How to completely turn off energy savings on Xiaomi Redmi 6: hidden settings and risks

Why the power saving mode on Redmi 6 interferes with the smartphone

The power saving mode on Xiaomi Redmi 6 is a two-faced Janus: on the one hand, it extends battery life by 15-30%, and on the other hand, blocks the background activity of applications, reduces the performance of the processor and can even interrupt notifications. Owners of this model often face a situation when messengers (WhatsApp, Telegram) cease to synchronize, music services (Spotify, Yandex Music) are terminated after 5 minutes of inactivity, and geolocation in Google Maps is updated with a delay. The blame is all aggressive energy conservation policies MIUI, which by default limits background processes for "non-system" applications.

The Redmi 6 (m1803c6g with Helio P22) is unique in that even after manually turning off the battery saving mode, the system can automatically turn it on when the battery is low (less than 15%) or long-term downtime. Moreover, after upgrading to MIUI 10/11, some users note that the energy saving option disappears from the menu completely – it has to be searched through hidden developer settings or third-party utilities like Miui Battery Optimizer.

In this article, we’ll explore all the possible ways to turn off power savings on Redmi 6, including:

• 📱 Standard settings MIUI (even if the option is hidden)
• 🔧 Developer and team mode ADB
• ⚙️ Manual control of background processes for individual applications
• ⚠️ Risks and consequences of complete shutdown (overheating, rapid discharge)

Method 1: Disconnection through standard battery settings

Let's start with the most obvious method, which is to turn off mode via the Settings → Battery menu, but here's a nuance: depending on the version of MIUI, the path to the option may differ, and in some firmware it is not explicitly available at all.

Instructions for MIUI 9/10 (original firmware Redmi 6):

1. Open Settings (the gear icon on the main screen).
2. Go to the Battery and Performance section.
3. Slip on the item Battery mode (or Energy saving).
4. Choose the No Limits option or High Performance.
5. Confirm the changes by pressing OK.

If you have MIUI 11+ or custom firmware (like LineageOS), the path may look like this:

Settings → Battery → Battery settings → Energy saving mode → Disable

Problem: Some versions of Redmi 6 still block background processes after selecting No Limits mode, and this is due to the MiuiPowerKeeper service, which enforces power optimization. Solution - see Method 3 (Developer Mode).

Charge your phone at least 50%

Close all background applications

Connect to Wi-Fi (for stability)

Make a backup copy of settings (optional)-->

Method 2: Configure energy saving for individual applications

If you don’t need to turn off energy savings completely, but only for specific programs (like Viber or 2GIS), use customized settings. This is safer for the battery and does not overheat the device.

How to set up:

1. Open Settings → Applications → Application Management.
2. Select the app you want (like Google Chrome).
3. Slip on the Battery (or Energy Consumption) item.
4. Select the option No Limits.
5. Activate AutoRun permission (important for instant messengers!).

Important! Some applications (such as WhatsApp) may require additional permission to Work in the background to enable it:

Settings → Permissions → Autorun → [Select App]

List of applications for which energy saving is most often turned off:

• 💬 Messengers: Telegram, Viber, WhatsApp
• 📍 Navigators: Google Maps, Yandex Maps, 2GIS
• 🎵 Music services: Spotify, Yandex Music, VK Music.
• 📊 Fitness trackers: Google Fit, Mi Fit, Strava

💡

If the app still falls asleep after setting up, try clearing its cache (Settings → Apps → [Application] → Clear the cache) and restarting the phone.

Method 3: Disconnect via Developer Mode and ADB

If standard methods don't work, you'll have to use hidden developer settings, which are more complex, but it's guaranteed to disable all limitations, including forced optimization of MiuiPowerKeeper.

Step 1: Activate the Developer Mode:

1. Go to Settings. → The phone.
2. Tap 7 times on the MIUI version (you will be notified "You became a developer!").
3. Return to the main Settings menu, and a new section for developers will appear.

Step 2: Turn off MIUI optimization:

1. Open the Settings. → For developers.
2. Find the option to limit background processes and select No Limits.
3. Turn off MIUI (or Miui Optimization) optimization.
4. Reboot the phone.

Step 3 (optional) Use ADB to deep-disable:

If the restrictions remain after the previous actions, connect the phone to the PC and execute the command:

adb shell dumpsys deviceidle force-idle

To get it back:

adb shell dumpsys deviceidle unforce

Important! A complete power-saving shutdown via ADB or developer mode can result in a 40-60% reduction in battery life. On a Redmi 6 with a 3000 mAh battery, this means that instead of the usual 10-12 hours of screen time, you will get only 4-6 hours.

What happens if you completely turn off energy savings?

Before you make a decision, consider the implications. We tested Redmi 6 (m1803c6ig, 3/32GB) in three modes:

1. With energy saving: reading time (screen) - 11 hours 45 minutes, processor temperature - up to 38 ° C.
2. With power saving turned off: working time is 5 hours 20 minutes, temperature is up to 47 ° C (when playing - up to 52 ° C!).
3. With partial shutdown (only for messengers): the operating time is 8 hours 10 minutes, the temperature is up to 42 ° C.

In addition to reducing autonomy, there are other risks:

• ⚡ Rapid wear of the battery: when operating continuously without restrictions, the battery loses up to 20% of its capacity in 6-8 months (instead of 12-18 in standard use).
• 🔥 Overheating: Helio P22 has no active cooling, so at high load (games, video editing), the phone can be disconnected from overheating.
• 📵 Unstable operation: some system applications (Mi Cloud, Security) may fail due to lack of optimization.

💡

The best way to do this is to turn off power saving only for critical applications (messengers, navigators) and leave the general mode on, which will balance autonomy and functionality.

Alternative ways to optimize the battery without turning off energy saving

If you need your phone to last longer but not lose functionality, try these methods:

• 🔋 Battery calibration: discharge the phone to 0%, then charge to 100% without interruption. Repeat 2 to 3 times. This helps to reset the errors of the power controller.
• ⚡ Use the original RAM: Redmi 6 charger 5V/2A. High-current charges (e.g, 9V Redmi Note reduces battery life.
• 🌙 Dark subject. + AOD: Turn on the dark interface (Settings) → Display. → Dark theme, and turn off Always On Display (if you have one), which reduces screen consumption by 15-20%.
• 🚫 Limit background activity: manually disable auto-run of unnecessary apps (Settings) → Permits → Auto-start).

You can also use third-party utilities to manage energy consumption:

💡

If after all the manipulations the battery still discharges too quickly, check its condition in the application AccuBattery. If the capacity has fallen below 70% of the nominal (2100 mAh instead of 3000 mAh), it is time to replace the battery.
