I was on a flight recently and the lady next to me had a large Samsung phone on which she was constantly playing games, etc. and I was very worried.

I was also afraid of questioning if it was a Samsung Galaxy Note 7 because the attendant made an announcement saying people should turn it off and she didn't. Next time I'm not going to be afraid. Can't imagine the consequence if it caught fire at 30,000 feet.

A burned hole in the carpet.

I'm much more worried about something like this in a check-in bag, where the fire can spread uncontrollably. At least in cabin you will notice the fire early and can use the fire extinguisher.

A fire extinguisher is not going to do much against a lithium fire. But at the same time, such fire would end before you even got up from your seat - the only concern would be something inside the plane catching fire, but literally everything inside the cabin is fireproof.

Fire inside the hold is another matter entirely, but there are fire suppression systems fitted into all planes nowadays.

I don't think lithium batteries are allowed in check luggage. You're supposed to carry them on.

Thank God everyone carefully reads and follows the checked luggage rules and regulations! ;)

I believe it's batteries on their own - as long as they are in a device I believe it's fine (if not I've been breaking the law...).
