How to quickly discharge the battery on Xiaomi Redmi: safe and effective ways

Sometimes Xiaomi Redmi users need to discharge their battery quickly, whether for battery calibration, battery testing or repair preparation. However, standard smartphone use (social networks, instant messengers) discharges it too slowly. In this article, we have collected 10 proven methods that will speed up the process by 2-5 times without harming the device.

It's important to understand that fast discharge is stressful for a lithium-ion battery. Excessive heat generation or deep discharge (below 3%) can shorten its lifespan. So we've ruled out dangerous ways like heating the battery or using damaged chargers. All recommendations have been tested on Redmi Note 10/11/12, Redmi 9/10 and POCO X3/X4 models, but will also be suitable for other Xiaomi Android smartphones.

If you need to discharge your phone to 0% to diagnose or replace your battery, monitor your charge level through Settings → Battery → or widget on the home screen. Don’t let the device shut down completely – this can cause your MIUI file system to crash.

1. Game mode + maximum brightness: discharge in 1-2 hours

The safest and most efficient way is to combine graphically loaded games with increased screen brightness. Modern Qualcomm Snapdragon chips (for example, in Redmi Note 11 Pro+) or MediaTek Helio (as in Redmi 10C) in game mode consume up to 8-12 watts of power, which is 3 times more than when watching video.

Algorithm of action:

• 🎮 Install a heavy game: Genshin Impact, Call of Duty: Mobile or PUBG (they're maximally loaded GPU).
• ☀️ Increase the screen brightness to 100% in the notification curtain.
• ⚡ Enable Game Mode in the game settings (disables power optimization).
• 🔥 Run the game at maximum graphics settings and play 30-60 minutes.

To speed up the process, turn off Adaptive Brightness (Settings → Display) and Dark Theme – they reduce energy consumption. You can also turn on Performance Mode in Settings → Special Features → Performance Mode (available on MIUI 13+).

2. Simultaneous launch of multiple applications

Multitasking is another way to boost the charge: Modern Xiaomi smartphones support the simultaneous operation of several applications in split screen or floating windows, which increases the load on the processor and RAM.

How to do this:

1. Open YouTube and play your video at maximum resolution (1080p or 4K).
2. Activate Picture-in-Picture Mode (swipe down video → PiP icon).
3. Open Google Maps with navigation (enable it) 3D-look).
4. Launch Telegram or WhatsApp with active video chat.
5. Enable the Wi-Fi Hotspot (Settings → Access Point).

This approach creates a combined load:

• 📹 YouTube video loads the decoder.
• 🗺️ Google Maps is working GPS processor.
• 🔥 Hot spot increases power consumption of Wi-Fi module.

💡

If the phone starts to overheat (temperature above 45°C), take a break for 10 minutes. Overheating above 50°C can cause trottling (automatic performance decline).

3.Use of camera functions: 4K-video and photo shoot

Redmi's camera modules are some of the most energy-intensive components, and recording 4K@60fps or flash-shot footage drains the battery by 15-20% per hour, and Night Mode, which uses multiple CPU cores to process the images, is particularly effective.

Instructions for maximum discharge:

• 🎥 Start recording the video in 4K with stabilization enabled (Camera settings) → Permission → 4K).
• 💡 Turn on the flash in Always mode.
• 🔄 Activate. HDR and AI-improvement.
• 📸 Take serial pictures (press the down button).

For models with 108 MP cameras (like the Redmi Note 11 Pro+), shooting at maximum resolution is even more effective, and you can also use Pro Mode with manual settings, which forces the processor to constantly process data from the sensor.

⚠️ Attention: Long recording 4K-Video (over 30 minutes) can cause the camera to overheat. Some Redmi models have protection triggered and the recording automatically stops.

4.Technical tricks: disabling MIUI optimizations

MIUI by default limits the background activity of applications to save charge. Disabling these optimizations will discharge the battery by 30-50% faster, but after the process is completed, it is recommended to return the settings to their original state.

Steps to disable optimizations:

1. Go to Settings. → Annexes → Application management → Three points (⋮) → Special access → Optimizing the battery.
2. Select All Apps and disable optimization for YouTube, Chrome, Google Maps and other power-hungry programs.
3. Return to Settings → Battery → Battery Mode and select Performance.
4. Turn off the Adaptive Battery and Background Activity in the Settings → Battery → More.

You can also use the developer mode:

• Activate it by pressing the MIUI version 7 times in Settings → About phone.
• Go to Settings → Additional → For developers.
• Turn on Do Not Turn Off the Screen and Background Limit Process (set No Limits).

5. Discharge via USB (reverse charging)

If your Redmi supports Reverse Charging, you can discharge it by connecting another device, which is suitable for models with USB-C and OTG, such as:

• Redmi Note 11 Pro+
• POCO F3/F4
• Redmi K40/K50

How it works:

1. Connect another device to the phone (for example, TWS-headphones or power bank through USB-C cable.
2. In the notification curtain, the option Reverse charging will appear - activate it.
3. The phone will start to give off energy, discharging at a rate of 5-10% per hour.

To speed up the process, you can simultaneously run an energy-intensive application (such as a game) and turn on the Hot Spot, but note that recharging increases battery wear 10-15% faster than standard use.

6.Discharge through performance tests

Special benchmarks (AnTuTu, Geekbench, 3DMark) create maximum load on the CPU/GPU, draining the battery in 1.5-2 hours, a method often used for stress tests, but it is also suitable for rapid discharge.

Step-by-step:

1. Install AnTuTu Benchmark or 3DMark from Google Play.
2. Run the stress test (in AnTuTu) or the Wild Life Stress Test (in 3DMark).
3. Set the screen brightness to 100% and turn off Autoturn.
4. Repeat the tests in a cycle until the charge reaches 5-10%.

Advantages of the method:

• ⚡ Controlled load (no risk of overheating as in games).
• 📊 Accurate data on battery status and performance.
• 🔄 You can interrupt the process at any time.

⚠️ Warning: After the tests are complete, restart your phone. Prolonged work under load can cause lags in the air. MIUI chipset overheating.

7. Alternative methods: from Bluetooth to AR-game

If standard methods are not available (e.g. no games or the camera is broken), alternative energy-consuming features can be used:

• 🎧 Bluetooth Audio: Connect your headphones and play music at maximum volume via Spotify or YouTube Music.
• 🌍 AR-Applications: Games with augmented reality (Pokémon GO, Harry Potter: Wizards Unite is a camera player, GPS gyroscope.
• 📡 Network Search: Enable Airplane Mode, then manually activate 4G Wi-Fi – Constant search for a signal drains the battery.
• 🔄 Cyclical Reboot: Reboot your phone every 5 minutes (hold power) + Volume upwards. This prevents the optimization of background consumption.

For models with AMOLED-screens (Redmi) K50, POCO F4) white noise is effective: open the white image to the full screen and set the maximum brightness. AMOLED Consume more energy when displaying white.

What NOT to do in the discharge

Some "tip" from the Internet can damage your battery or phone.

• 🔥 Battery heating: Putting your phone on a battery, in a microwave or under the sun will cause the lithium-ion battery to blister or ignite.
• ⚡ Short circuit: Closing the battery contacts with metal objects will knock it out instantly.
• 🔌 Using faulty charges: Connecting to a broken power bank or power supply with the wrong voltage can burn the power controller.
• 📉 Deep discharge to 0%: Shutting down your phone completely without immediate charge reduces battery capacity.

If you need to discharge your phone to replace your battery, you need to charge 5 to 10%, and the full discharge is only required when calibrated (and not on all models).

💡

Safe discharge is discharge without overheating and deep discharge, optimal range: from 100% to 5% followed by immediate charging.
