I've never full drained the battery below "50%" 61 times so I don't know why it says I've had 61 cycles. I always leave my laptop attached to the AC adapter. Is 61 Cycles with 99% battery life good for a 5 month old laptop?
View 13 RepliesI noticed that my MacBook doesn't run as long as it used to before I have to charge it again. I downloaded CoconutBattery, and it tells me that my battery is down to 91% of its original capacity after only 30 charge cycles. It's 5 months old according to CB, and I bought it new on Dec. 24th. (It's a Unibody White...) Is this normal, or should I take it into the Apple Store for a replacement?

View 6 Replies View RelatedI 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.
Im a little confused, is the Air Battery life that good? I've taken the following claims from the Apple website. MacBook Air - Get up to 5 hours of battery life on a single charge on the 11-inch model and up to 7 hours on the 13-inch model. 13" MacBook Pro - The new energy-efficient architecture in the 13-inch MacBook Pro gives you up to 10 hours of battery life on a single charge. I understand that Steve Jobs advised that they were using a better way to measure battery life for the Air that reflect real world usage better (WiFi Browsing I think?) so how does this compare to the MBP range? I guess the MBP battery claims were made using another older method, so any thoughts on how the Air's battery life compares to other PC's and Mac's?

Maybe it has to do with $

My Macbook's battery has done 902 cycles and is on 92% health.
I was just wondering - even though I know it's impossible to predict the life-span of a computer battery - a) how accurate that reading is (I use the iStat Pro widget) and b) ignoring the health reading, is it time to buy a new battery when it hits 1000 cycles?
The health has gone down from 100% to 92% in the space of about 3 months? Maybe more. Is that a sign that I should change it?
Ok, so I have a 2009 uMB 2.4 with 4GB/500GB and my battery cycle count with coconut Battery states it is at 418 Cycles and the Life states 96%, my question is?Is that good
How many cycles should I get out of the battery
This is the unibody MacBook the one they are calling the Classic uMB and I have had this since it was new, I bought this around February 2009, so just under 2 years old.
I know that the new 17 MBP can go through 1000 cycles or so of battery use. But what can the 13" MBA go through?

View 8 Replies View RelatedHere's the battery info:
Cycles 47
Current Max 1269 mAh
Age 3.1 years
My older battery (this is my second one) is in much better shape than this one.
Info:
MacBook Pro, Mac OS X (10.7.4)
The MacBook Pro is a 13' unit. it was replaced with a SSD drive. The battery has 327 charging cycles on it. Sometimes when using battery only the machine will start to boot up, will get the logo then immediately shut down, screen goes black then the process continues, once I connect the AC power the Macbook boots correctly. Should also mention that the circuit board that controls the charging of the battery was also replaced (outside of warranty period) several months ago as well.

My AppleCare expires on Monday September 6th, and I am wondering if my 87% capacity at 51 battery cycles suggests I should visit an Apple Store this weekend? The closest store is around 25 miles away, so if I would be wasting my time, I would rather not take the trip. My concern is mostly based on my warranty ending. This is a 2009 13" MBP.

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 15 Replies View RelatedJust wondering, but how rare is it to have a battery that lasts 3 times longer than the "rated cycle amount"? Apparently this battery should have been dead 600 cycles ago... I am finally now noticing a slight loss in overall battery life.
I have used this MacBook 100% of the time since the day I have gotten it over two years ago. Is this why it has lived so long?
My macbook battery broke 500 cycles, and the battery life was at about half what it used to be so I ordered what was described as a brand new battery from Westronics, through Amazon. I put the new battery in the machine and checked System Profiler, and it is telling me that the battery has 15 cycles on it already. iStat Nano says the same thing. Is this normal for a new battery to have cycles on it already? Or did I not get a new battery? I just want to make sure I got what I paid for.

View 10 Replies View RelatedI get ready for the next disappointment tomorrow (maybe no MBP update) and looking out for a MBP at eBay. I've found a good one (August 2009) 2.53 GHz, 4 GB RAM, 500GB HDD etc. for round about 900� (1.200$) (in Germany we pay 1533� for this model so round about 2088$). The guy sent me a screenshot of the battery capacity which is 87% (4762mAh) after 56 loadcycles. Is that acceptable? IMO it's a bit too low - what do you think? Maybe I'm going to buy a AppleCare Protection Plan afterwards ... would the battery be covered?

I know it's expensive- but how is the result in real life? Looking to get a Mac Air black with blue hinges. But I have read that it looks like a after market paint job versus a true original color look.
View 4 Replies View Relatedi 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 received a Black 2.4GHz MacBook that I bought on eBay a few days ago to add to my collection. The battery reports 828 charge cycles, and has about 82% of it's original charge capacity, and still lasts a good 2.5 hours. What I want to know is, is it unsafe to use it like this? Apple Battery FAQ doesn't not really say when to replace the battery, besides when it doesn't hold that good of a charge anymore.
Should I be worried?

I calibrated my battery already, but is the MBA's battery just purposely dropping health after a certain cycle count or what?
