Where in Xiaomi hidden energy saving policy: a full analysis of settings for smartphones and smart technology

When it comes to power saving in Xiaomi devices, many users are faced with a paradox: on the one hand, the manufacturer is actively promoting “smart” power management algorithms, and on the other hand, these settings are scattered on different menus, and sometimes completely hidden from view. This topic is especially relevant for owners of smartphones of the Redmi, POCO and Xiaomi 12/13/14 series, where aggressive optimization of background processes can conflict with the user experience (for example, when applications suddenly “fall asleep” or notifications come with a delay).

In this article, we will not only list where to find energy saving policies in MIUI 12/13/14 and HyperOS firmware, but also understand:

• 🔍 How different settings for smartphones, smart watches (Mi) Band/Watch) routers
• ⚡ What hidden options affect real-time work (and why they are not visible in the standard menu)
• ⚠️ When energy saving is harmful – cases when it is better to turn it off

Important: In Xiaomi devices from 2023, the energy saving policy is divided into three levels – system (firmware), hardware (chipset) and cloud (Xiaomi Cloud services), and each of them requires a separate setup.

1. Where to look for power saving settings in MIUI and HyperOS

Depending on the firmware version, the path to the power-saving menu may differ: in MIUI 14 and later (HyperOS), developers have made access easier, but left the "old" ways for compatibility.

• 📱 Smartphones Xiaomi/Redmi/POCO: Settings → Battery and productivity → Battery mode Settings → Additionally. → Special facilities → Battery Optimization (Hidden Section)
• ⌚ Smartwatches (Mi Band) 7/8, Watch S3): In the Mi Fitness app: Device profile → Settings → Energy saving on the watch itself: settings → Display and brightness → Sleep regimen
• 📡 Routers (Xiaomi Router) 4A/AX3600): Web interface: Additional settings → Power Management Mobile application Mi WiFi: Device → Energy consumption

On smartphones with HyperOS (such as Xiaomi 14 or Redmi K70), a new section called Intelligent Management has been introduced, where the system itself suggests optimizing battery consumption based on the user’s habits, but this algorithm is often wrong – for example, it can limit the background activity of messengers during working hours.

⚠️ Note: On some models (e.g, POCO F5) Battery optimization is hidden. To open it, you need to search for settings to query "energy saving policy" or use hidden code.

2. Hidden settings: how to enable the extended mode of energy saving

By default. MIUI It offers three standard modes: Balanced, Energy Saving and Super Energy Saving, but there's another one in the firmware, Ultra Battery Saver, which is activated only through an engineering menu or a power-saving system. ADB-This mode disables all background processes except calls and SMS, It can extend the smartphone to 5-7 Days (tested on Redmi Note) 12 Pro+).

To turn it on:

1. Activate Developer Mode (7 times click on the MIUI version in Settings → About Phone).
2. Return to Settings → Additional → For developers and enable USB debugging.
3. Connect your smartphone to your PC and execute the command: adb shell settings put global ultra_power_mode 1
4. Reboot the device. The new mode will appear in Settings → Battery.

It shuts down similarly, but with a 0 instead of a 1. Warning: push notifications, geolocation and most widgets do not work in this mode.

3. Energy saving in smart watches Xiaomi: features of the Mi Band and Watch

Unlike smartphones, where energy saving policies are flexible, Xiaomi smartwatches are tightly bound to hardware constraints, such as the Mi Band 8 power saving mode turns off:

• 📊 Constant monitoring of heart rate (measured only when manually requested)
• 🌙 Automatic sleep phase detection (manual activation required)
• 📱 Notifications from third-party apps (only calls remain)
• 🔋 Illumination of the screen when lifting the hand (works only on the button)

Interestingly, the Xiaomi Watch S3 added an adaptive mode that analyzes the user’s activity level and automatically switches between normal and energy-saving modes. However, this algorithm only works when synchronized with the Mi Fitness app at least 1 time every 12 hours.

⚠️ Note: In Xiaomi watches, there is no option to selectively turn off energy saving for individual functions (for example, leave heart rate, but turn off). GPS). The system works on the principle of “all or nothing».

4. Xiaomi Routers: The Power Saving No One Is Talking About

Few people know, but Xiaomi routers (for example, AX3600 or Router 4A Gigabit) also have power saving settings - they affect power consumption and the stability of the Wi-Fi network. By default, the router operates in High Performance mode, which consumes up to 12 watts, but at night you can switch to Eco mode (consumption ~ 5 watts).

Where to set it up:

1. Open the router's web interface at 192.168.31.1.
2. Go to Additional Settings → System Tools → Power Management.
3. Select a Schedule and specify the hours when the router should switch to eco-mode (for example, from 23:00 to 7:00).

What is changing in the eco-regime:

• 📶 Wi-Fi power is reduced by 30% (radius is reduced)
• ⚡ One of the antennas is turned off (in dual-band models)
• ⏱ Package processing is slowed down (ping increases by more) 10-15 miss)

Important: If you have smart devices connected (like Xiaomi Home cameras), they may lose connection to the router in eco mode.

5 When energy saving is harmful: 5 times it needs to be turned off

Aggressive energy saving policies in MIUI can lead to unexpected problems, and here are the best situations to deactivate them:

1. Navigation applications (Google Maps, Yandex.Navigator): In power saving mode, GPS can be turned off after 10-15 minutes of inactivity of the screen, which leads to loss of route.
2. Background video recording (e.g. in DashCam mode): The camera can stop recording if the smartphone is locked.
3. Cloud-saving games (Genshin Impact, Honkai: Star Rail): Background data synchronization may be interrupted, resulting in loss of progress.
4. Working with external devices (OTG-accumulator, MIDI-keyboard): USB-The port can be shut down after 5 minutes of inactivity.
5. Remote management (via TeamViewer or AnyDesk): A session may be disrupted due to limited background processes.

To temporarily turn off energy saving for a particular application:

1. Go to Settings → Applications → Application Management.
2. Select the application you want (such as Google Maps).
3. Press the Battery. → No restrictions.

Exception: On some models (e.g. Xiaomi 13 Ultra), even after the restrictions are turned off, the system can force the application to “sleep” after 30 minutes, in which case only manual change of parameters through ADB will help.

💡

If the GPS still shuts down after the power saving is turned off, check the Location Optimization settings in Settings → Location → Accuracy Mode. Select High Accuracy and turn off the Location Saving option.

6.Cloud Energy Saving: How Xiaomi Cloud Manages Your Battery

Since 2022, Xiaomi has implemented a cloud-based battery optimization mechanism that analyzes user habits and remotely adjusts energy saving settings. For example, if you normally charge your smartphone at night, the system can automatically activate Super Power Saving mode after 23:00.

The problem is that this mechanism doesn't always work correctly, and Redmi Note 11 Pro+ users complained that after upgrading to MIUI 14, the smartphone spontaneously switched to power saving mode during the day, blocking notifications from working messengers.

1. Open Settings → Accounts → Xiaomi Cloud
2. Go to Synchronization and Backup → Device Optimization.
3. Turn off the Adaptive Energy Saving Slider.

If this option is not available in your MIUI version, your device does not support cloud optimization (relevant for models older than 2021).

⚠️ Warning: Disabling cloud energy saving can lead to increased battery consumption 10-15%, But it will take back control of notifications and background processes.

💡

Cloud-based battery optimization only works when synced actively with Xiaomi Cloud. If you’re not using the cloud, that mechanism automatically shuts down.

Secret codes and ADB-fine-tuning

For power users who want to have full control over energy saving, there are hidden tools:

Warning: Use of ADB-commands can lead to unstable operation of the system. Before experiments, make a backup through Settings → System system → Backup.
