Does that sound right so far?
Anyway, the Telegram-FOSS team claims that this doesn't _actually_ save battery:
> Despite Google's misleading warnings, there is no difference in battery usage between v4.6 in "true background" and v4.9+ with notification.
But this seems rather unlikely to me. Are they saying that an application running continuously in the background uses the same amount of battery as an application that's not running at all? Or am I just misreading that statement?
