I'm with a 5.0.2 D6603.
The issue I have is that the following Kernel wakelocks does not allow the phone to deep sleep.

I've just performed a sw repair via pc companion, and several factory reset. I'm running the Z3 with no apps.
It happens both with an LG G Watch R (5.0.2) and a regular BT Plantronics (voice only) headset.
Using the same BT devices with a Nexus 4, Nexus 10 and an LG G2 does not have the same effect. As soon as there is no usage the phone goes to speep immediately.
If we take the second device, I do expect a Kernel wakelock while speaking or streaming music. The phone is active any way while performing this task.
What is strange is that even if there is no activity the wakelocks avoid deep sleep.
What is strange is that if I move away from the headset (and the BT icon goes the "non connected" status), the wakelocks are always there.
The effect is that my phone (both on 4.4.4 and 5.0.2) almost never ever sleeps, and sometimes get warm. It is evident that the battery life affected a lot.
If I switch BT off, everything goes back to normal.
I did a further test, in the below sequence:
- BT ON + connected to a Plantronics headset => wakelock + device always on
- BT ON + disconnected to a Plantronics headset => wakelock + device always on
- BT OFF + disconnected to a Plantronics headset => no wakelock + device sleep
- BT ON + disconnected to a Plantronics headset => wakelock + device always on
Any solution?
Is it possible that this is an hardware problem?
This thing is driving me crazy!!!!
Thanks in advance.
