Battery under 80% with only 157 cycles

Hi everyone, I wanted to see if anyone could help me and confirm my worries before going to a Genius bar.
The thing is that I've been always concerned with my battery life in a Macbook pro 13" bought las November 2009. And now I've seen that the battery health is already 78% when I only have 157 cycles, far far way too low from the 1000 cycles Apple claims for its in-built batteries in the MBP.
So I wanted to see if anyone could tell me what's going on, or confirm me that I should go to a Genius bar and they would replace it or how can I get it fixed.
Thanks everyone! here's the battery information:

Battery health 96% with only 18 cycles

A month ago I bought a brand new unit of the last version of the old 17" model. iStat Pro recognized the battery as new with 100% health. 30 days later it shows 18 cycles and 96% health. To what extent this information is trustworthy? Can I ask for a replacement if that fast aging process continues?

Don't worry about it too much. My battery's capacity level swings several percentage points even if I check it at different times during the same day. You will probably find that the deterioration rate will not continue linearly, but will stop and even reverse at times.
Battery readings fluctuate normally because a battery is made up of many cells that all behave slightly differently and deteriorate at different rates. It's hard to accurately track/predict the performance of all of the cells as a group; the number is always more like an estimate.
Apple has a standard that its batteries should retain 80% capacity after 300 cycles. Apple might not replace the battery until you can show that the battery is going to fall short of it at that time, and it takes about a year to get to 300 cycles.

Battery service warning at only 40 cycles

Hi all,
I'm running a MBP early 2011 15 incher, and just recently upgraded to Mavericks. Lately by total battery percentage capacity has been fluctuating quite a bit, jumping between high 80s and low 90s, which I figure was pretty normal behavior. Had been dropping to mid 80s recently. After about a week of non-use, turned it on to see a service battery warning by my indicator, and a total battery percentage of only 76%! Rather alarming especially the light usage. I leave it plugged in a lot of the time, and drain it every now and then to about 20% and bring it back up. With only about 40 cycles over the last couple 2.5 years, I'm pretty shocked, especially with claims of 1000 cycles and only using about 20% total batt capacity.
I've reset the SMC in the past but battery capacity by coconut still shows some fluctuation. Do I have a bad battery?
Thanks

Theres a chip on the mac called the system management controller which controls battery management etc resetting it might help you

18 mo old battery with only 83 cycles full charge = 64% ... what!

The battery in my 18 month old late 2008 model MacBook (unibody) has had only 83 battery load cycles yet will only charge to 64% (2651 mAh vs 4100) at full charge.
Needless to say, this is disappointing when the local Apple dealer tells me it should be fine to 300 cycles. As an Apple user since the late 1970s Ive been able to fix most of my problems on my own ... but doing all the usual battery fixes does nothing. The battery is crap.
Very disappointed in Apple battery quality. No way I can pay $140 to replace what should be still fine. Ugh. And $49 for a tech support phone call, Apple. Come on.

Relax. Technology's not perfect. You have regularly calibrated it, haven't you? Maybe you should have bought AppleCare...
Oh, and Apple doesn't make the batteries.

5 days old Mbp 13, istat show that the health is reduced to 96% WITH ONLY 4 CYCLES!

Hi to everyone, here's my trouble!
As it shows full charge, and health to 96% in 5 days after I purchased this one to replace my 2008 mbp15. Also the battery drains a lot faster than I expected, and I'm only doing web surfing at this time, don't have time to install protools yet.
I know, you might say, "dude, 96% is a good battery " My answer to that would be "4 cycles!!!!" I also read that other mbp 2011 are having drain problems, don't know if they use istat, but I used it on my previous mbp and always showed correct info.
Any comment on similar situation, please let me know. I will keep searching for info
Thanks for the space! Cheers!

Would you stop stressing?
Go have a read through the forums at all the posts about batteries, and you will find the majority are the same question you are after 4 cycles.
It's going to last you 2+ years if you treat it right / 300+ cycles.
I've seen people post saying their battery is stuffed after 800+ cycles!
And they are $100 to replace... Seriously, is it really worth stressing over 4%?
Just enjoy your new mac & have fun!

The battery for my Macbook Pro 13 "has only 121 cycles and is not charging anymore, my Mac is telling me that it is necessary to exchange it. You have any tips for me to find out what might be happening with my battery?

Guys, i am actually trying using a solution provided by the article shared by dominic23,
It says "Another option is to get an ionizer to help the atmosphere in the workplace be more conductive and pull charges away from contact surfaces, including yourself."
So in my home, we have such device that could clean the air using ion, and i am using it in my room...
Result: BANG!!! The electric shock on my macbook has gone!! I don't really care about physics but somehow it works! You guys should give it a try.
Thanks again dominic23

144 cycles with only 6% health, is that normal?

Hi there!
I´m writing you from Spain cause it seems than the Spanish Apple support service is unable to do or to tell me anything else about my battery. As I wrote on the subject my battery is just with a 6% of health after only 144cycles. The weird thing is that in spite of the fact that the battery is doing more cycles now, the cycle counter doesn´t change at all! Is that normal?
Do you think I can get another new battery without any charge? My MBP is from March 2007 but it seems not to be under the exchange battery program.
Thanks a lot!

Have you calibrated your battery?
http://docs.info.apple.com/article.html?path=Mac/10.4/en/mh2339.html
After doing this, do a PRAM reset:
Shut down the computer.
Locate the following keys on the keyboard: Command, Option, P, and R.
Turn on the computer.
Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.
Then, lastly, an SMC reset:
If the computer is on, turn it off.
Disconnect the AC Adapter and remove the computer's battery.
Press and hold the power button for 5 seconds and then release the button.
Reconnect the battery and AC Adapter.
Press the power button to restart the computer
This should hopefully reset the callibration, and your battery should get better. It's possibly not the battery that's at fault, but how the mac reads the information on the battery

My battery was at 11 hours per cycle. Now i only have 4 hours since i downloaded os x maverick am i the only one who has this problem or could it be a malware

My battery was at 11 hours per cycle. Now i only have 4 hours since i downloaded os x maverick is this just my computer or could it be a malware.

Actually coconut battery works perfectly fine for Mavericks, many pro-users on this board are using same with Mavericks, so, incorrect.
I have done exhaustive testing on same on several diff. Macs with Mavericks
SMC reset will show correct battery reading for a short while, however no, "time remaining" is NOT correct currently, and techs. are working on this occurrence. Your experience with Mac has no bearing whatsoever on current time remaining indicator with Mavericks.
Endless testing shows that accurate time remaining will present itself, for a short time, after a SMC reset, but this is often very short lived.
The quickest methodology to FAULT this reading is to open a high task APP (photoshop, video feed, flash, etc.)
See post on page 10 of this thread.
*Further testing on 3 machines 2 days ago have shows that if a wake from sleep is induced, the "time remaining" on a 50-60% charge will show "20 hours remaining" on 2 diff. macbook Air 2013 13" I5 (very inaccurate of course)
Battery APPS used were:
1. Mavericks resident batt. indicator.
2. coconut battery (coconut doesnt estimate time however but mAh)
3. Battery time v 2 (mAh and % remaining, not time remaining)
4. Battery APP "fruit juice"
*For those receiving ACTUAL LESS battery life, other variables are in play
Happily however, my ACTUAL TIME on a full charge on 2 diff. Air (mine and a borrow) has increased an average of 25%

Battery Issue. I only have an hour worth of battery life at 86% with minimal background lighting and only one web page open.

I currently have a macbook pro with about 130 charge cycles that was purchased in August 2012. After about an hour unplugged with no activity only an hour and 54 minutes remain w/ 86% battery. According to coconut battery the battery health is at 85%. Should I bring the macbook into the apple store? Earlier today I lost 20% of my battery life in 20 minutes with only word open. I recalibrated the battery as well and I havent had any improvement.

purchased in August 2012.
I recalibrated the battery
Your model Macbook does not need calibrating according to article - Calibrating a portable computer battery
Current Apple portable computer batteries are pre-calibrated and do not require the calibration procedure. These computers use batteries that should be replaced only by an Apple Authorized Service Provider.

MBP Battery Troubleshooting:
To check for a bad battery, go to Apple/About This Mac/More Info
In the System Profiler window, select the Power entry & look for Health Information.
If next to Condition it says "Check Battery" then your battery is probably on the fritz.

I'm afraid you'll have to get the phone serviced, dropping the phone must have damaged additional parts inside the phone.
But Apple will not service the phone anymore, opening the phone and replacing the battery should only be done by authorized personal, not by users.
You'll have to look for a 3rd party repair shop and see if they can fix this, sorry.

With brand new iphone 4s when plugging into computer itunes shows a blank page with an apple logo in top left and a small lock in the top right. right clicking iphone under devices shows only eject.

T400 does not start up with a battery and AC, but starts up with only AC.

I bought T400, 7417-CTO in Jan 2010. My T400 does not start up with a battery and AC power. I tried to start with only AC power after pulling out the battery, it worked fine. Even when I inserted the battery in T400, which was running perfectly with AC only, T400 seems to lose the power - more strictly speaking, it kept stoping and re-running several times, and finally it dead.
a few possibilities
1) a battery is dead - but it does not explain the failure with both AC and battery
2) some hibernation issue - I plugged in and out the DIMM, and clock battery. I tried to keep pushing the power button trick, but it didn't work
3) Mother board failure??
I really appreciate if you give me some advice on it.
Wanyong

Thanks for all your kind and helpful comments.
Unfortunately, I don't have any friends who have Lenovo - or I don't have many friends here since I moved in the last summer. ;-)
After purchasing a new battery, I will update it. Hope that this thread helps someone who had/will have same prob. as mine.
