Sanyo 4920 backlight question

I can't find an advanced manual online yet for the rl-4920,
and what comes with it is scant.

Something that strikes me as most odd is that the backlight
remains on throughout the charging process. I haven't yet found any
setting that would turn it off. In all other respects it behaves like
the backlight on other phones (such as the 4900), and can be set to go
off after selected intervals of 8, 15 seconds, etc.

Has anyone else got an observation about this? What am I
missing?

Thanks, DGI

Both of mine do the same thing. If anyone knows how to turn it off during
charging pls let us know.

FWIW, I've had plenty of phones that do the same thing. My T608's
backlight remains on during charging, even when the clock/screensaver
has gone active.

No idea here how to turn it off... but is it really that much of a
concern? The backlight is LED-based, so it's not like the light is
drawing a serious amount of power. It certainly doesn't affect
charging, and it's not like the backlight will "burn out" anytime soon.
The LEDs will probably outlast the rest of the phone.

No, you're right. From the technology point of view it's no
big deal. I have a general disdain for inefficiency and wastefulness.
And there is a harder to define feeling, eg: "why do I have to have a
light burning in the middle of the night?" Different from the waste
issue. It's just sort of senseless.

True, and I can certainly understand your point on the waste issue.
However, since a lot of the gadgets we use these days no longer truly
"power off" when we tell them to, and even wall-wart power supplies that
aren't connected to the gadgets they charge/power still draw current
(it's easy to tell, most remain warm if plugged in) I've kinda learned
to let it slide. The combined waste amounts to maybe a nickle out my
pocket every year. *shrug*

The thing I don't like about it is that I want to keep the phone in my bedroom, but I get annoyed by light in the room because my eyelids are thin (and because I like to hibernate 8 hours a day, so all the shades are closed, etc).

Plus I like the phone to light up and wake me up if I'm sleeping, not be a nightlight. That's just not a feature I was looking for in a phone! :-D

Here's the official manual from Sanyo, David:

So why not just turn the phone upside down? That will reduce the output
from the lcd dramatically (it's what I do), and besides, the ringer comes
from the speaker on the back, which will now be pointing up for you.

Only 1 way to turn off the blacklight for the screen power off the phone, other wise it'll remain on, personally i think of it as a design flaw, if you put your phone face down on mouse pad or well anything u can't see the light well <.<;
