iphone 4 & Nike+ battery life??

[Bulldog VII]

Hi all

I have an iphone 4 & use the Nike running app.

On Sunday I'm running the London Marathon (God only knows why I'm 19 stone & the same percentage of fat as a pork scratching!)

I think it will take me somewhere in the region of 6 hours.

My question is does anyone know if my battery will hold out. I'll turn off G3 & data roaming & the only app I'll have on is the Nike which uses the GPS. I'll also be using the ipod on it (got to have something to listen too for this time)

Thanks

It should last you definitely more than half the way. You could try setting the brightness all the way down but not sure if it will help much cause you'll be eating up battery with the GPS.

I have a problem with draining too but reducing brightness helped
