How to find out the time of the Xiaomi Redmi phone: full analysis

Xiaomi Redmi smartphones are famous for their autonomy, but over time, each user faces the need to check how much time the device spends in active mode, this may be necessary to diagnose fast discharge, check the honesty of the seller when buying a used gadget, or simply to self-monitor digital well-being. MIUI operating system and its new version of HyperOS are hidden many tools for monitoring activity.

There are several levels of access to this information, from standard settings that everyone can see, to deep engineering menus where the average user should not look unnecessarily, and we'll take every method available so you can get the most accurate data on how your battery is used, and understanding these processes will help extend the life of the device.

It's worth noting that the data in different parts of the system can vary slightly, as they are maintained by different system services. Screen life and total battery life are two different parameters that are often confused: the first shows how many hours the display was on, and the second shows how long it has been since the last full charge.

Standard statistics in battery settings

The most obvious and affordable way to get information about energy consumption is through the built-in stats menu, which is available on all models, from the budget Redmi Go to the flagship Redmi K series. To get there, you need to go to Settings and select Battery, which shows the total charge percentage and the approximate time remaining until discharge.

However, for detailed information, you need to click on the settings icon (usually three dots or a gear in the corner) and select Battery Statistics. In this section, the system shows the discharge graph for the last 10 days. It is important to understand that the graph is reset with each full charge to 100%, so you will not get a general history over the entire lifetime of your phone.

At the bottom of the screen, you'll see a list of apps sorted by energy consumption, and if you click on a particular app, you can see a detailed breakdown of how long it was in the background and how long it was on, which helps you to uncover the hidden processes that are imperceptibly planting the battery, even when you're not using the phone actively.

• 📊 Consumption chart shows peak activity during the day.
• ⏱ Screen on Time (Screen on Time) displays real time usage.
• 🔋 Residual time is calculated by algorithms based on the current rate of discharge.
• 📱 Application statistics allow you to find parasitic programs.

⚠️ Note: The data in standard statistics may be inaccurate if you have recently updated your firmware or reset your settings to factory. 2-3 day to calibrate learning algorithms.

For most users, this information is enough, but if you want to get more technical data, you should pay attention to the hidden features of the system. In particular, Android stores usage logs that are not always displayed in beautiful graphs of the MIUI interface.

Using Digital Well-Being to Analyze

Starting with Android 9 and newer versions of Xiaomi shells, the Digital Wellbeing tool is introduced, which is designed to monitor the time spent on your smartphone rather than diagnosing the battery, and to find the most accurate data on how many hours a day you keep your device on.

To access this information, go to Settings → Digital Well-Being and Parental Control. The center of the screen is usually a pie chart showing the total usage time for today. Clicking on it will give you an hourly breakdown, which is the perfect tool for anyone who wants to know the actual phone time in their hands.

Unlike standard battery statistics, this section doesn't reset after charging. It keeps a calendar record. You can flip through a week or a month ago and see how much time you spent on your phone on a particular date, and it's especially useful for comparing activity on workdays and weekends.

In addition, the menu features Wind Down, which puts the screen in black and white and blocks notifications at a given time. Statistics here are often more honest, since it reads the data about the display on at the system level, ignoring the processes that work in the background without displaying an image.

• 🕒 Accurate time count by hours and minutes for each day.
• 📉 Comparison of periods allows to estimate the dynamics of use.
• 🔔 Notifications about exceeding limits help control habits.

Checking the time of inclusion through the engineering menu

For advanced users who want to know how long the phone has been on since the last reboot or even since (factory build), there is an engineering menu available on Xiaomi phones via a special code in the Phone app.

Dial the code ##4636##. If the menu opens, select Usage statistics, which shows the time since the last boot and, in some firmware versions, the total time, but newer versions of MIUI 13/14 and HyperOS often block access to this code.

If the code doesn't work, you can try an alternative way through the developer's settings, by clicking 7 times quickly on the MIUI version in About Phone, then in the advanced settings, find the Debugging over USB and activate it, sometimes allowing access to additional logs.

adb shell dumpsys batterystats --reset

This command, which is typed in through a computer with an ADB installed, resets the battery statistics, allowing you to start counting again for the purity of the experiment, but you can use the command to view the current uptime.

adb shell cat /proc/uptime

The result is the number of seconds that have passed since the system kernel was loaded, and dividing it by 3600 gives you the exact number of hours you can run without rebooting, which is a critical parameter for diagnosing freezes: if the phone runs for weeks without rebooting, it can indicate an accumulation of errors in RAM.

⚠️ Warning: Do not change the values in the engineering menu unless you know exactly what they are responsible for. Incorrect settings can lead to unstable operation of the radio module or rapid wear of the battery.

Analysis of charging cycles and status of the battery

Unlike the iPhone, Xiaomi doesn’t have a simple “Battery Status” button that shows the percentage of wear and tear, but you can find out the number of recharge cycles and the current capacity through system logs or special applications.

One way is to use an AccuBattery app or analogues that, running in the background for a week, calculate the actual battery capacity, but there's a faster, if less accurate, method through a hidden menu. Type in the code ##6485##.

In this table, we're interested in a few parameters. MB_06 — This is a battery health condition where you say "Good" or percentage. MB_00 The current charge is in percentage, and MF_02 (or MF_05 It shows the number of complete charging cycles, depending on the model. The charging cycle is the total consumption. 100% containers, not necessarily at one time.

If the number of cycles exceeds 500-800, the actual battery capacity may be less than 80% of the factory, in which case the life of the Redmi phone will be significantly less than the stated, even if the screen statistics show few hours, this is the physical wear and tear of the chemical source of current.

💡

For maximum accuracy of the data in the ##6485## menu, turn off the charger before checking. Some settings are displayed correctly only in the discharge mode.

Third-party applications for detailed monitoring

Android’s regular tools don’t always get the full picture, and third-party developers have built powerful utilities that can read system logs deeper than standard settings, and one of the leaders in this niche is the BetterBatteryStats app, or GSam Battery Monitor.

These programs require special permissions through ADB (Android Debug Bridge) on the first run, and after connecting to your computer and entering the permission command, the application accesses batterystats.bin statistics, which can show which wakelock keeps the phone awake.

It's often the case that the screen is off, but the phone is warming and draining. Standard statistics will show "The screen is off," but they won't tell you why. Specialized snails will point to a specific process, like "Google Play Services" or "Sync," which keeps the processor active, which eliminates the cause of the quick discharge.

• 📲 Access to root is not always mandatory, enough rights ADB.
• 📈 Voltage graphs help assess battery health.
• 🚫 Blocking wakelock can significantly increase standby time.

Using these tools requires some technical literacy, but gives the most complete picture of what is happening inside the smartphone. For the average user, it may be enough to install a light version without complex settings, just to view general statistics.
