Hi,
I rooted my N1 and installed a flashlight app (N1 Torch) that uses the phone's LED flash. It warns you that continuously using the flash might break it, though.
What has been your experience? Does "continuous use" mean "hours", "minutes" or just "more than the 0.5 seconds the flash is supposed to turn on when you make a photo"?

I think that using it for a couple of minutes would be fine, the problem is that if it gets too hot it could damage the the phone especially the camera. I remember that I installed a similar program on my nokia n70 and several times happened that by accident i turned on the led while the phone was in my pocket, I only noticed that when i started to feel something burning in my pocket Now my n70's led and camera doesn't work anymore... so just be carefull not to turn on the led by accident
I had read that the LED flash was designed for quick bursts. If that is true than constantly running it could - at least - burn out the LED bulb. I doubt is it user replacable, so that is not a good thing.
I have hoped to use Torch too, but have decided its just not worth it. I will just use the lit up screen as a flashlight.
Yeah.. I'm thinking about uninstalling torch I get random clicking after I turn the app off
It's an LED.. by default LEDs are low-power, have low-heat emission and super long lifetimes. They also tolerate turning on/off repeatedly for extended periods of time.
I somehow doubt you could do any damage to the phone/LED.
Has anyone even heard of doing damage this way, or is this just speculation and ass-covering in case something goes wrong?
my old sony erricson w810i LED flash lasted for atleast an hour of continuous use with no ill effect.
LEDs don't get that bright either, not the ones you are thinking of. The LED in the nexus one is much brighter than "usual", and it's also much smaller.
High power LEDs (HPLED) can be driven at currents from hundreds of mA to more than an ampere, compared with the tens of mA for other LEDs. They produce up to over a thousand lumens. Since overheating is destructive, the HPLEDs must be mounted on a heat sink to allow for heat dissipation. If the heat from a HPLED is not removed, the device will burn out in seconds.

Obviously the LED in the N1 is designed to deal with its heat under "normal usage" for a camera flash, and it probably can handle longer usages than the stock camera, but I wouldn't push it too far.
Edit:
If anyone wants to use some debug tools to find how many mA the phone pulls when the flash is on vs when its off, they could probably look up the usual heat generation for an LED of that size and see how 'safe' it is to run.
I just contacted the developer on google wave, waiting for his reply now. Please give me your address if you want to be added to the wave.

High power LEDs do get hot (i have an LED flashlight that gets quite hot after prolonged useage. it chews up batteries as well) and, ill bet that continued useage at high output can damage it.. and the camera... theres a reason that its not enabled stock
A way around heat and power is the cycle the LED at 30-60hz. I am unsure if the developer of N1 Torch could make it happen with software alone though.
Not sure if this helps but I have shot several videos and even changed a flat tire with my BB Storm LED. Besides draining battery, the only thing I worried about was space on mr MicoSd because I could only leave it on continuously in video mode.
I used mine this morning for about 5 mins and no problems.
Still works and so does the camera.
Wait, so the Nexus One uses the High Power LED, not a regular LED?

no he was just using that quote to prove that some leds do produce heat. judging by the brightness i would say its relatively high power, and because htc might not have mounted the led on a heatsink big enough to keep it cool after prolonged use because they designed it for a camera flash, not a flashlight. so better safe than sorry.

Ya! I had a K750 (flashed with the W800i firmware) that had as one of it's features, used the flash as a torch and a SOS beacon.
SonyEricsson's XPERIA X1 (Win Mo device, HTC manufactured) has an app for the flash too. The app has two options.
First (dimmer) is mostly OK (not recommended for hours of use either).
Second (brighter) caused a meltdown of the LED's plastic holder if used for long enough. The holder melted over the vibrator motor, thus shutting it stiff and ruining it.

Folks should stick to things they know. There are many VERY high power LEDs, such as those used as a flash. Depending on the application they end design may be to be used in short bursts because they create so much heat. LEDs waste LESS power through heat dispersion than a conventional lamp, but they do indeed create heat. I've seen LEDs that need a heatsink 10x their size to keep them cool. In the interest of size I would be willing to bet there is not enough heatsink on the LED flash to be able to use it for extended periods of time without burning it out.
comparing light sources from different phones as others have done here is silly. Unless you are positive that they are the same LEDs and that they have proper cooling behind them, then don't compare.
Source - Me. almost 20 years in the semiconductor design and test industry
Seconded. It's possible the LED is being driven at peak currents, or beyond too, which is fine for a short burst but not for prolonged use.
I'm the developer of N1 Torch, and was pointed towards this thread. So I can offer some answers and insight...
Standard brightness is supported 'naturally' by the LED kernel driver. I tell it to come on, and it comes on until I give it a command to turn off.
High brightness is only enabled by the kernel for ~0.5 seconds before the kernel turns it off automatically. I simply send the command repeatedly to keep it on.
I had the app tested on a sacrificial N1, and the following were the results:
- On standard brightness mode, the torch ran for over 1/2hr continuously with no problems or heat issues detected.
- On high brightness mode, the torch was noticeably warm after 1/2hr, and there was a bit of a 'heat' smell coming from it. After a further 18 minutes (total 48 minutes) the LED started flickering of its own accord and was hot. After cooling, it resumed working normally (no idea how the lifetime was affected).
You can use your own judgement based on these results (and of course, YMMV due to manufacturing differences). I would be happy to say that standard brightness is fine for extended use (1/2hr at least), but try to limit high brightness to a few minutes at a time.

Short answer, unless HTC is running damaging levels of voltage through the LED and you have the flashlight on constantly you have nothing to worry about. Even if you run it 24/7 the low end estimate for most LED's is 2.8 years.

That may be the case for average LEDs, but high powered LEDs need proper heat dissipation setups. Philips Lumiled K2 LEDs have 1W versions that will burn up without a proper heatsink.
But since HTC released this as a stock app, I'm sure it's fine. I do prefer the "LED Light" widget over HTC's app.

Light widget is nice for quick turn on/off, but I hear it causes a wake lock and besides, the HTC one has more features (3 brightness modes, SOS, and blinking) and it turns on when you first press the app icon. Just hit back and you turn off the flashlight. I guess you can't leave it and use another app while its on like you can with the widget, but what are you doing using a flashlight while texting? lol. Anyways, if it wasn't for the wake lock, I'd still keep the widget around, just in case.

It doesn't matter how long they last when they are attached to a proper heatsink as mentioned already in this thread.
The LED's in the camera flash are capable of being driven hard, but are intended only to do so for short periods (when the camera fires it's flash). There is at least one application out there that allows you to put and hold the LED's at that power level, and if used for extended periods at that high level the potential of overheating and destroying the SMD's is there.
I am sure that HTC has determined the maximum thermal dissipation of the SMDs and built their flashlight application around that, knowing that users will be tempted to use the application for longer lengths of time.
Changing the colour of the trackpad light?
Changing the colour of the (and using) the charging light?
What ROMs let me do this? (MIUI, CM6, Sense based)
I know there were threads ages ago, but I don't know what to search. And the info will be old.
The trackpad light is white, you can't change it. The LED near the top is either green or amber.
I use the "LED Me Know" app from the Market to control which one I want to flash etc. Don't know which custom ROMs handle it natively.
The stock Sense ROM flashes the trackpad light if you set it, but only every 10 secs or so.

My version of LED Me Know (the latest, as far as I'm aware), lets me select either an amber, green or "trackpad" notification. i.e. the amber and green ones are for the light by the speaker grille, and the trackpad light doesn't have a colour selection (it's only white).

Not sure about any other roms... but in the stock rom if you let the battery get critical (lol... less than 5% I think) it will flash pure red every 5 seconds or so. There's no way I'm confusing it for amber. Its clearly red.
Also: if amber is a combo of red and green, then the green led is not running at 100% while displaying red. It would have to be something like 100% red power, 60% green power. Reason? Download the app "Covedev Design" and enable amber, then green as well. You can clearly see the led change color slightly.

I just found this out yesterday but the Note 2 has a separate controller for gathering sensor data.
In short, unlike previously where the CPU had to wake up to gather data, a dedicated low power processor takes care of this!
It works for the accelerometer, magnetosensor, and orientation sensors for sure.
It may also work for the other ones.

Thanks to everyone for that!
Explained well! And I'll definitely use it from now on! It seems it might possibly use less battery to use this feature than having to tough the screen sometimes to stop it from turning off, and if you're not looking at it, it will just turn off like it normally would.
Basically, I have my timeout set to 1 minute.
Normally, I have to scroll up or down when I see the screen get dim moments before turning off. That's annoying, and sometimes probably spend more time touching the screen and messing something up when trying to do that.
With Smart Stay, if I'm looking at the screen, it checks for a split second (and you see the little "eye" symbol pop up) and it never dims out out either. That is really nice, and I don't have to keep messing with the screen to make sure it doesn't time out, which probably saves battery too. It continues to check for a split second every 1 minute.
If I'm not looking, it simply turns off.
Will definitely be using it from now on!
I also tried the feature where the red glowing sensor stays on ALL THE TIME WHEN THE SCREEN IS OFF and you can wave your hand over it to see missed calls, song playing, status bar, etc...
I'm gonna pass on this last feature. Not very helpful, and that must drain your battery somewhat faster, as you can even see the red glowing sensor on all the time when the screen is off. No thank you.

For a few years now, there has been another core or companion core in smart phones that handles minimal situations. It is a low power core that does not require the resources of the main processing unit. Tegra calls it “4+1” technology which means there are 4 cores running at the same speed and a slower fifth core that can handle most of what you’d be doing on your device. Here is their comments:
http://blogs.nvidia.com/2012/02/technology-formerly-known-as-vsmp-gets-a-new-stage-name-4-plus-1-2/
VSMP has been around for years and Samsung has used it in their system architecture. Back when one of the big things was increasing processing power one of the big problems was dealing with the low power core.
It just doesn't make sense to use power when you don't need it. Its like the V8 engines which drop to 4 cylinders at the traffic light to reduce gas consumption.

I think there is a difference here as the GS3 does NOT have this feature, you can test this by turning "smart rotation" off then testing the autorotation speed of both phones - which is how it was demonstrated to me. The Note 2 is noticably quicker.
I guess what im saying as in the OP , it is not part of the exynos SoC at all. The microprocessor is a seperate package on the PCB

Its dim and it blinks unbelievably slow. I dont understand what they were thinking. Notification lights should be bright and obnoxious to.... notify you.
Has anyone found a fix for this yet? The notification light on mine only blinks once then stops. How is this suppose to notify me if I missed a message if it only flashes once and is extremly dim. The Samsung Led light are are way better. Is there going to be a patch for this problem?
Hello fellow RFDer - to the OP
I used light flow with the custom flashing rate, set at 1000/1000 (so 1 second flashes with 1 second gaps) and it seems to work well. Setting any of the other settings (slow - fast) didn't make a difference. I really can't wait for CM where all these items are built in and we dont have to mess with 3rd party apps.
It worked for a while yesterday, now it stopped working. I've since installed Light Flow with no luck, have Light Manager right now (all free so far), but still without success. I've always been a Blackberry person and had a GNexus before, so I'd be lying if I said I wasn't spoiled with a working light.

It does not work for missed calls, Gmail messages, text messages or while charging!
I had installed Lightflow and it was a little buggy, but I think, the LED notification should still work for all types of notifications?
I have also factory reset the phone and have the pulse notification option under the display menu turned on, but still no success.
Any help/replies will be much appreciated.
I have no issues with using light flow.

Thanks mate, how about without light flow? Does lightflow drain a lot of battery?

Light Flow only drains battery when you leave a notification unchecked for long periods of time (i.e. the notification LED flashes for long periods of time). Naturally, the longer the LED flashes, the longer the wakelock.
In normal use, the battery hit is negligible (in my opinion).
