If you've ever looked at the installed app list on a Xiaomi smartphone, you've probably noticed the mysterious name Device Health Services, which doesn't have a desktop shortcut, doesn't appear on the settings menu, but it takes up space in memory and sometimes consumes CPU resources. What is it? Why is it needed? Can it be removed without system consequences? In this article, we'll go into detail all aspects of Device Health Services, its relationship to device performance, and give clear guidelines for managing this service.

Many users mistake Device Health Services for a virus or an unnecessary software, especially when they see it on the list of active processes. MIUI, It is integrated into the system for mission-critical functions, and its role is often underestimated, although the stability, safety and even battery life of your smartphone depends on the correct operation of this service. Next, we’ll explain why it’s not just a “background app,” but one of the key elements of Xiaomi’s architecture.

What is Device Health Services on Xiaomi and Why You Need It

Device Health Services (translated as “Device Status Services”) is a system component of firmware. MIUI, It's a service that monitors the hardware and software health of a smartphone, and unlike consumer apps, it works at a low level of the system and interacts directly with the Android kernel and Xiaomi proprietary drivers:

• 🔋 Battery condition control: tracking charging cycles, temperature, wear and avoidance of critical situations (e.g. overheating or deep discharge).
• 🛠️ Diagnostics of hardware components: checking the operability of sensors, communication modules (Wi-Fi, Bluetooth, NFC) and RAM.
• 🔒 Protection against malware: participation in security mechanisms MIUI, including scanning system files for changes.
• 📊 Performance optimization: collecting statistics on processor load, RAM usage, and offering solutions to speed up work.

Device Health Services is not a standalone application, but part of a larger ecosystem. MIUI. It is closely linked to other system services such as com.miui.securitycenter and com.miui.powerkeeper. For example, when you see a notification of high battery consumption by an app, this information comes from Device Health Services, which analyzes data from the power controller.

Starting with the version MIUI 12, this service is also responsible for the “Smart Optimization” function, which automatically closes the background processes, clears the cache and redistributes resources depending on the use case (games, video viewing, normal mode). Without it, many power-saving features like Ultra Battery Saver or Adaptive Battery simply won’t work.

How Device Health Services Affects Performance and Battery

One of the most common questions users ask is, "Why is Device Health Services loading the CPU and burning the battery?" Indeed, in some cases, this service can consume up to 5-15% of the charge per day and periodically activate the CPU cores. However, this is not always a sign of malfunction.

• 🔄 After updating MIUI: The service conducts a full diagnostic of the system, which can take several hours and be accompanied by increased resource consumption.
• 🔋 When charging: Device Health Services analyzes battery parameters (temperature, current, voltage) and adjusts charging algorithms to extend life.
• 🚨 If problems are detected: if the service detects problems (for example, overheating or sensor failures), it can increase the frequency of checks, which affects autonomy.

Normally, Device Health Services should not consume more than 1 to 3 percent of its battery per day, and if you see values above 10 percent, it could indicate:

1. Failures in the firmware (for example, after an incorrect update).
2. Conflict with other system services or third-party applications (especially with “optimizers” or antiviruses).
3. Hardware problems (for example, a faulty battery or overheating of the processor).

To check the impact of the service on autonomy, go to Settings → Battery → Battery usage and find Device Health Services on the list.If consumption is above normal, try restarting the device or resetting the battery settings via Settings → Battery → ⚙️ → Reset battery statistics.

💡

If Device Health Services consumes more than 20% of the battery, try calibrating the battery: completely drain the phone before turning it off, then charge to 100% without interruption.

Can Device Health Services be removed and what will it lead to?

Device Health Services can be technically removed, but it is strongly discouraged unless you are prepared to face serious consequences. MIUI, and its removal will lead to:

If you want to get rid of Device Health Services, the only relatively safe way to do this is to turn off individual functions through the developer settings or Magisk modules, for example, you can deactivate statistics collection or battery status notifications, but still keep the service kernel running.

⚠️ Note: Device Health Services may be removed or modified to result in the loss of warranty on the device, which the manufacturer considers to be an interference with system software, which is a violation of the terms of service.

How to Disable or Limit Device Health Services Without Harming Your System

If the service is disruptive, but you don't want to risk the stability of your smartphone, you can compromise by limiting its activity.

Disable the collection of diagnostic data|Limit background activity through battery settings|Use Magisk modules to partially shut down|Reset service settings to factory-->

1. Disabling the collection of diagnostics

Go to Settings. → The phone. → All parameters. → Send an error report and disable Automatic Reporting, which will reduce service activity but will not affect critical functions.

Limitation of background activity

Settings menu → Battery → Find Device Health Services and set it to Restricted mode.This will reduce resource consumption, but may cause delays in notifications of battery problems.

3. Use of Magisk modules

For advanced users, a module is suitable Disable_MIUI_Battery_Monitor (It only disables battery monitoring, leaving the rest of the service intact. It can be installed via Magisk Manager:

1. Download the module in.zip format


2. Open Magisk → Modules → Install from storage




3. Select the file and confirm the installation




4.Reset the device

4. Resetting service settings

If Device Health Services is behaving inappropriately (e.g., constantly showing sensor errors), reset its settings via Settings. → Annexes → Application management → ⚙️ → Reset the application settings. This will bring the service back to factory status without deleting it.

💡

Even after deactivating some of the functions, Device Health Services continues to work in the background, providing basic protection for the system.

Device Health Services and Security: Does Xiaomi Collect Your Data?

Many users worry that Device Health Services may be transferring personal data to Xiaomi, so let’s look at what it collects and where it sends it.

According to Xiaomi, Device Health Services collects the following types of data:

• 📱 Technical parameters of the device: model, firmware version, serial number (but not IMEI).
• 🔋 Battery data: number of charging cycles, temperature, wear level.
• 🚀 Performance statistics: processor load, RAM usage, application failures.
• 🔌 Connection information: stability of Wi-Fi, Bluetooth, mobile network (no password transfers or connection history).

It is important to note that:

1. The data is anonymized before being sent to Xiaomi servers.
2. The information is used only to improve the firmware and is not sold to third parties (this is stated in the company’s privacy policy).
3. You can turn off the diagnostic collection at any time (as described in the previous section).

However, if you're concerned about data transfer, you can block Device Health Services' access to the Internet entirely through a firewall.

1. Install the NetGuard or AFWall app+ (Root rights are required).
2. Find the Device Health Services package (com.miui.health or com.miui.batterymanager).
3. Block access to the mobile network and Wi-Fi.

⚠️ Attention: Blocking network access may result in the service being unable to download database updates to diagnose hardware components, resulting in some features (e.g. battery authentication) not working properly.

Device Health Services on different versions MIUI: changed

Device Health Services functionality has evolved with firmware MIUI. Let’s look at the key changes in different versions:

Starting with MIUI 12.5, Device Health Services has become more “smart”: it analyzes user habits and adjusts optimization algorithms to suit individual scenarios. For example, if you play heavy games often, the service will be more active in cooling the processor, but at the same time limit the background activity of other applications.

The HyperOS (which has replaced the MIUI On new devices, this service has additional functions:

• 🤖 AI Battery Wear Prediction: Based on your charging habits, the service predicts when battery replacement will be needed.
• 🌡️ Adaptive cooling: dynamically adjusts performance based on ambient temperature.
• 🔄 Automatic Recovery: If the service detects sensor failures, it tries to reboot them without user intervention.

If you’re using a HyperOS device, it’s not recommended to disable Device Health Services — this could cause new features like Xiaomi Smart Hub or Cross-Device Connectivity to malfunction.
