My battery condition. (MBP 15, June 2009 edition).

Plugin all day at work. Use battery during the night. Just calibrate every month or so.

Vanc: Here's my June 2009 MBP (a month older than yours) which I plug in, turn off, use on battery, partially charge, never calibrate... in short, I couldn't care less about the battery.

These batteries lose capacity whether you use them or not.

Please let me know when you manage to successfully violate the laws of thermodynamics and show entropy who's really the boss.
 
I just got a MBP and calibrated the battery - came back today after being gone all day and its sitting on ac power. Battery is already at 98% sitting on the charger. Its like 3 days old, thought it was strange...

So since Ive already calibrated should I just run it down to 5-20% then recharge?

thanks-

Same with mine, only about 5 days old and it's sitting at 98% as well. Did the proper charging cycle when I first got it too.
 
Works - I ave always done this.

Mine jumped from 96% back to 99% --> 210 Cycles

I charge the mac at least 3 times day --> I usually wait till it hits 1%

Keep in mind my mac is 14 months old.
 
Not sure it's possible as batteries are a consumable. But, I appreciate everyone's attempt and posting their results.
 
Keeping it charged

Can someone confirm if it is good standard practice to keep the battery charged the whole day while working on the MBP? Is it alright to do that?

Yes, I assure you that, leaving it plugged in while using it is fine with the battery charged to 100% on a MacBook Pro.

Just recalibrate as said previously by draining comepletly until forced standby, then let it sit for about 3 hours without plugging it back in. Finally, plug it in and let it charge until full.

P.S. You can use it while it's charging back to 100% from dead; it won't affect recalibration.
 
I have a unibody 2008 MacBook (ok, not Pro), and it's at 97% health, after soon one year and 430 cycles. I am very impressed by this battery. I use the MacBook almost daily on battery, and I am not afraid of letting it go down completely to 0-1%.

I think using the battery frequently and not letting it sit at 0 or 100% too long is the way to go. And to keep it away from heat.
 
I've had my 13" MBP for 4 weeks now. Recently my battery life has gone from 100% for the first 3 weeks, down to 96% this week. I have 12 charge cycles on it, two of those from doing the whole calibration technique and mine won't improve. Any other suggestions?

Don't fuss about it. It's fine.
 
I agree with a previous poster, the obsession over Mac batteries is hilarious. Use your MacBook, use it however you want, replace the battery when needed.
 
I'm not fussing about it. I'm only concerned. I've only had it for a few weeks and now its reading on 93% remaining... 5116/5450 mAh.

The fuss and concern is the same idea. No need to be so concerned. If the battery's defective, Apple will replace it. There's no magic secret to a long life battery since it is a wearable item.

I know that, but my original post was pretty much asking for suggestions in what to do, like when I should take it in to apple. That's all I really meant by it.
 
What should the original capacity of my MacBook Pro 15" Unibody be? Coconut Battery shows it's original capacity was 4600 and it's now 4337 after 235 cycles. The original capacity of 4600 seems substantially lower than the 5500 I've read somewhere, even though it's showing health as being 94%.
 
Don't let that battery sit with 0 cycles for too much longer.

I had a one year old MBP that only had 11 cycles on the battery. Most of those were from the mag safe pulling out and me not noticing it. After one year with 11 cycles, it would not hold a charge and Apple replaced it even though it was out of warranty.

You have to use the battery or it will go bad. Four months and 0 cycles is not good.

thanks! i gave a couple cycles and one calibration.

this computer sits on my desktop and never leaves. i guess i need to unplug more often.

wow you guys are seriously obsessed about battery. Its a battery, meant to be used. Sure who doesn't like to keep it at 100%?

I like my tires to look brand new and have its treading looking the same as when I first picked it up. Its a tool meant to be used, so I'm not gonna be so obsessed that I'm not driving it just so my tires can keep its tread and looking new.

Point is, just use it and stop looking at the health unless its seriously warrants a replacement. paralysis by analysis. anyone here ever heard of it?


Finally someone that thinks like me.

Stop worrying and just use the thing. If its defective, get a new one and use it some more.
