huawei Mobile Services Core) is a basic set of system libraries that are essential for the proper operation of applications developed by Huawei. If you are not using the Huawei ecosystem, having this component on your Xiaomi Mi or Redmi may seem strange, but its presence is often due to the requirements of installed games or utilities.
In this article, we will discuss the purpose of this service, analyze the risks of its removal and explain why it may appear on devices that have nothing to do with the Huawei brand.
What is HMS Core and its Origin
HMS Core is an open-source framework that allows Huawei applications to interact with the Android operating system. Following the imposition of US sanctions, Huawei lost access to Google services (GMS), so it was forced to create its own alternative.
It’s not a coincidence that this component is happening on Xiaomi devices. Many game and application developers integrate Huawei’s SDK into their products to reach the maximum audience, including Huawei phone owners. When you install it on your Redmi Note or Xiaomi Mi, it automatically pulls up the necessary HMS Core libraries.
⚠️ Attention: Availability HMS Core on Xiaomi doesn’t mean your phone has turned into Huawei; it’s just a compatible software module running in the background to support specific apps.
Technically, it works as a bridge between the app and the system, and without it, some features may not work: you won’t be able to log in through a Huawei account, you won’t receive a push notification, or you’ll face a program crash when you launch.
💡
If you don't use Huawei apps, HMS Core is most often caused by one particular game or utility.
Why the service is installed on Xiaomi and Redmi
The question, "Why is it on my Xiaomi?" is the most popular among users, and the answer lies in the cross-platform nature of modern applications. Developers want their product to work equally well on Samsung, Xiaomi, and Huawei, so they put programs into the code depending on different service frameworks.
Often HMS Core is installed alongside popular Chinese games such as Genshin Impact, PUBG Mobile (Chinese version) or Honor of Kings. This component is also required to run some video editing applications such as CapCut or InShot if they use Huawei's cloud features.
There are several main reasons why the service appears on your device:
- 🎮 You have created a game that uses SDK Huawei to keep progress.
- 📲 You downloaded the app from a third-party store (such as AppGallery or APKPure) where the addiction was sewn in.
- 🔄 Automatic update of system components through Google Play, which tightened the compatibility libraries.
- 📦 You have installed emulators or special versions of applications that require a Huawei runtime environment.
It’s important to understand that HMS Core is not a virus in itself; it’s a legitimate system component certified to run on Android, but its background activity may be a question for smartphone owners with little RAM.
Impact on battery and performance
One of the main fears of users is battery life: because HMS Core is a background service, it can consume the resources of the processor and the power system. On modern Xiaomi models with Snapdragon or MediaTek processors, the impact of one additional service is minimal and almost invisible in everyday use.
This changes if the service is not working properly, for example, if an application that requires HMS is constantly trying to sync data, but the connection to the server is unstable, a so-called "wakelock" can occur, in which case the phone does not go into deep sleep, and the battery runs out faster.
To check the impact of the service on your device, follow the following steps:
- Go to Settings → Battery and Performance.
- Click on the gear icon or go to the expense statistics.
- Find HMS Core or com.huawei.android.hms.agent.
- Estimate the percentage of consumption: if it is less than 1-2%, there is nothing to worry about.
⚠️ Attention: If HMS Core consumes more than 10% of battery life per day, which is a sign of a failure, in which case it is recommended to clear the application cache or reinstall the software that depends on it.
The service has little impact on gaming performance unless it conflicts with other system processes. In most cases, Xiaomi MIUI or HyperOS successfully manage background tasks, freezing unnecessary processes.
Can I remove HMS Core on Xiaomi?
Technically, it is possible to remove HMS Core, but you need to be aware of the consequences. It is not an Android system file needed to boot the phone, so deleting it will not lead to a brick or a bootloop.
If you remove this component, games will stop saving progress in the Huawei cloud, notifications will stop coming, and some programs will simply stop running, giving an error at start.For the average user who is not using the Huawei ecosystem, deletion often goes unnoticed, but the risk of failure of the favorite game remains.
Let’s look at the options in the table:
| Action. | Effects of consequences | Recommendation |
|---|---|---|
| Leave it as it is. | Stable operation of all applications, minimum battery consumption. | ✅ The best option for most. |
| Stop forcefully | The service will restart when the dependent application is launched. | ⛔ Temporarily, no point. |
| Remove via ADB | Huawei apps will stop working, errors are possible. | ⚠️ Only for experienced users. |
| Turn off in the settings | Similar to removal, but easier to restore. | ✅ An acceptable compromise. |
It is worth noting that complete removal often requires superuser rights (Root) or the use of a USB debugging computer. Simply removing the icon from the desktop does not uninstall the service itself.
💡
Removing HMS Core is safe for Android, but it can break the functionality of the specific games and apps you use.
Instructions for disabling and managing the service
If you’ve decided you don’t need Huawei services on your Xiaomi Mi, you can try to limit their activity to regular system tools, which is safer than completely removing them, and allows you to quickly return everything back in case of problems.
First, you need to find the app itself in the settings, which can be called HMS Core, Huawei Mobile Services, or hidden under the name of the package com.huawei.android.hms.agent.
Follow the following steps to limit background activity:
- 📱 Open the Settings. → Annexes → All applications.
- 🔍 Find it on the list. HMS Core (use search).
- 🛑 Press the Stop button (if active).
- 🔋 Select Energy Saving and set No Limits (to control manually) or Limit background activity.
- 🚫 Press Permissions and disable geolocation, microphone and contacts.
A more radical method is the use of ADB (Android Debug Bridge), which requires connecting a smartphone to a computer.
adb shell pm uninstall -k --user 0 com.huawei.android.hms.agentThis command will delete the packet for the current user without affecting the system partition. To return it all back, you just need to reset the application settings or use the cmd package install-existing command.
☑️ Safe shutdown HMS

Data security and confidentiality
HMS Core, like Google Play Services, has broad access rights; in theory, it can collect telemetry, location data and a list of installed applications; Huawei’s privacy policy states that data is used to improve services and targeted advertising.
For Xiaomi users, this creates a “double agent” situation: your data can potentially be processed by two large corporations. However, unless you are a Huawei ID, the amount of personal information collected is minimal.
The main aspects of safety:
- 🔒 Encryption: Data is transmitted over secure protocols.
- 👁️ Transparency: You can see what permissions are requested in the settings menu.
- 🌐 Servers: Data may be processed on servers in China or Europe, depending on the region of the account.
⚠️ Note: If you are concerned about privacy, do not link your main Huawei account to apps on Xiaomi.Use guest mode or do not sign in to Huawei profile at all unless urgently needed.
Antivirus scanners built into MIUI or installed separately (Dr.Web, Kaspersky) typically label HMS Core as safe, but can sometimes react to its activity as “Riskware” (potentially unwanted software) due to aggressive telemetry collection.
