Eh, once the extra Circle Pad Pro comes out, the 3DS will have 400 plus hours battery life.

Least I'm hoping it's not a just a rumor.

Edit:, Hmm, now that I read it again, it looks like the Pad itself will get that battery power, not the 3DS, my bad.

Great I'm gonna have to keep my Vita tethered to the wall along with my 3DS

No fair!  The phone cheated!!

to be honest, i've never had an issue with the battery life on my 3DS. i've left it in sleep mode all day countless times, and the most its ever gone down is one bar. And i've only had it gone red on me while i was playing twice. At least in my experience, the life of the batter (or lack thereof) has been greatly overexaggerated. I expect the same of the Vita, but seeing as how the Vita doesn't have any sleep features like streetpass and spotpass (if it does, feel free to correct me), i might even get more out of the battery. TLDR: I've never had an issue with battery life.

Battery is life is very important when you're not by something you can charge your handheld with, if you're just in you're house, its no biggy, I always leave my 3D switch off it strains my eyes and I just don't like it

That's just sad, 3DS. The battery life for the Vita isn't all that great either, but at least it's dishing out near PS3 quality visuals. As far as the PSP goes - it had a decent battery life given the how big the screen is and overall graphics. I never really go to far away places, even then, I don't play my handhelds on the go that often.

To be honest in my case it doesn't matter. I rarely take my handheld outside so in that sense it does not bother me. With that said the 3DS would definitely benefit from a better battery for those long gaming sessions.

like how th oldest system held up the longest. Long live psp, may your heir do better than you did (commercially). I still love my psp, and I remember when it was big deal awhile back ago.

Three hours for the vita seems good not too much but i can deal with it.

I do most of my handheld playing on Plug Power personally, but I can easily understand how important Battery Power is to those that need their handhelds on the go a whole lot more than me.

this is a shame. with all the money companies make, you'd think they'd invest more into making stuff last longer, as is the case with the battery life. despite all the features the vita offers, its terrible that its battery life is half of what you'd get out of the regular psp. its not just gaming, but also with phones. if you put an older model blackberry up against a new iphone or android phone with full charged batteries and leave them with no software running, the blackberry will win. it makes no sense how something old lasts longer than something that just came out.

I keep my 3DS on 24/7 and I have only once had battery issues. As long as you set it on the cradle every so often. I really don't see what everyone's issue is.

On an unrelated note, chiptune remix of FFXIII's battle theme? I like. Very much.

i do not leave my 3d on my 3DS at all times. the first thing i turn off is the wireless when im not using it and i keep the brightness between 1 and 3. when i get to red light i drop everything to the lowest possible setting and when the 3DS starts blinking it still lasts for about 30mins. DS Lite still has the best battery life out of all the systems

In today's world most people aren't really focused on battery life anymore. At cafe's, resturaunt, some airplanes, cars, and even some stores have plug ins for outlets these days. Though a 3 hour battery life is on the low side, it's still better than playing on double A batteries like on the gameboy systems and most console controllers. I really don't see too big of an issue over something as simple as battery life for something that you can bring everywhere with you while being able to charge it at 75%+ of the places you see or go.

I think the PSV will be awesome. Better then the 3DS, TBH.

Really? My 3DS can easily run 5 hours with the 3D all the way up from full power.

You think with all the advanced technology they'd be able to improve battery life...

man, does vita at least allow for replaceable batteries? I might wanna invest in a couple
