MacBook Pro :: Incomplete Battery Cycle Of Charge?
Jun 12, 2012
I bought a MacBook Pro 3 months ago, despite in the first charge I follow the instructions of the store. The problem is that my battery doesn´t complete the cycle of charge, if I disconnect my computer and the value of the battery decrease at 95% 96% 97% 98% or 99% and I plug again the charger to the MacBook Pro, the battery doesn´t charge at 100%. I followed all the instructions of synchronization but the battery remains the same.
Info:
MacBook Pro (13-inch Late 2011), Mac OS X (10.7.4)

i have a 13" mbp with 130 cycles an i use it extensively.its been about 6 months since i bought it and i noticed tht apple will cover my battery in warranty fr one year only if it has less than 300 cycles on it.
my problem is tht i typically use my laptop fr no longer than 4 hours at a time. which means i recharge the battery jus before the battery meter hits red an counts 1 cycle as complete.thts why i got less number of cycles on the battery
cn i continue doing this without any adverse effects to my battery and its life ??

I just got my battery replaced and after a full charge both istat and mac osx shows that there is only one cycle available. I remember that my previous battery used to have at least 60 cycles. Is 1 cycle normal for new batteries or?

The title says it all. I have a new battery in my 2007 MacBook, but my computer still says it's at 237 cycles. Is there a way to reset the cycle count? It does say, however, the battery is at 100% health.

I have searched countless threads about battery health but I feel that each individuals battery health situation is so unique due to the numerous fluctuations.
I have a 2010 13" MBP with battery health of 92%. Load cycle: 13. and Age of 4 months( but i got it 2 months ago)
Should I be concerned with the battery health at this point?

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?

Well I've had my mbp(new model) for just a month now and the cycle count is up to 60 and battery health has gone down to 96%. Should I be worried or is it normal?

Just bought a new 15 inch retina MBP. My question is...should I immediately charge the battery or let it run to zero first and then charge it? Does it even matter?

So first off, I absolutely love my MBA. Now that we have that out of the way. Since day 1 I've noticed that the cycle count on the battery seems to be climbing MUCH faster than it should.
- I've had the machine 51 days. I was out of the country without it for 9 days so really, I've had it for 42 days.
- According to iStat and System Profiler my battery's cycle count is 37
- According to System Profiler my battery's health is "Good"
- According to iStat my battery's health is at 98% (It started around 96%, has been as low as 94% but seems to have settled in at 97 or 98% for some time now)
- According to system profiler my maximum charge is 5006 mAh. (It's also gone up a bit since the machine was new).
I thought the definition of a cycle was the equivalent of 100% depletion of the battery -- whether that's one long unplugged stint that sucks it dry or 10 really short ones. A cycle is the same as using ~5000 mAh of battery power. I've been really good about keeping it plugged in while I work (the outlet is conveniently located). I've run the battery most the way down maybe 5 times. I do, however, run it down 10 or 20% almost every day as the machine travels with me in sleep mode or spends the night unplugged in sleep mode at my girlfriend's place).
I haven't done any careful testing but it seems though that if I run the battery down just 20% or 30% or so and then charge it all the way back up the cycle count increases by 1. Considering I've only used it for 42 days, and the cycle count is already at 37, I'm worried that it will hit 200 cycles by the time it's 8 or 10 months old. Isn't the point where battery performance starts to wane? Anyone else out there notice a rapidly climbing cycle count?

I had some issues with battery drain while sleeping awhile ago but that problem has been solved. However, ever since that incident I could not be paranoid about the battery life etc.I heard people saying that leaving the charger plugged in is simply fine as long as I do the regular calibration once or twice a month or so. Yet, Apple stated that they do not recommend the laptops to be plugged in. I will be going to a college this Sept and I really do want my laptop to last at least the whole 4 years.
Ever since I have contacted Apple customer service about this Battery issue I have left my Macbook charged up and plugged in while using and letting it sleep. One thing I have noticed is that the battery indicator says 99% and doesn't increase or decrease yet the green light is on. Is that normal? Since this is my first Mac ever and also first Laptop I would like some advice on how to treat the Battery( I know how to do Calibration and such). Is it better to do full cycle usage of Alum Macbook battery than leaving it plugged in all the time? (I unplug it when the Macbook is off).

I have my Macbook late-2006 and suddenly the battery do not charge at cycle 103. I tried to talk to guys at Apple Store but the only thing they can do is to sell me a new battery. In fact, the battery was in recall before 2009 but I was not be able to send it back at that time. If the battery die only at cycle 103, is this normal?

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?

If you look at apple's battery life page it states the MBA battery is removable, I thought it wasn't supposed to be?Battery Lifespan For Apple notebooks with removable batteries ? such as the MacBook, MacBook Air, and 15-inch MacBook Pro ? a properly maintained battery is designed to retain up to 80% of its original capacity at 300 full charge and discharge cycles. You may choose to replace your battery when it no longer holds sufficient charge to meet your needs.

purchased a macbook Unibody back in October 2008 when they were released and use it heavily. The battery no longer holds a nice long charge - I get about 2 to 2.5 hours out of a full charge.
The battery has 149 cycles on it, which is obviously high (and correct, I use the hell out of it). With it still being in warranty, is it worth pursuing a replacement battery? Will Apple tell me to go take a hike with the high cycle counts?

been using my older MBP with windows 7 for a while and have never notice oddies with the battery until now. Then recently after replacing the failed HD and re-installing Snow Leopard on my 2007 MBP, the battery panel is telling me "Service Battery"; it's battery health according to coconutBattery is fair for it's age (50%).
the unit (battery) has been replaced previously due to being considered 'under performing'. Is Snow Leopard trying to encurate it's users to replace the battery more frequently? If not, does anyone know why this appears? I'm at lost, since it appears to work fine, if not charging completely.

So, I randomly clicked on my battery and noticed this "Service Battery" message. I had never seen it before. Obviously, this isn't a good thing. My Mac is 3 and a half years old so I'm not surprised this message poped up. So, I opened Coconut Battery and noticed my current battery capacity is at 65%. Even though charger says it's green, my battery isn't even charging. Should I make an appointment with Apple? My AppleCare expired so i'll have to buy a new battery when the time comes. I'm sure they're not cheap, either.

Is there such an application built in mac os x or a downloadable? I already have coconutbattery, but that does not give me the uptime numbers. I know there is one in istat, but it keeps going on if the computer goes to sleep.

I got rained on and my macbook got soaked. I dried out my macbook in an airtight container with some special salt for a few days, and luckily got rid of most of the water issues with my monitor. Unfortunately, my battery or logic board seems to have not been so lucky. My macbook is a one and a half year old 13" unibody, and now won't turn/stay powered on unless it's plugged in. For the first 15 minutes I've plugged in the magsafe charger, the battery is recognized. It says it's charging but stays at 0% (I then get the X over the battery icon). The weird thing is that my previously health battery now has a 0 mAh charge capacity and a 0 cycle count. Is there ANY possible solution to this, or has the damage already been done?

I have had my macbook for just 6 months....at the beginning it was perfect with a very good battery life.Now at 99% charge (as it refuses to finish charge to 100%) It now says 10:00 where the battery time is and last less than 30mins.
Also its charge capacity is JUST 708 !!!!It was over 4000 just 6 months ago.Im sure my battery is on its last legs, anybody know if I am entitled to a free one?

I have a Mac 10.6.8 running Snow Leopard. My battery won't charge: all I get is "Not Charging" in the menu bar battery status; the power adapter doesn't light up either. It's not a problem with the battery—when I put my battery in my friend's MacBook, it worked just fine. His battery, however, wouldn't charge either when it was in my computer. I have tried resetting the SMC several times, following the instructions exactly. I've reset the PRAM, run disk repair, and fixed disk permissions. I don't have the money to take it to a repairman—even if I did, I need my computer every day for work.

Our old battery said it was needing to be replaced and my dad went out and bought a new battery for our 15" MBP from 2008 - running SL. I've put it in, it works, I've plugged the power cord into it, and the little light that indicates it's charging doesn't turn on. I checked in the menu and it said the battery isn't charging.
I've already pulled it out and then put it back in, shutting down of course. And I just tried resetting the SMC which has done nothing. It's not under warranty. I've just put the old battery back in and it doesn't seem to be charging it either. I'd be curious if the power cord was faulty, but it's powering the MBP at the moment.

ijust calibrated my batttery and my charger light is green which signifies its not charging anymore..and the icon at the top of my screen says charged..BUT Coconut battery says my current battery charge is as follows:
Current Battery Charge: 5807 mAh
Maximum Battery Charge: 5853 mAh
@99%
Current Battery Capacity: 5853 mAh
Original Battery Capacity: 5770 mAh
@100%
Additional Info:
Battery-Loadcycles: 6
Age of Mac: 7weeks
Charger Connected: yes
Battery is charging: no
so my battery charge is stuck at 99% and its been plugged in for the past 3 hours, and its saying my current battery capacity is higher than my original battery capacity.. is that normal?.. i cant seem to get my battery to 100percent and its not charging..
here is a screenshot of coconutbattery after calibration, i just got my macbook last week..should i be worried about the battery at all?

1) When you first get your Macbook Pro, should you let the battery die out completely and then fully charge it? Or should I charge it fully first? Or what? I don't want to mess up the battery with the first charge.
2) Do you leave your Macbook plugged in while you sleep, are not using it, etc? Or is that bad for the battery?
3) I've heard somewhere that it's bad to shut your Macbook off when you go out/go to sleep. Would it be wiser to just set it to "sleep" and keep it plugged in or something?
