Battery 5 cycles, 91% capacity

Hello alltogether,
i received my macbook yesterday and used it a lot. Now on the second day, after 5 loadcycles i`ve only 91% battery capacity. Is that ok? I don`t think so. I recalibrated it with no result.

I just bought a new macbook pro 13-inch. I ran coconut battery test and it says age of the macbook is 22 weeks. And the battery load cycles shows 4 and battery capacity is 96%. Is this all normal? Does anyone have same issues?

I just bought a new macbook pro 13-inch 6 days ago. I ran coconut battery test and it says age of the macbook is 22 weeks. It shows 4 battery load cycles and battery capacity is 96%. Is this all normal? Does anyone have same issues?

"Is this all normal?"
Yes.
"Does anyone have same issues?"
What issues?
Coconut indicates an approximate battery capacity, and 96% is excellent. During testing and run-in, the MBP is charged and discharged, and a cycle count of 4 is appropriate.

Battery quitting at 30% capacity left

Same question as many below: battery quits around 30% capacity left! Not more then 1/2h of running life with only a browser window open.
Being at 133 charging cycles and less then 2 years old [replacement battery due to recall], what should I do?

my g3 also has the same problem at around 48%. i get about 4 hours on the battery. it just goes to sleep. try recalibrating the battery by letting it sleep to fully drain the battery for at least 5 hours.

2009 MacBook Pro - Battery at only 87% capacity after 5 months?

Hello,
I purchased my MacBook Pro in November. System Profiler and CoconutBattery report my battery capacity at 4756 mAh, or 87% of the initial 5450 mAh capacity. I've followed the steps to calibrate my battery twice over the past two weeks, which brought it up one percent from 86% to 87%. I've done, apparently, 82 charge cycles.
Is there a problem with my battery? I don't have AppleCare, but am assuming that a battery replacement is the kind of thing covered under warranty without it.

It is definitely on the low side for a battery in an MBP13, nusilver. These batteries are rated to 1000 cycles at 80% of original capacity (compared to SU's older model which is rated for 300 cycles at 80% capacity). My own MBP 13 , after just over 100 cycles since August last year, is still sitting on over 98%.
They may not be prepared to change it until it drops below the "official" figure of 80%, but I'd certainly take it in for testing to an Apple Store or AASP. A battery that has lost capacity at this sort of rate is likely to fail a "stress test" in which case I suspect they will replace it immediately anyway.
Cheers

What is the reasonable battery count cycle for a new macbook pro?

what is the reasonable battery count cycle for a new macbook pro? I just bought it and i found that the count cycle for the battery is 6, is that normal?

First off, a MacBook Pro is not a Power Mac. Power Mac is the nomenclature for Apple desktop machines prior to mid-2006. Mac Pros also are desktops, but later than mid-2006. http://www.apple.com/batteries/ covers Apple notebook batteries and other battery performance. I've asked this thread be moved.

I already have 590 battery cycles.80 % capacity. the MBP is only 1 year old. is this healthy? any tips?

battery cycles dont mean anything except in the old age of the battery
short term abuse kills a battery, NOT battery cycles.
General consideration of your MacBook battery
Contrary to popular myths about notebook batteries, there is protection circuitry in your Macbook and therefore you cannot ‘overcharge’ your notebook when plugged in and already fully charged.
However if you do not plan on using your notebook for several hours, turn it off (plugged in or otherwise), since you do not want your Macbook ‘both always plugged in and in sleep mode’.
A lot of battery experts call the use of Lithium-Ion cells the "80% Rule", meaning use 80% of the full charge or so, then recharge them for longer overall life. The main quantified damage done in the use of Lithium Ion batteries are instances where the internal notebook battery is “often drained very low”, this is bad general use of your notebook battery.
A person who has, for example, 300 charge cycles on their battery and is recharging at say 40% remaining of a 100% charge has a better battery condition state than, say, another person who has 300 charge cycles on their battery and is recharging at say 10-15% remaining on a 100% charge. DoD (depth of discharge) is much more important on the wear and tear on your Macbook’s battery than the count of charge cycles. There is no set “mile” or wear from a charge cycle in specific. Frequent high depth of discharge rates (draining the battery very low) on a Lithium battery will hasten the lowering of maximum battery capacity.
All batteries in any device are a consumable meant to be replaced eventually after much time, even under perfect use conditions.
If the massive amount of data that exists on lithium batteries were to be condensed into a simplex, helpful, and memorable bit of information it would be:
1. While realistically a bit impractical during normal everyday use, a lithium battery's longevity and its chemistry's health is most happy swinging back and forth between 20% and 85% charge roughly.
2. Do not purposefully drain your battery very low (10% and less), and do not keep them charged often or always high (100%).
3. Lithium batteries do not like the following:
A: Deep discharges, as meaning roughly 10% or less on a frequent basis.
B: Rapid discharges as referring to energy intensive gaming on battery on a frequent basis (in which case while gaming, if possible, do same on power rather than battery). This is a minor consideration.
C: Constant inflation, as meaning always or most often on charge, and certainly not both in sleep mode and on charge always or often.

My battery is at 516 charge cycles, charge capacity of 4129. Is it defective?

My Macbook is a late 2009 white 13" unibody model, and I understand that it should withstand up to 1000 charge cycles. I am only at 516 charge cycles, yet my battery life is dwindling, lasting approximately half as long as it did when new. I've seen it drop from lasting for five or six hours with normal use to two or three hours with normal use just in the past few months. System profiler says its full capacity is 4129 mAh; this is after I reset the SMC and calibrated the battery in an attempt to fix my problem. It charges to the indicated capacity but as I said, lasts nowhere near as long as one would expect. I remember its capacity being around 5100 when I first purchased my Macbook in April of 2010.
Obviously the laptop is out of warranty - not like it matters, since batteries aren't covered. What I was wondering is if this battery would be considered defective considering it has only lasted half as long as it "should" according to Apple's standards.

My charge cycles reflect daily use, and I can't imagine how it is excessive. I guess it might be, but I use it as I think a laptop is intended to be used. I don't leave it plugged in all day; I make use of its portablility and run it on battery at least half of the time. I usually plug it in before the battery reaches 20% as recommended by Apple, but it has on a few occasions been completely drained. I don't think my use is extraordinary.
Since posting this my laptop has fully recharged after the calibration, and its status has changed. It used to say that my battery condition was "service needed" (which is what prompted me to look at how it's been performing) but now the stats read as follows. Even the capacity changed, which is interesting. I guess recalibrating the battery removed the service warning, so I'll see how long it lasts off the battery alone over the next few days.

Battery Calibration and Charge Capacity?

I am currently using a PB G4 15" (high res DL SD) and I've had it for about a month. I just read about calibrating the battery and went ahead and did it. Have I done any damage to the battery or shortened it's effectiveness by waiting a month to calibrate rather than when it was first out of the box?
Also, i also just read about checking the battery charge capacity using the system profiler. My charge capacity prior to calibration was 2731 and after calibration it's 2930. However, it sounds like it should be in the 4400's based on the posts I've read. What do these numbers mean and do I have a faulty battery since it's so low?
Thanks for your help.

Hi Kevin --
Yeah, I'm not loving those numbers you posted either. I'd try performing the calibration procedure once or twice more to make sure that that battery capacity number doesn't change.
The other thing I would do if I were you is download Coconutbattery: http://www.versiontracker.com/dyn/moreinfo/macosx/27425
It's a free app available at versiontracker and it will tell you your battery's original capacity as well as it's current capacity.
I agree with you that a capacity of 2930 mAh after only a month of use and 16 cycles suggests that your battery is defective and should be replaced at no cost to you under the terms of the warranty.
For a frame of reference, after 10 months of use and 166 load cycles, my battery's original capacity of 4400 mAh is now 4228 mAh. No way yours should be in the 2930 mAh range.
When you call AppleCare to arrange for a replacement, if in fact that's what you end up needing to do, the agent you speak with, in addition to making sure that you've properly calibrated your battery a few times (as mentioned earlier) may also ask that you reset your PB's Power Management Unit (PMU). While I'm skeptical that a PMU reset will alter the outcome, you can find instructions on how to reset the PMU here (just in case you need to): http://docs.info.apple.com/article.html?artnum=14449
Good luck and please post back how everything turns out.

PS. You probably know this, but the calibration procedure has been changed slightly for your DL hi-res version of the PB. Here it is below, just to make sure:
PowerBook G4 (15-inch Double-Layer SD)
The battery calibration for the PowerBook G4 (15-inch Double-Layer SD) has been updated because of a new battery released with this computer. With these computers, follow these steps to calibrate your battery:
Plug in the power adapter and fully charge your PowerBook's battery until the light ring on the power adapter plug changes to green and the onscreen meter in the menu bar indicates that the battery is fully charged.
Allow the battery to rest in the fully charged state for at least two hours. You may use your computer during this time as long as the adapter is plugged in.
Disconnect the power adapter with the computer still on and start running the computer off battery power. You may use your computer during this time. When your battery gets low, you will see the low battery warning dialog on the screen.
Continue to keep your computer on until it goes to sleep. Save all your work and close all applications when the battery gets very low, before the computer goes to sleep.
Turn off the computer or allow it to sleep for five hours or more.
Connect the power adapter and leave it connected until the battery is fully charged again.
Tip: When the battery reaches "empty", the computer is forced into sleep mode. The battery actually keeps back a reserve beyond "empty", to maintain the computer in sleep for a period of time. Once the battery is truly exhausted, the computer is forced to shut down. At this point, with the safe sleep function introduced in the PowerBook G4 (15-inch Double-Layer SD) computers, the computer's memory contents have been saved to the hard drive. When power is restored, the computer returns itself to its pre-sleep state using the safe sleep image on the hard drive.

MacBook Pro /w Retina display "Battery Life Cycle"

Can the battery be changed when it reaches the end-of-life on the new MacBook Pro with Retina display? Will Apple replace the battery or the entire computer?

There are multiple sides to the answer to your question.
If the battery goes out while under warranty, Apple will fix it.
If the battery goes out after the warranty, Apple has already announced the price of the replacement. You can also check this page for more details about what is involved with servicing the batteries. For example, this page says if you can take the laptop to an Apple Retail Store you should expect a same day repair.
http://www.apple.com/support/macbookpro/service/battery/
Now the last part of the answer. Remember that the battery cycle life of the built-in batteries is much higher than for removable batteries. That's a big reason they chose to build them in, freeing up space and weight for more battery by eliminating removable-bay hardware. This means, if on the old laptops you used to replace your battery because it would run down, there is a possibility the higher-capacity built-in battery might still hold a decent charge by the time you decide that you want a newer model anyway. Meaning you might not have to replace the battery.

Macbook pro battery loss 2% of capacity after 1 week

I bought a brand new macbook pro 13" (entry level) 1 week ago. I was concerned about maximizing my battery life since I want to start fresh with this new computer. A few days ago I calibrated the battery just to make sure everything was set. I just learned how to check the battery health and charge cycles in the "About this Mac" menu, and my charge capacity is 5685 (down from the design capacity 5770), after only 5 charge cycles. Is this normal?

Hi mdudley28,
To be expected. Over the first several weeks/months of ownership, especially with an initial calibration (or two... or three) the full charge capacity will fluctuate. I've seen it bounce around by as much as 400 mAh, what's important is that it bounces back. If it continually loses mAh but never recovers and dips to sub 80% of it's original capacity then that is cause for concern and something you'd want to take up with Apple.

Battery Load-cycles help!

Ok,i got my 13" 2 weeks ago today,and im already at 22 load cycles and 98% battery capacity,but that fluctuates between 95 and 99.I Always charge it full and then let it drain and recharge and so on,should i not do this and have it plugged in alot more and not let it deplete fully?

You can find a wealth of information about Apple Batteries here: http://www.apple.com/batteries/notebooks.html
That should give you enough information to help you make the most of your battery.

Britt.

See the stuff in bold. i JUST got this machine yesterday via fedex. its a configure to order yes sure but my old CTO machine came with NO cycles on the battery and a capacity of 6900 (the design capacity of the battery)
should i file a claim against the battery? I sure feel like I should but i want further inputs.

Two cycles is really a drop in the bucket with respect to the life of your battery. I've really never made it a point to check the cycle count on my battery when I first get it. I'll usually eventually look at it when I go into the system profiler. So long as the count isn't bizarrely high for my use, I don't really worry about it. I tend to only go through a few cycles a week as I use my system primarily at home.
This is something I would definitely not get worked up about.

Battery problems - indication and capacity

Hello everyone. I have some problems with my battery:not only does it discharge in a matter of 5 hours, but also:
1)Inaccurate iOS battery indicator:iPhone shuts down with 15-20% shown, and then powers on with 10%, to proceed to shut down this time at 2-4%. Other means of battery monitoring show 5-10% less charge in the battery than the system indicator. Also, it is more accurate on wi-fi.
2)Battery capacity is at 1062 mAh! Design capacity is 1430 mAh. Has it deteriorated that much? 260 cycles on the battery. Should I replace it?
Thanks for answers

Try rebooting the iPhone by holding both the power and home buttons until the apple logo appears and it restarts, ignoring the red slider if that appears.
If this does not help the performance, take the iPhone and charger to an Apple store genius bar and have the techs run their diagnostics.

Battery reset gauge - lower capacity

Hallo,
I have question about Battery gauge reset feature.
Recently my notebook's full charge capacity drops to 80% (57Wh design capacity about 45Wh real capacity). The Power manager announce me that it is right time to perform battery gauge reset. I said ok, I will do it over night. Before I started reset I closed all applications and give it a try. In the morning I found, that the reset doesn't help at all and even drops to 38Wh (68%). To be honest I haven't been just disapointed I was angry. I used Lenovo feature to lower quality of my HW? Ok, maybe I went wrong.. I said to me. I will try it again. I restarted computer, have the background services as clean as possible and try it again. Now I have only 65% of designed capacity and wondering if there is (hopefuly) some way to get more energy to my battery. Is it possible?
My configuration.
Lenovo ThinkPad T400 - 6 battery cell (1 year old)
Windows 7 (64b)
PowerManager 3.05
Thanks for any advice or explanation.

Hi Annnastasia!
The default behavior is that the battery starts charging when it drops below 96%.
You can see this if you go to Battery Maintenance in the Power Manager.
Your T400 is new, and you shouldn't need to run a battery gauge reset.
I don't work for Lenovo. I'm a crazy volunteer!

My iPod dies!!! after the first battery charge cycle

Hi,
Last month I bought a 30GB iPod video through Amazon when I was on vacations on the US, now I'm in my hometown Lima (Peru)... well, for the month I had the iPod, everything worked fine, but I've never let the battery died, I mean I've always have it fully charged and never get the "not enougth battery message".. until yesterday when it suddenly stops playing.
Well I tough it was nothing so I turn the iPod on again and there was the Apple logo (it was the second time I saw it, the first was on the firmware update), then I get the not enough battery sign, I tougth it was ok.... then I get home, connect to the USB port I always use to synchronize it, and NOTHING happens!!!, the computer does not reconigze it, and it doesn't turn on either, there's nothing on the screen, but I did have noticed something: the iPod was hot, I immediately disconnect it from the USB (it was plugged for about 10 seconds), I've tried to reset it (procedure I've just learned since I've never had any problems with the iPod)... and no matter what i did, it didn't turn on.
I don't think the problem is the USB port because I try to connect a USB drive, and it works.
The questions is...what can I do to fix it?, I'm sure my iPod is covered by the "Apple One-Year Limited Warranty" but the problem is that I'm in Lima!! do I have to send the iPod to the US?? pleeease help me!! I save a year to be able to buy an iPod and now it isn't working!!
Thanks in advance.
AMD Athlon XP 2400+ Windows XP Pro

Thank u, Ryan, Masna and Kpxjoon...and of course I've tried the 5 R's... I think I've read every single post to find if anyone had a similar problem.. anyway
So.. Broken? how? ... well that's what I thought in first place, that I would have to send the it for service, the biggest problem is that I'm not in the US now, I bought the iPod on the US through Amazon (the shipping address was on the US too)... well now in Lima (Peru), I live here and I wouldn't return to the US anytime soon, Does the warranty still work in here??
I went to iPod Service Request site... and bad news for me again "If you cannot find the country you are looking for.... If you live outside these countries, please contact your local Apple Authorized Service Provider."
I found some Authorized Service Centers in Lima, do I have to take the iPod to them and they will fix or replace it with no charge, even though I purchase the iPod on the US??... it was my biggest worry since the beginning...
The iPod and it's package is in perfect shape, it evens has the plastic wrap, which it comes with...and I keep it in a case, so there's almost no scratches on it, and it's just a MONTH old!!!...I'm not worry about the data, 'cause everything is on my iTunes Library... I just want my iPod back
Sorry for posting so often, Thank u very much for ur time
