How to optimize battery life on Xiaomi

Owners of Xiaomi, Redmi and Poco smartphones often face a paradox: with a huge battery capacity, the device discharges faster than expected. This is due not so much to physical wear and tear, but to aggressive algorithms for energy saving the shell MIUI or HyperOS. The system seeks to complete background processes to save resources, but sometimes does it too zealously, turning off the necessary notifications, or, conversely, allows “vulsive” applications to work without restrictions.

Understanding how Android manages power on a Chinese manufacturer’s devices can significantly increase battery life. Reducing the screen refresh rate from 120 Hz to 60 Hz can increase the smartphone’s life by up to 20% without losing functionality. In this article, we’ll look at specific steps to help you take control of power consumption under your supervision, eliminating unnecessary charge wastage.

Many users mistakenly believe that installing third-party cleaners will solve the problem, but in the Xiaomi ecosystem, embedded tools work much more efficiently than any analogue from the Play Market. Competent configuration of system parameters can work wonders even on models of the past.

Analysis of consumption and identification of energy eaters

The first step to optimizing should always be diagnostics. Don't wonder which application is landing the battery when the system provides detailed statistics. Go to Settings → Battery and Performance to see the discharge graph. It's important to pay attention not only to the percentage ratio, but also to the time in the background.

It often turns out that social networks or instant messengers consume disproportionately many resources due to the constant attempts to sync or play media files in the background. Background activity is the main enemy of autonomy in modern smartphones. If you see an application that you rarely use, but it is at the top of the list, its settings need to be revised.

Note the screen time parameter, which is low, and the battery goes down, so the problem is that it's background processes or poor cellular signal, and when you're under coverage, the communication module is running at its limits, which dramatically increases power consumption.

• 📊 Check the statistics for the last 24 hours and 10 days to identify trends.
• 📉 Pay attention to applications with a high percentage of backgrounds.
• 📡 Make sure that high consumption is not associated with a bad network signal.

Customization of the screen and interface MIUI

The display is the most energy-intensive component of any smartphone, and Xiaomi is no exception. Modern AMOLED and IPS matrixes require competent management of brightness and refresh rate. Automatic brightness often works incorrectly, leaving backlighting at maximum indoors. It is recommended to manually set a comfortable level or adjust a timer for turning off backlights for 15-30 seconds.

The feature that deserves special attention is the “Update Frequency” feature. Owners of models with screens of 90 Hz, 120 Hz and above often leave the “Default” or “Maximum” mode. Switching to the standard 60 Hz in the Settings menu → Screen → Update frequency significantly reduces the load on the processor and graphics accelerator. This is especially true when reading books or static web pages.

💡

Use a dark topic not only for the purpose of AMOLED-screens, but also to reduce the overall load on the eyes and processor when using at night, even if you have a computer. IPS matrix.

It’s also worth turning off or minimizing the use of Always-On Display (AOD) – although it looks spectacular, it keeps the screen from fully plunging into deep sleep – and setting up your AOD schedule, such as from 8:00 to 23:00, will help save you charge at night when you sleep.

⚠️ Warning: Do not install live wallpapers (weather widgets, animations) on the main screen if your goal is to maximize savings. GPU and processor, even when you are not interacting with your smartphone.

Background Process Management and Auto Start

One of the key features of the MIUI shell is that it has strict control over the applications it runs. However, some programs require special permissions to work properly, and users often give them to everyone. Go to Settings → Applications → Permissions → Autorun. Leave only messengers and alarms that really need to work in the background on.

For each installed application, you can configure an individually energy saving strategy. From the Settings menu → Applications → All applications, select the desired program, click on “Charge Saving” and select “Limit background activity” mode, which will prevent the application from taking actions when it is folded, which is critical for gaming platforms and stores.

Don't forget the Advanced Cleanup feature in the Security app, which allows you to close processes that consume energy in the background with a single tap, but don't do it fanatically, as constantly restarting heavy applications (such as a navigator) can require more power than their background waiting.

• 🚫 Turn off auto-start for all unnecessary utilities.
• ⚙️ Set background activity limits for resource-intensive games.
• 🧹 Use the built-in optimizer regularly in the Security app».

Network connections and communication modules

Networking is one of the most energy-intensive processes. If you're in a hot spot, your smartphone is constantly switching between the towers, causing heat and quick discharge, and in such situations, it's wiser to temporarily turn on Flight Mode or switch to only 2G/3G if the Internet speed is not critical.

Use of fifth generation networks 5G where the coverage is unstable or lacking, it is also causing rapid discharge.If you are not taking advantage of high speed right now, it is better to switch to mode Preferably LTE via the Settings menu → SIM-maps and mobile networks, which will reduce the load on the modem.

Geolocation (GPS) is another important consumer, and many applications request access to Always location even when it is not necessary. Go through the permissions and set the "Only in Use" option for most programs, which will prevent constant satellite surveys in the background.

Special functions and hidden settings

Xiaomi has a few specific features that can both help and harm autonomy, such as Memory Extension, which uses a portion of internal storage as RAM, can increase power consumption due to more frequent access to the drive. If you have enough physical RAM (8 GB or more), this feature is best turned off in the Additional → Extension section.

Also worth mentioning is the MIUI Optimization feature in the developer menu, which can change the behavior of the system, but for the average user, it rarely gives a battery boost, but rather disrupts the interface. It is much more effective to turn off Device Search in the Google and Xiaomi Account settings, since these services constantly scan the environment.

💡

Disabling advertising identifiers and personalization services in your Mi Account reduces the number of background requests to servers, which has a positive effect on work time.

And let's not forget the vibration. The taptic feedback uses the vibrator every time you touch it, and in models with a conventional vibrator motor (not a linear one), you can feel it, and you can turn off the vibration when you type in the keyboard settings or in the general audio settings.

⚠️ Warning: Do not use third-party applications to “cool” or “speed up” the battery.They are often viruses or miners themselves that load the processor, causing the opposite effect.

Operation and charging rules

The physical state of the battery directly affects how long it holds charge. Lithium polymer batteries used in Xiaomi do not like extremes. Try not to discharge the smartphone to 0% and not to hold it constantly at 100%. The optimal range for a long life chemistry is from 20% to 80%.

Using the original charger and cable is critical. Cheap analogues may not support Quick Charge or Power Delivery fast charging protocols, which takes longer and with high heat, which harms the battery. Also avoid using your smartphone while charging, especially in heavy games, as the combination of heat from the processor and battery charge is the fastest way to degradation.

If the smartphone is not used for a long time, leave the charge at 50-60% and turn it off. Storage of a fully discharged device can lead to a deep discharge, after which the power controller will block charging, and the gadget will be “revived” only in the service center.

• 🔋 Keep the charge in range. 20-80% maximum service life.
• 🌡️ Avoid overheating the device, do not leave it in the sun.
• 🔌 Use certified cables and power supplies.
