“Hey Siri” is an amazing feature found on the iPhone that let’s you talk to Siri without having to even touch your phone. Officially it only works when your iPhone is plugged in and charging. Unofficially here is now to enable it to work anytime.
The process is very simple. First make sure that “Hey Siri” is turned on:
- Tap on the Settings App
- Tap on General
- Tap on Siri
- Turn on “Allow Hey Siri”
This will turn on Hey Siri and allow you to speak to your phone handsfree. However it will only work when the phone is plugged in. This is to prevent your phone from draining battery and losing power. To have your iPhone stay on all the time listening for “Hey Siri” would take a lot of power. So your iPhone will not allow you to use Hey Siri unless it detects that it is charging.
But now here comes a neat trick! Here’s how to enable “Hey Siri” without having to be plugged in: put your iPhone into a battery case. This will put your iPhone into a state of constant “charging” and “Hey Siri” will be active all the time, whether you are plugged in or not.
Here’s a cheap and well reviewed battery case for the iPhone.
Hope that helps!
