Boeing has recommended that carriers do not carry Lithium batteries in their holds. It will be upto the profit seeking carriers whether they comply with this recommendation.
I have a Galaxy S4 mini. It too gets hot, and sometimes for no discernable reason and drains the battery like a drunk in a bar getting free drinks.
Even when the Phone's Wifi/ GPS are turned off, and all apps closed, it will do so. Usually rebooting the phone stops this excessive mysto battery drain. Sometimes putting it in airplane mode stops the excessive battery drain, other times not.
Invariably, this is some sort of Wifi search function gone haywire and draining your batteries, or a cell tower search function gone haywire, searching for a cell site. Pumping out pings and broadcasting packets at full wattage in search mode draws a lot of current from the batteries. Try turning off data mode and wifi mode temporarily to clear that stuff out, or reboot the phone.
