Great, but be sure to pack a good book for the remaining 13 hours of flight time after your devices have used up their battery.

Editing comment to respond to replies in one place instead of individually.

1) The Note 4 is housed inside the Gear VR. Larger battery pack probably won't fit. You will need to carry spare batteries. Possibly the next generation might solve this.

2) I may have missed it, but I didn't see anyway to charge the Note 4 while using the Gear VR. So assuming you do have a charging port, you would need to stop and charge the device. Or carry a spare device to charge your spare battery while you use the Gear VR.

Just to be clear, I am not criticizing the Gear VR. My response was only targeted at the Parent comment's use case. I think it is really cool that Samsung is trying to think out of the box and come up with innovations. Some will stick, some won't. We will see.

The Note series has the best battery life in the smartphone game. An external battery pack is also easy to bring along.

Are there flights without charging ports nowadays?

In economy? Uhh yes. A lot.

In business class and above? Fewer.
