Xiaomi smartphones are famous for their price-performance ratio, but even flagship models like the Xiaomi 14 Ultra or Redmi Note 13 Pro+ discharge faster than you would like. The reason is not only the battery capacity — it’s a matter of software optimization, background activity of applications and even the habits of the user. If your phone barely reaches the evening, do not rush to blame the battery: in 80% of cases, the problem can be solved with the MIUI settings without changing the battery.
In this article, we will discuss the unique MIUI 14/15 chips that the manufacturer does not advertise, but which can extend the autonomy by 30-50%. You will learn how to turn off hidden energy-consuming processes, which applications “eat” the battery even in standby mode, and why the standard “power saving mode” in Xiaomi works ineffectively. All methods are tested on models from 2022-2026 and do not require root rights.
Important: If your smartphone is running out too quickly (e.g., losing 20% in an hour in downtime), first check the battery status through the engineering menu (#4636##). Health value below 80% indicates physical wear and tear - in this case, no settings will help, you will need to replace the battery.
1. Hidden MIUI settings: what to disable in the first place
Xiaomi defaults to activate a number of features that speed up discharge but are not critical to the phone, which can be turned off without losing basic functionality.
- 🔍 Continuous synchronization of Mi Account. Even if you don't use the Xiaomi cloud, the system checks for updates every 15 minutes. → Xiaomi account → Synchronization.
- 📡 Search engine Wi-Fi/Bluetooth. Always look for networks in Wi-Fi settings and Bluetooth consumes up to 5% Turn it off if you don't have a car connection to your devices.
- 🎯 Adaptive brightness. Algorithm. MIUI often mistaken, overblown. It is better to adjust a fixed value (optimally — 40-50%) In Settings → Display. → Brightness.
- 🔄 Auto-update apps. Google Play → Settings → Select Auto Update Only via Wi-Fi or turn off completely.
Pay special attention to the functions of dual applications (for cloning messengers). Each copy of the application works as a separate process, doubling the battery consumption. If you do not use, delete the clones in Settings → Applications → Dual applications.
⚠️ Attention: On models with AMOLED-screens (e.g. Xiaomi) 13T or POCO F5) Black wallpaper actually saves you up to 8 percent a day, but only if you use a dark theme and wallpaper without bright elements. AMOLED, on the contrary, increase the cost.
2.Background activity optimization: which apps are "stealing" the battery
Even closed applications can use up their power through the background, and MIUI has a tool to control them, which is the battery and the performance, but it doesn't work well. Here's how to fix it:
- Go to Settings → Applications → Application Management → Battery.
- Select Background Limitation for all applications except messengers and navigators.
- For those who are particularly voracious (e.g. Facebook, TikTok), set a Deep Limit.
- Turn off AutoRun for unnecessary apps in the same menu.
The hidden battery eater is Google Play Services, which is responsible for syncing Google accounts, but often over-actively, to limit it:
- Go to Settings → Apps → All Apps → Google Play Services.
- Choose the Battery. → Limit background activity.
- Turn off Auto Update for this application.
Disable auto-start for social networks
Set a "Deep Limit" for Games
Restrict Google Play Services
Remove unused applications
Check the battery consumption in Statistics"-->
Another trick: if you use WhatsApp or Telegram, turn off Media Autoload (in chat settings) and these apps download photos/video in the background, which eats up to 15% of the charge per day.
3. Energy saving modes: which to choose and how to set up
MIUI has three power saving modes, but by default they don't work optimally.
| Regime. | Saving charge | Limitations | When to include |
|---|---|---|---|
| Balanced | 10-15% | Limits background activity but keeps notifications | Always, if you want a balance between autonomy and functionality |
| Super energy saving | 30-40% | Disables mobile Internet, notifications, background processes | When there is <20% charge left and you need to "pull" to the socket |
| Ultra energy saving | 50%+ | Only calls, SMS and 3 selected applications work | In emergency cases (for example, in nature without the possibility of charging) |
To enable Ultra Mode, go to Settings → Battery → Power Saving Mode → Ultra and select 3 apps that will work (e.g. Maps, Telegram, Camera). In this mode, the phone can last up to 3-4 days on 10% charge, but you will lose access to all other functions.
💡
In Ultra mode, you can temporarily turn off the restrictions by holding down the power button and selecting "Exit from energy saving." Useful if you need to use another application urgently.
On models with MIUI 15 (for example, Xiaomi 14), there is an Adaptive mode that automatically adjusts to your habits.
- Go to Settings → Battery → Adaptive energy saving.
- Turn on the switch and let the system analyze your actions.
- After 2-3 days, MIUI itself optimizes battery consumption for your use case.
4.Display settings: How the screen eats your battery
The display is the main consumer of power in a smartphone (up to 40% of total consumption), and Xiaomi has several hidden settings that will help reduce this figure:
- 🌓 Dark subject. + AMOLED. On the phones with AMOLED-In the dark theme, you can use screens (all flagships and most mid-range models) to save up to 20% on your charge. → Display. → Dark subject.
- ⏱️ Screen lock time. Reduce to 15-30 seconds in Settings → Display. → Sleeping after. Every extra minute adds 2-3% day-time.
- 🔄 Screen refresh rate: On models with 120 Hz (e.g, POCO F5 Or the Redmi Note 12 Pro.+) Switch to 60Hz in Settings → Display. → Upgrade rate. This saves up to 15 percent of the charge.
- 📱 Always-on Display (AOD). Turn off constant timelighting in Settings → Always-on Display and lock, even in "economical" mode AOD eat 5-7% nightly.
On the phones with LCD-screens (e.g. Redmi) 10A or POCO M5) The dark theme doesn't work, it's more important to reduce the brightness and the backlight time. Also check the Adaptive backlight settings in Settings. → Display: It often overstates brightness without needing to.
How to check the screen type on your Xiaomi?
Another secret: on models with MIUI 14/15, you can turn off the animation of the interface, which will reduce the load on the processor and, as a result, battery consumption.
- Activate Developer Mode (7 times click on the MIUI version in Settings → About Phone).
- Go to Settings → Additional → For developers.
- Find the points Window animation scale, transition animation scale and animator duration – set the value to turn off animation for everyone.
5. Communication and location: invisible charge eaters
Mobile, Wi-Fi, GPS and NFC are power-consuming even when you’re not using them, and can be optimized without losing functionality at Xiaomi.
- 📶 Network mode. If you have a weak signal (1-2 dividing, the phone uses a lot of energy to find it. 4G (or 3G, If the speed is not critical, then the settings → SIM-maps and mobile networks → Preferred type of network.
- 📍 Location accuracy. Turn off High Accuracy in Settings → Location → Mode, if you don't use navigation.
- 🔗 Roaming data transfer. Turn it off in Settings. → SIM-map → Roaming data if you are not traveling.
- 🔄 Wi-Fi Auto Connection. Open Network Connection in Wi-Fi settings is constantly scanning the air. Turn it off.
Pay special attention to NFC. If you don’t use contactless payments, turn off the module in Settings → Connections and Sharing → NFC. Even in passive mode, it consumes up to 3% of charge per day.
⚠️ Attention: On phones with two SIM-Xiaomi 13 Pro, Redmi Note 12 Dual SIM) second-second SIM Standby uses up to 10% of the charge. If you don't use the second card, turn it off in Settings. → SIM-map → Turn it off. SIM-map.
To maximize savings, use In-Air mode in uncovered areas (metro, underground parking lots) to prevent the constant search for the network, which eats up to 20% of the charge per hour. Remember to turn it back on!
6. Battery: How to extend its life for years
Even if you optimize all settings, the physical state of the battery is key, and Xiaomi has built-in tools to diagnose and protect it:
- 🔋 Battery status check. Enter ##4636## in the phone application, select Battery Information. Health setting should be >80%. If it's lower, the battery is worn out.
- ⚡ Charging restriction. In Settings → Battery → Battery settings enable Optimized Charging.This will limit the charge to 80%, extending the battery life by 2 times.
- 🔄 Calibration of the battery. If the phone suddenly turns off when 20-30%, Complete a full discharge/charging cycle (from 0% before 100% breaklessly).
- 🌡️ Temperature control: Do not use your phone when charging (especially for games) - overheating reduces battery life: 10-35°C.
On models with MIUI 15, we have a smart charging feature that analyzes your habits and adjusts the charging cycle, for example, if you normally take your phone off charging at 7:00, the system will stop charging by 80% at night and recharge to 100% before waking up.
- Go to Settings → Battery → Smart charging.
- Turn on the switch and allow access to the usage schedule.
- After 3-4 days, the system will adapt and start optimizing charging.
💡
Charging to 100% and discharging to 0% reduce battery life by 30%, and the optimal range is 20-80%.
If your Xiaomi is 2 years old and your battery is holding a charge for less than a day, check for bloating. To do this, put your phone on a flat surface and spin – if it swings, the battery is swollen and needs to be replaced immediately (this is dangerous!).
7. Additional chips: what else can be done
A few non-obvious ways to save charge, which few people know:
- 🎵 Turn off vibration. Vibromotor consumes a lot of power. Turn off vibration when typing and notifications in Settings → Sounds and vibrations.
- 📸 Camera optimization. When you're shooting video, turn off Stabilization and HDR (in the camera settings, unless they're critical, it'll cut the cost of the camera. 10-15%.
- 🔊 Reduce Bluetooth bitrate. If you use wireless headphones, in Settings → Connected devices → Select Sound Quality Priority: Balanced instead of High Quality.
- 🔄 Turning off automatic synchronization. → Accounts. → Autosynchronize data disable unnecessary accounts (Google, Mi, etc.).
On infrared phones (like Redmi Note 11), turn it off in Settings → Connections and Sharing → Infrared port if you don’t use the remote for the tech. Even in passive mode, it consumes energy.
If you often listen to music through the speaker, reduce the sound quality in the player settings (for example, in Mi Music, choose Balanced over High). 3-5% charge.
