How to turn on power savings on Xiaomi: Full Instruction

Owners of smartphones Xiaomi, Redmi and Poco often face the need to extend the autonomy of the device at the most inopportune time. the shell MIUI or the new HyperOS have powerful built-in tools for power management, but not all functions are active by default.

In this article, we will take a look at all the ways to optimize power consumption, from basic switches in the notification curtain to deep tuning of background processes, learn how to control “gluttonous” applications and understand how the adaptive battery works in the Android system, which will help you avoid sudden discharge in a critical situation.

Before we go to any drastic measures, we need to assess the current state of the battery, and the system provides detailed statistics that show which software consumes the most resources, and understanding this data is the first step to effectively managing the energy of your smartphone.

Basic activation of the energy saving mode

The fastest way to extend battery life is to use standard saving mode, which is available in any smartphone brand and activates in just a few touches, which is ideal when the charge drops below 20%, and you need to reach the evening or find a socket.

To turn on, open the Security app (green icon with shield) that is preinstalled on all Xiaomi devices. At the bottom of the screen, look for the Battery item. Here you will see a slider for saving mode activation. When it is turned on, the system will automatically limit background activity, reduce brightness and turn off data synchronization.

There's also an alternative way through the control center: swipe down from the top right corner of the screen to open the curtain. Find the Battery icon or Energy Saving. If it's not on the first page, click on the edit pencil and add the widget to the active zone.

It’s important to note that standard saving mode doesn’t affect the basic applications you use right now, it only stifles background processes, but if the situation is critical, you can activate Ultra Mode (or Flight Mode in some firmware versions), which turns your smartphone into a regular caller, leaving only calls and SMS available.

Set up background activity restrictions

The main charge eater in modern smartphones are social networks and messengers that work in the background. The MIUI shell allows you to flexibly adjust the behavior of each installed application. It is a more subtle tool than global energy saving.

Go to Settings → Applications → All Apps. Select the app you want (like a news aggregator or a game you rarely use). Find Energy Savings. There are three options available here: No Limits, Energy Savings, and Severe Limitation.

By choosing a Hard Limit, you prevent an application from running itself. Notifications won't come until you open the program yourself. It's a great way to stop the background loading of content in applications that don't require instant response.

⚠️ Note: Do not set a “Strict Limit” for instant messengers (Telegram, WhatsApp) or email clients if you need to receive notifications of new messages on time. Otherwise, messages will only arrive after opening the application.

You should also pay attention to AutoRun. Security → Permissions → AutoRun can prevent programs from starting with the system. Leave autorup only for vital services.

Optimization of screen and interface

The display is the most energy-intensive element of any smartphone, accounting for 40-50% of all charge consumed, and on Xiaomi devices with AMOLED screens, the savings are much wider than on models with IPS-matrixes.

The first thing you need to do is set the screen timeout. Go to Settings → Screen and Brightness → Sleep mode. Set a value of 15 seconds or 30 seconds. This will prevent the screen from burning if you forgot to lock the phone after use.

Owners. AMOLED-In these matrices, black means the pixel is off, which actually saves energy. → Screen and brightness → Dark mode.

• 🌑 Always On Display: Turn off the Always On screen or set it up for only 10 seconds after touching so you don’t waste your charge.
• 📉 Update frequency: If you have a 90Hz or 120Hz model, switch to Standard (60Hz) to make the interface less smooth, but will significantly extend the autonomy.
• ☀️ Adaptive brightness: Turn on automatic brightness control so that the light sensor does not allow the screen to shine at full power in a dark room.

Another important parameter is the frequency of the sensor survey. In the Black Shark or Redmi K series, this setting can be made in a separate menu, but in most cases it is enough to simply avoid high-performance modes in everyday tasks.

Management of network modules and geolocation

Network search and constant data exchange with servers is a hidden but powerful energy drainer. If you are in the zone of insecure reception, the smartphone starts to work at the limit of the antenna's capabilities, which leads to rapid heating and discharge.

First of all, check your geolocation settings. Many applications request access to GPS constantly, even when not in use. Go to Settings → Location. You can turn off geolocation completely or configure access for each application separately by selecting Only when in use.

For mobile, in low-flight (1-2 division), it is better to switch to 3G/2G mode or turn on Flight Mode if calls are not important. Constantly searching for a tower in the 4G/5G standard "eats" the battery faster than a stable but slow 3G.

The Wi-Fi Assistant features, which scans networks in the background even when Wi-Fi is off, and turn off this option in the advanced Wi-Fi settings to stop constantly searching for networks in range.

Advanced settings and hidden functions

For advanced users, MIUI and HyperOS have additional controls, which are not obvious, but allow you to maximize efficiency, and these methods require caution, because they can limit the functionality of the system.

One of these features is Advanced Power Saving, which is on the battery menu, and activating this can limit the CPU clock speed and shut down some system services, and the phone will be slower, but it will live longer.

💡

Use Do Not Disturb at night, which not only blocks calls, but also often turns off data and vibration, saving you charge while you sleep.

Also worth checking is the list of running processes. The Security app has a memory cleanup feature. While Android manages RAM itself, periodic cleaning of heavy applications that have been getting stuck in the background can have a positive effect on autonomy.

⚠️ Warning: Do not use third-party Task Killers apps from the Play Market. They often run worse than Android’s built-in mechanisms, causing system processes to restart and, as a result, even more battery consumption.

If you use Always-On Display, set it up, let it light up only during the day, from 8:00 to 23:00, and shut down at night, and that saves a few percent of the charge per night.

Diagnostics and maintenance of the battery

Software settings are powerless if the physical wear of the battery has reached a critical level. Lithium-ion batteries lose capacity after 500-800 charge-discharge cycles. If your smartphone is more than 2-3 years old, no optimization will return it to factory autonomy.

Built-in function of accurate display of battery health (in percent) in MIUI It's been gone for a while, but in newer versions, it appears in the battery menu ##6485## In the engineering menu that opens, find the parameter. MB_06 (battery condition) or RF_Batt_Voltage.

• 🔋 Charge cycles: Try not to drain your phone to zero or keep it on charge all the time.The optimal range for a long Li-Ion life is from 20% to 80%.
• 🌡️ Temperature: Do not charge your smartphone under your pillow or in the sun. Overheating irreversibly destroys the chemical structure of the battery.
• ⚡ Original cables: Use certified cables and power supplies. Cheap analogues can supply current unstablely, causing voltage surges.

If the diagnostics show that the capacity has dropped below 70-80% of the face value, the only effective solution is to replace the battery in an authorized service center.

💡

Integrated approach to customization: The combination of dark theme, background limitations and moderate screen usage gives a better result than simply turning on one save mode.

Check your consumption statistics regularly, and if you notice that an app suddenly consumes 30 percent of its energy in an hour, even though you haven't used it, that's an excuse to delete it or check for viruses.
