Have a very very long flight of 12hrs coming up next week and was wondering how long will the Note 3 play movies before the battery goes down and out? I will have a mophie charger pack with me but I'm bringing like 12 movies with me to accommodate for both there and back. My iPad only has room for 2 so I'm figuring it will do for those two at which time I'll recharge my phone. I keep the brightness at about 60-75% depending on the surrroundings. Thoughts?
