10 Reasons Why Your Phone’s Battery is Draining Fast
Here are some of the reasons why your Android or iPhone battery is draining so fast. Sometimes a phone’s battery drains all of a sudden and most of the time, it is not a big problem unless it is happening again and again. Once you found the reason for the fast battery draining, you will also be able to fix it.
1. Brightness Settings
One of the most common reasons for battery drain is having your phone’s brightness set too high. When your screen is brighter, it consumes more battery power. Try turning down the brightness of your screen to save battery life. You can also use the auto-brightness feature that adjusts the brightness according to the ambient light around you.
After lowering the brightness down, you will see an improvement in your battery backup. But if the phone’s battery still draining rapidly, you need to look further to find out the problem.
2. Background Apps
Running too many apps in the background can also be a big reason for the fast battery drain. Each app running in the background consumes processor, RAM, and memory which requires constant power. This ultimately means more battery draining. Therefore, close any apps that you’re not using to save on battery power. You can do this by swiping up or down from the bottom of your screen and swiping the apps up or off the screen. Every phone has its own interface for accessing background apps.
3. Push Notifications
Push notifications from apps can also drain your battery quickly. When an app sends you a notification, your phone wakes up from sleep mode, consuming battery power. Turn off notifications for apps that you don’t need alerts from. Go to your phone’s settings, find the apps you don’t need notifications from, and turn off the notifications.

Some push notifications flash the ‘Sales’ banner with the timer which keeps on using the phone’s battery. Disabling notifications from such apps will definitely help you in keeping your battery healthy.

4. Wi-Fi and Bluetooth
Both Wi-Fi and Bluetooth can drain your battery quickly, especially if you’re not using them. Your phone continuously searches for Wi-Fi and Bluetooth connections, consuming battery power. If you’re not using them, turn them off. Go to your phone’s settings, find the Wi-Fi or Bluetooth option, and turn them off.

Keeping Wifi and Bluetooth turned on not only drains the battery but is also harmful. Anyone can connect to your device and can inject malicious codes via Bluetooth. So, keep your phone’s wifi and Bluetooth off when not in use.
5. Location Services

Using location services constantly can also be a battery killer. When an app uses your location, it keeps your phone’s GPS on, which consumes a lot of battery power. It constantly requires connection directly with GPS satellites which is definitely a power-eating task. Try turning off location services or only use them when necessary. Go to your phone’s settings, find the location services option, and turn it off or choose apps that can use it.
6. Heavy Usage

If you’re using your phone heavily, such as playing graphic intensive games on ultra settings, watching movies on Netflix, and Prime Video, recording 4K videos, or scrolling Instagram all day long. It’s quite obvious that it will consume a lot of battery. Try limiting your heavy usage or plug your phone into a charger while using it to extend battery life. However, it is not suggested to use the phone while charging but if it is part of your work or you are in an emergency, you can do it but don’t use the phone while charging for a longer duration.

7. Outdated Operating System
If you’re using an older version of your phone’s operating system, it may not be optimized for battery performance. For example, if you are still using Android 7.0 when Android 12 is already out, it is quite obvious that newly updated apps are optimized for Android 12, not for Android 7. The same thing goes for iOS. And this is the reason why your phone’s battery is dying so fast.
Update your phone’s software to the latest version to improve battery life. Go to your phone’s settings, find the software update option, and update your phone. If you are using an older smartphone, the manufacturer might not push the latest software update for your phone and this is the time to update to a new smartphone.
8. Battery Health
The battery health of your phone may also be a reason for the fast battery drain. Over time, all batteries degrade and lose their capacity to hold a charge. If your phone’s battery health is less than 80%, it’s time to replace the battery.
The battery’s health depends on its user. If you are overcharging your phone’s battery, heavily use the phone, charge the phone overnight, let your phone dies at 0% battery, there is a high chance that your phone’s battery health will degrade fast.
9. Using High Resolution
Smartphones these days come with the high-resolution display but they also provide you the option to lower the screen resolution. For example, Samsung Galaxy S23 comes with a 3088 x 1440p resolution but it also allows you to set a lower resolution than this. Using high resolution will definitely consume more battery than lower resolution.
When it comes to the screen resolution on a smartphone, it is always suggested to find the balance between battery optimization and good user experience.

10. Battery-Draining Apps
Some apps are notorious for draining battery power, even when you’re not using them. Facebook, Snapchat, and Google Maps are some examples of battery-draining apps. Uninstall or limit the use of these apps to extend your phone’s battery life. Additionally, you can use battery-saving modes on your phone to restrict the background activity of such apps. Simply go to your phone’s settings, find the battery-saver option, and enable it. This will limit the activity of these apps and help extend your phone’s battery life.
Fix Phone’s Battery Draining Issue: Wrap Up
If you’re constantly wondering why your phone’s battery is draining so fast, the above 10 reasons may provide some answers. By making a few simple adjustments to your phone’s settings, you can extend your battery life and avoid the frustration of a dead battery. Try adjusting your brightness settings, turning off background apps and notifications, disabling location services, and limiting heavy usage. If none of these tips work, it may be time to replace your battery or seek professional help. Remember, by taking care of your phone’s battery, you can enjoy its many features and benefits for a longer period of time.
