New MBPro - 96% Battery Health - only 70 minutes of working time

I have a late 2008 MBP 2.8Hhz Core2Duo. My battery's health is listed at 96%, with 29 cycles.
When I use it without the power supply I literally can work for only **40 minutes** before I get the red time warning. In total, I get maybe 70 minutes off the power supply before it conks out.
This is pretty bad performance with a health rating of 96% and with only 26 cycles.
Has anyone else had it this bad? I paid so much for this computer....
Don't know what to do.

I should also note that whenever I click on a message on the OSX Mail window the CPU usage for Mail goes from almost zero to 80%, the computer's fans start going crazy, and the machine starts to lag and beachball at intervals.....
So OSX and Safari are ruining my computer experience.... Makes no sense as they are prominent Apple offerings

Only 52 cycles and battery health dipping to 73% at times?

My macbook pro is less then a year old and I lately have been having strange battery health readings. The battery usually lasts a few hours depending on what I am doing with it unplugged. However the health twice now has dipped to 73% and then jumped back up to 89% or 91% and stayed there. Today I checked my battery condition and it said "check battery" but then went back to "good" later that day. I condition the battery regularly.
Here are my specs:

It's normal for health to fluctuate a bit (mine ranges from 86-96%, and has done that for the past 100 cycles or so). But, your fluctuations are a bit wider than I'd consider normal. Keep an eye on it, and if it dips and stays below 80%, contact Apple before your 1 year warranty expires.
When was the last time you calibrated your battery? That should be done every 2 months or so.

Brand new macbook pro 2012 (no retina display) 95% battery health with 5 cycles? is that okay?

I know, another battery related question. I have recently bought a brand new macbook pro (no retina display), I calibrated the battery at least twice since Ive had it and it states that I am at 95% battery health with only 5 charges. Is that normal or should I bring my macbook in to be checked? Id like to get this settled before school starts in September since I depend on my macbook a great deal.
thanks !

Full cycle? 100%, of course.
How you get there is another matter. It can be a battery killing full discharge that will certainly ensure a brief life. Or a leisure set of discharges down to 20%, 30% or more. When they all sum up 100%, winner! You've got a cycle!!
Apple recommends you enjoy your Mac and don't obsess too much on battery stuff. Just exercise the electrons every so often by bringing it down to, say, 20% and charge it back up. Going all the way down to the bitter end, when the Mac forces itself to sleep is sort of ok too and won't do (too much) damage, provided you don't make it an engrained habit. We all forget the power brick occasionally and get caught out in the wild with whatever charge was left inside.

Battery health=40% time for a new battery?

So from tiger cache cleaner I got the following information
capacity=1773 mAh
cycle count = 327
current capacity= 1770mAh
voltage= 16466mV
absoluteMaxCapacity=4400 mAh
Battery charge= 99%
Battery Health=40%
My ibook g4 1.2ghz is about 16 months old and has been used everyday. I have frequently left it on and have plugged it in when it is low or out of batteries.
Recently for about the past 3 weeks, while showing a full or 60% charge, my ibook will shut down at random. When I start it up again, it will stay on for 10 to 20 minutes unplugged before it shuts off again. When plugged in it works fine. I have not tried a new battery, I have not reset the PMU (it said all Ram disks will be permenently erased?) and it will not let me calibrate the battery because it will not stay on long enough to drain it. When I push the batteries button I get two green lights out of four.
is it time for a new battery? Is says I have done 327 cycles.
thanks for all the help.

It's supposed to keep 80% capacity after 300 charge cycles.
A PMU reset is in order:
http://docs.info.apple.com/article.html?artnum=2238
Don't worry about a RAM disk. You have to have created one in order for there to be one to be erased. If you don't know what one is, you don't have one.
Try resetting the PMU and see if that will allow you to calibrate the battery.
If things still aren't working right, a new battery is probably in order.

Battery health is 78%, 479 cycles, 3 year old Macbook Pro 13" 2010. Time to purchase new battery?

I have a 2010 13" Macbook Pro that has a battery that constantly remains at about 78% of the original capacity. I have gone through 479 cycles and I only recharge when the battery is less than 10%. It doesn't matter what I do because it always remains around this range of health. What should I do? Should I purchase a new battery?

why not just use your macbook as it is until the service battery messages shows up.
i have 2010 Macbook Pro with 913 cycle count - 84% Battery Health and I still get almost 5 hours of normal use.
See image below.

A1281 is the battery i got for my 15inch MBP. Is the battery life only 2 - 3 hours for a new battery on this device.

A1281 is the battery i got for my 15inch MBP. Is the battery life only 2 - 3 hours for a new battery on this device.
This is from Apple.
2 to 3 hours seems very low.
what is teh standard or advertised spec for a 15 inch Macbook Pro with this battery.
I would like to know so that i can return it if this is not normal.
Its expensive so comments would be appreciated.

I say it depends on your model? average usage is about 3-4 hours depending on what you use and how you use it. Adobe Flash player eats a lot of battery power so if you are on a web page and has flash player, likely that it's eating up battery because of it's power thirsty.
Also check your systems activity monitor. It could be possible that one of your program/apps did not close right and may be still running. So check for that and end the process if necessary.
If you have a backlight keyboard, in a broad daylight, it's not necessary to have it on.
I also suggest that you use it plugged in most of the time, and it's not going to hurt or damage the battery if you have it plugged in all the time. Only use on battery if you are going to places that has no access to the outlet. If you are at home, then keep it plugged in. Just keep in mind to fully drain the battery until it your MBP turns off on it's own. This is the calibration process so that you have the most accurate battery readings.
The standard for 2011 MBP is 7 hours on battery. Before that model is 10 hours, but i don't believe that previous models will last 10 hours. Last week I calibrated my battery readings from fully charged and it took 9 hours to completely drain out the battery (I have a 2011 model),
If you think it's not normal and that your battery doesn't meet your expectation then set up an appointment with the genius bar and have them test the battery. They will determine whether it is faulty or not.

New Mid-2013 Macbook Air Battery Health issues

Hi,
I bought a new Macbook Air 13" 128GB 4GB RAM for 2weeks. I discovered that the battery went much fast than I thought. Now after 2weeks, the battery heath is decreased to 97% and cycles 21. And a fully-charged battery last only 7-8hours. Besides, the back of it come always too hot. What should I do to fix this issue? Thank you!!

Anyone can help please??

Why does my iPad Mini Retina Display battery drain so quickly? I will be playing some 3d games and it says the battery is 90% but I'll turn off and turn in back on it about 30 minutes and the battery is only 70%. Why is the reading so inaccurate?

I will be playing some 3d games and it says the battery is 90% but I'll turn off and turn in back on it about 30 minutes and the battery is only 70%. Why is the reading so inaccurate? I understand that 3d games on high brightness will drain my battery quickly, but why doesn't it tell be how low it is to begin with? The other night it said it was around 35% and I turned it on in the morning and it was only 3%?

Sorry there are some typos above, but you should be able to figure out what I'm asking. Let me know if you have tha same problem, know how to fix it, or know if apple is aware of the problem and is adressing it in a future update.

New Macbook Pro 2012 Battery health.

Hi all, hope you can give me some advice.
I purchased a New Macbook Pro 13" (2012 model) 3 weeks ago. It has now had 11 charge cycles and the battery health has dropped to 86%. I have gone through the calibration process, reset smc/pram but sitll seems to be dropping.
Is this normal, should i return it to apple and have the machine swapped, should i just leave it and if it gets worse get it repaired under apple care.
Intrestingly, Battery health states the battery is 9.3 months old, from the serial number of the mac I understand that that mac was made in 3rd week of october, I just wonder if that battery has been stood arround semi-charged for 9 months and this has damaged it.
Any help would be great, thanks
Paul

I would make an appointment at your local Apple Store or an AASP and have them test the battery. My battery 'life' is right on the manufacturing week of my computer. Something's up with the battery - since you're still under warranty have it checked out now.
Good luck,
Clinton

New MacBook Pro 2012 with battery health at 92%

Hi everyone!
Few weeks ago I bought brand new MacBook Pro (2012, 13"). After 12 cycles the battery health significantly decreased to 92%. Quite unexpected, isn't? Could you advise me what can be a problem? AC adapter, socket in my wall or something else?
To answer your questions, I did not put the battery below 10% during this time.
Thanks in advance for any hints!

You have to take the computer to the Apple store to have it checked out.

New MacBook Pro but Battery Health 97%?

I recently bought a MacBook Pro 13inch just last thursday and I came to notice in the iStat Pro Battery Info the Battery Health is 97%. Is this normal? Number of Cyles are 7.

Be aware that "health" cn be "current charge" or "max possible charge".
As Steve Ar said, both can vary a bit.
My MBP (see attached image from Cononut Battery Monitor,
This can be downloaded from macupdate.com)
My MBP has been powered constantly for the last few day, but has dropped to 95%. It does this to prevent the "constant use" of the recharge circuits, and will recharge itself to 100% when it drops below 95%. Also the max charge is more than design, but will not stay at that max charge ... it will change a litlle even rising fromover 7000 mAh occasionally.
To keep your battery healthy, do NOT run it dead. That kills LithiumIon batteries. You need to exercise those LithiumIons sometimes or they get fat and lazy. Use the system on battery only at least once a month, down to 50% or 60% and then recharge.
Also note that the life-limit of LI batteries is about 1000 cycles (each full charge is 1 cycle, 2 charges from 50% to 100% is 1 cycle, etc). It can exceed that, but the closer yo get to 1000 to more likely it is to need replacing.

Indicated battery life in new MBPro 15

Day 1 of my brand new MBPro 15... 5400rpm drives. Just off the wall power and sitting on my couch with battery already on 88% and 2:12 remaining. From everything I've read that is extremely low for this early in the game.
Was reading on line... do I need to reset the SMC?
Is it consuming too quickly or is the indicator incorrect?
Thanks for any help you can give me!

My MBPro 15" i7 thinks it runs on nuclear batteries, I think. See the screen shot I recently took after opening it up on the train and working for a while then seeing the battery indicator.
It eventually came down to 7-odd hours then reduced in the normal way.
It certainly seems to last though. The link was useful thank you and I shall remember that. I've been turning Skype off a lot lately to save memory as the Apple Tech guys always say it consumes a lot of memory. As I use Aperture 3 this can be important.

New Macbook Pro Retina 15inch is showing up as 1.9months old with 2 cycles on 'Battery Health'!?

Hi,
I've just recieved my New Macbook Pro Retina 15inch and installed 'Battery Health', but for some reason it is is showing my Macbook as 1.9months old with 2 cycles!? This Macbook isn't even a day old.. Is this normal!?
Please advise..
Thanks,
P

That is not unusual. Note that the actual maximum charge is well above the designed level which is the most important criteria.
Ciao.

How to increase your battery health - anyone with similar experiences?

this is my very own self made instruction of "how to increase your battery health"
it is the procedure how i have done it serverall times on my powerbook g4 12".
my stats: 374 cycles, health 86% (3790 of 4400mAh)
age of my mac: 57month (battery bit newer)
**if you to try this: it is on your own risk!**
**this may not be suitable for mac newbies**
**be sure to read this twice before you do it once!**
you will need:
-a pocket lamp or comparable light (to see anything on your sreen when it is dark --> light from the back through apple logo)
-coconutbattery (coconut-flavour.com/coconutbattery) or comparable programm to track your battery information in realtime
-activity monitor
-cool enviroment (to ensure your fans don't have to work that much)
-some time and patience
the intructions:
step1: load your mac until the orange light turns green
step2: disconnect the power adapter
step3: use your mac until 15-25% battery life (track this information in your menu bar)
step4: slow down your activities. the order of the following actions depend on your usage of your mac:
__close programms that use lots of cpu/gpu to ensure the fans slow down to 0rpm (!!)
__turn off everything that needs battery power: airport / bluetooth / speakers / etc.
__eject dvd or cd
__close all programms with important data
__eject idisk / .dmg files in your finder (this is not only a matter of data security)
__dissonnected from peripherals such as ethernet / internet / mouse / keyboard
__use lower brightness level
__open activity monitor to ensure that your hard drive activity is very low, may be you need to close more active programms, close activity monitor when hard drive activity is very low
__open system preferences >> energy saver preferences >> choose longest battery life
when your are ready with those actions go on and ensure you are able to connect to power adapter with your mac quickly (be able to charge - don't do it yet!)
step5: be patient. now it should take some time until your battery level goes down to 3-5%
now there should be no programm running.
do not open any programm now!
do not have a look at your dashboard!
now your mac should be really quiet:
-no fans (0rpm!)
-nearly no hard drive activity!!
-->> if this not the case break go on with step 11&12, try again in a week or two
-->> if you are ready go on with step6
step6: open coconutbattery und use the lowest brightness level
play with your trackpad to ensure your screensaver won't start. waste time until you are at 1-2% battery life.
step7: take your lamp and spot through the transperent apple logo, position your coconut battery window somehow that you can see the current battery charge und the maxium battery charge in the spot of your lamp through the apple logo.
step8: go from the lowest brightness level to the level under the lowest brightness level (a dark screen)
step9: watch your current battery charge carefully und keep on playing with your trackpad to ensure your screensaver won't start.
step10: there is kind of battery buffer made of approximately 1% (once when my "current battery charge" was 3624mAh and this kind of buffer was at 36mAh)
to empty this kind of battery buffer takes much longer as you might expect!
when your current battery charge turns under this kind of battery buffer, your maximum battery charge should change. hopefully it is higher or stays the same. when it is lower now: i'm sorry - i have warned you. may be you have to go through this 'how to' more carefully!?
step11: plug in your power adapter before the battery is cero!
step12: load until the orange light turns green
step13: if it was helpful do not repeat it more than once a week, better once a month

(via: http://www.apple.com/batteries/notebooks.html)
anyone with similar experiences about increasing battery health!?
(yes, i'm sorry for my poor english, i've tried my best)

Me too! My battery lasts for 10 minutes. It is awful and I am on my 4th power adapter since they keep breaking too.
From coconut battery: Maximum battery charge 310mah, original 4400, age of mac 45 months, 140 cycles.
From system profile:
Battery Installed: Yes
First low level warning: No
Full Charge Capacity (mAh): 310
Remaining Capacity (mAh): 213

I went to an apple authorized retailer and they said nothing I can do if it is out of warranty.. is this true?

My MacBook Air's battery health is decreasing.

My Macbook Air's battery health is decreasing. I bought it around a year ago. Now it's battery health is 85%. However, it keeps changing. From 85% to 88% and sometimes it hit 90%. Is my macbook's battery healthy? And is it normal, because I bought it a year ago.
Here are my battery's properties:
Cycles ; 404
Health : 85%
Design Capacity: 6700 mAh
Current Capacity: 5703 mAh

i have to disagree with linc davis's reply.
system profiler, or what they call the system report will have your current battery health status. in power the system profiler will either display "excellent", "normal" or "check battery" the more charge cycles you have, (404 which you stated) the more the battery will loose some capacity. this is normal of lithium ion batteries
health 85 % is current capactiy (fully charged) divided by design capacity * 100 or
5703 / 6700 *100 = 85%
my mac book air, having it for a year states
cycle count 163
Condition : Normal
Charge remaining 4223
full charge capacity 4263
but system profiler, at least on my mac book air running osx 10.8.2 does not list design capacity. so i am wondering where you got that number. the mac book air i have is the mid 2011 11" model
if you feel after 400 cycles your battery diminished and you have apple care you can always ask them to replace the battery, but if you did not get apple care, then the year warranty would be up. a new mac book air battery outside of apple care or any warranties is $129 before tax at the apple store.
eventually the more cycles you have ( a cycle is being fully charged from being nearly discharged ) the more you are going to have to replace the battery. whenever you feel you are not getting the charge you used to get the discision to repalce that battery is your choice, but eventually you will have to replace it.
for example say the battery used to give you 3 hours amd now it only gives you 30 minutes, then yeah replace the battery. but if the time lost in capacity doesn't bother you that much, then don't replace the battery now
