There is a blue light that flashes on my Nokia N80. I looked at the manual and it said it was a light sensor. I don't know why a sensor would flash though.
Perhaps it is mislabelled and it is not a light sensor but instead an LED that lets you know that the phone is switched on. Is this normal? Does it drain the battery?
I ask because my battery lasted less than 24 hours yesterday, even though the phone wasn't actually being used for anything. Up until yesterday it seemed to have a lifespan of a few days at least. The phone is so recently bought that I don't have enough information about how long the battery lasts if it isn't used.
So. Any suggestions?
The flashing light is just a status light (not a light sensor).
Possible reasons why the battery was drained:
1. You have bluetooth enabled
2. You have your phone connected to a wifi connection.
Without use and the above disabled, you should expect the phone to have a standby time of 3days ish.
Yeah, its normal... in power save mode... (and yeah, I know.. a flashing light to power save?) 😉
Depending on which firmware your on, its activated anything between 15 seconds and 30 mins I think, and flashes to let you know your phone is still on, as everything else goes blank till you slide it open.
SO far as I can tell, it does nothing but flash.
I doesnt drain the battery in any noticible way like you have had... power saving mode it the single best thing you can do to save your battery other than turning the phone off.
As you have a new phone, it might be that its hadnt had a full charge... it may take a couple of charges to get up to go life, but dont expect any change from 48 hours if you actually 'using' the phone! :icon13:

Ok, that means the manual is wrong, because it definitely says it is a light sensor. Maybe the authors of the manual don't have good English.

Thanks. I have switched that off now and I'll see how it goes.
2. You have your phone connected to a wifi connection.
Ok. I do have a WLAN connection defined, but I assume it wasn't actually active because I wasn't actually browsing the internet. I went to the "connection manager" and checked and it said "no active connections". Is this all I need to do to ensure there are no wifi connections? I checked and I have a symbol on my phone which says that I have set the phone to automatically scan for wireless LANs and a wireless LAN is available. Is this scanning process going to drain the battery? I checked my tools, settings, connection, and for "wireless lan" I've got "show availability" set to "yes" and "scan for networks" set to "every 10 minutes". I'm changing the first to "never", since I don't really care if I get an icon on my screen which is updated every 10 minutes.
Without use and the above disabled, you should expect the phone to have a standby time of 3days ish.
Ok, that's a lot less than I thought it was. I thought it was rated at 7 days standby. Although my phone is supposed to be new, it is actually ex-demo, so there is a possibility that they have worn down the battery (but like I said, it seemed to be OK before today). The first day I got the phone I charged the battery overnight.
theres no chance of getting 7 days outta the battery... even 3 is being VERY generous...
If you want to get the most out of it then:
1. turn off BT
2. turn off scan for wireless networks
3. Turn off 3G (unless you really need it)
4. Turn on power saving
5. Turn down screen brightness
also, whilst wifi is connected your using more battery. So, if your not using wifi to browse... disconnect... you might have the wifi manager software which can do this for you from the front screen.

Hi Guys!
The blue flashing LED is a light sensor.
Try this :
Go under the sun. Slide out the keyboard. The keyboard is not backlit. Right?
Now cover the LED with your whole thumb. Make sure no light comes to it.
The keypad lights up.....
It is true, the led light is also a sensor. And to be honest, I never get more then a single day use out of my battery, but then i'm always playing with my phone.
And I do always have bluetooth turned on. It doesn't bother me charging it everyday, and if fpr some reason i need to save battery i will turn BT off etc, and screen brightness down as mentioned.
Enjoy the N80, tis a good phone! 😃
That LED is not a light sensor, simply because LED is Light EMITTING Diode. The blue led is, as kontraband said, an indication of standby mode. Also written in the manual.
However, the LED (V3 - CL-191S-HB1R-D-T "LED_STROBE"😉 and the Photo Diode (V1 - PT202MR0MP) are placed next to each other. Therefore if you cover the clear opening under the N80 name the Photo Diode will respond.
