What Causes Battery to Drain : Insidious Power-Thieves

What Causes Battery to Drain

The main causes of battery drain are excessive usage and background apps running on your device. When you use your phone or other electronic devices for extended periods, it puts a strain on the battery and ultimately drains it.

Additionally, background apps consume power even when you are not actively using them, contributing to the battery drain. To optimize battery usage, it is advisable to limit usage and close unnecessary apps in the background. Regularly updating your device’s software and ensuring proper charging habits can also help extend battery life.

Understanding the factors that cause battery drain can help you better manage your device’s power consumption.

Common Culprits

One of the common culprits behind battery drainage is leaving apps running in the background. Other causes can include screen brightness, GPS, and Wi-Fi. It’s essential to monitor these factors to ensure optimal battery life for your devices.

There’s nothing worse than finding yourself with a drained battery in a crucial moment. So, what could be behind your device’s sudden power drain? Let’s explore the common culprits that could be responsible for depleting your battery life:

Background Apps

One of the major factors contributing to battery drain is the presence of background apps. These are the apps that continue to run even when you’re not actively using them. When multiple apps are operating simultaneously, they consume a significant amount of battery power.

To close these apps on your device, follow these simple steps:

  1. Launch the “Settings” app on your device.
  2. Scroll down and tap on “Apps” or “Applications”.
  3. Select the “Running” or “Active” tab.
  4. Identify the apps that are running in the background and tap on them.
  5. Tap on the “Force Stop” or “Quit” button to close the app completely.
Apps that commonly consume battery in the background
App Possible actions to optimize battery life
Social media apps (Facebook, Instagram, Twitter, etc.) Disable auto-refresh, limit notifications
Instant messaging apps (WhatsApp, Messenger, etc.) Decrease the frequency of chat backups, lower media auto-download settings
Weather apps Disable location services, limit constant updates
Navigation apps (Google Maps, Waze, etc.) Close the app after use, minimize usage of in-app features

Faulty Hardware

Another culprit for battery drain could be faulty hardware components. Damaged batteries, charging ports, or power buttons can cause excessive power consumption and prevent your device from holding a charge for an adequate amount of time.

If you suspect that faulty hardware is the cause of your battery drain, consider these steps:

  • Inspect your battery for any signs of physical damage, such as bulging or leaking.
  • Ensure your charging port is clean and free from debris.
  • Try using a different charging cable and adapter to rule out any issues with the charging accessories.
  • If you have been experiencing any issues with the power button, consult a professional technician to have it repaired or replaced.

By being aware of these common culprits and taking a proactive approach, you can ensure your battery lasts longer, saving you from unexpected moments of power drainage.

Environmental Factors

One of the key factors affecting battery drain is the surrounding environment. Several environmental factors can put a strain on your device’s battery life and cause it to drain faster than usual. Being aware of these factors and how they affect your battery can help you optimize its usage and extend its lifespan. In this article, we will dive into two crucial environmental factors that can significantly impact your battery life: extreme temperatures and high battery drain.

Extreme Temperatures

Extreme temperatures, both hot and cold, can impact your battery performance and contribute to rapid battery drain. Let’s take a closer look at how each temperature extreme affects your device’s battery:

  1. Hot Temperatures: Exposing your device to excessive heat can cause the battery to overheat, leading to reduced battery life and potential long-term damage. Heat accelerates the chemical reactions within the battery, increasing self-discharge and shortening its overall lifespan. Thus, prolonged exposure to hot temperatures, such as leaving your device in direct sunlight or enclosed spaces like a car on a hot day, can weaken the battery and result in faster drain rates.
  2. Cold Temperatures: Similarly, cold temperatures can negatively impact your battery life. In colder environments, the battery’s chemical reactions slow down, reducing its ability to generate power. As a result, your device may experience sudden drops in battery percentage or shutdowns. For instance, if you keep your phone in your pocket outside during winter, the cold temperature can significantly affect its battery performance. Hence, it’s crucial to be mindful of extreme temperatures and their impact on your battery.

High Battery Drain

High battery drain refers to scenarios where your device is consuming more battery power than usual, resulting in quicker battery depletion. Several factors can contribute to high battery drain, including:

  • Background Apps: Some apps continue to run in the background even when you are not actively using them, consuming significant amounts of battery power. Make sure to optimize your app settings, disabling background refresh for apps that don’t require it, to prevent unnecessary battery drain.
  • Screen Brightness: Keeping your device’s screen brightness at high levels can be a major drain on battery life. Reduce the brightness or enable auto-brightness to ensure your screen only uses as much power as necessary.
  • Push Notifications: Constant push notifications from various applications can cause your device to wake up frequently and consume battery power. Consider disabling push notifications for less critical apps or limit them to essential ones only.
  • Location Services: Apps that consistently track your location are known to have a significant impact on battery usage. Manually manage location permissions for apps and only grant them when required.
  • Unoptimized Settings: Certain device settings, such as high data usage, background data, or automatic app updates, can contribute to increased battery drain. Review and adjust these settings based on your preferences and usage patterns.

By understanding the environmental factors that lead to battery drain, such as extreme temperatures and high battery drain scenarios, you can take proactive steps to optimize your device’s battery usage and improve its overall lifespan.

User Habits

User Habits have a significant impact on the lifespan of a battery. Understanding how user behavior influences battery drain is crucial in maintaining optimal performance. Let’s delve into some common user habits that can cause battery drainage.


Overcharging your device can significantly reduce the battery’s overall lifespan. When a device is left connected to the charger beyond 100% capacity, it can lead to increased heat generation and degradation of the battery’s chemical composition.

Heavy Usage Patterns

Heavy Usage Patterns, such as running multiple apps simultaneously, streaming high-definition videos, or engaging in processor-intensive tasks, can expedite battery depletion. The more tasks and applications running in the background, the faster the battery is depleted.
