How to Save Battery on Xiaomi: A Complete Guide

Modern Xiaomi smartphones, which are based on the MIUI shell or the new HyperOS, have impressive performance and bright screens, but these components are the most common causes of rapid discharge. Users often face a situation when the charge drops to a critical level by lunch, despite the fact that the device was fully charged in the morning. This is not always a sign of battery wear; often the problem lies in unoptimized system processes and aggressive work of background applications.

Understanding how the operating system manages power consumption can make a difference. Instead of buying an external battery or replacing a battery, you should first do a deep setup of the software. In this article, we will discuss specific steps that will help you save power and extend the battery life of your gadget without compromising basic functionality.

Many owners don't even realize that standard out-of-the-box settings are geared toward maximum performance, not energy efficiency. By changing a few key parameters, you can significantly reduce your energy consumption. Let's look at the basic optimization techniques that actually work in practice.

Analysis and management of background applications

The main energy eater of Xiaomi smartphones is apps that run in the background. Even if you're not using social media right now, they can constantly update your feed, track geolocation, or synchronize data. Android allows apps to behave fairly freely, but the MIUI shell provides powerful tools for control.

The first step is to look at the data in detail, go into the battery settings and see which programs consume the most resources, and often the apps that you don't use often come to the top of the list, and you have to limit the background activity so that they don't wake up the processor without your command.

⚠️ Note: Do not disable system applications such as “Security”, “Google Play Services” or “Mi Cloud” as this may cause the operating system to malfunction and loss of notifications.

To manually set the restrictions, go to the application menu and select the program you want, you can set the energy saving strategy here, you can use the "No Limits" mode only for instant notifications, and for the rest, choose "Smart Limits" or "Strict Limits".

• 📱 Open the Settings. → Annexes → All applications to access the list.
• ⚡ Select the app and click on Energy Savings.
• 🛑 Set strict restrictions for games and video editors.
• ✅ Leave the mode No restrictions only WhatsApp and Telegram.

Optimization of screen and interface

The display is the most energy-intensive element of any smartphone. On models with AMOLED arrays, the situation is aggravated by high brightness and refresh rate. If you have a flagship model with a frequency of 120 Hz, then switching to 60 Hz can add up to 15-20% of the time on a single charge, although visual smoothness of animations will decrease.

Dark theme is not only fashionable, but also useful for screens where each pixel is individually lit. In Black Theme, the black pixels just turn off, which saves energy. IPS-screens that are in the budget models of Redmi, the effect will be less noticeable, since the backlight works constantly throughout the area.

Also worth paying attention to is the screen timeout: if it's set for 2 or 5 minutes, the phone will burn in your pocket or on the table until you see it. The optimal value is 15 or 30 seconds. This is enough time to read the notification, but not enough for a significant discharge.

💡

Use the Read feature, which puts the screen in monochrome mode, which reduces eye strain and saves a little charge when reading books.

Connectivity settings: GPS, Bluetooth and Wi-Fi

Wireless communication modules are constantly scanning the surrounding space. GPS module is particularly demanding on energy because it interacts with satellites. Many applications request access to geolocation constantly, even when they are closed, which leads to the phone constantly searching for satellites, consuming precious charge.

Bluetooth can also be a hidden enemy of autonomy, especially if scanning devices for file transfer or connecting to wearable electronics are enabled.In modern versions of Android, Bluetooth and Wi-Fi scanning can work even with the main switches turned off, if use is allowed to improve geolocation.

To prevent power leakage, you need to go to advanced location settings, where you can turn off Wi-Fi and Bluetooth scans when the modules themselves are off, and it is also useful to restrict access to geodata for applications that are not critical, such as a calculator or voice recorder.

• 🛰️ Go to Settings. → Location → Access to applications.
• 🔍 Select "Only in Use" for most programs.
• 📡 Disable "Search for Wi-Fi" in advanced settings.
• 🔌 Turn off Bluetooth if you don’t use headphones right now.

⚠️ Attention: Full shutdown GPS may disrupt the operation of navigation applications (Yandex.Navigator, 2GIS) Taxi services, making them useless.

System functions of MIUI energy saving

Xiaomi engineers have implemented several levels of energy saving into their devices. The basic mode simply limits background activity, but there is a deeper setup. There is a "Saving Mode" switch on the battery menu that reduces processor performance and limits vibration.

The Ultra-Energy Saving feature deserves special attention, and when activated, the smartphone becomes a bell ringer: only basic functions (calls, SMS, alarm clock, calculator) remain, and the interface becomes black and white, which is ideal if you are on the go and need to keep the ability to make a call at all costs.

Also worth checking is the Mi Account and Google account sync settings. Frequent synchronization of photos, contacts and notes can keep the radio module active. If you don't need instant photo sync, set it up only over Wi-Fi or manually.

Hidden settings and disabling advertising

One of the features of MIUI is embedded advertising and a host of system services that collect data and display content, processes known as msa (MIUI System Ads) that consume Internet traffic and processor resources, and turning off ads is not only a matter of comfort, but also a way to save battery life.

To disable ads, you need to log into your security settings and find "Receive recommendations." You also need to disable personalized ads on your Google account, which will reduce the number of background requests to servers.

Settings → Passwords and security → Access to personal data → msa → Disable

Another important aspect is vibration and tactile response: constant vibration when typing or navigating a menu consumes the energy of the motor, and turning off the keyboard tactile response and system actions is an easy way to extend the life of the charge.

Extension of battery life

Saving charge is one thing, but it's also important to keep the battery healthy (SoH - State of Health). Lithium-ion batteries degrade from extreme temperatures and deep discharges. Try to keep the charge from falling below 10-15% regularly.

Using Xiaomi’s original chargers with Quick Charge or Power Delivery fast charging protocols is critical. Cheap cables and power supplies can produce unstable voltages that overheat the power controller and speed up battery cell wear.

Temperature also plays a role. Don't leave your phone in the sun or on the car panel in the summer. Overheating is the main enemy of battery chemistry. If the phone is hot while charging, remove the case and put it in a cool place.

• 🌡️ Avoid charging at higher temperatures +35°C and below 0°C.
• 🔋 Try to keep the charge in range 20-80% for everyday use.
• 🚫 Do not play heavy games while charging to avoid overheating.

⚠️ Warning: "Training" the battery in full discharge cycles of 0% and charge to 100% is only relevant for old Ni-Cd batteries. For modern Li-Ion, this is harmful and reduces the number of recharge cycles.

💡

The best use case is to put your phone on overnight charging with the optimised overnight charging option enabled, which pauses the charge at 80% and reaches 100% before you wake up.
