How can I return from power-saving mode in Android 2.3? I'm using a Samsung Galaxy S II Epic (with Android version 2.3.6 installed), and whenever my phone reaches 10% battery life it prompts me to turn on power-saving mode (and I do).

However, once my phone is fully charged, I'd like to turn off the settings that power-saving mode comprises (lowered screen brightness, shorter display timeout, etc.)

I see no way to do this in Android except by manually going through the settings and resetting them to the non-power-saving-mode levels. Is there a better way?
Total guess here: press and hold the power button. Is there a Power Saving option in the popup menu?
