This is why the better approach is to use an app that reports about devices that are inactive. There are a few excellent ones that will give a single report once a day about all of your inactive devices. I like @ericm's Device Monitor, but [RELEASE] Device Activity Check - Get notifications for "inactive" devices and [RELEASE] Device Watchdog are also nice.
(some of those can report on battery level, too, if you want, but activity is better IMHO)
