Why Is My Phone Battery Dying So Fast All of a Sudden

Have you ever noticed that your phone battery seems to be draining faster than usual? If you’re wondering why your phone battery is suddenly dying so fast, there could be a number of reasons. In this article, we’ll explore some of the most common causes of sudden battery drain and provide tips for troubleshooting the issue. Whether you’re using an iPhone or an Android device, these solutions should help you extend your phone’s battery life and get back to using your device without worrying about running out of power.

There are several reasons why your phone battery might be dying so fast:

  1. Battery age: Over time, all phone batteries lose their ability to hold a charge, which can result in shorter battery life.
  2. Background apps: Apps running in the background can drain your battery even if you’re not actively using them. Try closing apps you’re not using and limiting the number of apps running in the background.
  3. Brightness: Keeping your phone’s screen brightness turned up can also drain your battery quickly. Try turning the brightness down or using auto-brightness to help conserve battery life.
  4. Location services: GPS and other location services can also drain your battery quickly. Try turning off location services for apps that don’t need it, or turn off location services altogether when you’re not using them.
  5. Push notifications: Apps that constantly send push notifications can also drain your battery. Try turning off push notifications for apps that you don’t need them for.
  6. Network connection: Poor network connection or weak Wi-Fi signals can also drain your battery, as your phone will constantly be searching for a stronger signal. Try turning off Wi-Fi or cellular data when you’re not using them.
  7. Phone settings: Certain phone settings, such as vibration or auto-lock, can also drain your battery. Try adjusting these settings to see if it helps improve battery life.

If none of these solutions help, it may be time to consider replacing your phone battery or upgrading to a newer phone with a longer battery life.

This article focuses on the most common reasons and how to fix phone battery draining fast. The most common reasons that cause your phone to drain fast include:

1: The Level of Screen Brightness You Have Selected Is Too High

If you’re using your phone outside, turning up the brightness all the way might seem like a good idea, but it’s very draining on the battery. In addition, if you use the light mode of your phone while keeping the brightness at its highest, your battery will drain even faster. Reduce the brightness on your screen as much as possible to eke out every drop of juice from your battery.


You may also change the brightness settings on your phone so that it adapts to the various lighting conditions outside. As a result, it may adapt to its surroundings by darkening in dim light and lightening in strong sunlight. To accomplish this, you will first need to access the settings menu on your phone and then navigate to the Display & Brightness section.

You can change the brightness setting on your phone to one that is customizable, which will help you save a significant amount of battery life over time.

However, a screen with less brightness isn’t always the best option, specifically if you have trouble seeing clearly. So, in addition to turning down the brightness of your screen, what other options do you have?

Alternatively, you might adjust the display mode of your commonly used apps to dark mode and the display mode of your device’s general display. That won’t completely black out your phone’s display, but it will change the white backgrounds of your phone’s menus and apps to black. You wouldn’t believe how much battery life this saves.

2: Running Background Apps

The programs that run in the background continue to work even when you are not actively using them. Some examples are apps like virtual private networks (VPN), virus scanners, health trackers, and calendars. While it may be helpful, the apps control various parts of your smartphone without your intervention. However, this results in a significant drain on your phone’s battery.

Likely, you do not require most of these applications to operate in the background. So, how do you disable apps that run in the background?

Follow the steps above to access your settings and select either Battery or Device Care for Android or iPhone, respectively. After that, you should notice an option to optimize your battery life, which, when activated, will force any extra programs running in the background to stop. It is in your best interest to give this some thought because it may help you preserve more of your battery life.

3: Alerts and Push Notifications

When you download and install a new application on your mobile device, there is a reasonable probability that you will also activate the notification settings associated with that app immediately. However, it is unnecessary to have alerts sent to you from every app that you have installed. Doing so may hurt the time that your phone’s battery will last.


You can reduce the power loss caused by particular apps by turning off their notifications.

To accomplish this, access the Notifications section of your phone’s settings by navigating to the Settings menu on your device. All your phone’s installed apps’ notification preferences will be shown here for your perusal.

You may modify the app’s notification settings by toggling them on and off or by touching the app icon to access more granular controls. For instance, you could want to be notified when you receive a new Facebook message but not when you receive a new Like or Follow.

4: GPS Tracking Applications

Many apps can monitor your location. The entire suite of apps, including Google Maps and retail apps. And while you may believe these applications only track your whereabouts when you’re actively using them, that’s not necessarily the case. This continuous monitoring of your location consumes energy, reducing the time the battery in your phone lasts.


Turning off your device’s location services entirely is the quickest and easiest option to disable tracking based on location. You may find this option in the dropdown menu on your phone. You can also keep your finger pressed on the location icon in the dropdown menu to access your phone’s location settings, as illustrated in the following example.

However, you can stop location tracking for particular apps by going to your device’s “Permissions” section of the settings for each app. That is useful if you want some apps, such as a safety or navigation app, to continue tracking your whereabouts. Though it may take some time, this allows you to decide which apps have access to your location and which do not.

5: Connected Around the Clock

If you want to be connected at all times, whether day or night, it’s probably best to keep your data or Wi-Fi turned on. It may seem like an obvious choice. However, this might severely drain your phone’s battery because you will receive background updates, notifications, and other information, even though you may not require it.


Turning off your Wi-Fi network is a good idea when sleeping in bed. You may easily activate airplane mode on your phone. If you are concerned about missing an important phone call, you can use the dropdown menu on your phone to turn off your data and Wi-Fi connection so that you can continue to receive phone calls. Remember that putting your phone into the “Do Not Disturb” mode will not turn off either the Wi-Fi or the data on your device.

6: Your Battery is Probably Old

Your phone’s battery life may be affected by factors other than software or configuration. Phones, like everything else, eventually become obsolete, and as time passes, the quality of your phone’s battery will decline. Your phone’s battery may drain quickly after two to three years – depending on the model since it can no longer reach its maximum capacity.

Occasionally, but not always, your phone will warn you when it notices a decline in battery performance. Shorter battery life is the most prevalent indication of a failing battery without warning.


The most basic solution is to get new batteries. That may be a simpler and less expensive option than getting a new phone to solve the problem of a rapidly depleting battery. The cost of a new battery will differ based on the model of your phone.

Of course, you could also get a new phone. It’s possible that it’s not simply the battery that’s lost its charge and that replacing it would be the most practical and cost-effective choice. Repairing a modern smartphone is not cheap, so if yours has several broken parts and is getting old in years, you may want to consider upgrading.

What Drains Phone Battery the Most?

Phone screen. Since the advent of modern smartphones, the screen has been the primary culprit in rapidly depleting battery life. The size, resolution, and aesthetic quality of displays continue to improve. Dual-screen smartphones and even larger folding phones are already available. These upgrades enhance the mobile experience but come at the expense of increased battery drain.
