@pBoelck There is a fix available for this in the latest release. Please upgrade, and set the config flag config.batterySaverEnabled = false, which will prevent Tealium from registering for the low power notification. Unfortunately this is the only solution until Apple fixes the bug in iOS 15.

Thank you for the timely response. 👍

@pBoelck You're very welcome. Please note that we've been unable to reproduce the crash in our testing, but we are confident the fix should work, as it avoids us registering for the notification at all.

@craigrouse We have been unable to reproduce the crash too.
Hopefully apple will fix the problem soon.

@craigrouse
One last question from my side.
The version 2.4.4 has the config setting config.batterySaverEnabled = false.

Is it still necessary to update to 2.4.6?

[craigrouse]

@pBoelck yes - previously we still registered for the notification even with this setting set to false. Now we only register if it's set to true, so having it set to false should prevent the crash, but only in the latest release.
