Insomnia is a app which prevents your iPhone from really going to sleep. Apart from that the Insomnia Cydia tweak also allows background apps to continue to run and WiFi to work long after the screen has been switched off.
Frankly, it won’t help your battery much, but is useful if you are running a logging app that you want to keep working while your iPhone is locked and the display is off.
Insomnia allows applications to continue to run and WiFi to stay connected long after the screen has been switched off. Runs as a background daemon with a status bar icon and survives reboots and re-springs.
Just like all other Cydia tweaks, Insomnia app also requires a jailbroken iOS device to run on. So that means you also need to have a jailbroken device if you want to download the application.
Insomnia app is available for free at Cydia Store. Also there is a pro version of Insomnia tweak available known as Insomnia Pro at $1.99. The insomnia Pro provides you the ability to schedule a time for Insomnia to activate.
