Yeah, I always leave my Vita on sleep mode.lol is the vita sleep mode that awesome? never touched one, i love my psp (got the first model still around somewhere but i know it still works) but i know the sleep mode on that thing was iffy
For people saying that sleep mode harms the battery, where is your source?
Do you turn your phone off when you're finished with it?
If you're talking stock firmware, 3DS sucks down more battery in sleep because it's actually doing cool things like Street (or Home, if you set up that sexy piece of exploit) and SpotPass. If I turned my system off like a peasant, I'd have never got Diancie. Because SpotPass informed me of that event when I wasn't exactly playing much Pokémon. And good luck with that Eon Ticket. Sleep mode is pretty pointless for most systems, unless you're in the middle of a game, because bootup times are quick. I guess if you turn wireless off...?I keep it in sleep mode and the battery always dies after two days because I forgot to charge it.
I wish sleep mode was as good as PSP.
