Bluetooth battery hog?

    I leave Bluetooth turned on all the time. It is responsible for 28% of my battery use, even though I have hardly used my headset. Is something wrong with my phone?

    If the Phone and headset are on and paired it's using power. The best way to avoid it would to either turn off the headset while not using it or disable bluetooth while not in use.

    Bluetooth using a lot of power is nothing new. It always has ever since it was first put into phones.

    Mine reads that way too even when nothing is connected to BT. Really strange. Generally BT only uses 4% of the battery. That's has been on every Android phone I've owned so I always leave it on. I'm not sure what to make of this but my battery has been good. I think it is a miscalculation but you can turn BT off and see if you generally get 25% better life. Moto would have to have made a major FKUP for BT to use that kind of juice. Their headsets are the best and BT has been flawless in half dozen Moto phones I've had.

    Btw, I too would have BLUETOOTH on all the time (like I did on my OG Droid).

    Yesterday I had my Bluetooth off on my Bionic and I swear I get at least double the Battery Life.

    I have the same issue. BT using the same %amount of battery as cell standby. Even when nothing is connected to BT. Maybe it's a bug that needs to be addressed.

    I also left BT on all the time with OG Droid. BT only popped on when I get in the car. I saw that Droid3 has bug fixes recently incl. cell standby -- hoping for a fix. With BT on all the time with the OG Droid/no devices connected, it wouldn't even touch the battery until something connected.

    Yup, same issue here. My Bluetooth percentage is about the same as cell standby when I leave it on all the time. Turning Bluetooth off seemed to improve battery life a little, but not a lot. Interestingly, the Bluetooth seems to use about the same percentage whether you are connected or not, or whether you are actually listening to something. For example, I listen to music via Bluetooth at work appx 5 hours per night and it still uses the same 25% battery life that it shows when nothing is connected to Bluetooth. Hopefully, this is either a miscalculation or a bug that can be addressed by Moto.

    Yea I really don't think the BT is actually using that much battery. I would notice it. I leave my BT on 24/7. My phone has been unplugged since 9am and it's 4:30 with wifi and BT on, all my accounts syncing, phone calls, email and remote desktop and the battery is still at 70%. No way BT is chewing up battery.
     
  9. Add me to the list of people seeing this problem. I also would leave BT on all the time on my OG Droid and that battery would rock all day long with BT barely doing any damage. But on this baby, 25%? Now I gotta turn the BT off when I'm not in my car and then back on again when I get in my car...pain in the butt
