ok cuz i just checked and its now dropped to 93% and im like freaking out !!!
im following your plan
use the charger everyday, and then on the second or third day, just run it on battery power, until about 50% and then jack in the charger.
now my question is, if we do wait until 50%, wouldnt that end up with a no charge cycle? is this bad? because following this method, only time we would have a charge cycle is battery calibration, and times when the charger is not used...
You're saying the human body is made up of 98% water? If that's the case, you are DEF. wrong about that.
When were born we are roughly 80% and drop to around 70% and as low as 60% as we grow. Man and women are diff. as well.
Just saying
If that's not what you were saying... move along.
Thank you for correcting my biology. The percentage may be off, but my point is that just because we're made of molecules, just like a battery is, does not mean we all need the same care, in terms of water, rest, food, etc. The argument that because everything is made of molecules, that we all need rest, is fallacious.Just saying
I agree. Even water at complete rest has moving molecules... molecules above zero Kelvin are moving (thermal motion)
You know what is funny is that with the Theory of Relativity by mr einstein; its still only a part of physics and people still don't understand that we are energy and so is everything on this planet.
I should have explain it more clearly so people like you...book smart individuals can understand something so simple.
Molecules are "energy". We all know that. Energy needs to be used and to rest but also not rest for too long.
The math does hold up. It is the same reason why there is only 2-3 year contracts with cell phones and not 4 year contracts because the battery doesn't last. They jack up the prices of the batteries so people will be more inclined on buying a new cell phone. New technology.
My battery life speaks for itself. Around 900-1000 cycles my battery will be around 80%.

Humans and batteries have completely different chemical compositions and comparing a living animal, a human none-the-less, to a battery is no different than comparing a desk chair to a tyrannosaurus rex.
Actually your battery speaks on behalf of Mac's, not your battery knowledge as you said yourself you do very little to it.
The math doesn't add up except when you are armchair wrestling. In the field, variations occur and often you can not explain them.
Cell phone contracts are not 4 years because people are not willing to commit to a 4 year financial agreement for a telephone, period. The driving factor in that is the market demand and the demand for longer contracts practically does not exist. People lease houses for a year at a time, who is going to commit to a 4 year plan when you know rates will go down, phones will get better, and the entire technology will change? If you signed a 4 year contract a while ago, then you don't get to enjoy these new creations called iPhones. Also, the phone's durability comes into play. There is a lot more than meets the eye...

As does the number of cycles on your battery, indicating that you HAVE cycled your battery over 300 times. As has been stated many times, batteries need cycles, which you have been giving it, despite your claim otherwise. Your battery life is a result of healthy cycling, not as a result of "rest". Your posted battery stats have disproved your claims.
ok battery calibration day!
do we connect power adapter AFTER the 5 hours?
and also would it be bad if we "quickly" use the battery. like turn everything to high. high brightness, high backlit keyboard, etc. or should we just use it like normal use?

No. Read the calibration steps in the Battery FAQ I posted earlier.
Either way is fine.
I just calibrated my battery last night, and my battery capacity is at 5156/5770. which is 89%. Also, my laptop is about 5 months old (7 months according to coconut battery), and 92 cycles. I feel like I should start getting worried.
To add on to this, the battery capacity has been steadily falling from the start, although I've tried ignoring it, it does seem ominous. Would it be possible to get the battery replaced at this point rather than waiting for it to drop to the inevitable 80% mark? Because having that 11% more capacity makes the difference between taking a charger to class or not, so it does matter to me.

While you might get someone to make an exception, Apple usually won't replace a battery if it's still 80% or higher, unless they find something else wrong with the battery.
Everyone has to keep in mind, Apple's numbers for batteries are approximate. Sometimes you can get higher, like this, taken a few seconds ago.
This is for a Late 2008 Al MacBook that was never designed for such extensive usage. It wasn't until the built-in batteries that MacBooks got the 1000 cycle treatment guarantee.

Apple JUST replaced my battery. I bought my "classic" MBP on 10/23/08. Mine had 24x cycles (maybe 246) and my battery was at 74% at full. I had an exclamation point when I would click the battery icon in the status bar at the top. It would say "service battery".
Apple replaced it after running a test. There are two categories they fall under to determine if it will be replaced under warranty.. consumption and something else. I was stoked to get it replaced.
My computer is left on 99.4% of the time. Always is running. It is plugged in I would say 80% of the time. I calibrate it once a month or so. I dont worry about my battery. Mine lasted over 2 years (26 months to be exact). It still had life in it..
So my point is I wouldn't worry about it so much. Apple won't do much for you, as it is still at 90+ %. I took mine in when I was at 180 cycles and it held an 86% charge full, per coconut battery. They wouldn't do anything then.

You drain the battery fully, wait 5 hours and then plug it in until it is full is how I have always done it.
right but if i leave it overnight, would that hurt the calibration, because i dont think i will wake up in the middle of the night
No. If you read the battery FAQ or whatever it is that GGJ linked you to, it will say 5 hours or more. I have left my calibration going overnight before.
Cheers!
I currently dump my battery between 4 and 10 times a week. I have a little over 100 cycles and my current health (after calibration last week) sits at 99%; before it was at 94%. Battery health will fluctuate and like I said earlier, a rechargable lithium's battery life does not follow any type of linear regression.
The final step is:
It doesn't matter if you leave it plugged in overnight or 17 hours or 2 days, as long as you leave it plugged in until it's fully charged. You don't have to unplug it as soon as it's charged.
If you're referring to the step before that:
As you can see the bolded letters in the FAQ, it doesn't matter if you leave it unplugged overnight. It says 5 hours or longer. That could be 6, 11, 23, 56 hours. It doesn't matter.
The steps, as listed, are really very clear. Just read and follow the steps exactly and you won't have any problems.
