Why is the Battery on My iPhone Draining So Fast? 

Before we give you the solution to the question, “why is my battery on iPhone draining so fast?” let’s find out the causes: 

  • Display settings and screen timeout. Your screen brightness can really affect your battery life. Also, if it takes too long for your screen to turn on, it can eat up your battery life. You can fix the problem by adjusting the settings. 
  • Apps running in the background. If you have so many apps running in the background, it can also drain your iPhone battery. Furthermore, if you have apps that refresh often, that can also contribute to the battery drainage. 
  • Buggy software. Some apps are buggy and poorly optimized. This can drain your battery life if you have them installed on your iPhone. If your battery drains all of a sudden, it could be an updated app or phone. 
  • Old and degraded batteries. If you’ve been using your iPhone for years, the battery may be degraded, and that can cause it to drain faster. 
  • Push email and app notifications. There’s nothing really wrong with getting notifications, but they can also consume lots of battery power. You can adjust the settings to receive only important notifications. 

How to Fix “Why is My iPhone Battery Draining So Fast.” 

Now, let’s find out how to stop your iPhone from draining faster. Follow and implement the solutions discussed below: 

Solution 1: Check your iPhone Battery Health suggestions

Your iPhone usually recommends particular changes to save your battery life. Just go to the “Settings” app, search for “Battery,” and tap on it. After that, tap on “Battery Health & Charging.” 

You’ll get suggestions on the next screen that can help you improve your battery life. You can tap on each suggestion to go to the settings that need changing. 

Note: If you don’t see the “Battery LIfe Suggestion," it may mean that your iPhone doesn’t have any ways to improve your battery life using the “Settings” app. 

Of course, this doesn’t mean you can’t fix your iPhone’s battery drainage. Keep reading to find other ways to fix the issue.

Solution 2: Check the apps using more battery power

Go to Settings and then tap Battery to see which apps are eating up most of your battery life. The Battery window helps you to see the apps that have used up the most battery life in the last three or four days. 

After you've determined which apps are draining your battery life, you can remove or force-quit them if you're not using them.

Solution 3: Check if your apps are updated recently 

Sometimes, your iPhone’s battery can be suddenly draining because of an app update or your device installed a patch. 

So you can check if there are any apps that have been updated recently.

Click the profile icon in the top right corner of the App Store to access the apps you own or have downloaded.

The list of apps that need updates is located at the bottom of this page. Apps that have been updated recently are displayed beneath that. 

If needed, compare this to how much battery life you have. If an app looks to be causing issues, close it and see if the battery life improves. 

Uninstall any apps that coincide with a recent upgrade and excessive consumption. Try reinstalling the application if it improves battery life after being removed.

Although it's a drastic measure, a new OS install might still be helpful, particularly if corruption affects your iPhone’s battery. 

For the most reliable outcome, make sure you have a backup of your device and connect it to iTunes before doing the reset.

Solution 4: Reduce the brightness of your screen.

Reduce the brightness of your iPhone screen to save battery life. It's really simple to do this: drag and tap the upper-right corner to open the Control Panel and manually reduce the brightness bar.

You can also ask Siri to lower the brightness. Alternatively, you can locate these adjustments under “Settings > Display & Brightness.”

If you want to shorten the time your phone waits to lock itself, select “Auto-Lock” from the “Display & Brightness” submenu. 

This way, if you set your phone down and focus on something else, you won't be using up all of the battery life.

Solution 5: Turn on Low Power Mode.

Your iPhone will prompt you to enable Low Power Mode to extend the remaining battery life whenever the battery level falls below 20%. 

However, you can also manually turn it on whenever you want. To do this, click on “Settings” and tap “Battery,” and flip it on there. 

The all-purpose mode, known as “Low Power Mode,” prolongs battery life by minimizing drain from active and passive sources. 

In addition to turning off the “Always On Display” reduces screen brightness and scales back background tasks like downloads and mail fetching.

Solution 6: Update iOS to the most recent version

While some iOS upgrades have great optimization, some optimizations are poor. 

So, wait a few days, review user reviews and news, and then decide whether to update to a newer version of iOS before doing so. 

Updating to the most recent version might resolve the issue, as you already saw the battery drain.

Here's how to get the newest iOS version on your iPhone.

  • Open “Settings” on your iPhone. 
  • Tap the “General” option.
  • Next, click “Software Update.” 
  • Tap the “Download and Install” on the next screen. You’ll only see it if an update is available.

Solution 7: Reset all Settings on your iPhone

Resetting your iPhone is the best choice if, despite everything we’ve discussed in this guide, you're still experiencing battery drain. 

You can select the “Reset All Settings” option from the “Transfer or Reset iPhone” screen since it allows you to reset your iPhone without erasing any data.

Your iPhone will reset its location, privacy settings, network settings, and other settings if you choose the Reset All option. 

You won't, however, lose any data. Still, make sure you backup your iPhone to iCloud before following the instructions below. 

  • Open “Settings” on your iPhone and tap “General.” 
  • Scroll down and select “Transfer or Reset iPhone.”
  • Select the “Reset” option on the next screen.
  • Tap “Reset All Settings” and follow the on-screen instructions. 

Solution 8: Contact Apple Support

If the battery life of your iPhone is decreasing significantly and it is less than a year old, contact Apple Support, especially if you have followed all of the instructions and have not noticed any noticeable changes. 

There's a chance that the battery is draining overnight due to a hardware problem. An official Apple Store can assist in resolving the battery drain issue. 

If nothing else, they can at least assist in identifying the source of the issue.


It can be annoying when your iPhone's battery drains quickly, but there are a few useful fixes to lessen the problem. 

You can improve your iPhone's battery life by checking that your iOS and apps are up to date, modifying the display settings, and controlling background program activity. 

Limiting push notifications and background app refreshes, turning on Low Power Mode, and lowering screen brightness can all have a significant impact. 

If your battery problems persist after you try these fixes, try resetting your iPhone's settings or contacting Apple Support.

You can prolong the battery life of your iPhone and have a more seamless and durable user experience by following these easy steps.
