How do I stop Siri from draining my battery?

Unfortunately, if you notice that Siri uses much more battery than usual, you’ll need to limit some features like Hey Siri voice trigger or Siri Suggestions. If that doesn’t help, consider disabling Siri until an update fixes this. As you’re probably aware, under normal conditions, Siri shouldn’t use a lot of battery. Still, it does happen from time to time when the service lacks optimization, usually on newly-introduced major iOS updates such as iOS 16.

1. Disable Hey Siri

We must say that limiting certain functionality to save battery life is never ideal. It’s not the user’s job to do that. But, until Apple sorts things out, you might need to give up on some battery-extensive features. For example, the Hey Siri voice trigger requires Siri to always listen in the background. Voice trigger works even when iPhone’s screen is off. To reduce the drain, try disabling the voice trigger and recheck battery stats after some time.

Here’s how to disable Hey Siri on your iPhone:

  1. Open Settings.
  2. Select Siri & Search.
  3. Disable the Listen for “Hey Siri” option.Siri draining battery

You can still trigger Siri with the Side button.

2. Disable Siri Suggestions in Search and remove the widget

Siri is not just a digital voice assistant on your iPhone. It also learns usage patterns and helps with search results, among other things. It has a dedicated widget that suggests actions like Messaging a contact or apps you frequently use. These Smart features shouldn’t affect battery life substantially. However, if you still get battery drain caused by Siri, you might as well disable Siri Suggestions and remove the widget.

Here’s how to disable Siri Suggestions in Search and remove Siri Suggestions widget:

  1. Open Settings.
  2. Select Siri & Search.
  3. Disable Show Suggestions.
  4. Now, go to your Home Screen, tap, and hold on to the Siri Suggestions widget.
  5. Remove the Widget.

If Siri is still draining the battery on iOS, update the firmware.

3. Update your iPhone

iOS 16 just came out, and although we always expect fluidity and optimization from Apple, it usually takes time to optimize everything for all supported devices (from iPhone 8 to iPhone 14 series). With that in mind, keep your device up to date, and hopefully, the next firmware update will sort out the battery drainage caused by Siri.

To update your iPhone, navigate to Settings > General > Software Update and install updates if available.

4. Completely disable Siri

Finally, if none of the previous steps reduced Siri battery usage, you can try disabling Siri completely. To do that, navigate to Settings > Siri & Search. Once there, disable Press Side Button for Siri and Listen for “Hey Siri” options. Confirm when prompted. That’s the last thing you can do other than performing a factory reset on your iPhone and configuring the device from scratch.Siri draining battery
