Stop Apps from Running at Boot on Android - Guide

Optimizing Android Startup Performance
Maintaining a streamlined list of both startup and currently running applications is crucial for optimal performance on the Android operating system. But what methods can be employed to curtail an application-intensive startup process?
Addressing Application Bloat
A large number of applications launching at boot can significantly slow down device responsiveness. Identifying and managing these applications is key to a smoother user experience.
This discussion originates from a query posed to Android Enthusiasts, a dedicated segment within Stack Exchange – a collaborative network of question and answer websites.
The Importance of a Lean App List
A concise selection of applications, both those that launch automatically and those actively running, directly impacts Android's efficiency. Reducing this load can lead to faster boot times and improved overall system performance.
The initial question, brought forth by a member of the Android Enthusiasts community, explores strategies for limiting the number of applications that initiate during the startup sequence.
Stack Exchange as a Resource
The insights shared are sourced from Stack Exchange, a platform renowned for its community-based knowledge sharing and problem-solving capabilities.
Android Enthusiasts, as a specialized branch of Stack Exchange, provides a focused environment for discussing Android-specific challenges and solutions.
Startup applications and background processes can consume valuable system resources. Therefore, careful management is essential.
Understanding how to control application startup behavior is a fundamental aspect of Android optimization.
Addressing Android Startup and Background Processes
An Android Enthusiast reader, Scott Severance, has raised a common concern regarding the management of applications and services that initiate during device startup.
Specifically, he asks how to prevent unwanted applications and services from running in the background upon boot, and how to ensure applications fully exit when navigating from them using the Home button.
This article will explore methods for controlling these processes and discuss whether halting them consistently represents the optimal approach.
Understanding Android Startup Behavior
When an Android device is powered on, numerous applications and services may automatically launch and operate in the background.
These processes can consume system resources, potentially impacting performance and battery life.
Users often desire greater control over which applications are initiated during startup to optimize their device's efficiency.
Managing Background Applications
The behavior of applications when minimized using the Home button is also a frequent point of inquiry.
Typically, applications do not fully terminate but rather enter a paused state, remaining active in the background.
This allows for quick resumption of the application, but can contribute to resource usage.
Methods for Stopping Applications
Several techniques can be employed to prevent applications from running at startup or to force their termination.
- Disabling Startup Applications: Many devices allow users to disable applications from automatically launching during boot through the settings menu.
- Force Stopping Applications: Within the settings, a "Force Stop" option can be utilized to immediately terminate a running application.
- Utilizing Task Managers: Third-party task manager applications can provide more granular control over background processes.
Efficiency Considerations
While stopping applications may seem beneficial, it's important to consider the potential drawbacks.
Android is designed to manage applications efficiently, and frequently terminating processes can actually increase resource consumption.
The system may need to relaunch applications more often, consuming more battery and processing power than allowing them to remain in a paused state.
Optimizing Android Performance
A balanced approach is often the most effective strategy.
Instead of aggressively stopping all background applications, focus on identifying and disabling those that are demonstrably impacting performance or battery life.
Regularly reviewing app permissions and uninstalling unused applications can also contribute to a smoother and more efficient Android experience.
Understanding Android App Behavior
Matthew Read, a SuperUser contributor, provides a comprehensive analysis addressing concerns about Android app startup and background processes, suggesting that the impact may be less significant than some believe.
Initial Considerations
It's important to have a clear understanding of how Android functions and what actually occurs when an application runs or operates in the background. Further information can be found in discussions about the necessity of task manager applications.
When you switch between applications or return to the home screen, most apps – those launched manually – have their current Activity placed in the background. These Activities consume some memory, allowing for a seamless return to the app and continuation of your previous actions. Importantly, Activities generally cannot execute computations while in the background, meaning they don't utilize CPU or battery resources. Therefore, if battery life or performance is a concern, these backgrounded Activities are typically not an issue.
Android also manages memory efficiently, automatically terminating apps and freeing up resources when the system is running low. You don't need to manually intervene in this process.
Background Services: A Different Story
If an app in the background is running a service, the situation can differ. Well-designed services primarily remain in a sleeping state, waking up periodically to check for updates, such as new social media notifications. However, poorly designed services may operate more frequently or perform unnecessary synchronization tasks, potentially impacting battery life and data usage.
If you identify a problematic service, the solutions outlined below may be helpful.
Potential Solutions
If you are determined to prevent an app from running, several methods can be employed.
Uninstalling the Application
If an app exhibits undesirable behavior, such as running in the background at startup, uninstalling it is often the most straightforward solution. This completely resolves the issue. Root access allows for the removal of system apps, but caution is advised; only uninstall carrier bloatware and avoid deleting critical system applications.
However, if you wish to continue using the app, explore the following options.
Contacting the Developer
Many Android services are poorly optimized, continuing to run when a simple interval check using Android's AlarmManager would suffice. Addressing these issues requires developer intervention. Contacting the developer with your concerns allows them to fix the app, resulting in a positive outcome for all involved.
Manually Terminating Apps
Many applications can be closed completely by navigating back from them rather than using the Home button.
On Ice Cream Sandwich or Jelly Bean, you can access Settings, select Applications, and manually shut down apps by switching to the running apps tab. Alternatively, use the Recent Applications button and swipe apps off the screen to close them. Older Android versions may include a built-in Task Manager, or you can download a third-party task manager app. For managing services, navigate to:
Settings -> Applications -> Services.
WARNING: Avoid using automatic task killers. These run in the background – precisely what you want to avoid – and repeatedly kill apps, often worsening performance. Apps consume more resources during startup than when idle, and frequently restarted services waste battery. Apps receiving system events (Intents) will also be killed repeatedly, negating their functionality.
An exception may be automatic tasks triggered by specific user actions. These simply streamline manual task management. Apps like Tasker or Llama can be used to terminate activities when switching apps, preventing them from remaining in the background. Here's an example using Llama:
Create a new Event. Add the Active App condition, setting the status to App stopped or in background. Select the target app. Next, add an Action. Choose Kill Application (root privileges) and select the app again.
Llama will then terminate the app whenever you leave it.
Modifying Autostarts and Intents
Some applications start automatically in response to Intents (system events). Using an app like Permissions Denied, you can control which permissions apps request, limiting the events they can receive. Alternatively, Autostarts allows you to directly edit which Intents are sent to which apps. Both solutions require root access.
Additional options include:
- Autorun Manager
- Gemini App Manager
(Autostarts is free and open-source software, also available from f-droid.)
WARNING: Altering these settings can cause apps to malfunction or disable desired functionality. Proceed with caution, especially with system apps.
Freezing Applications
Apps like Titanium Backup or App Quarantine can completely freeze apps, preventing them from running until unfrozen.
WARNING: Do not freeze critical system apps, as this may prevent your device from booting.
Hibernating Applications
Greenify (requires Android 4.0+ and ROOT privilege) employs a different approach called "Hibernation."
You can safely hibernate any non-system app to prevent stealthy background activity (via services, receivers, alarms, etc.), effectively freezing it while maintaining full functionality when explicitly launched, without needing to unfreeze it first.
WARNING: Avoid hibernating alarm clock apps, instant messaging apps, and other apps relying on background mechanisms (timers, system events, "push" notifications) for core functionality.
Concluding Thoughts
Android is designed to manage applications automatically. In most cases, manual intervention is unnecessary. When issues arise, the simplest solution – uninstalling the app – is often the most effective. Other solutions are workarounds for Android's intended behavior. Official support for managing services may be added in the future, but until then, exercise caution.
