    Y'all probably already know this by now (hey I'm a special case:confused:) but if you turn on LED Flash for Alerts in Accessibility you get a cool effect for alerts especially if you're rocking a clear case. The borders around the case lights up if the phones is laying on a flat surface.:apple:

    And if you're jailbroken you can install FlashAlert. :)

    Just be careful when the phone isn't lying on its back and it looks like you are taking a bunch of pictures with flash to someone or a darker room/location gets lit up with flashes unexpectedly.

    Been a featured since iOS 5 circa 2011.

    I used to have it enabled, but I disabled it for two reasons:
    • Flashing strobe alerts inappropriate in dark scenarios (theatres, airplanes, etc.)
    • Flashing strobe awful when morning alarm goes off.

    Seeing that LEDs are one of the biggest consumers of battery life...and now that the flash has got 4 LEDs...thanks but no thanks.

    Are you saying LED flashes are one one of the largest contributors to battery depreciation? Source/citation please?

    Please re-read. I said LEDs consume lots of power, not LED flashes. This stems from the common fact that one of the biggest battery drainers in a modern smartphone is the screen. In the iPhone's case, it's an LCD screen with LED backlighting and the backlight is one of the biggest consumer of battery (1-1.7W depending on brightness vs SoC at 2-3W at max clock). Obviously the SoC is mostly idling, drawing very little power while the screen is always on.

    Now back to the LED flash on the back of the iPhone, it definitely is quite power consuming but it will actually be negligible because it's like the SoC. It's on and off and therefore when averaged out, it doesn't consume much.

    So, it's my bad I made it seem like if you turn on flash notifications it will impact your battery life noticeably. Let me clarify, I don't think it will impact your battery life, if any at all.

    But I still stand by my claims that LED backlight and the LED flash both consume a lot of power.
