One of the main features of iOS 8 is that it allows you to say “Hey Siri” to your device while itâ€™s connecting to aÂ power outlet and in return have Siri launched automatically. This means that you no longer need to hold the Home button to launch Siri.
However, the only way to take advantage of this feature is to have your device connected to a power source and then it would listen to your words. UntetheredHeySiri is a brand new jailbreak tweak that gets rid of this restriction. The tweak gives you the freedom to launch Siri automatically whenever you want by saying “Hey Siri” to your device.
Although this sounds cool, the tweak might impact your battery life when itâ€™s enabled since the device will always be listening to your commands to find out if you want to launch Siri.
Once you installÂ UntetheredHeySiri, head to its preference pane from the stock Settings app to configure it. From there, you can enable or disable Siri and choose whether you want the “Hey Siri” feature to always work or only when your device is connected to a power outlet.
Other than this, you can select the language of Siri, Voice Gender, Voice Feedback as well as enter your name so that Siri calls you by your name.
If youâ€™re not concerned about your battery level or would like to show off the “Hey Siri” feature to your friends without connecting to a power source, you should definitely check out this tweak.Â UntetheredHeySiri is available on Cydiaâ€™s BigBoss repository for free and requires iOS 8.
