If I leave my phone UNTOUCHED for a whole weekend (Bluetooth enabled, but not connected to anything), it uses 2-5% of the battery. That's pretty good, I think..
However, when I go to work, the Bluetooth connects to the car's stereo for hands free. This immediately starts to drain the battery at an alarming rate: 8-10% PER HOUR!!! This means, some days, it doesn't even last for a whole work day, without needing a recharge. If I start to actually USE the phone (calls, apps, SMSes etc) it goes even faster.
This consumption is twice the amount GPS is using (e.g. Endomondo uses 4-5% per hour). GPS is generally refered to, as the most battery consuming feature, but that's not true in this case..
Is there any way to improve on this, e.g. by reducing the signal strength of the Bluetooth antenna (less watts = more battery time)? It's not nessesary (for me) to have a 5-10 meters range on my Bluetooth, 1 meter will most likely be suffient.
Android v4.3 (with all updates the phone can install inself) is installed.
