How to completely remove optimization on Android: from battery to system limitations

Modern smartphones on Android actively use a variety of optimization mechanisms - from limiting background application activity to aggressive battery management. These features are designed to extend battery life and improve performance, but they often get in the way: apps don't receive notifications, games lag, and background processes suddenly stop. If you are faced with the fact that optimization interferes with the normal operation of the device, you can disable it - completely or selectively.

In this article we will look at all the ways to remove optimization on Android - from standard settings to hidden developer options and commands ADB. You'll learn how to disable battery optimization for individual apps, how to remove performance restrictions, and what to do if your system automatically resets after an update. It is important to understand that completely disabling optimization can reduce battery life and increase the heating of the device - but in some cases this is a necessary measure.

Why does Android optimize the device?

Optimization for Android is a set of measures that the operating system uses to:

• 🔋 Saving battery power - limit background activity, reducing the processor clock frequency, disabling unused modules (GPS, Wi-Fi scanning).
• ⚡ Increasing performance —prioritizing resources for active applications, clearing the cache, managing RAM.
• 🛡️ Overheating protection — throttling (artificial slowdown) of the processor at high temperatures.
• 📱 Extending the life of the device —reducing the load on the battery and chipset.

Starting from Android 6.0 Marshmallow, Google has implemented a mechanism Doze Mode (sleep mode) that aggressively limits background processes when the device is not in use. In Android 8.0 Oreo there appeared restrictions on background activity for applications, and in Android 9.0 Pie — Adaptive batterywhich analyzes the user's habits and blocks rarely used applications. Smartphone manufacturers (Samsung, Xiaomi, Huawei) add their own layers of optimization, which often leads to conflicts.

The problem is that these mechanisms do not always work correctly. For example, messengers (Telegram, WhatsApp) may not receive notifications, fitness trackers (Google Fit, Strava) may lose activity data, and games may slow down due to artificial performance limitations. If you notice such symptoms, over-optimization is most likely to blame.

How to disable battery optimization for individual applications

The easiest way to return applications to normal operation is to exclude them from the list of optimized ones. This will not disable all saving mechanisms, but will allow critical apps to run in the background without restrictions.

Instructions for pure Android (for example, Google Pixel):

1. Open Settings → Applications and notifications → All applications.
2. Select the desired application (for example, Telegram).
3. Tap on Battery → Battery optimization.
4. In the drop-down menu, select Do not optimize.

On smartphones Samsung the path is different:

1. Go to Settings → Device maintenance → Battery.
2. Click on the three dots in the upper right corner and select Settings.
3. Tap Sleep mode for applications and add the desired apps to the exclusion list.

For devices Xiaomi, Redmi i POCO your approach:

1. Open Settings → Battery and performance → Battery management.
2. Select Selecting applications and mark those for which you want to disable optimization.
3. Turn on the switch No restrictions.

If after these steps the application still behaves incorrectly, the manufacturer may have blocked manual optimization control. In this case, it will help ADB (we'll talk about it below).

⚠️ Attention: On some devices (Huawei, Honor), after updating the firmware, optimization settings are reset. Check exceptions after each update.

Disabling adaptive battery and background activity

Adaptive battery is a function that analyzes your habits and limits resources for rarely used applications. It is useful for saving battery, but it often makes mistakes, blocking important processes. You can disable it like this:

On pure Android:

1. Go to Settings → Battery → Adaptive settings.
2. Disable the switches Adaptive battery and Limit background activity.

On Samsung:

1. Open Settings → Device maintenance → Battery.
2. Tap on the three dots → Settings → Adaptive battery.
3. Disable the function.

On Xiaomi/Redmi/POCO:

1. Go to Settings → Battery and performance → Battery settings.
2. Disable Adaptive battery i Restriction of running in the background.

After disabling the adaptive battery, applications will be allowed to run in the background without restrictions, but battery life will be reduced by 10–25% (depending on the model).

Using ADB to deeply disable optimization

If the standard settings do not help, you will have to connect to the device via ADB (Android Debug Bridge) (This method allows you to disable optimization at the system level, but requires a computer and basic skills in working with the command line). line.

What you will need:

• 💻 Computer with drivers installed Android i ADB.
• 🔌 USB cable (preferably original).
• 📱 Debugging enabled via USB on a smartphone (Settings → About phone → Build number (tap 7 times) → Developer settings → USB debugging).

Step-by-step guide:

1. Connect your smartphone to the computer and confirm permission to debug.
2. Open the command line (cmd on Windows or Terminal on macOS/Linux).
3. Enter the command to check connections:

   adb devices

   Wait for the device serial number to appear.

4. To disable optimization for a specific application (for example, Telegram), do:

   adb shell dumpsys deviceidle whitelist +org.telegram.messenger

5. To completely disable the mode Doze (not recommended!):

   adb shell dumpsys deviceidle disable

6. To disable the adaptive battery:

   adb shell settings put global adaptive_battery_management_enabled 0

After rebooting the device, all changes made via ADB will be reset. To make them permanent, you need to create a script that will be executed when the system starts.

⚠️ Attention: Some manufacturers (for example, Huawei) block commands ADBrelated to optimization. In this case, only getting root access or custom firmware will help.

Disabling performance optimization (throtting)

Many smartphones artificially limit processor performance to prevent overheating or extend battery life. This is noticeable in games, when rendering videos or running heavy applications. You can disable throttling through developer settings:

How to enable developer mode:

1. Go to Settings → About phone.
2. Find item Build number and tap on it 7 times.
3. Enter the PIN code or pattern if required.

Now open Settings → System → For Developers and find the following parameters:

• 🔧 Disable absolute frequency limit (if available) - removes restrictions on the maximum processor clock frequency.
• 🔥 Disable thermal zone throttling - prevents performance degradation when heated.
• 🎮 Force the use of 4x MSAA —improves graphics in games (but increases load).
• ⚡ Do not turn off the screen during charging —useful for long tasks.

On devices Samsung you can additionally disable Game Optimizing Service (GOS) a service that limits performance in games. To do this:

1. Open Settings → Applications.
2. Tap on three dots → Show system applications.
3. Find Game Optimizing Service and disable it.

Reset optimization after firmware update

One ​​of the most common problems is automatically reset optimization settings after update Android. Manufacturers often return all settings to factory settings to “improve the user experience.” To avoid this, you can:

• 📝 Create a backup copy of the settings using ADB:

  adb pull /data/system/batterystats.bin batterystats_backup.bin

  After updating, restore the file:

  adb push batterystats_backup.bin /data/system/batterystats.bin
  adb shell chmod 660 /data/system/batterystats.bin

• 🔄 Use automation (for example, Tasker or MacroDroid) to reapply the settings after a reboot.
• 🚫 Disable automatic firmware update in the system settings (if this is critical).

On some devices (Xiaomi, Realme), disabling the function helps MIUI Optimization (only for firmware with an unlocked bootloader). To do this, through ADB execute:

adb shell settings put global miui_optimization 0

⚠️ Attention: Backing up system files may disrupt the operation of the device if the version Android has changed. Before restoring, check compatibility.

What to do if optimization cannot be disabled?

Some manufacturers (especially Huawei, Honor, Oppo) are so aggressive in blocking the ability to disable optimization that standard methods do not work. In this case, there are several options left:

• 🔓 Get root access and manually edit system files (for example, /system/build.prop). This is risky and voids the guarantee.
• 📱 Install custom firmware (for example, LineageOS), where there is no aggressive optimization. Requires unlocking the bootloader.
• 🔄 Use alternative launchers (for example, Nova Launcher), which allows you to bypass some restrictions.
• ⚙️ Use workarounds —for example, run problematic applications through Island (sandbox) or Shelter.

If you are not ready for such drastic measures, try the following workarounds:

• Add the application to autorun exceptions (on Xiaomi: Settings → Permissions → Autorun).
• Enable it high priority notifications.
• Launch the application manually before important events (for example, before training for a fitness tracker).

On devices Huawei there is a hidden menu for managing optimization. To open it:

1. Open the application Telephone.
2. Enter the code: ##2846579##.
3. Go to ProjectMenu → Background Settings and disable optimization for the desired applications.
