another +1 to only being on the charger when charging. My 2010 MBP had 1300+ cycles on it and it still lasted 5-6 hours on a full charge
 
I'm just wondering because is it a bad idea to run the battery down to like 10% and then plugging in as needed?

What is better for the battery, to keep it plugged or let it drain to a certain % and than plug it?

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. 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.
 
Why do people question the reason some purchased macbooks because their macbooks are almost always plugged in? It's funny that one would say if you wanted to keep your mac plugged in, get an iMac.

As if the only reason someone buys a mac is so they can brag about how long they can surf the net with one charge. The again, people brag about the oddest things here.

If I'm at my desk and choose to keep it charged because I know I have several hours in meetings away from my desk, why not? Why drain the battery and then have to carry a brick around or wonder if my battery would last. I know I'm going to spend a few hours on the plane/airport - why drain my battery at my desk?

I buy a mac to use it the way that suits me - not checking battery life, mulling over internal temperature, or carrying it around in a padded tomb after sealing it in a condom just so it can be resold for $5 more in a few years.

This made me lol. :p Totally agree with the above.

Mine is plugged in 90% of the time. For that 10% or so when I want to use the laptop somewhere, other than on my desk, the portability is there. Hence, why I ended up selling my Mac Mini for this very reason - lack of portability.

What you describe is actually ideal usage: a mix of running on AC and also on battery.

Yeah, I don't see a big deal. I certainly wouldn't get an iMac, because there are times when I need to be portable. But unless you are using it on a couch or dinner table or something, it makes complete sense to have it plugged in during usage.
 
I have used Mac laptops for nearly 11 years, a 17 inch PowerBook G4, followed by a late 2007 17 inch MBP, and by a 2010 13 inch MBA. I have always kept my Macs plugged in most of the time and will no doubt do the same when I upgrade to either one of the new 13 inch MBPr machines or to a new MBA.
 
My 15" is my desktop at home. And when I go out it's my laptop.
 
I take it to class a few times a week. Keep it plugged in at home mostly because i am already plugging in a USB hub, hdmi, VGA and headphones.
 
I like keeping it plugged in while at home, while traveling on the battery, when I reach my destination back to being plugged.
 
It absolutely does not. Where did you get such an idea?

This is correct as GGJstudios said above. One can lower the screen lighting, and such to increase battery life, but one can crank up the works as well. Processor will perform either way.
 
how good are these batteries on the rMBPs? The one from my late 2008 MB got all swollen. Luckily I can swap it in like 20 seconds. These however are glued down.

They're fine. I fully expect to get the full 1000 cycles out of mine and a good few more besides before I need to replace the battery.
 
So you're telling me that the macbook doesn't throttle on battery to save power? :roll eyes:

it does.

It absolutely does not. Where did you get such an idea?

Thought I'd settle this, so I carried out an experiment.

I ran GeekBench first with the laptop being powered by the adaptor, then waited for it to cool back down and the fans to go back to normal speed.

Then I unplugged the magsafe and ran the same test on battery power.

The results are attached.

As you can see, the results are close enough to each other to conclude there is no throttling.

For some users it's the other way around (counterintuitive as it may sound,) ie throttling occurs when mac is plugged in.
 
You guys should've gotten iMacs lol.

I'm on the go most of the time. Class, girlfriend's apartment, a coffee shop or just taking it with me to work. I'll be taking it with me to Japan when I move and I fully intend on taking it with me to shops and such.

I bought a MacBook so I could carry it around and use it as a mobile. Using it as a desktop? *purpose defeated*

I'd say I use it while plugged maybe 20% of the time. If I'm working at my desk or at a study lounge with plugs. But 80% of the time, I'm cycling it.

Agreed. I have mine plugged in id say 50% of the time. I love the freedom of being able to use a computer anywhere in the home or anywhere I go. I don't even think id ever want a desktop again now.

Its also like the people who own convertibles but never put the top down. I hate that. Buy a normal car then. I have a vert and the top is down every time it is 60+ degrees and sunny.

Throttling has nothing to do with whether or not a Mac is plugged in or running on battery. Throttling can occur if temperatures get too high, but that has nothing to do with the plugged/unplugged state.
 
plugged in 95% of the time...300 cycles, 1 year, 92% capacity. Doesn't hurt your battery =p

If only what you said were true.. *sigh*

I said what I said out of first-hand experience. And there're threads on mac boards (some lying about on this one) about people exhibiting similar problems (2012 rMBP)

I've since found a workaround. I might post a thread about it later.

Provide evidence, if you can. You can't, because Macs have never throttled based on being plugged in or being on battery power.

The only scenario remotely close to that was with older Mac portables with removable batteries. If you ran on AC power with the battery removed, the system would throttle, but that is a completely different scenario that obviously no longer applies to Mac portables, as they all have built-in batteries that can't be removed. This scenario is described in the AC POWER section of the Battery FAQ I posted earlier.
 
On my machine (2012 rMBP) when benchmarking using geekbench (which focuses on cpu benchmarking) here are the results with the power brick plugged in and with battery use only:


plugged in

No throttling exhibited as you can see.




Games and apps that stress the dGPU on the other hand paint an entirely different picture:


plugged in

Major performance hit when plugged in as evidenced by the results. I don't need to rely on numbers to convince myself that it throttles when plugged in,, as stuttering would occur moments after starting a game while the laptop is plugged in, something that rarely if ever happens while running on battery alone.


I choose my words carefully. I didn't say on some machines for no reason. You may not have encountered this behavior, but that doesn't mean it doesn't exist on some macbooks because of hardware limitations or issues.
