Alright, now we are playing in my sandbox.
Of the “big three”, you have lots of options for great phones. Thankfully, all three have the iPhone now, and to me, there isn’t another option. But, I have lots of experience with Android, Windows, and every other flavor in between.
Verizon has the king Magic Kingdom app. It is like the touring plans app, several other Disney apps, and is really tied into the park. Verizon is not my employer (though my wife may work there ) but I will give them props for a great app.
My company has no Disney specific apps, but our iPhones have great access to the Verizon app and many other fantastic iPhone apps. I could go through the list for hours, there are a ton of fantastic apps for Disney. One trick with the iPhone is that you want Wifi to have the best battery life. However, if you don’t have that, such as in the park, seriously, get the Mophie Juicebox. It is a regular iPhone case with a battery built into the case. I hate carrying my phone in a case, but if I need a 2 day battery, it is the way to go.
Android phones? Still love them a lot, great apps, and some great devices with fantastic cameras, screens, and great services. They are a little more harsh with the battery to me, but you can go on Amazon.com and get larger batteries for a great price. They aren’t the best batteries, but will give you better life than average.
Windows based phones, same thing. Go on Amazon, look for other batteries.
Now, if you really need a battery miser, get a feature phone. The reduced screen abilities, the reduced web abilities, you have batteries that last for days.
Seriously, let me know what device you have, I probably have some great info. Until a few months ago, I was on the device team of one of the big three (still with same company, different role), I am sure I have access to what ever you want to know.
