MIUI

In this article, we will discuss 12 Proven ways to reduce battery consumption, including hidden settings MIUI, All of these are hardware tricks and battery maintenance tips, all of which have been tested on the Redmi Note. 8 Pro with firmware MIUI 12-14 And we're going to focus on the problems that are specific to this particular model: overheating when playing, high consumption of MediaTek Helio. G90T c simple and charge-eating like com.miui.analytics.

Let’s just say: if your smartphone is discharged for 4-5 When used in moderation, the problem may be the physical wear and tear of the battery, in which case software methods will give you an increase in the amount of time you need. 10-15%. For an objective assessment, check the status of the battery through the engineering menu (##4636##) AccuBattery app – if the capacity has fallen below 80% From the nominal, it is time to think about replacement.

1. Optimizing background activity: what really eats charge

The main "eater" of the battery on the Redmi Note 8 Pro is not a screen or a processor, it's a background process. MIUI aggressively caches applications, and some system services (for example, miui.analytics or com.xiaomi.midrop) work around the clock, sending data to Xiaomi servers. 5-10% Charge per hour, and that’s not the norm.

The first thing to do is to disable auto-run of unnecessary applications:

1. Go to Settings → Applications → Application Management.
2. Slip on the three dots in the upper right corner and select AutoRun.
3. Turn off auto-run for instant messengers (except the main one), games, social networks and underutilized utilities.

Pay special attention to apps with constant sync: Facebook, Instagram, VK And Tinkoff Bank, they can consume up to 20 percent of the charge a day, even without active use.

Hidden threat: Google Play and Mi Cloud often wake up to sync to limit their appetites:

• 🔄 Turn off automatic sync of Google Account in Settings → Accounts. → Google → Synchronization of the account.
• ☁️ B Settings → Accounts. → Mi Cloud disable synchronization of unnecessary data (notes, calendar, records).
• 📱 Stop background activity for Google Play Services through Settings → Annexes → All applications → Google Play Services → Battery → Limit background activity.

💡

If after limiting background processes, you have stopped receiving notifications from messengers, add them to the list "No restrictions" in the battery settings.

2. Customization of the processor and graphics: how to reduce heating and consumption

MediaTek Helio G90T Redmi Note 8 Pro is a powerful but voracious chip, and in downtime, it can consume up to 300-400 MA, and when the load (games, video shooting) - up to 1.5 A. Fortunately, in MIUI There are hidden settings to limit productivity.

The most effective way is to turn on the power saving mode for the processor:

• 🔧 Go to Settings. → Battery and productivity → Battery mode.
• 🔋 Choose Energy Saving (not to be confused with Super Energy Saving, which disables background data!).
• 🎮 For games: in Settings → Special permits → Battery Optimization for Games Set Balanced Mode Instead of Performance.

For advanced users, there is a way to further restrict Helio G90T through the engineering menu:

1. Enter the code ##36446337## (Engineer Mode).
2. Go to Hardware Testing → MTK Settings → CPU Settings.
3. Install. CPU Governor in the meaning of powersave (instead of ondemand or performance).
4. For GPU (Mali-G76 MC4) choose simple_ondemand performance.

⚠️ Warning: Changes to the engineering menu can lead to unstable work. If after settings the smartphone begins to "brake" or overheat, reset the settings using ##4636## → Battery Information → Menu → Reset.

Another hidden charge eater is hardware acceleration of the interface.

adb shell settings put global window_animation_scale 0.5


adb shell settings put global transition_animation_scale 0.5




adb shell settings put global animator_duration_scale 0.5

These commands will reduce the duration of animations in half, which will reduce the load on the processor and graphics accelerator.

3.Screen: How to reduce consumption without losing comfort

Redmi Note Display 8 Pro with permission 2340×1080 technology IPS LCD consume 30% And you can save money on the day of use, but even here, you can save money without sacrificing convenience.

The main screen settings for saving:

• 🌓 Set adaptive brightness to 70-80% from maximum (c Settings) → Display. → Brightness).
• 🕒 Enable Dark Theme and tie it to the "dusk to dawn" graphic (Settings) → Display. → Dark subject. → Schedule).
• ⏱️ Reduce the waiting time to 15 seconds (Settings) → Display. → Sleep after).
• 🔄 Turn off screen autoturn (if not used frequently).

The Secret Trick: In MIUI is a hidden function DC Dimming, which reduces screen flicker and reduces consumption on 5-7%. To turn it on:

1. Activate Developer Mode (7 times tap the MIUI version in Settings → About Phone).
2. Back to Settings → Additionally. → For developers.
3. Find the option. DC Dimming and turn it on.

Please note: when activated DC Dimming can produce artifacts at low brightness. If it interferes, turn off the function.

For reading lovers: use reading mode (Settings) → Display. → Read mode, which filters blue light and reduces the load on the processor when working with text. 10-15%.

Brightness ≤ 80%|Dark theme included|Sleep time. ≤ 15 seconds|DC Dimming activated (optional)|Auto's offline.-->

4.Connection and Network: How Mobile Internet and Wi-Fi Steal Charge

Communications are the second-largest consumer of power after the screen, and the Redmi Note 8 Pro is particularly consuming in modes:

• 📶 Network search (if signal is weak).
• 📡 Constant connection to Wi-Fi and Bluetooth.
• 📶 Using mobile internet at speed LTE/4G (especially when loading).

Optimize network consumption:

• 📶 Switch to the switch. 3G (If you do not need high-speed Internet: Settings → SIM-maps and mobile networks → Preferred type of network → 3G.
• 🔄 Turn on the option to switch to mobile data in Wi-Fi settings so that the smartphone does not keep both modules active at the same time.
• 📡 Turn off Bluetooth and Wi-Fi overnight or when they are not needed (even in standby mode they consume) 50-100 mAh).
• 📍 Turn off High Accuracy in Location Settings (Settings) → Location → Regime. → Only the device).

For users of two SIM-If one of the cards is not used for calls / Internet, turn off its radio module:

1. Go to Settings. → SIM-maps and mobile networks.
2. Choose the unnecessary SIM-map and turn off.
3. For savings, also turn off 4G second SIM, If you only need it for calls.

Critical information: If your Redmi Note 8 Pro discharges for 2-3 When using the mobile Internet, check the settings → SIM-maps and mobile networks → Transfer of data → Access point (APN). Some operators (e.g. the Television)2) prescribe APN bearer=LTE, which keeps the module in force mode 4G even when idle.

5.Apps and services: who is to blame in the category

According to Xiaomi, the top-5 applications that consume battery on the Redmi Note 8 Pro:

1. Facebook (up to 25% charge per day)
2. Instagram (up to 20%).
3. Google Chrome (up to 15%).
4. Mi Video (up to 12%).
5. Tinkoff Bank (up to 10%).

How to deal with voracious applications:

• 🚫 Remove or freeze unnecessary apps (e.g. Mi Music, Mi Browser, GetApps). ADB: adb shell pm disable-user --user 0 com.miui.player
• 🔄 Replace standard applications with lightweight counterparts: Standard Application Alternative Charge Saving Mi BrowserBromite or Firefox Focus up to 30% Mi VideoVLC or MX Playerdo 25% Gallery Simle Gallery up to 20% CameraOpen Camera (with switched off) AI)15%
• 📦 Turn off notifications for unnecessary apps: Settings → Notifications → Management of notifications.
• 🔋 Include the Adaptive Battery in Settings → Battery → Battery settings (limits background activity of rarely used applications).

For games: if you play in PUBG Mobile, Call of Duty or Genshin Impact, enforced FPS:

1. In the game settings, set the schedule to Balanced and FPS on 30-40.
2. Enable Game Mode in the Notification Curtain (limits background processes).
3. Use Game Turbo (Settings) → Special functions → Game Turbo to optimize consumption.

⚠️ Note: Applications such as Clean Master or DU Battery Saver not only does not help, but also makes the situation worse, creating an additional load on the processor. MIUI already has built-in optimization tools – don’t install third-party cleaners".

Hardware methods: firmware, battery and temperature

If the software methods did not help, the problem may lie in:

• 🔋 Battery wear (capacity below 80%).
• 🔥 Overheating (normal temperature of Helio) G90T — 45°C, above - critical consumption).
• 📱 Outdated firmware (bugs in) MIUI may cause increased consumption).

What to do:

• 🔋 Check battery status via AccuBattery or engineering menu (#4636## → Battery Information: If health is below 80%, it is time to change the battery (original art. MBJ416660).
• 🔥 Watch the temperature: if the smartphone is heated above 45°C in plain, check: Are the air vents covered with a cover? Is the processor running at maximum frequency (check in the air vents). CPU Is there any dust surrounding the chamber (there is a radiator).
• 📱 Update the firmware to the latest version MIUI (Even if it's Global Stable, it's older. MIUI 12.5 Critical Helio intake bugs fixed G90T.

For advanced users: If you’re ready for experimentation, install a custom core like Perseus Kernel that optimizes Helio’s power consumption. G90T. However, this requires unlocking the bootloader and may deprive you of the guarantee.

Battery myths:

• ❌ "Remove phone to 0% once a month, harmful to lithium polymer batteries.
• ❌ "Charging at night spoils the battery — modern controllers turn off power at 100%.
• ✅ Truth: Optimal charge range — 20-80%. Avoid overheating higher 40°C when charging.

7. Additional tricks: from turning off vibration to calibrating battery

Non-obvious ways to save charge:

• 🔕 Turn off touch vibration and keyboard vibration (Settings) → Sound and vibration. That'll give you +3-5% day-load.
• 📞 Reduce vibration time when calling to 0.5 seconds.
• 🔔 Turn off camera shutter sound and system sounds.
• 📡 Turn on the plane mode for the night (if you don't wait for calls).
• 🔄 Calibrate the battery (once in a week) 3 Months: Discharge the phone before it automatically shuts down. Charge before 100% without interruption (use the original power supply) 18W). Hold on to the charger again. 1-2 hour 100%.

For users NFC: This module consumes ~10 mA/h even in the idle. If you don't use contactless payments, turn it off in Settings. → Connection and sharing → NFC.

Extreme mode: If you need to hold on to the last percent, activate Super Energy Saving (Settings) → Battery → Super energy saving. It turns off:

• Mobile Internet (only calls remain)/SMS).
• Wi-Fi and Bluetooth.
• Background activity of all applications.
• Animations and vibrations.

Often the fault of bugs in new versions MIUI, Especially in the Global Stable. MIUI 13.0.4 was a bug with a constant operation of the module GPS.
