How long does the battery on my iPhone 5c last?

So I'm going on a trip on an airplane in a few days. When on the plane I'm gonna have it in airplane and listening music. Will my battery last all 7 hours of the trip?!

IPhone has good batteries so I'm sure it'll last. Airplanes usually have USB socket so you can charge your phone. Buy a power bank if you think you need more power.

I doubt it, buy a portable charger just in case. It's a block type of thing and you charge it at home and then when you leave somewhere you just plug your phone into it and

When in airplane mode, it does help conserve the battery but I do not know that it will last seven hours. Have you considered a power bank? You charge it and then it can be used to charge your phone. I'm going on an international trip soon and have one for that purpose.

Some seats (not all) have power capabilities, so take your charging cord (usually it is USB).

If you'll be using it for music for the whole flight, or even most of the flight, it will probably not last. I agree with getting a portable charger. Some planes used on long-haul flights do have charging ports, but I wouldn't count on it, especially in economy.
