Owners of smartphones Xiaomi, Redmi and Poco often face aggressive optimization of the MIUI and HyperOS. Built-in energy saving algorithms can force the closure of applications, block notifications and limit background activities, which prevents the full operation of the device.
Particularly annoying is the maximum energy saving mode that turns a modern gadget into a simple button phone with limited functionality, the screen becomes black and white, and only calls and messages remain available.
In this article, we will discuss how to correctly deactivate these restrictions to return the smartphone to full performance and stable operation of all applications.
Why the smartphone is going into austerity
MIUI is designed to maximize battery life, sometimes at the expense of user convenience, and when the charge falls below a certain threshold or a special mode is activated, a severe restriction of background processes is activated.
This is necessary if you are on a trip and it is important to keep the ability to call, but in everyday use, such measures often become excessive and interfere with the normal operation of messengers and navigators.
It’s worth noting that there’s a difference between a conventional power saving mode and maximum savings: the former simply reduces the brightness and frequency of updates, while the latter actually blocks most installed applications, leaving only the system minimum.
Understanding the logic of the shell avoids accidentally activating these functions, often by users turning on the mode themselves without realizing the consequences, or it activates automatically when the charge is low.
⚠️ Warning: Forced shutdown of system restrictions could lead to faster battery discharge during the day if exceptions for important applications are not configured.
Basic shutdown through notification curtain
The fastest way to get your phone back to normal is to use a quick access panel, which is true if the device is already in confined mode and the interface is greatly simplified.
Swipe down from the top of the screen to open the control center. Find a tile called "Saving Mode" or a battery icon. If the tile is on green or blue, the mode is active.
Click on it once to deactivate. The system immediately returns the standard wallpaper, color interface and unlocks all applications. This action only removes the current state, but does not change the settings of automatic on.
If a simple click doesn't help or the tile is missing, you need to go to a deep settings menu, where you can control the behavior of the system in more detail and prevent re-energization.
💡
If the save mode tile is missing from the curtain, click on the three dots in the corner of the control panel and select "Edit" to return the icon to a prominent place.
Setting the parameters in the battery menu
For a more nuanced setup, go to Settings → Battery and Performance. This is where the basic power management levers of your Xiaomi or Redmi are.
At the top of the screen, you'll see a slider or a choice of mode of operation, switch it from "Maximum Savings" to "Balanced" or "Production" that allows the system to allocate resources independently.
You can also see the "Energy Saving Mode" option on the same menu, and click on it to see the list of applications, and you can configure what programs will work without restrictions, even if the general saving mode is on.
It's important to set the autonomy of apps right, and if you turn off the limitations on messengers, they'll arrive on time, even if the phone decides to save power.
☑️ Checking battery settings
Autostart and Background Process Management
Aggressive MIUI optimization often kills processes that users think are important, and it's not enough to open an application to be stable.
Go to the Safety app (green lightning icon) and select the Permissions section and find Autostart, where you need to turn on switches for those programs that are supposed to start with the system.
Next, go to the settings of a specific application through the “Applications” menu» → «All apps. Find the right software, select Battery, and set the value "No Limits." This is critical for email clients and trackers.
Also check settings in Settings → Applications → Permissions Management → Other permissions. Make sure important programs have the right to “Massage in the background.”
| Type of restriction | Where to find out. | Recommended action |
|---|---|---|
| Auto-start | Security → Permits | Enable messengers |
| Background work | Application settings → Battery | Select "No Limitations" |
| Cleaning up memory | Settings → Advanced → Memory | Add to exceptions |
| Sleep regimen | Settings → Lock screen | Disable for important apps |
⚠️ Warning: Completely disabling background restrictions for all applications at once can lead to a significant reduction in device life from a single charge.
Why are apps still flying out?
Disabling Optimization through the Developer Menu
For advanced users, there is access to hidden features through the developer menu, which allows you to disable deep optimization MIUI Optimization, which is often the cause of problems.
To enter the menu, go to Settings → About Phone and quickly click 7 times on the MIUI Version (or OS Version) and the message will appear “You became a developer”.
Now in the settings menu will appear a new section “Advanced settings» → «For developers. Find the item "Enable optimization" MIUI» And you turn it off. The phone will alert you to the risks and reboot.
Once the system is restarted, it will work differently: notifications will come instantly, but battery consumption may increase. Use this method if standard methods do not help.
The path to hidden settings:
Settings → About Phone → 7 Clicks → For Developers → Enable MIUI Optimization (Off)Impact of system updates on energy saving
With each update to HyperOS or MIUI, the battery algorithms change, and sometimes new versions bring bugs that cause a false switch on savings.
If you notice strange behavior on your phone after the update, try resetting your battery settings. This won't delete your data, but will return power consumption to factory values.
Watch the flow statistics. It's often the case that one particular application causes heat and discharge, causing the system to turn on the defense mechanisms, and then the problem is the culprit, not the system.
Check for updates to the apps themselves in Google Play or GetApps. Developers often release patches that fix incorrect behavior of background services on new versions of Android.
💡
Updating applications and systems on time is the best way to avoid conflicts between software and energy saving algorithms.
