Power Savings on Xiaomi: A Complete Guide to Battery Setup

Xiaomi smartphones are known for their value for money, but even the most productive models of Redmi, Poco or Mi face one problem: fast battery discharge. When used actively, the charge can melt in front of your eyes, especially if you do not optimize background processes or include energy. In this article, we will discuss all the available ways to save energy on Xiaomi devices, including hidden MIUI settings, which the manufacturer does not advertise.

It's important to understand that saving energy is not just about turning on Battery mode, but also about a range of measures, from adjusting screen brightness to limiting applications in the background. We tested each method on different models, from the budget Redmi Note 12 to the flagship Xiaomi 14 Ultra, and found which ones have the maximum effect. For example, adjusting Adaptive Brightness correctly can save up to 15-20% of charge per day, and turning off unnecessary sensors β€” another 10%.

1. Standard energy saving modes in MIUI

The manufacturer has put three main energy saving modes in the MIUI firmware, which differ in the degree of limitation of functions, and can be found in the Settings menu β†’ Battery β†’ Battery Mode.

  • πŸ”‹ Balanced mode – optimizes consumption without strong restrictions, suitable for most users, as it saves notifications and background work of key applications (messengers, mail: ~10-15% charge.
  • πŸŒ™ Energy saving - limits background activity, reduces processor performance and disables autosynchronization. Notifications come with a delay. Savings: up to 30%, but lags in games are possible.
  • ⚑ Super energy saving is a last resort when the charge is below 15%, shutting down mobile internet, Wi-Fi and most background processes, leaving only calls and calls. SMS. Savings: Up to 50%, but the phone becomes a brick for everything but basic features.

Important: In Super Power Saving mode, some models (like the Poco F5) automatically turn off NFC and Bluetooth, which can prevent card payments or connecting to a smartwatch, and it resets Always On Display settings (if supported by your model).

⚠️ Note: On devices with Snapdragon 8 Gen 2 processors (e.g. Xiaomi) 13T Pro) Energy saving regime may lead to a decrease FPS In games up to 30 frames/sec. If you are a gamer, use Balanced Mode and optimize your consumption in other ways.

2 Hidden MIUI settings for advanced savings

In addition to the standard modes, MIUI has hidden features that are not visible in the main menu, and you need to activate them:

  1. Go to Settings β†’ The phone.
  2. 5 times click on the line version of MIUI (the notification will appear "You became a developer").
  3. Return to the main settings menu and open a new section for developers.

Now let’s look at the key options:

  • πŸ”„ Limiting background processes – set a value without background processes or a maximum 2 It's going to prevent unnecessary applications from running in the background: +2-3 self-dependency.
  • πŸ“Ά Turning off automatic network search - in the Mobile Network section, deactivate Network Auto Search. This will reduce the load on the communication module.
  • πŸ” Limit sensor activity - in For developers, turn off the Call Proximation Sensor and the Light Sensor (if you don't use autobrightness: +5-7% charge.
What happens if you turn off all the sensors?
Disabling sensors can lead to incorrect operation of some functions: - Without the proximity sensor, the screen will not go out during the call (risk of accidental pressing). - Without the light sensor, you will have to manually adjust the brightness, which is not always convenient. - The gyroscope and accelerometer affect the games and turn of the screen.

3. Screen optimization is the main "eater" of charge

The display consumes up to 40-50% of the power in active mode, and even if you don't use your phone, Always On Display (if any) or background notifications can drain your battery by 5-10% overnight.

  • πŸŒ“ Adaptive Brightness – Include it in Settings β†’ Display. β†’ Brightness, but set the maximum threshold for 60-70%. It'll save you up. 15% charge-free.
  • ⏱ Screen timeout – reduce the time to 15-30 seconds in Settings β†’ Display. β†’ Screen sleep. Every extra minute of backlight eats away" ~1% charge-hour.
  • 🎨 Dark subject. + AMOLED β€” screen-wise AMOLED (All Xiaomi flagships and most Redmi after 2020, black pixels are power-free. β†’ Display. β†’ Dark subject.
  • πŸ”„ Upgrade frequency – if you have a model with 120Hz or 144Hz (e.g. Poco) F5 Pro), set fixed 60 Hz in Settings β†’ Display. β†’ Frequency of upgrades. Savings: up to 25%!

πŸ’‘

In the models with LTPO-displays (for example, Xiaomi 13 Ultra) refresh rate automatically adjusts to the content, in this case, manual adjustment will not give an increase in autonomy, but only limit the smoothness of animation.

Always On Display (AOD) shows time and notifications even when the screen is off, but can drain the battery by 5-12% overnight. If autonomy is critical, turn off AOD in Settings β†’ Display β†’ Always On Display or set a schedule (for example, only from 8:00 to 22:00).

4.Application management: what drains the battery in the background

According to Xiaomi, up to 30 percent of the charge goes to the background of applications, especially aggressive social networks (TikTok, Instagram), instant messengers (Telegram, WhatsApp) and games.

  • 🚫 Autostart Limitation – Go to Settings β†’ Annexes β†’ Application management β†’ Autorun and disable autorun for unnecessary programs. for example, AliExpress or Wildberries should not work in the background.
  • πŸ”„ Battery Optimization – in the same menu (Application Management) select Battery Optimization and set Restricted Mode for all applications except messengers.
  • πŸ“΅ Disabling background Internet – in the settings of each application (for example, Settings) β†’ Annexes β†’ TikTok β†’ Mobile data) prohibit background data transfer.
  • πŸ—‘ Cleaning the cache – once a week, clean the app cache in Settings β†’ Warehouse β†’ Cleanup: Clogged cache causes system to waste more energy on data processing.

And the thing about gaming apps is that even when they're closed, they can leave behind the background, like Genshin Impact or something like that. PUBG Mobile continues to consume 5-7% It's charging per hour because of performance optimizers, to shut them down completely:

  1. Open Recent Apps (swipe up from the bottom edge of the screen).
  2. Find the game and swipe up, holding your finger for 1-2 seconds (forced closing).
  3. Go to Settings β†’ Applications β†’ Installed, find the game and click Forced Stop.

5. Saving charge when connecting to the network

Wi-Fi, Bluetooth, GPS and mobile internet can significantly reduce battery life if not optimized.

  • πŸ“Ά Mobile Internet – if the signal is weak (1-2 dividing, the phone spends up to 20% Extra power to find the network. 4G (turn off 5G) In Settings β†’ SIM-maps and mobile networks β†’ Type of network.
  • 🌐 Wi-Fi – Disable automatic connection to open networks in Settings β†’ Wi-Fi β†’ Additionally. β†’ Auto-connect to open networks. Also deactivate Wi-Fi Direct and WPS, if you don't use.
  • πŸ“ GPS geolocation – set Device Only (without using mobile data) in Settings β†’ Confidentiality β†’ Permits β†’ This will save you up to 10 percent of your charge.
  • πŸ”— Bluetooth – if you don’t use a smartwatch or headphones, turn off Bluetooth completely. ~3% charge per day.

To maximize savings, use In-Air mode in low-signal areas (metro, underground parking lots) to turn off all wireless modules and minimize consumption, and remember that you can manually turn on Wi-Fi or Bluetooth if you need them.

⚠️ Attention: On devices with two SIM-cards (Dual) SIM) One of them can stay active even in "In Airplane" mode if it's not manually disabled. β†’ SIM-maps and mobile networks.

6. Battery: How to extend the battery life

Saving energy is not just about extending the life of a single charge, but also extending the battery life. The lithium polymer batteries in Xiaomi smartphones degrade over time, losing capacity. Here's how to slow it down:

  • πŸ”‹ Avoid full discharge – do not allow the charge to fall below 10-15%. Optimal range β€” 20-80%. Complete cycle (0-100%) reduces the battery life of 1-2%.
  • ⚑ Do not use fast charging all the time – Fast Charge technology (33W, 67W, 120W) You heat the battery. Use standard RAM for everyday charging (10W-18W).
  • 🌑 Control the temperature – if the phone is heating up higher 40Β°C (for example, during games), remove the case and let it cool. Overheating accelerates the degradation of the battery in the 2-3 once.
  • πŸ“ˆ Calibration of the battery - once in a while 2-3 Complete a full cycle of discharge for the month (0-100%) to calibrate the controller, which will help to avoid incorrect display of the charge level.

In MIUI, there's a hidden Charging Optimization feature that automatically limits the charge to 80 percent to save the battery.

  1. Go to Settings β†’ Battery β†’ Battery settings.
  2. Find the option Charging Optimization (on some models it is called Battery Protection).
  3. Activate the function and set a schedule (for example, from 23:00 to 7:00).

πŸ’‘

Using charging optimization can extend battery life by 20-30%, but it requires discipline: you’ll have to connect your phone to charging more often, as it won’t charge to 100%.

7. Additional tips for maximum autonomy

If you are willing to take drastic measures, these tips will help you squeeze the maximum out of the battery:

  • 🎡 Turn off vibrations – the vibrator consumes up to 5% of the charge per day. Turn off vibration when typing and notifications in Settings β†’ Sounds and vibrations.
  • πŸ“Έ Limit the camera – use the camera (especially in mode) 4K or Pro) discharges the battery on 1-2% Reduce the resolution to a minute. 1080p camera-setting.
  • πŸ”Š Turn down the volume – speakers at full volume consume up to 3% Use your headphones or turn the volume down to 60-70%.
  • πŸ”„ Turn off automatic synchronization - in Settings β†’ Accounts. β†’ Sync Disable Auto Sync for unnecessary services (e.g. Mi Cloud, unless you are backing up).
  • πŸ“‘ Use the "Light version" mode of sites - in the Mi Browser or Chrome browser, turn on the option Save Traffic. This will reduce the loading load loading loading loading load on the processor pages.

For owners of infrared port devices (e.g. Redmi Note 11): turn it off in Settings β†’ Connected Devices β†’ Infrared port if you don’t use the remote for the equipment. Even in standby mode, it consumes ~1% of the charge per day.

FAQ: Frequent questions about energy savings on Xiaomi

❓ Why the battery is quickly discharged even in energy saving mode?
There could be several reasons: πŸ” Background processes - check in Settings β†’ Battery β†’ Battery use, which apps consume the most: Messengers or social media are often to blame. πŸ“‘ Weak signal, if the phone is constantly looking for the network, it drains the battery. 3G/4G manually. πŸ”‹ Battery wear – if the phone is older 2 In the years since, the battery capacity has decreased 20-30%. Check the battery status in Settings β†’ Battery β†’ Battery status.
❓ How to turn off advertising in MIUI, battery-discharger?
Advertising in system applications (Browser, Music, Themes) is not only annoying, but also wastes a charge on downloading content. To turn it off: Go to Settings β†’ About Phone and 5 times click on the MIUI Version. Go back to Settings β†’ Additional β†’ Special Features. Find Advertising Services and turn off all switches. We also recommend disabling Personalized Recommendations in Settings β†’ Privacy.
❓ Should you use apps to save battery from Google Play?
No, most of these applications (Battery Doctor, DU Battery Saver) not only don't help, but they also increase the charge consumption by running in the background. MIUI already has all the necessary optimization tools built in, except for the monitoring applications (AccuBattery), which help to monitor the state of the battery, but do not interfere with the operation of the system.
❓ Why After Updating MIUI The battery started to discharge faster?
It's a common problem: πŸ”„ Restart your phone – sometimes the background processes after the update work incorrectly. πŸ“± Reset the battery settings – go to Settings β†’ Annexes β†’ Application management β†’ Threefold β†’ Reset the battery settings. πŸ”‹ Calibrate the battery - discharge the phone to 0%, then charge to 100% without interruptions.If the problem persists, check the firmware reviews on forums (for example, 4PDA or XDA Developers.Maybe it's a bug that's going to be fixed in the next update.
❓ How to check which applications drain the battery?
MIUI has built-in monitoring: Go to Settings β†’ Battery β†’ Battery Use. Click on the chart and select a period (like β€œLast Charging”). See which apps are at the top of the consumption. If there are unused programs, limit their performance in the background. Use the AccuBattery app (available on Google Play) for detailed analysis. It shows real-time charge consumption and evaluates battery health.
