Well, if save mode is not available on the device, there's not much we can do :)

inInBatterySaveMode returns a bool, so we cannot return a different state (like unavailable).

Probably improving documentation and explaining that the method will throw is good enough.

Still, is good practice to catch all errors that can come from native platform calls just in case.

Can you please reopen the issue? This happens on a Huawei P30 Lite which has a battery save mode, so this shouldn't throw an exception.
