Bluetooth Battery Drain

[Xocnai]

I've searched high and low for information on this, but to no avail.

I experience heightened (2x-3x) battery drain when bluetooth is enabled, even with scanning disabled.

Ordinarily, my XZ1C would pair with my Fitbit Charge 2 and/or my car (UK Fiesta 2017). Even when away from my car, and with all day sync and notifications disabled on the fitbit app, bluetooth is causing a wakelock, which in turn is causing drain on the battery.

Currently, my only solution is to keep BT off which cripples some of the functionality of my phone, particularly pushing notifications to my fitbit.

Has anyone else experienced this drain/wakelock with BT enabled?

I've been through a full repair and reset, but no cigar.

I could run in safe mode, or strip all my apps, or not connect to my car or fitbit, but frankly I shouldn't have to go to such ridiculous lengths. Something is not working as it ought to.

The daming factor is I'm seeing worse performance with BT enabled in the same usage scenarios as I had with my Samsung S7E, which was frankly pretty appalling as far as battery life goes.

Pretty unhappy with the situation. Either I disable BT and have great battery life, but I can't use the functions I find most valuable in a handset, or I use those functions and battery life goes down the toilet. Great...

Any official response on this issue? It seems to be quite common across multiple forums on devices with Android 7.1.1

Having the same issue even after software repair/factory reset.

I have an X Compact with Android 8.0, and I have BT switched on at all times. I make extensive use of the BT connection with car audio and headsets. I don't see any particular drain associated with having BT active.

Perhaps this is more of an issue where the smartwatches and data-driven peripherals are concerned. Sounds like once such a device is paired and is active, a BT data channel is kept open and active whether or not data is actually being exchanged. Akin to the phone constantly searching for new BT devices to pair with. (Just a guess)
