No, that is a slim, it has a better battery by at least an hour from what I've noticed. I also think it's better in standby mode, but I haven't honestly tested that very much. On average, you have a decent battery, but your consumption can vary depending on the games you play. For example, vita games you probably have about 5-6 hours. For other things like if you running emulators and running psp games, it might not last as long since you are running an emulator; still give about 4 hours anyway. I've used my vita quite a bit, and even after playing for a that long you can put it on standby mode and play it again for a couple of hours. It doesn't take too long to charge the vita either. There are also peripherals that extend the time played.
