How long does your device usually last on Classic?

Make sure you tell me the Device name, OS, and screen brightness (that isn't compulsorily).

I'm curious to know which devices (excluding PC, sorry guys) last the longest playing Classic, the all mighty drainer.  

iPad 3, IOS 8, probably around 10 - 11 hours if I left it on constantly.

EDIT: Minimum - 20% brightness  

ipad 2
Screen brightness lowest
About 7-9 Hours or more
Ios 6  

O seems like brightness helps a lot. You guys have any medium brightness data, or do you just play in the dark all the time? Lol  

Played in the dark mostly, wont even change brightness when real life brightness changes  

Ya real life brightness is horrible  

Two thing effect the battery life a lot, brightness and location service. my iPad 2 with iOS 8 lasts up to 10 hours on constant playing with moody-medium brightness and location service on, and up to 15 with location service off.  

Apps in the background while playing Classic can also make the battery get low quick. I'm on iPhone 5S (iOS 8), Screen brightness: 50%, usually runs for about 3-6 hours.  

my ol ipod 4 doesn't last long before it succumbs and turns off c.c

max is probably around 3 hours if im lucky, however with this being said i rarely play classic nowadays anyway.  

My iPad isna powerhouse, I could play from 8 pm to 2pm straight
