We all know that standard Bluetooth take some juice out of our phones. With the new Bluetooth 4.0 and more specific Low Energy, is it possible to only turn on the Low energy part of the bluetooth module, or is it "too deep" in the system. I have a Galaxy S3.
If only Bluetooth LE was turned on it could be turned on all day with not problem.

I've had my XDA II for a few weeks now and the battery life seems really poor. I don't have any long time limit backlight options set and if I use the PDA or phone, I need to pretty much charge it every 18 hours or so.
Any ideas if it's a problem or normal or what?
I've turned on my Bluetooth connection to see if that makes a difference, and then I'll turn it on only when I need it.
For automatic switching of Bluetooth on when it detects a signal and auto off when no signal i use Pocket Bluetooth Tools. u may want to check it out as BT always on will drain power. its common sense in that the more thats running the more power you will use. i dock my XDA2 everyday, i have a spare battery and its powered in the car so power issues are not a problem for me :wink:
You can get Pocket Bluetooth tools from here http://www.bluetooth.jazztel.es/download_e.html
NB. install Bluetooth tools and then bond your devices otherwise the auto on/off doesnt work as i found out.

this apply only for using bluetooth for headset and recieving a call
nothing else
if you use your xda for bluetooth gps or activesync or ......... you have to be the active party and if another bluetooth device as a xda or a cellphoen try to send you stuff by bluetooth i'm pretty sure that bluetooth tools will not help you
Thanks for that advise. I thought the BT thing would kill my power.

i dont have a BT headset. i only use BT for my GPS. when i turn on my BT GPS, the Bluetooth Tools detects the signal and starts my BT stack. when i turn off the BT GPS, Bluetooth Tools turns off the BT stack off when no signal is received for >60 seconds.
As long as the device is bonded after Bluetooth Tools is installed i would say that the auto on/off function would work for all devices. the auto on/off would not work if i bonded my GPS before the BT Tools. Bond after installing BT Tools and the auto on/off works. just my experience with BT Tools but without any other devices myself i cannot confirm it will work for other devices.
A weird thing has happend to my Magician - Bluetooth, which I don't use very much, gets turned on whenever I call out. It seems like this started to happend after I fiddled around with BT tools (now uninstalled).
Any tips on how one can fix this?
the coz of Pocket Bluetooth Tools ,it turn bluetooth ON automaticlly when u call or recived call, if that bother you install the previous version 1.0.1.2... 8)
Yup, that's one of the settings - one of the better features - of Pocket BT Tools.
What is the advantage with that? For a headset?
yes
The automatic turning on of Bluetooth, is not a good feature, though it might be if there was an option of turning this feature off.
I found that the automatic turning on off Bluetooth uses up your battery power much faster as you never remember to turn the Bluetooth off.
huh ?
my bluetooth tools turn bluetooth off again after the time set for it to autoturn off you know that clock in the today part of bluetooth tools
if you play with a regeditor you can set the time 100% yourself
Hi all
I have a problem in my Chrysler Yoyager (town & country). When my smartwatch 2 is connected to my S4 I get disturbance when trying to talk over the cars handsfree. When I turn off the smartwatch the sound becomes normal again. No I am a little bit confused. Is this a problem with bluethooth in the phone, in the car or in the SW. So far I have not figure out what the cause is.
I dont like to turn off the SW in the car. Then I have to look at the phone while I am driving. My wife dont like that.

This problem has been reported in the past also from other users:
http://forum.xda-developers.com/showthread.php?t=2489149
As it generally doesn't occur with BT headsets or other car kits, I suspect that it's related to some protocol incompatibility between the BT stacks.
On the S4 try disabling all unwanted and unused BT profiles between your devices within the BT pairing settings menu.
OK, thanks I missed that. I was able to improve the sound following the discussion in the other thread.

Bluetooth in not a "collision avoidance" protocol like Ethernet. Therefore this interference is quite common between close Bluetooth devices.
I use my Nexus 7 (2013, Android 6.0) as a car mount. It has been useful for navigation and multimedia. To have internet connectivity, I pair my tablet with my phone (iPhone or Blackberry Classic) via bluetooth.
I am facing an insignificant but tedious problem. When I enter my car, the Nexus does not pair automatically with my phone. I have to go to bluetooth settings and pair manually. I am wondering if this is by-design or if there is a way to make it pair automatically.
On a side note, is there anyway to flag a specific bluetooth connection as cellular/mobile data, the same way we can flag wifi hotspots?
P.S. I am not using Wifi hotspot to reduce energy consumption of both phone and tablet, and mainly because the poor iPhone sends the wifi-hotspot to sleep, if inactive for a while.
Hello everyone!
I noticed that during conversations with the car speakerphone, the bluetooth disconnects sporadically, forcing me to use the phone with my hands.
Same problem also found when connecting the phone to the car via cable to use Android Auto.
Any solution other than "Amazon returns"?
Try disabling all power management for starters.
No issues with the new CX-5 radio... As mentioned - check the power management. Theoretically, it could be some RF jamming / noise caused by your appliances or outdoor devices - have you noticed the places where the disconnects had happened?
