Recently got a car with bluetooth.  I have connected my car and phone.  Just driven for 40 minutes and this totally drained my phone's battery.  I'm sure this can't be right.  What can I do please?

Was the phone totally fully charged?

Yes.  Three bars on the battery sign. When I go on shorter journeys the battery is depleted, but this time it all went.

Could be that the phone and car kit are constantly transmitting to one-another.  Does it only deplete the battery in a big way if you actually connect and USE the kit, or does it work fine and do nothing until you make/receive a call or text?

The Samsung UI is a complex, unintuitive beast so I am not sure if there's a bluetooth "power save" mode as you get with most phones these days.  Check through the bluetooth menus and see if there is.  Also, presuming your car kit supports playing music over bluetooth, turn this feature off in your phone - again unsure of the Samsung UI so check through for bluetooth services and see if you can turn off A2DP.

Failing that, check with the car kit provider (ford, vauxhall, whoever) and make sure this phone is on their compatibility list.

Or buy a car charger...

Thanks for your reply.  As soon as i get in the car the phone asks me if I want to connect to my car.  I have to choose the 'yes' option: it won't let me say 'no'!  If I don't do this the phone is prompting me during the journey to answer the question.  I realise of course that this will use a lot of battery.

If I receive no calls the battery is significantly lowered.  If I receive calls, and answer them, the battery is drained very quickly.  There is no facility on the phone to use a 'power save' mode.

 My next step is to contact the garage.  My car is a BMW and bluetooth is  all integrated into the car.  There's a space for a phone in the car.  Perhaps I should have got a phone to go with it?  To be honest I was losing the will to live by the time the salesman got round to explaining the bluetooth after all the other stuff.  

I will contact the garage.  Thanks again.
