Why is Xiaomi’s battery running out too fast?
Xiaomi smartphones based on MIUI It's famous for its functionality, but many users are faced with the same problem: the battery dies in a few hours of active use, and there can be many reasons, from background processes to hardware features.+ or POCO F5 s AMOLED-screens and high refresh rate consume charge more intensively than budget devices with IPS-matrix.
It's important to understand that the lithium polymer batteries (Li-Po) that Xiaomi smartphones use degrade over time. After 300 to 500 charging cycles, their capacity decreases by 20 to 30 percent. But even on a new device, you can experience rapid discharge if you don't optimize the settings. In this article, we'll discuss software and hardware methods that will help extend the battery life without compromising performance.
First, let's figure out what's eating up the charge. Go to Settings → Battery → Battery Use. Here you'll see a list of applications and system processes, ordered by consumption level. If Android System or MIUI Daemon are the first, the problem is the firmware, and if the leaders are TikTok, Google Maps or messengers, they need to be customized.
1. Optimize MIUI settings to save charge
MIUI offers a lot of power management tools, but by default, many of them are disabled, starting with the basic settings that will give the most effect:
- 🔋 Adaptive battery: turn on the settings → Battery → Battery mode → Adaptive: The system will analyze your habits and limit the background activity of unwanted apps.
- 🌙 Dark topic: on smartphones with AMOLED-screens (e.g. Xiaomi 13 Ultra or Redmi) K60 Pro) Black background reduces energy consumption by 15-20%. Activate it in Settings → Screen. → Dark subject.
- 🔄 Background activity restriction: go to Settings → Annexes → Application management → Autorun and disable autorun for unnecessary programs (especially social networks and instant messengers).
- 📶 Energy saving mode: in Settings → Battery → Battery mode select Energy Saving or Super Energy Saving (the latter disables background data and notifications).
Pay attention to the screen resolution and refresh rate. POCO X5 The Pro is the default price of 120 Hz and FHD+, But if you reduce it to 60 Hz, HD+, The operating time will increase by 25-30%. → Screen. → Screen resolution and refresh rate.
⚠️ Warning: Super Power Saving mode shuts down mobile data and synchronization, and only use it in extreme cases, such as when the charge is below 10% and you have to wait for recharging.

2.Setting up applications: who is to blame for the discharge?
Even if you don't use an app, it can consume a charge in the background, especially on social networks (Facebook, Instagram), messengers (WhatsApp, Telegram) and geolocation services (Google Maps, Yandex.Maps).
- 🚫 Background activity restriction: You can prevent background work for each application. Go to Settings → Annexes → Application management, select the program and turn off Background activity.
- 📍 Geolocation: Turn off permanent location access for applications that don't need it. → Confidentiality → Permits → Location.
- 🔔 Notifications: the fewer applications push notifications send, the less the processor wakes up. → Notifications.
- 🔄 Auto Update: In Google Play, turn off automatic app updates or allow it over Wi-Fi only (Settings) → Network → Auto-update of applications).
Pay particular attention to Google Play Services, which is a system process that often leads the charge consumption, to reduce its activity:
- Go to Settings → Apps → All Apps → Google Play Services.
- Press Warehouse and clear the cache.
- In the Battery section, select Limit background activity.
Xiaomi smartphones with MIUI 14+ firmware have a hidden feature called Deep Optimization, which forcibly closes the background processes. To activate it, type in the Phone app code ##4636## and select Battery Information → Menu (three dots) → Deep Optimization.
3. Communications Management: Wi-Fi, Mobile Network and Bluetooth
Communications are one of the major charge eaters, and if you optimize them, you can save up to 20 percent of your energy.
- 📶 Regime. 4G instead 5G: If your smartphone supports you 5G (for example, Xiaomi 13T or Redmi K50), But you're in an unstable area, switch to 4G. Continuous search of the web 5G It's very draining, and you can do that in Settings. → SIM-maps and mobile networks → Preferred type of network.
- 🔄 Automatic Network Search: Disable this feature in Settings → SIM-maps and mobile networks → Network Search (Select Manually).
- 📡 Wi-Fi and Bluetooth: turn them off when they're not needed. Even when they're in standby mode, they consume power. MIUI You can set up automatic Wi-Fi shutdown when leaving home: Settings → Wi-Fi → Additional settings → Turn off Wi-Fi in sleep mode.
If you use Bluetooth headphones or smartwatches a lot, look for audio codecs. AptX or LDAC codecs provide better sound quality but consume more power. Switch to SBC or AAC in your Bluetooth device settings to save charge.
| Communication module | Consumption (per hour) | How to reduce costs |
|---|---|---|
| 5G (network search) | 8–12% | Switch to 4G or turn off automatic search |
| Wi-Fi (active use) | 3–5% | Disconnect when downtime or use energy saving mode |
| Bluetooth (earphones) | 2–4% | Use SBC codec instead of aptX |
| GPS (constant switching on) | 10–15% | Disable background geolocation for applications |
⚠️ Note: If you use Xiaomi as an access point (modem mode), the battery will run out 2-3 times faster. Connect your smartphone to charge or use power bank.
4 Hardware Methods: How to Physically Extend the Life of a Battery
In addition to software settings, there are hardware factors that affect battery life, such as temperature: at temperatures above 35°C or below 0°C, the battery degrades 2-3 times faster.
- 🔥 Avoid overheating: Do not leave your smartphone in direct sunlight or near heat sources. Remove your case when charging if the phone is too hot.
- ⚡ Proper charging: Use Xiaomi’s original Quick Charge or HyperCharge chargers. Charging with left-hand adapters can cause overheating and accelerated battery degradation.
- 🔋 Charge level: try to keep the charge in the range of 20-80%. Constant charging to 100% and discharging to 0% reduce battery life.
- 📵 Storage: If you don't use your smartphone for a long time, charge it up to 50% and turn it off. Storing with a fully discharged or charged battery damages its capacity.
Some Xiaomi models (such as the Redmi Note 11 Pro+ or POCO X4 Pro) have an “Optimized Charging” feature that automatically stops charging by 80% if you plug your phone in overnight. Activates in Settings → Battery → Battery settings → Optimized Charging.
Calibration of the battery is another useful technique, and if the smartphone suddenly turns off at 15-20% charge, then the controller of the battery is not displaying its capacity correctly, to reset the data:
- Reduce the phone to 0% (until it turns off).
- Connect to the charger and wait 100% without turning it on.
- Turn off charging, turn on your smartphone and charge up to 100% again.
What to do if the battery is blown?
5. Hidden MIUI features to save charge
MIUI hides a few useful tools that few people know about, which help save charge without compromising convenience:
- 🔍 "Hidden Power Saving Mode: Enter the Phone code ##4636##, then select Battery Information → Menu (three dots) → Battery optimization. You can manually turn off background activity for system processes.
- 📱 "Light Mode: A simplified version of the interface that disables animations and background processes. → Special facilities → Easy regime.
- 🔄 "Synchronization limitation”: by default MIUI synchronizes data with Xiaomi servers (weather, themes, cloud). disable unnecessary synchronization in Settings → Xiaomi account → Synchronization.
- 🎯 "Smart schedule: If you go to bed and get up at the same time, set up automatic power saving mode for the night. → Battery → Schedule of energy saving.
Another secret is to turn off MIUI diagnostics, which is that the default device sends usage data to Xiaomi, which consumes charge and traffic, to turn off:
- Go to Settings. → The phone.
- Tap 5 times on the MIUI version to activate the developer mode.
- Back to Settings → Additionally. → For developers.
- Find the option to Disable the MIUI diagnostics and activate it.
On smartphones with a Qualcomm Snapdragon chipset (for example, Xiaomi 12 Pro or POCO F4 GT), you can further optimize the processor cores. To do this, in developer mode (Settings → Additional → For developers), turn off Windows animation and transition animation, and set Background processes to a Maximum 2 of the process.
💡
If the battery starts to sit down faster after the MIUI update, try resetting to factory settings (with data saved). Go to Settings → About Phone → Resetting → Reset settings.
6.Alternative methods: from root rights to battery replacement
If all of these things didn't work, maybe the problem goes deeper than that.
- 🔧 Getting root rights: You can remove unnecessary system applications (Mi Browser, Mi Video, GetApps) that consume charge in the background, but this voids the warranty and can lead to unstable smartphone operation.
- 🔄 Custom firmware installation: LineageOS or Pixel Experience firmware is often optimized better than standard firmware MIUI. But this method is only suitable for experienced users.
- 🔋 Battery replacement: if the battery capacity has fallen below 70% of the original (checked in Settings) → Battery → The battery status, it's time to change. The official replacement in the service center Xiaomi will cost 1,500-3,000 rubles.
- ⚡ External battery: for models with Quick Charge 4 support+ (for example, Xiaomi 11T Pro) Power bank with power output is suitable 30W+. They will allow you to quickly charge the smartphone on the way.
If you're rooting, we recommend using Magisk to manage the superuser, and then install Greenify, which will force you to freeze the background, but remember that:
⚠️ Attention: Root rights and custom firmware can lead to the blocking of banking applications (Sberbank, Tinkoff) due to security breaches, and the risk of infection with viruses also increases.
To check the actual capacity of the battery, use the AccuBattery app (available on Google Play) to show the actual wear and tear of the battery and help determine if it is time to change it; normal wear after a year of use is 10-15%; if the value is above 30%, the battery needs to be replaced.
💡
If a smartphone runs 10 to 15 percent off overnight on standby, the problem is most likely background processes or a worn-out battery, and if it discharges 3 to 5 percent, that’s the norm for most devices.
