I have just bought a MacBook. I have downloaded the Battery Health Monitor and it says obviously that my current capacity is at 100%, with 5,791 mAh. I would like to know how many hours does this value correspond to, because it has certainly not been the highly announced 10 hours battery life
View 6 Repliesi have a late 2009 Macbook Unibody White, and just recently it started giving me these messages in the battery menu bar. I haven't noticed any notably difference in my machine, but im just worried about this message.I followed up with this message and started doing health checks, ect. And as you see from the images below it says my health is it 75% is that good? I really don't know and that's why I need your help!
(First picture showing what the problem says, Second picture is the message inside Apple's Menu-Bar Widget for the Battery, the Third Picture is the message inside a Menu-Bar App called 'Watts', Fourth is my Macbook's Battery information from the App 'Watts' and lastly the Fifth picture is more Information from the App 'coconutBattery').

Am i doing something wrong?? i just calibrated my battery -->
1- Fully drain battery w/usage
2- Fully charge battery - no usage
3- Keep charging when full for 2 hours
4- Use
Laptop was in box for 2 months, only been using for 2 other months
Am i doing something wrong?
i just ordered a late 2008 macbook pro 15 with the dual GPUs (9400m and 9600m GT) and I'm a little worried about the battery life.
-What can I expect if just doing normal every day stuff (web surfing mostly?)
-does watching a movie off of the hard disk use less battery than watching it off a DVD? Is there a big difference?
I'm not a big gamer but would like to have the horsepower to play a game should one come out that I want. I'm also not a big traveler so battery times are only of average importance.
Basically, I'm asking if I made a good purchase considering I have only average concerns for both battery and game performance. They had the new 7 hour battery 15" macbook pro for the same price but it doesn't have the dual GPUs.
I calibrated my MacBook Pro battery and then noticed that the battery life seemed slightly shorter after that. I calibrated it according to this: [URL]
Just wondering if I have done anything wrong...
One more question... What do they mean by "At this point, save your work. Continue to use your computer; when the battery gets very low, the computer will automatically go to sleep." Does it mean that I have to use the computer until it just shuts down or should I shut it down once the "Low Battery" warning pops up?

I have a 13" 2.4 GHZ white macbook that I bought in march of 2008. About 4 months ago I all of the sudden started having problems with battery life. It was very abrupt. I used to be able to take my macbook and sit through 3 classes or more with no trouble in regards to batter life. Then suddenly the battery would drain within a few hours. It has remained that way since.
I've spent the last month or so looking around forums and other places to try and find someone with a similar problem and possible solutions. As a result I've discovered that my situation seams to be somewhat unique.
Using cocoanut battery I tested my battery's capacity and it remains at a solid 98%. How can my battery still be at 98% capacity and have such a short battery life? I also seam to be losing charge while my macbook is closed. How and why does that happen? If I leave my macbook closed for a day or two it can lose up to 25% charge just sitting there!
I've tried loads of things including turning off unnecessary things such as sharing and bluetooth and calibrating my battery, all with no avail.
What is going on?? My battery is too old to be eligable for a recal and I'm not paying $30 just to have a phone conversation with a "Genius". If anyone has any idea what's going on and any possible advice, I would greatly appreciate it.
I am getting a very short battery life out of my "New" A1261 battery - we're talking 2.5 hours tops. I've recycled it a few times, but this is no where near the "7" hours that is quoted.

I've had this MBP for just over 8 months now, I'd intially purchased one in november, but the audio out used to give a crackle sound so they replaced the laptop. Moving on to the point - in the last week or so, I've noticed the MBP suddenly seems to get very hot and the fans turn on and thus suddenly becomes very noisy. I was using it on the bed so could appreciate that I may have been blocking the vents, but I've had it on a stand the past couple of days and it still seems to do it for no particular reason. The charger usually always gets ridiculously hot, but the MBP used to stay relatively cool, now the MBP gets hot independently of whether its being charged or not. Moreover, my battery life has gone from what used to last 4 hours, to around 2.25.
Cocunut battery gave the following stats:
Current Battery capacity: 4483mAh
Load Cycles: 222
Age: 8 months
My white unibody macbook battery that I just bought has a battery health of 92% and it only has 23 cycles. I got this information from iStat Pro

I reccently bought a new MBP late 2011. I took it out the box and charged it to 100% but the battery health was 94%(iStat) is it normal for a new battery to have 94% health? shouldn't it be 100%? I asked this question because when my brother bought his MBP early 2011, it had a 100% health out of the box.

I just bought the new MBP 13" 'cause I'm gonna need it for college, but since I'll also use it as "personal computer", for web browsing, playing music and movies, I'll probably have to charge every day. My question is: if I got home and my MBP is dead, I plug it in and use it, when the battery is fully charged, I have to unplug it or I can use it for the night (still plugged in) and just unplug it the next day for school?
Is it somehow harmful to my battery life? And by the way, I've read that "discharge the battery" means just use at least until the 50%, is that right? So if I charge it just when it's about 40%, I just need to recalibrate once a month, and that's all fine, right?
So I bought a macbook pro 13" about a month ago. I've been running coconut battery tests on it and the battery health is only at 89%. This is super upsetting to me. I went to the apple store and they ran their diagnostic test only to tell me that my battery is within specification, so they wouldn't replace it. The health they calculated was 91%.
What should I do? This seems unfair to me.

Hello people, I was just wondering if my Macbook Pro 13' (2010) battery is currently healthy? It has the health of 95% and 95 cycles. I purchased it 2 months ago

View 12 Replies View RelatedSo I've got a few questions about ways to prolong the life of may new macbook pro's battery...
1) How often should I fully charge/discharge?
2) At what % should I plug in?
3) At what % should I stop charging?
4) If my MBP is 100% charged is it bad to keep using it while plugged in? Or is it better for the life of the battery to unplug it and let it get used?
5) Any other tips/advice?
Only reason I'm asking is because my 2 month old 13" MBP is already down to 90% health after only 32 charge cycles .
I usually keep my mac connected to AC power and probably once a week I try to drain the battery. It only has 28 cycles. I bought it last year on november and today when I removed the ac power, a little while after I realized that the battery health went from 88% to 77%! What can I do? I am doing everything that mac says to keep a healthy battery!

I am confused as to what the "battery health" of my MBP is. I downloaded an app it told me it is 89% but it is not consistent with the cycles, mAh capacity, etc (it should be more?), so I am thinking the app might be innacure in reporting this (reviews say this). I just want to have a second source to see where I stand.

I was looking into buying a new macbook pro and I was just looking at my current macbook 13 inch and I hadn't checked my battery health for a while so I went and had a look. I was extremely suprised to see my battery had done 1046 cycles and according to istat, my battery was at 92% health...
I have had my macbook 13 inch since november 2007. It has been having a few problems lately with over heating but I was wondering if it was normal to have a battery that had gone through so many cycles and still have around 4-5 hours battery life (when I am just browsing the net and doing uni work i.e not watching movies or listening to music)
Just wondering why battery health would drop down to 96% from 98% using iStat Pro as my widget ?
I did a full drain of my MBA yesterday and ran it on reserve power and let it fully drain until it went to sleep, then waited about 6 hours after it went to sleep until there was no light flashing on my MBA....
I put it back on charge overnight and opened it up in the morning and it was fully charged, but the battery health now shows 96% as it was 98% a few days ago ?
How do I get the health back to over 98% ?
I am at 99% and 82 cycles and I've own mine for 2 months now. This is my very first mac so am I OK for now?
View 24 Replies View RelatedI've had my refurb rev a for a week now. I absolutely love the form factor and it has really impressed me with what it can do. (My last computer was the 1.67 Powerbook G4 with 1 gig of ram.) However the battery life concerns me. When I got the air it had 4 cycles and 97% health. 10 days later i have 15 cycles and 93% health. I'm not concerned about the cycles, but should the health be declining this fast? If not what can I do to increase it? I've tried calibrating it and it really didn't change anything.
View 3 Replies View RelatedI calibrated my macbook battery the other day and it went down to 97% (shock horror), its 73 cycles and 8 months old. In desperation I smashed it with a hammer hoping it would fix it. just joking I actually drained it down to 80% and then charged again, repeated this three times. After the first time the battery life when to 4058 mAh, then the second time it went to 4090 mAh and after the third time it rised again to 4126 mAh. Original capacity is 4100 mAh

View 6 Replies View RelatedI noticed this in my previous Rev. A. After 100 cycles, my health dropped from 98% -> 92-94%. Now on my Rev. C, I'm at 136 cycles and my health dropped from 99% -> 92%.
I calibrated my battery already, but is the MBA's battery just purposely dropping health after a certain cycle count or what?
Is my battery defective or is that normal. My battery is at 32 cycle count, 5 month old and 96% according to coconut
It's the new MBP "13
So I just got my first MBP, and I have calibrated my battery. Both iStat and Coconut Battery report my battery health is 98%. Do you think this is reason for concern, considering the MBP is supposed to be new? What is your new MBPs battery health?
