Meta Question

Would a reversed out (i.e. light text on a dark background) mobile Fluther site significantly improve battery life for mobile Fluther users? Plus a bonus iPhone hack.

Asked by kevbo (25603points) July 9th, 2009 from iPhone

First the hack… If you have stray characters at the end of your text that you can’t get to using the iPhone cursor, use the copy/paste tool near the characters, drag to select them and then cut. VoilĂ !

Now for the Q. Obviously, the 3G iPhones have a shorter battery life. I learned from another owner that the battery on her new iPhone was getting killed because the wallpaper or desktop was initially configured as white. So, I’m wondering if there’s an opportunity for efficiency with the Fluther site in particular but also for mobile sites/apps in general.

It is my understanding that that issue was tied to CRT technology.

Yes.

Screens are like light bulbs (stare at a white background in the dark and close your eyes to get the jist of what I mean). Darker backgrounds use less light and are therefore less battery-intensive. I say go for it.

I wish I had an iPhone, sometimes.

I love the idea of a phone app for Fluther. Why just for the iPhone though?

Fluther works great on my phone’s browser but I would definitely use an app if it made things easier.

I never thought of the brightness of the wallpaper being a factor. I suppose that I need to find a different wallpaper than the one I have been using to see if it helps.

Great another reason to justify an aditional $80 to my monthly Cell phone bill.

I totally agree. Fluther needs its mobile site revamped or have some sort of Java app released.

I have a Blackberry most of the time and lots of other people have mobile phones that aren’t iPhones…we’re sort of left in the dark.

Oh, here we go again. THIS IS A MYTH THAT NEEDS TO BE DISPELLED!

When Google and other websites “switch to black” once a year, it is a purely symbolic gesture. The power expensive component in an LCD matrix display is the backlight, but the backlight is not selective.

As in, when a portion of the display is black, the backlight is still on—it’s simply covered by the filter matrix. You’ll notice that some light is still able to leak through, and that an all black display still has a blueish glow.

The only way to reduce the power consumption of your display is to turn down the brightness.

@Grisaille – But my point is that lcd screens don’t have those issues. Actually It is the reverse in that it uses more energy to make them black

richardhenry's avatar

@Bri_L Ha, exactly. Polarizing the filters to create the black actually consumes slightly more power.

richardhenry's avatar

From Google, emphasis is my own:

We applaud the spirit of the idea, but our own analysis as well as that of others shows that making the Google homepage black will not reduce energy consumption. To the contrary, on flat-panel monitors (already estimated to be 75% of the market), displaying black may actually increase energy usage.

Hey, I’m just a caveman. Thanks for the GA’s. :-)

@kevbo – your world of lights and noise confuses me, but I do know this. My client deserves $1.2 million in compensatory damages, and $2.3 million in punitive damages.

Grisaille's avatar

Ahhhhhhhhhhhh.

Dsregard my useless comment up top, then.

kevbo's avatar

@Bri_L, wicked LOLZ, my friend.

Bri_L's avatar

@Grisaille – Your comment was and is true for CRT monitors though so it isn’t useless!

@kevbo – The first time I saw that I thought what is this, but I couldn’t help laugh. Now my Dad and I use it to break the silence when we are stumped.

“Did you try to remove those two ram and swap the others? Yes?............Look, I’m just a caveman.”

I love that the about page for Blackle totally omits the fact that the report on energy saving they reference was back when the market was predominantly CRT monitors.

I hope they’re enjoying the $$$ they must be making through affiliate search. =)

@richardhenry Many thanks- I like Scrat and will now put him back.

I keep my screen on the darkest setting most of the time and the battery life holds all day.

GA for RH.

@Grisaille . . .—Get an iTouch. You get all the same cool shit without the annoying phone feature.

richardhenry's avatar

@Blondesjon You don’t use a phone? Or do you carry two devices?

Blondesjon's avatar

@richardhenry . . .I have a separate phone that I try to ignore as much as possible.
