Just found this out when I went to play and left it plugged in over night. I thought this was one of the things people didn't like about the ps3 and thought I have seen them saying they will fix that with ps4 because its something they over looked on the ps3..

It has to be in standby.

@frankiebeanz: You have to set the ps4 to standby mode for it to charge when not powered up

Doesn't standby mode not exist yet?

@brich: Yes it does.

It does. When you hold the PS4 button on the controller to power down, it will ask you to turn off or go into standby mode.

Charges them fine on standby. You only should turn off your PS4 when you want to unplug it for moving etc.

yeah like the others say don't actually turn off your PS4 there's no need for that unless you're unplugging it otherwise use stand by mode, it will recharge controllers, download updates and games.

Never noticed the stand by mode right next to turn off and actually read the description?

Standy works, though I'm still hesitant to use it for a long period of time.

@brich: A ton of people were confused around this due to misremembering terminology. "Suspend/Resume" is not in right now. The only thing "Suspend/Resume" does is let you resume exactly where you left off in a game, if you go into standby in the middle. Like the Vita or PSP. Supposedly it will also work when you switch games, but that's unconfirmed.

Low powered/standby mode is live in the system. You can make it the default power off state in the PS4 settings, too.

Is standby good though? I'm kinda nervous to use it for some reason, I just been turning it off when I finish playing

isn't the PS3 always on stand by mode instead of turning off, that's why it's able to turn itself on and download patches when it needs to, so Sony has been doing it for a while you just didn't have an option, use stand by mode on PS4 it works great.

@krenor: Correct. The only way you could actually turn the PS3 off was by flipping the on/off switch on the back. Which is why so many people had issues when unplugging the power cord. They were not turning the PS3. They were unplugging it from a standby/hibernate mode.

As for standby on the PS4. I left it in this overnight while it ran some downloads. The next day the UI was very sluggish and locked up after about 20 minutes. I rebooted and it was fine. I've also set it in standby during the day for a few hours, and had the same issue. Hopefully they can patch this out. If you have to reboot after using standby its kind of pointless. It seems to me like its a memory issue. Not releasing after filling up.

Note in Europe you have to turn a checkbox in the standby settings to make USB charging work when the PS4 is in standby. In the US (maybe all other regions?) the box is on by default.

They had to comply with the laws regarding standby devices. If a device is fully powered off, there is a limit to what it is allowed to draw. Which is typically less than 1 watt these days. Hardly enough to charge. So if it were to charge controllers while powered off, it would be breaking some regulations there, hence the standby mode.
