Do you leave your AC power plugged in when MacBook is sleeping?

alexwei · Dec 31, 2012, 07:28 AM

Hey guys,
I'm just curious here,
How many of you are leaving your AC power plugged in to your laptop when it's sleeping?

And how many of you aren't let it plugged in??

Please share your personal experience with me.

Thanks!!!

Yup, why drain the battery when there's no reason for it.

Since my rMBP is a desktop replacement, it is plugged in (to ATD) 24/7 when we are home. Once or so a week I will disconnect the power cable to let the battery cycle down to around 50% power and then reconnect the power from ATD.

I do about the same here..

alexwei · Dec 31, 2012, 07:47 AM

Thanks guys, I was so afraid to plug it in until today and now I already have 49 cycles on my rMBP within a month.

Btw, what does ATD mean??
Sorry I'm still new here.

Ditto here.

Why? The computer has a lithium polymer battery with a chip built in, it takes care of itself. Plug it in when you can, use it on battery when you want, it doesn't matter, at all.

So long as the battery gets used once in a while, no harm will be done to it even if you leave it plugged in all the time.

Do you overthink your cell phone's charging routine as well? You probably plug it in when you can and use it on it's battery the rest of the time. The same applies here.

Depends on the situation. Sometimes yes. Sometimes no.

Try reading up at http://www.apple.com/batteries

Stop worrying and enjoy.

yusukeaoki · Dec 31, 2012, 11:13 AM

Most of the time its plugged unless I carry it around.

My MBP is 22 month old and had 92 cycles.
Which means I leaved it plugged in MOST of the time.

Prof. · Dec 31, 2012, 11:16 AM

I leave it plugged in throughout the day when it's seeping, but unplug it at night when it's sleeping inside my bag.

Run on battery whenever you need to and plug it in whenever you can. You can plug or unplug any time you need to, regardless of the charged percentage, and you never need to completely drain your battery. You don't need to run on battery all the time, if AC power is available. Just make sure you don't run on AC power exclusively, as your battery needs to be used regularly to stay healthy. The link below should answer most, if not all, of your battery/charging questions. If you haven't already done so, I highly recommend you take the time to read it.

Absolutely... I rarely turn the thing off, and it's got to charge somehow.

Another noob here and not trying to change the post, but what is a "CYCLE"

. A few of you have mentioned that word here.

After I posted this I saw another post explaining what a "Cycle" is...no need to respond.

Read the WHAT IS A CYCLE? section of the Battery FAQ in my earlier post.

And I thought I was the only one who used my rMBP this way.

Orlandoech.com · Dec 31, 2012, 02:39 PM

Sometimes, not always. No issues.

coldjeanzzz · Dec 31, 2012, 03:03 PM

I keep it plugged in all the time unless I don't want to use it at my desk. A couple of times a week I will run it down to 50% but that's it.

I'm not sure why you wouldn't want to keep it plugged in if you don't need it. Letting your battery drain for no reason is one of the least sensical things you can do with your laptop.

A Hebrew · Dec 31, 2012, 03:10 PM

I usually only keep my macbook plugged in when it needs charging. Normally that is 3 nights a week.

Thanks, but I actually don't think that much about charging my 4s.
I think the reason why I'm worried so much about the battery issue is because this machine is SO expensive and I want to take super good care of it.
