Part 1: Why Does iOS 17/17.4 Drain Battery?

With the new iOS update, most users are wondering does iOS 17 drain battery life. Although a new software update on your iPhone might bring minor battery drain issues, a few reasons can make the matter worse. As the iOS 17 update is new, most apps are not optimized according to the latest iOS. The apps not compatible with iOS 17 might drain more battery and cause other issues.

After updating your iOS device, if the user doesn't configure it properly and lets power-hungry features run in the background, it will put more strain on the battery. Users can also face the iOS 17 battery drain due to update-related bugs. Apple tries its best to remove those bugs with minor updates.

Part 2: How to Fix iOS 17/17.4 Battery Drain with Top 7 Ways

Here are seven most effective ways to fix the iPhone battery-draining fast iOS 17/17.4 issues.

Way 1: Reboot Your iPhone

If your iOS device's battery is draining faster after you update to the iOS 17 version, instead of trying other fixes, the first thing to do is to reboot your device. Sometimes, the system takes some time to adapt to the settings and features of the new iOS firmware, so it drains more battery to maintain device usability. You can fix it by turning your device off and back on and letting the system figure out the issue on its own.

  • Press and hold the power (Sleep/Wake) button until the "slide to power off" slider appears. Turn your device off.
  • Wait a few seconds and turn the device back on by holding the power button. You will notice the device producing less heat and working smoother.

Way 2: Force Restart Your iPhone

If a simple device reboot doesn’t fix the battery drain problem, try a force restart to refresh your iOS device. Here are steps to fix the iPhone battery draining fast after iOS 17 update with a force restart.

  • iPhone doesn't give you the restart option like Android. Press and quickly release the “Volume Up + Volume Down” keys one by one.

Way 3: Use Low Power Mode

Most users don't know about the low power mode and how it helps save their iPhone battery life. It is a battery-saving mode for iOS devices. You can easily activate it by calling Siri and saying, "Activate low power mode". In case that doesn't work, follow these steps to do it yourself.

  • Open the "Control Center" of your iPhone by dragging your finger down from the top-right corner. For a device with a home button, you need to swipe upwards from the bottom.
  • Tap on the "Battery" icon to activate the low-power mode.
