Okay so it's common knowledge that the 3ds and vita have pretty poor battery life. 4-5 hours or whatever. But for systems that have such a similar battery life when using them, why is their standby mode battery life so different? I just checked my vita after not touching it for over 2 weeks (not plugged in), and it still had like 10% battery left. My 3ds xl doesn't even last a full day in sleep mode when it's not plugged in.

I know i can just plug in my systems each night so it's not a huge deal. I'm just curious as to why the vita can last weeks while the 3ds can't last a day. I even have my brightness turned down because i'm playing Luigi's Mansion.

Shut off the wireless on your 3DS.

How big of a difference does that make? I use the eshop alot so if it only adds on a few hours then there's no point. I'm trying to make the 3ds last days.

If wireless is on, its going to be constantly online and looking for streetpass, thus draining a lot of the battery.

Yeah, the wireless is probably the thing that drains the battery most.
Even more than the brightness and 3D.

try no to turn off wireless cause you'll end up not getting streetpasses D:
shut it off at home I guess?

Yea I know I can do that. My question was more if anyone knew why there was such a big difference in the standby time between the 3ds and vita, maybe something to do with internal components or how it actually goes to "sleep"?

It's because Vita's standby mode is a true hibernate, where the system actually saves it current state and shuts off, then restores it when you turn it back on. On 3DS, the system simply limits some of its processes, but it remains on the entire time. The latter drains batteries like 100 times as fast (on Vita, the only battery drain is the natural battery discharge that occurs over time).

I do find it very annoying as you cannot even, say, leave 3DS in sleep mode when you go to work, as it will be dead when you get home unless it's plugged in.


Incidentally DS and PSP were identical with regards to their sleep modes.

Incorrect. My Ds's all ran out of battery within a week of standby.

I can leave my PSPGo on standby for a month and have it show almost full battery.

I'm pretty sure they had the same kind of standby as their successors. The only difference is that the DS didn't have any always-on wireless features.

That's what I meant. DS did definitely last a bit longer (though I never got a whole week).
