The time it takes to establish a connection via mobile data (usually one or two seconds) depends on a ton of factors, such as the radio firmware in your phone and the particular configuration and signal reception of the cell tower you’re connecting to. These obviously can’t be controlled by JuiceDefender; however, if you’re experiencing long delays, there’s a couple of configuration tricks that might help:

• Go to the WiFi control section and make sure WiFi preferred is disabled

• Tablet mode, while saving a ton of juice, might increase connection time significantly, try disabling it if it’s enabled.

• Finally, go to the Troubleshooting/Screen section in the About tab and disable Enable after unlock; this will buy you roughly one second – or the time it takes to unlock your phone.

• Some users have reported that enabling use APN method in Troubleshooting results in mobile data reconnecting more reliably; if you try this, remember that if you uninstall JuiceDefender without disabling it first you’ll have to edit manually your APN to restore connectivity.
