Bluetooth randomly disconnects after update.
Dell vostro 5470, n7260 wifi card, upgraded to win10 from win8.1. Bluetooth used to work fine my bluetooth headphones keep disconnecting for no obvious reason. That is, sometimes after ever changing time of idling (it can be seconds to hours), sometimes exactly when I start to play music, sometimes after 15 or so seconds after music play start.
I have tried turning off the "allow to turn off this device to conserve power" in device manager for these three: bluetooth, wifi (just to be sure, because they are on the same chip) and the device itself under Human Interface Devices.
All the bluetooth services in services.msc are up and running.
Have tried multiple drivers. Win10 automatically gave me the latest, but I downgraded to 2014 driver from Dell's page for my laptop, I think I had this driver on win8.1, when it was working fine.
And I have tried running the laptop in "high power setting" mode.

There should be a more direct way of doing this, but as far as I know there isn't.
Anyway, go into Device Manager and find the Bluetooth settings in the tree. Open the Bluetooth settings. You will likely see several bluetooth devices, enumerators, etc. Find the one for the bluetooth controller, not the bluetooth device you want to use. It may not be clear in the wording, so look at the Property settings for each item until you find one that includes a Power or Power Management tab. Open the Power Management tab and uncheck the box authorizing the computer to turn off the bluetooth controller in order to save power. Click Save/Apply etc., and return to the desktop.
Best of luck.

Thanks, but nop - I have tried unchecking the power managment for bluetooth, wifi and the audio device itself.
I can add that now, after the latest win10 update, it seems more stable, but still not quite..
