Since I installed the latest Android security update last week, my battery life is signifigantly reduced (used to get 1.5 - 2 days). Now I'm lucky to get 24 hours.

As you can see below, Bluetooth is using significant battery. A hard boot did not solve the problem


I have also noticed that I get the following error on reboot, and I'm wondering if the battery use by Bluetooth could be related to this error.


Does anyone has any suggestions?

Thanks.

I definitely think its related. Question is, how do you fix it. You could figure out the process name and stop it and see what happens. Probably not a permanent solution though.

if you have a BT device paired try and forget and re-pair.

Actually, I would UNpair them all, if possible and leave it for half a day to a day to see what's happening then.

Also which reboot method did you use?

From BB blog: How to reset PRIV by BlackBerry | Inside BlackBerry Help Blog

Three restart/reboot methods

The first method, which should be used 99.9% of the time when you want to reboot your device, is using the Reboot option that appears after pressing the Power key.

Press and hold the Power key for 3 seconds
Select Reboot from the menu that is presented

The second reset method should be used if pressing the Power key does not produce the menu with Power Off and Restart. For example, if an app or game you are using won’t close, use this option to restart your device.

Press and hold the Power key for 12 seconds

Third method: Should your device fail to respond, the final reset method is to press and hold the Power key for 32 seconds which is equivalent to removing the battery. This should result in your device booting up successfully.

If it fails to start, however, verify you are not pressing any other keys such as Volume Up, Mute, or Volume Down while performing any of the reset methods listed above. If you use a case for your device you may want to remove it as it might be pressing a button inadvertently.

And just for an extra measure, if needed:

Safe Mode:

The next step is placing your device into safe mode.

When used, Safe Mode will disable any third party apps or games you have installed. As a result of this, should your device not exhibit the issue while in Safe Mode it’s safe to assume the issue is specific to an app or game you have installed. Safe Mode may also remove apps and/or widgets from your various home screens when you go back to Normal.

Press and hold the power key
Tap and hold Power off (that is Press/Hold the Power Off prompt line) when it appears
When prompted, tap OK to reboot to Safe Mode

To get out of Safe Mode, press and hold the power key followed by tapping Reboot.

After testing, should your device not exhibit any issues, the next step is to remove recently installed applications one by one until the issue is resolved.

All of the above, I'd do it in the following order, at one sitting.
1- "forget" all BT devices
2- 32 sec power button reset
3- go into location > 3 bar menu > scanning > make sure wifi and BT scanning are off
4- wait 30 mins
5- re-pair your most important BT device
6- run that BT device for a day
-- if all is good, repeat 5 and 6 for however many BT devices you have
-- if you find one device is causing problems, uninstall any apps that might be associated with it, "forget" that device, reboot, re-install apps, re-pair device.

Step 3 is critical, even if you don't use any BT devices

Sure would be nice if it told you which process wasn't working
