Did you know you can actually save power on your iOS device by changing some of Siri’s features?
The main one you’ll want to change is the “raise to speak” option. This enables you to speak commands to Siri without having to raise the device to your ear, like you’re having a normal conversation.
To do so, head to the Settings app, and then to the General tab, and then to the Siri page. There, you’ll want to click on “raise to speak”, which will shift the function to “on”. You’ll find you may save some battery power.
