1% battery charge capacity at 146 cycles

Problem started around december 2010 with macbook turning off at random percentages, generally between 70%-90%, after putting up with it a while, i took my macbook to the genius bar where he told me he couldn't see anything particularly wrong with it as far, however I should try re-calibrating. After going home and doing this, my battery info went down to about 1% charge capacity, a shocking 60 or so mAh. That's when I found this post - http://discussions.info.apple.com/message.jspa?messageID=13165866
Basically the battery update 1.3 was made for macbook pro 15" and not macbook 13"
see - http://support.apple.com/kb/HT1403
I looked and found my computer did indeed have battery update 1.3, and so, following the articles advice I deleted.. rebooted and yes my battery capacity went up to 80% not amazing, but reasonable. The battery was running through cycles fine, fully charging and running all the way down without turning off randomly for a couple weeks until... it started turning off again.
Now I've noticed the charge capacity is back to 68mAh, I've tried installing all the battery updates available, however none will install as computer says they aren't needed.
Anyone else having the same problems return? I don't know if they have anything to do with a system update which I installed a couple days ago.
macbook is well out of warranty having had it for 28 months now (bought late 2008) however 146 cycles is a bit low to warrant such a low capacity, and the fact that deleting that file fixed the problem even temporarily leads me to believe the problem isn't completely with the battery.

It really sounds like you just need a new battery. With your machine being 28 months old and having only 146 cycles on the battery, this would mean that you're going through a cycle about every two months. The cycle count accounts for only part of a battery's longevity. It's important to use the battery regularly to keep it healthy. Going through a cycle a week or so is generally reasonable usage to keep the battery healthy... even a cycle every two weeks is okay. You just need to use the battery to keep it in good shape. Going through roughly one cycle nearly every two months would seem to indicate that you ran the machine plugged in nearly all the time. That's not the best way to keep your battery healthy. Here are Apple's suggestions on maintaining your battery:

Erratic readings are not uncommon for a failing battery. The fact that it seems to work okay at times does not mean it can't be failing.

Satellite Pro L50 - poor battery charge capacity

Satellite Pro L50, I had a warning box appear from the Toshiba PC Health Monitor which said
"Your battery charge capacity is relatively poor.
After a period of time, the battery will lose its ability to perform at max capacity & may need to be replaced. This is normal for all batteries. For more info about the 'poor' charge status click the help button."
Clicking the help button indicated the battery condition at about a third charge capability.
Is this an indication that I need a new battery?
The laptop is only 4 months old & I have some concerns. Comments appreciated
Regards, Mooky.

Laptop PSKJPA-00E00U Satellite Pro L50-A O/S Win7 Pro SP1 32b purchased 22/10/2013.
1. 10/7/2014 Toshiba PC Health Monitor indicated "Battery Charge Capacity Poor - Battery will loose its ability to perform at max capacity & may need to be replaced". Battery (PA5107U-1BRS) was replaced by Toshiba as the battery is enclosed within the laptop case.
2. Currently there is a red cross on the battery charge notification icon which indicates "consider changing your battery".
This indicator is a Windows battery health warning which I have now disabled. The Toshiba PC Health Monitor indicates that the battery is good & everything is OK.
PC works fine & battery charge usually lasts about 2 hours.
Is the battery on the way out?
Do I need to contact Toshiba again as the batteries seem to last less than one year & are difficult to replace being inside the case.
I would appreciate any advice as I am unsure where to go from here.

Nominal/Original battery charge capacity of genuine batteries for 13'' macbook (mid 2007)

Hello everyone,
I just wanted to ask which is the nominal battery charge of a genuine (from Apple) battery for a 13'' macbook (mid 2007). I have just bought a new one, and it has a nominal capacity of about 5500 mAh. I just would like to check if it is in good condition.
When my old battery stopped functioning I checked some information in the web and arrived to the followings conclusions:
Webpages:
http://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batterie s
http://www.apple.com/batteries/notebooks.html
Conclusions:
- Lithium-based batteries have no memory charge effect. This means, that you don't need to be careful about charging-discharging the battery to 100% and 0% sometimes every 3 months. It also means that you can keep the battery in good health conditions not charging-discharging it at all.
- When you are not going to use your notebook for some months it is best to keep the battery at 40-50%charge (it radically increases your battery lifetime).
- It is also good to keep your battery at "low temperature" when not using it. It seems that 0-20ºC is ok. For example 40ºC is really bad for your battery.
If anyone has any comment about my "conclusions", it will be useful form me .
Thanks for the information in advance,
Jesus

Call Apple Customer Support 1-800-767-2775 (telephone numbers for other countries - http://support.apple.com/kb/HE57). Provide the serial number and specifications of the Mac. They may be able to provide a replacement set of discs for a fee. These discs will be for whatever OS was installed on the computer originally, so if you have an upgraded version you will need to obtain the discs some other way.
You may want to just upgrade to a newer system version. Snow Leopard 10.6 would be a good one for that computer but you would need to make sure it has enough RAM to run it. It would only cost $29 to get Snow Leopard from Apple and for the next 30-45 days until the next OS release in July it is still relatively up-to-date.
Get more information about your computer. Go to the Apple in the upper left corner of any window, then "About This Mac", then "More Info..." Copy and paste the information here, but omit the serial number and Hardware UUID (if present).
Snow Leopard 10.6 Technical Requirements - http://support.apple.com/kb/SP575 - note by K Shaffer - http://discussions.apple.com/message/12921514 : "Some early Intel-based Macs can't use Snow Leopard 10.6 installers; of those, the Core Duo (not 2 duo) were suspect and had issues." - and a qualifier by "a brody" http://discussions.apple.com/message/13028822 : "I think that refers to the ones without at least 1 GB of RAM."

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.

Battery Life - MacBook Pro - 403 Cycles?

I bought my MacBook pro in 2009 and we have a great relationship. It's a refurbished model so I wonder if there was something wrong with it from the beginning. I have gone through two batteris and they are both total garbage. When I unplug it, it only lasts like 15 minutes. With iStatPro, it says I have 12% health and 403 Cycles. Any suggestions for what to do? I don't really want to buy a new battery and I want to be able to use this laptop without being a desktop.
Thanks!

If your MBP has a bottom cover made up of a large back section that's screwed on and a smaller front section that is easily unlatched and removed to change the battery, its battery is expected to retain 80% health (80% of its original Full Charge Capacity) after 300 cycles if properly maintained, and beyond that all bets are off. Battery health typically falls off pretty sharply after then. If you have one of these batteries, it has given you the service it was designed to give, and you have no cause for complaint about it.
If your MBP's bottom cover is one piece, it has a built-in battery that you aren't supposed to remove yourself, and that battery is expected by Apple to retain 80% health after 1000 cycles. If you have this type of battery, it has failed prematurely, and your disappointment in it is understandable. Take it to an Apple Store and ask to have it tested for defects. If it is found to be defective, Apple may replace it free of charge. Your chances of a favorable outcome will be best if you are calm and polite. good luck!

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 Capacity after 3 cycles

Hi all,
I have a late 2013 rmbp. I've been reading up a lot on how to best treat the built in battery to maximize battery life. This laptop is only 1 week old and I've discharged once to about 40% and used the unit on batter a second time to about 50%. I'm now planning on using it on the power adapter mode when at my desk and using it on battery mode when going mobile. My question is though is that according to my coconut battery app, I'm already only at 97% max capacity! Is this normal? This battery has only been through 3 cycles of charging.
The max charge went from 6330mAh to 6153mAh in the 1 week I've owned this computer. Since I'm new to the macbook world, I was wondering if this is normal and was hoping someone could give me some insight to how fast the Max Charge capacity drops over time in relation to the Design Capacity. I'm still within my return period if I need to return this computer :/
For reference, my battery was manufactured 4/24/2014.
many thanks!

It's best not to concern yourself with this degree of detail. Over a long period of time, its maximum charge capacity will decrease. Over a shorter period of time its maximum charge capacity may decrease or increase. One week and three charge cycles is not enough to draw any conclusions about anything. Typically, the maximum capacity percentage will settle to a value in the mid - 90s and will stay there for a long time.
Your MacBook Pro's battery is the product of decades of research and is going to last for years, perhaps for as long as you own your Mac, or want to own it before it eventually becomes functionally obsolete.
All batteries are wear items that will eventually need to be replaced. Budget 50¢ a week for battery depreciation and you will have more than enough saved to replace it when the time comes.
I'm now planning on using it on the power adapter mode when at my desk and using it on battery mode when going mobile.
That's a fine strategy. Follow Apple's usage recommendations, but don't obsess over such minutia. On the other hand if you are seeking to indulge your paranoia concerning over- or under- charging your Mac, the proper methods by which you must obsess about its incessant need for proper care and pampering, and to hear admonishments about the a parade of horribles that will result in your failure to acquiesce to superstition and myth, your needs will be met in by a number of charlatans in a variety of fonts and garish colors. You will believe them because they will validate what you have already decided to be true.

Battery at 55% Capacity with 339 cycles - Acceptable?

My battery is at 55% capacity (3027mAh compared to original 5500mAh) with 339 cycles. Battery is 18 months old. Is this about normal or is my battery showing a little more wear than it should?

According to iStat, here are my stats:
Cycle count: 807
Health: 98%
Condition: Good
Full charge capacity (mAh): 4903
Yes, you read that right. 800+ cycles and still in wonderful health. She gets about 2.5 hours of hard use on battery and can still get over 4 hours without wifi & bluetooth. As a college student who uses my mac w/o it plugged in daily in class, I get at least one cycle put on it a day. Obviously it isn't truly about the "cycles" but in how you manage your use. I hardly ever turn my mac off, she sleeps at night with me. I do manage my power wisely with iStat and Fan Control. Helps me maximize the time I can pull out of the battery. I'll drain the power to under 10% every time. At least once a week, if not more, I'll let her black out on me before I resuscitate her with outlet power. Here and there, when she blacks out, I'll just close the lid and await her till morning to give her power. This will completely drain even the reserve battery. I laugh when I do this because it takes my mac about 10 to 15 minutes till she says 1%. I know I probably sound like a lunatic, but what I been doing has obviously worked, so I can't imagine it not working for you. Go crazy and drain your mac a couple times in a week and I bet you'll see a good improvement. Oh, I never leave my mac plugged in when it's at 100%... so take that for what it's worth.

Cycle count verses full charge capacity.

My battery on my mackbook says to service battery. Now I know the cycle count is high but it seems to me that the full charge capacity is only about 50%. The macbook is about 2 years old but I would have thought I could have gone longer with the battery since the charge capacity is still pretty good. So, which is better to go off of, cycle count or full charge capacity, and from looking at the specs below does it appear as though I will need to buy a new battery? Thanks..

Nonsense. The battery will actually last longer if it gets used. If it never or is seldom used, then it will die an earlier death. I see nothing wrong with what you are doing.

Does allowing the Battery to drain to 0% depletes full charge capacity?

I bought a Macbook pro 17-in intel core 2 duo 2.4Ghz from the Phiippines on July 10, 2007 and brought it to Ireland couple of days after. Later, I upgraded to leopard 10.5.2 with 4 Gig memory. Auto updates have been installed since its first use. The only problem I encountered (except for some Safari quitting unexpedtedly) was in the battery.
Here is the record of my MBP battery use:
Battery information
Battery : MBP 17in Rechargeable Battery
Model: A1189 10.18V 68Wh
Serial: 6 _ _ _ _ _ DVYF1A
My Battery practice:
- I wait for 5% remaining charge before I plug the charger
- At several occasions I forgot to plug the charger before remaining charge goes to 0%
- I usually unplug the wall charger as soon as full charge is indicated.
- I sometimes leave the wall charger plugged for several hours after green light shows.
- I use my MBP for an average of 12 - 14 hours a day. At times I dont shut it down and just allow it to go to sleep mode.
- Calibrated about 10 times.
Record of Battery Life/Charging

318 (at 3908mAh or 53% remaining charge MBP suddenly shuts down)
318 (MBP shuts down if wall charger is unplugged) Tried calibrating and resetting SMC but did not work.
I then checked if my MBP is still covered by the one-year warranty despite more than 300 battery cycles, no bulges present at apple website https://selfsolve.apple.com/GetWarranty.do (here you have to enter your MBP serial number)
I brought my MBP for check up here in Dublin, Ireland and indeed the problem was the battery. They replaced my battery with a new one without cost.
Thanks Apple my new battery now has a Battery Health of 100% with the following initial cycle records:
Battery Cycle Full Charge Capacity
1 (33% remaining charge as soon as I received it) 6810 mAh
1 (I then used the remaining charge up to 1%) 6726 mAh
1 (full charged) 6810 mAh
1 (full charged) I let it rest for few hours then checked 6879 mAh
2 (full charged) 6879 mAh
3 (full charged) 6876 mAh
4 (full charged) 6830 mAh
5 (full charged) 6845 mAh
5 (full charged) I let it rest for 1 hour then checked 6868 mAh
6 (3% remaining charge) 6829 mAh
I forgot to plug the charger (battery drained to 0%) 6492 mAh
Notice the sudden drop of full charge capacity in cycle 6? How do I recover the lost charge capacity? Does letting the battery drain to 0% depletes its full charge capacity?

The short answer is that yes, completely draining the battery has a slight negative impact on full charge capacity. The full charge capacity does fluctuate a bit over time, but the general trend is downward no matter what you do - there's a continuous chemical reaction occurring in the battery, with a finite life.
However, I note that you state +I wait for 5% remaining charge before I plug the charger+; if you are doing this because that is what you need to do, i.e. you do most of your work away from a power source, fine. But, if you are doing that because you believe that's best for your battery, that is incorrect. The 'old' NiCd batteries performed best with full discharge and full charge. The 'newer' Li-based batteries do not have this requirement, and in fact perform better over time when used frequently but 'lightly', avoiding full discharges (except for the occasional battery calibration, which allows the OS to more accurately determine the time to charge and discharge).

Full charge capacity amount on the MBP battery?

Hi all,
My MBP is only 4 months old. When I checked the batter's "Full Charge Capacity", it said 5550 mAh, which was even higher than the defult (5500mAh).
I just bought a new battery from Apple for my MBP the other day. The first day I got it, I followed the instruction to calibrate it. Then I checked its full charge capacity. It says "5450" mAh only. How is that? Why is it less the 5500?? Does that mean it has problem? I used this new batter for almost a week, it never goes to 5500 mAh....
Anyone has idea about this issue?
Thanks

UPDATE - I have found that by reducing the intensity of the display, even by a quarter, will add more than a hour to the life of the battery following a full charge. Reducing the intensity to just one quarter will give a battery life of between 4 and 4.5 hours. Putting the drive to sleep when not required extends the life to over 5 hours.
These figures are slightly better than the battery that was replaced under warranty. This suggests that their capacities are similar. I originally thought the old battery had a shorted cell, or cells, causing the battery to overheat and have a reduced capacity. I now believe I was wrong.
The Cycle Count of the new battery has reached 20 and the Full Charge Capacity 'appears' to be gradually reducing with each charge. This seems incorrect to me and I am now wondering if some kind of performance compromise has been implemented to reduce the frequency of battery failures.
I would be interested in hearing from any other forum members who has noticed anything different about the performance of the newer batteries?
I previously reported that the new battery runs cooler than the original. I have been monitoring its temperature during charging and not charging and its temperature is still gradually dropping and I am no longer suffering the 'hot lap' syndrome which I assume was because the original battery was faulty.
I imagine that the new battery requires a settling-in period so maybe the temperature will eventually stabilize. Is the charging cycle controlled by a process that can be updated? REGARDS Phil.

Since I upgraded to iOS 7.0.4 on my iPad 3, battery capacity has drained almost 10%/hour without any use of the device. Prior to the upgrade, the battery charge would hold during periods of inactivity. What can I do to solve this significant problem?

Since I upgraded to iOS 7.0.4 on my iPad 3, my battery capacity has drained almost 10% per hour without any use of the device. Prior to the upgrade, the battery charge would hold during periods of inactivity. What can I do to solve this significant problem? Is there a way to uninstall iOS 7.0.4 and return to the previous version?

Downgrading isn't supported.
You can poke around in the settings. There's a lot of stuff defaulted to on that you may not need, such as notifications.
You can also look into background app refresh and background app updates. They can be running in the background and drain your battery.

Information: Update BIOS and Battery Firmware to ensure full charge capacity

Is your system’s BIOS and battery firmware updated to the latest level?
If not, you may not be getting the maximum capacity and run time from your battery!
Lenovo’s engineering team released updated BIOS and battery firmware in July that is applicable to customers who have ThinkPad models:
X100e, L410/L510, L412/L512, SL410/SL510, T410/T410i, T510,T510i, W510 or ThinkPad Edge, 13, 14, or 15 inch units.
Customers who use Lenovo ThinkVantage Toolbox would have received a notification and opportunity to apply this update, and Lenovo’s ThinkVantage System Update tool would also identify and apply these updates.
If you aren’t using either of these tools, and have one of the systems above, please follow this link to our support site. You can learn more there, and download and install the updates specific to your system.
Probably also worth mentioning, is an earlier tip applicable to X200t and X201t tablet users who have 8 cell extended batteries. This technical tip and related BIOS updates ensure these batteries properly charge to their full capacities, and resolves a particular symptom where the battery would stop charging at less than 50%.
