Bluetooth sucking up battery?

My iPhone 5 is set up to automatically connect the phone and audio. I noticed this took a lot of the battery power even when I was not bluetooth streaming audio or on the phone. I then set it to just connect the phone and disabled audio. This helped somewhat.

Makes sense. BLE is using a lot of power if it is constantly searching, trying to connect.

My iPhone 5 also gets it's battery sucked down and gets very warm just being connected to the car, not streaming anything or using the phone.

use usb cord... you get better audio fidelity plus you charge your phone at the same time, a win win!

Except with the glitchy software in the 2014's, the USB often kills the streaming connection...we need an update badly. I'm to the point that if the phone needs charging, I have to listen to FM or SAT. If I want to stream over bluetooth, then I don't get to charge the phone.

The iPhone 5 has battery issues. Apple knows it, but they won't acknowledge it. Also double click your home button and shut down any apps running in the background. That might help.

Same here! I stopped connecting my phone to Bluetooth. My iphone 5 gets instantly drained just being connected.

Has anyone else had problems with voice quality on the hands free? My 2008 IS350 had great bluetooth call clarity and did not drain my iphone 5 battery, with this car people always stop to ask if they are on speaker or cant hear me when Im driving over 45 mph.. Ive tried adjusting the mic sensitivity and volumes but nothing helps.. really a bummer

I haven't noticed any battery issues with my iPhone 5.

Instead of USB though, which has the limitations mentioned above, you could just uses an auxiliary cable, which will use almost no battery. It's the same as headphones. The only downside is you have to navigate and choose what you want on your phone instead of in the dash. Though frankly, that might be faster in my experience.
