Bluetooth on will obviously drain the battery more than if it is not but I never found it a problem on my T68i and certainly no problem on my T610. I use my HBH-30 and also bluetooth to my ipaq many times a day.

test it.
leave bluetooth on for a bit, and if it drains the battery to quickly, and goes dead within an hour... dont leave it switched on..

On my t68i I could set bluetooth to "automatic" so it only turned on when it wae needed. I havent seen this on my t610.
Maybe its "automatic" automaticly.  |

That question was already answered, MixiN :-) But i don't think masseur leaves it on when he sleeps... So forget about 24/7 :-D

MaThIbUs, well fortunately I don't sleep with you so you can't comment on that! 
but actually I do leave bluetooth on all the time however (and I am sure I have said this many times including just yesterday) I don't try to make my battery do the marathon... my phone sits on the charger every night. There does seem to be some fascination in making batteries last 3, 4 or 5 days but surely we do all go home every night?
So for Snow-Munki I wouldnt worry and just leave it on all the time!

ahhh,
but i thought its better for batteries to use it all up and then charge it.
Its bad to charge a half charged battery, if that makes sence.. or is that no longer the case? |

no, not lithium ion batteries, there is no memory effect. that only applies to nicad and to some extent Nickel Metal Hydride batteries.

Ok, let's see if I can help (first post here, I know I have no credit, but I do study Elec. Engineering at Imperial College...)
Bluetooth was developped with portable devices in mind. Infact, all of the 7 founders produce either mobile phones or handheld computers. BT works on a very high radio frequency, not used by any communication system and studied to not interfere with microwaves too. As it is meant to work only with another device, the application will run only when another BT device is in range, and will be totally off otherwise. Infact, if you spend a day at home with your BT on, the only thing to affect battery consumption with be the extra flashing LED. Things change slightly when going around. If, say, somebody is looking for BT devices and you're in their 10m (or 100m, depending on the device) connectivity bubble, then your BT will also go active, so if you go around somewhere where lots of people are using BT, your battery will resent it. Elsewise, nothing will change.
I hope this cleared some ideas up. If you have any questions about BT, I'll be happy to answer (I just made a study on it for Uni). You can email me at spliff@supereva.it
Just bought a new Nokia? A word of advice: flush it down the loo and buy a SE. |

Bluetooth is either ON or OFF. No automatic setting.
I can use Bluetooth everyday and Bluetooth is always on. I always use GPRS for intenet over bluetooth and I can get 3 days out of the battery no problems.......thats also using the camera functions, chaging themes, (which I seem to change like underwear) and genreal stuff like playing games. Of course there is that part where its a telephone too. I make/receive several calls also.
Who gives a toss anyway, if you were going away to a remote place, lets say camping in the bush or something well then youd turn a lot of those functions off, use your phone sparingly and youd get 5 days easy. Besides youd have a car and have the car charger anyway.
How far away does one get from a power source these days????
Put it this way the t610's battery is good enough to have IR, bluetooth, loud rings, play some games, surf the net and take lots of pictures as much as you want provided you return from your prehistoric cave to civilization every 2 - 3 days. |

AFAIK leaving your phone in automatic (if there's that mode available), won't drain the battery for use with an headset.
Let me try to explain this. To use a headset firat you have to pair both the phone and the HS. After doing that your phone get's to know it's passkey and everything it needs to work with.
When receiving a call, your phone just makes a confirmation of the presence of the HS. If it's there it'll connect to it, if not just answer it normally.
So in fact it's not "always on", it's "always on standby".
