MacBook Pro :: Battery Drains One Percent Per Minute
Jul 31, 2009
Ok so to start off, my Macbook Pro is around 3 years old. With my original battery having been through 350+ cycles, I had to buy a replacement. So I did some research and found that the Fastmac battery was my best bet for a long-lasting, reliable battery. I would say that Ive had the Fastmac battery for a bout 6-7 months without any problems whatsoever. However, recently Ive been noticing the drastic change in battery life. I installed Coconut Battery yesterday and discovered that my current battery capacity is 2266mAh with the original capacity being 5800mAh and 213 cycles. I also should note that the battery drains 1% a minute with no programs running (besides the Activity Monitor, which showed no strange behavior). Now luckily for me, My Fastmac battery is under a 1 year warranty, however I just wanna verify that it is a fault with my battery and not anything on my Macbook's side causing the battery to drain so quick. The last thing I want is to receive my replacement and then have to go through the same process 6 months later.
Also here is the Battery Information from the System Profiler.
Battery Information:
Battery Installed:Yes
First low level warning:No
Full Charge Capacity (mAh):2266
Remaining Capacity (mAh):1414
Amperage (mA):-1449
Voltage (mV):11421

I get the whole part about that I set my laptop to go to sleep in 5 minutes, and if I close the lid it'll go to sleep, and the little light at the bottom starts to pulse, etc. But in sleep mode, my battery seems to drain extremely fast!
For my old Gateway M275 laptop while in sleep mode, it would probably lose about 5-7% of it's battery in a day's duration. With my MacBook Air, I just came back to it tonight after a day's worth of sleeping, and my battery was down to 16% from 29%. And to check, it was indeed sleeping!

I calibrated my battery for the first time since Dec. When I plugged it in this morning, it took 3 hours to charge all the way, and now it's stuck on 99% full, 0:00 till completely charged, and I'm getting an error when I click on the battery in the menu bar that says "Service Battery". When I click on the error, it tells me that it may not be functioning properly and to take it to an authorized apple service retailer. Before I waste 2 hours by going to the Apple store and back, has anyone else had this problem, and is there a way to fix it without having it looked at?

My two month old MacBook Pro has suddenly developed what seems to be a battery problem. Can someone check this to make sure of it's legitimacy, the Energy Saver Settings are set for better battery life. I had been getting 4-5 hours with tons of apps open doing Word Processing/Internet on medium screen settings. This is on the lowest screen setting, Adium, Safari, Mail (and Coconut) running.

I've got a 17" Macbook Pro from May of 2007 that is serving me well now in my last year of college. The battery health began to deteriorate last year so I replaced it with a new one from Apple (a hefty $120).
Recently, the past two times that I have left for class (with my MBP fully charged) it has drained while shutdown (completely turned off NOT just "asleep"). When I say it drains, I mean it has roughly 2-5% of its battery life left giving me about 20 minutes of power until I get back home for the day.
Here's the kicker: the battery is in good condition with plenty of cycles left (see system profile for power below.)
Any thoughts? Try a new battery? Could it be the charger? What system components, if any, run during a complete shutdown and could these be malfunctioning?

I returned my 17 i7 MBP for a 15 i7, I have been torn between the 2. My question is the 15 battery seems to drain alot while sleeping. last night I was around maybe 40% and went to bed and now its 0%. coconut battery says 100% health. The 17 did not drain that much over night.
I will check it out tonight just to make sure I was right re the charge before bed.
I calibrated it last week.
Any thoughts? both 15 and 17 should get the same battery time?

I purchased a Macbook Air 2011 in December. It came with Lion preinstalled and it is up-to-date. Sometimes I experience excessive battery drains when the computer is asleep (lid closed), i.e. 40%-50% battery charge gone overnight.
This is not an expected behavior. The battery seems to perform well when the system is running, i.e. it last for 5-6 or more hours, so I think the problem is with the sleep mode. How can I diagnose sleep problems? Is this due to WiFi or running programs?

Mid-2013 MBA. Computer does not seem to sleep when the lid is closed. Battery drains completely. SMC update has been run. OSX 10.9.4. No peripherals attached, Bluetooth is off, network sharing is off. In Console I see at least three "Sleep failure" messages...they all begin with 0x00000000 but then have different codes. They are 0x21006c00, 0x1f006fc00, and 0x1f006500.

I've been playing Starcraft 2. I played first in Leopard but the performance was no good unless graphics were set to low. Even then, it was only just playable. So I switched to XP. Gameplay on medium graphics is great in XP. I've noticed that even though my Macbbok Pro is plugged in to the wall, it drains the battery. Last night I played so long that the computer shut down after the battery ran out of juice.
Specs: Macbook Pro 2.4, 256MB 9600GT, 2GB of ram (I have 4GB coming in the mail.) Leopard fully updated. Windows XP fully updated. I am plugged into the wall, not a surge protector.

I use first-gen unibody 15 inch Macbook Pro. I rarely shutdown and leave it sleep. However, sleeping somehow drains battery quite much. For example, after one day of sleep, my battery goes from 100% to about 60%. My previous Santa Rosa macbook pro never did this. My current setting is sleep and hibernate. I checked it in SmartSleep.

The battery on my MBP (2007 2.33 Core 2 Duo) has started to die, just like the three others that came before it. It seems like it's only been a year or so since I got a new battery. Yesterday, I was using it unplugged and the computer shut off when the battery was around 58%. I have never seen a battery shut off that early. The worst I had seen before that was a previous battery that would die around 35%.
A couple questions:
1. Is there something I am doing that is causing my batteries to keep dying so quickly? An Apple Genius told me that keeping the computer plugged in all the time can burn out the battery. I don't really want to bother putting the computer through unnecessary charge cycles to keep up the battery life.
2. Is there any way to recoup some of the lost battery life of my current battery, or is it just dead?
3. In replacing the battery, should I buy another Apple battery from the website, or are there better quality 3rd party MBP batteries?
4. On a side bar, I am thinking about purchasing a new MBP, but I am worried that the battery will have the same problem, and it will be much more of a hassle to fix because everything is internal now. I hate having to hand my computer over to Apple Care for a whole day and be without it.

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.
Coconut battery stats:
Battery capacity: 5141 mAh
Original battery capacity: 5770 mAh
Battery load cycles: 27
Age of your mac: 4 months

So I just opened Coconut battery, and it is saying that I have 101% battery capacity. How is that even possible? In the other hand, iStat says 100%.

I've had my Macbook Pro for just over 2 years and recently bought one of the 2010 models. I'm about to sell my old one but when I downloaded Coconut Battery, I saw that my battery holds a lot less charge than it did when it was new: Have I been doing something wrong or is it just low because the laptop is 2 years old? If it's something I've been doing, I don't want to make the same mistake with my new one.

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!

If I use my battery to 98% and I charge it, it shows it as fully charges. My cycle count is 4 and it is the 13'' mbp. It is 2 weeks old. I already calibrated it.

I bought a new battery for my sisters new used MacBook Pro. The instructions with the new battery was not to charge the new battery until it's was down to 2%. And, how many hours should she expect the battery to last until it needs to be charged? This is with normal web surfing with some streaming. The MacBook Pro is a 2.3 GHz Intel Core 2 Duo with a 15" screen form @ 2008.

I'm having a strange issue with my MBP 1, 1. It's recently picked up a new habit that I find to be rather annoying. When the battery gets down to between 5 and 10%, the laptop will just shut off. No hibernation, no sleep, just a hard shutoff. The battery seems to be in good health; although it does have a high cycle count, I still get around 2 hours of usage out of a charge. I would think that a calibration would solve the problem, but with the hard shutdown, would that even be possible?

So when I bought this the guy said that Apple installed a new battery on it recently. I believe him because when I downloaded the iStat Pro widget it said only 2 or 3 cycles which is because I calibrated the battery. But I just finished charging and the light is green. But it says the charge is only at 97%. I don't see why it should be like this. Also when it's not plugged in the battery only lasts maybe 3 and half hours from just surfing on the internet. But I thought it was supposed to last like 6?(I'm thinking that since mine is an older model, that could be it.

I noticed that my battery cycle (according to istat) switches over at 15%. So as son as it switches over to the next cycle I plug in the adapter to make the battery run a cycle from 100%-0.(I know the cycle in 100%) But it still switches over at 15%, that means that the battery ran only 85% of its capacity. How can that be? Is it possible to reset (delete) battery cycle data?
