Even if all else is tossed aside (the ability to turn off 3g/4g, wifi, gps, 3d, etc), I wouldn't say battery life will be a huge issue. I have two reasons for this.
1. The battery is huge. Just saying, you won't find a much larger stock battery anywhere.
2. It's not too much of a pain to plug in. Look at where you spend most of your time. For me, it's in class or at home. Regardless, I'm always pretty close to a wall outlet. You may think it's too much of a pain to carry around a charger, but don't kid yourself, because if you have a laptop, you probably plug in whenever possible. Yes, I would like this phone's battery to last longer than that of a laptop, but it DOES have some sick specs on the inside that'll suck the juice. I would have no problem keeping a charger with me all the time.
