This is available in Developer options in Android's system Settings. I'm trying to look for an equivalent in iOS. This is great if I want the screen to be always visible for screen updates/notifications. No problem with battery since it is plugged in anyway.

Is there a Jailbreak tweak for this?

This setting applies for both plugged and unplugged. I'm looking for something specific to a plugged device.


In the past there was an Cydia App called ScreenDimmer.

I hope you can find this application via your iPhone and fix your problem.

One of its features:

  • Doesn't dim the screen if the battery is being charged.

  • Too bad this is paid though. But a good answer nonetheless. – radj Feb 4 '14 at 1:36

    @radj I couldn't see anywhere that it had to be free anyway :) – Rob Feb 4 '14 at 7:07

After re-Googling, I found this post on MacRumors. It's not very detailed so I'm going to place the steps to get this working on a jailbroken device:

  1. Install SBSettings
  2. Go to Activator app
  3. Under Anywhere > Power > Connected: set to Switches (Deactivate) > Auto Lock
  4. Under Anywhere > Power > Disconnected: set to Switches (Activate) > Auto Lock

This is the first time I used Activator and my goodness, this thing is powerful.

    Activator is great indeed. – Rob Feb 5 '14 at 7:36

Activator means I can customise my phone down to the tiniest detail so it works exactly as I want it to work.
