You’ll lose about a half a percent per hour, so if you’re leaving it off for more than a day, it’s best to shut it completely down.

It's horrible about sleeping. If you want your battery, turn it off. The latest update seems to be better, but I wouldn't trust it in your shoes.

Anecdotally it seems to have a similar drain rate to my laptop, around 10% a day in sleep (though I would recommend actually verifying this yourself to be sure). So if you want to conserve battery life, turning it off is the way to go

While it will lose 10 percent per day, being able press the button and continue playing is one of major factors for me. But it's almost always on the charger if I'm not playing and charging limit is set to 80% to preserve battery.

I don't power it off.

Then again I only let it sleep a couple hours at a time at most, since I know I'm using it again soon. It's not like you lose half the battery by doing that, and the whole point of the fast suspend and resume is so you can stop and go while on the go.

If I'm leaving it overnight, then I power off.

I play mine enough that I never turn it off. I usually play multiple short sessions throughout the day, so having instant suspend/resume from the middle of the game is much more important to me than the minor battery drain.

I'd only turn it off if I didn't expect to play it for a few days, but even then I would probably just stick it on my dock in sleep mode, and trust pass-through charging to keep the battery healthy.

Personally the only time I turn it off is if I am putting it in the case. Even then if it's just a 15 minute car ride to a friend's house I might just leave it on.

It's also rare for me to go more than 2 days without playing it, and I mostly play around my house where I have USB cables around to plug it in if need be, so battery isn't a huge concern. In fact I usually have the battery saving feature set to limit it to 80% charge.

The only reason I really turn it off in the case is our if heat concerns, and I suspect that'a just me being over protective. I guess the other thing is that there could be security and privacy concerns from carrying around a device with WiFi and/or Bluetooth on.

Yes. I usually leave whatever game I’m playing on, running, on sleep mode. It’s always fine. I do however, make sure that the fan is not blocked off, and that it’s plugged in so I don’t wake up to a dead deck. Otherwise, there isn’t any danger that I’ve noticed- everything runs fine. If you’re NOT running anything and put it in sleep mode, any percentage above 15% should be fine. Turning it on and off actually takes more energy than sleeping it does, so I’d just keep doing what you’re doing.
