Is bluetooth getting switched off by some power saving feature?

CJM2 — Sun, 07 Aug 2016 20:12:55 GMT

I have a Parrot hands-free Bluetooth device in my car. It has worked fine for many years with many different phones. My Xperia Z5 compact has connected to it automatically most of the time for the last eight months or so since I got the phone.

The phone recently failed, and I had it repaired. Since then I have been having problems with it not connecting automatically. If I tell the Parrot to connect it gets ‘connection failure’. If I unlock the phone and open the Bluetooth screen it connects immediately. If I then lock the phone it stays connected and works fine. If I switch the power off and it disconnects it will reconnect immediately.when power is restored.

Similarly, if I open and close the Bluetooth screen on the phone before starting the car it connects immediately.

It is acting like Bluetooth is switched off after some time by something which I cannot find. I have not done any timing to find out how long this takes.

Help.

Do you have stamina mode on?

No. No power savings options that I am aware of.

I don't understand 'Settings > battery'. I have no battery option under settings.

As I said before I have no power saving measures enabled under power management.

I was doing some more playing around, and I set smart lock to recognise the Parrot device as a trusted device. It now works fine, connecting quickly every time.

I don't understand it.

Settings > about phone > which android version and build number does your phone has?

Power management shows absolutely nothing of interest.

Links to activate stamina mode or ultra stamina mode, neither of which are activated, plus 'queu background data' is activated.

I repeat, why do you want to know? I do not understand what caused the problem but I have apparently bypassed it

Me too. Every time with my Xperia Z5 Premium. Apparently there is some sort of fix in the Maeshmallow 6 that includes:

All of the latest bug fixes and performance updates
Improved battery life
Improved camera functionality and stability
Improved sound handling
Improved handling of Bluetooth connected devices
