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.

  • Connect a macbook pro to on old tv with only aerial cable input

    I'm trying to connect a macbook pro to on old tv with only aerial cable input, i have a mini displayport to vga, vga to s-video/phono(yellow) and a phono to aerial, the macbook doesnt recognize it as a display, any suggestions? Can i force it to send the signal?

    its not for picture quality the screen is not much bigger, its for an arcade emulation in an exhibit, so i wanted a crt type moniter, and low qulaity output, what input would an old style tv need for it to work?

  • AppleTV audio out to old amp with only analog audio

    I'm thinking about getting the Apple TV for both video and for playing my music on my home stereo system. I currently have an old amp with only analog audio capabilities, but the new ATV looks like it only supports digital optical out, and the digital to analog converters I've looked for seem pretty expensive. How can I get the audio from my music collection (iTunes) to play wirelessly through ATV through my amp?
    I currently also have an Airport Express which I use for audio, but I was thinking of selling that and just using the ATV since the ATV can essentially do the same thing as the AX with added video benefit. I've seen some threads on streaming audio from the ATV to the AX, but do I really need both? Seems like there should be another way.
    I was thinking of connecting the ATV to my TV via HDMI cable for audio, and then using an analog audio out from the TV to my amp. But, if I'm correct, that would only provide me with sound coming from the TV. It wouldn't give sound out from iTunes, for example. Is that right?
    Are there any other options?

    Followings are my observations in audio streaming with Apple TV 3 and Airport Express through AirPlay protocol:
    -- Apple TV 3 come with only digital audio outputs through HDMI and optical SPDIF outputs. If you connect optical link from the optical output to optical input of any DAC and HDMI cable from the HDMI output to HDMI input on TV set, audio output will be transmitted through both digital outputs. Thus is is not necessary to turn on TV set unless visual feedback is required. There is no audio analog line output for Apple TV 3.
    -- AirportExpress come with single combo mini jack (digital + analog) for audio output regardless of old/new models. You can connect either digital optical link (with Mini/Toslink adaptor) to digital input of DAC or analog line cable (inferior) to analog line input of amplifier. When analog line is used, digital-to-analog conversion is done by DAC built into AirportExpress for which do not expect quality is as good as most external DAC models. What do you expect from a single-chip DAC implementation vs standalone DAC models cost few thousand dollars ? Moreover analog line is susceptible to interference more than digital line.
    So the decision to use Apple TV or AirportExpress, analog or digital transmission for audio streaming depends on whether you need WiFi base station features of AirportExpress to establish wireless network and quality of your audio system to justify all-digital audio transmission. Followings are what I use in audio streaming from iMac/iPad mini /iPhone 5 to audio system in living room. Quality of audio output is comparable with Sonos Zone Player as audio source.

  • 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.

  • 20 month old MBP with only 80% battery capacity

    Been noticing my 09 alu uni body 13" MBP now has a battery capacity of just 80%, according to Coconut Battery. I realise this app might not be too accurate, but I only checked it as I've been noticing a reduction in battery life recently.
    I've been using MB's for years and employ all the usual good practices, I also regularly recalibrate the battery, although I understand these new non-replaceable models don't require it, nonetheless, it can do no harm.
    My question is, is such a reduction in the batteries capacity normal on this machine after just 20 months use?
    BTW- The use consists of running on mains at work during working hours, resting over night during the week, use on battery/mains at home at the weekend. According to Coconut the battery has had 348 cycles. Again, no idea how accurate this app is!
    I have 3 years cover on the machine, so it it's deemed this is not usual I can pay the Apple store a visit, but I'd be interested in the views of other users whether this is normal or not.
    Thanks.

    If you think that's necessary. But losing 20% capacity in almost 2 years is pretty good for any battery. It's just that we can monitor it more accurately now.
    You can get your current capacity vs design capacity via Terminal without coconut:
    ioreg -l | grep Capacity

  • 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!

  • My battery Bar is drop when full charge

    I m using BB 9800 when I charge my phone full charge it does drop the bar when I start using it and it can last up to 8 hour and d battery will remains like that once the battery is low it drop to red bar. Can anybody help with how to fix this problem please

    Hi and Welcome to the Community!
    Please try this sequence...note that, throughout the entire 4h15m process, your BB must remain directly connected to a known-good wall charger (not PC USB, not a cradle):
    With the battery inside, connect your BB to the wall charger
    Leave it alone for 2 hours, no matter what the LED or the display does
    Remove the battery
    Wait 15 minutes
    Insert the battery
    Wait another 2 hours, no matter what the LED or the display does
    This has been known to "kick start" some BBs.
    It is also possible that your battery or BB has experienced a problem...to test, this sequence is needed:
    Obtain an known good and already fully charged additional battery...use it in your BB and see what happens
    Obtain access to a known good and identical BB...use your battery in it and see what happens
    The results of this will indicate if it's your BB or your battery that has the problem. Note carefully please that "new" and "know good" are not necessarily the same things. While rare, a "new" battery certainly could be defective. Rather, the simplest (and least costly, btw) method to conduct this test is to find someone with an identical BB who has no issues...trade batteries and see what happens.
    Good luck and let us know!

  • 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.

  • How do I get iTunes to work on an old laptop with only 300mb of ram

    I have an old Compaq pressario with just over 300mb of ram that i want to run iTunes on. It has a slow processor which does not meet the recommendations but I just wanted the bare functionality to run and setup an iPhone for my mother to use. It is an old celeron 800 MHZ processor.

    You forgot to mention it.
    You need the linux-headers package for this.
    Edit: the linux-headers for your running kernel that is, not the one currently in [core]

  • Backing up 2 year old iBook with only 1.98GB of memory left

    I recently bought a external HDD(120GB Maxtor OneTouch mini) to back up my 60GB iBook. I am wondering is there any difference between backing-up files using the accompanying software (onetouch manager) and just copying files to the HDD by clicking and dragging? The internal HDD is nearly full and I would like to erase unneeded photos etc. after transferring them to the external HDD but I want to be sure they are secure.
    Any advice/ideas would be appreciated, thanks.

    Welcome to Apple Discussions!
    Just one suggestion about the photos--also burn some CD's of them at some point as additional backup. It's best not to entrust anything you care about to a hard drive alone, just in case it might fail some time in the future. And it will give you extra security that your photos have been saved in two different ways..
    Good luck!

  • My iPhone 5 iOS 7.0.4 still gets hot and drains battery with everything but cellular turned off.  What to do?

    Have a new iPhone bought in late July 2013.  It had zero heating issues and battery issues until the past week (Nov. 2013).  Now, the iPhone gets hot to the touch and the battery drains within 2 to 3 hours, EVEN AFTER I HAVE DISABLED ALMOST EVERY FEATURE OF THE iPHONE.
    This iPhone has iOS 7.0.4, installed within last 36 hours.  I then erased the entire iPhone and restarted it as a New iPhone.  Then I went in and turned off everything in the way of Settings that permit disabling.  All notifications, spotlight searches, application updating, accessibility features, push features, location services, etc. were turned off or disabled.  Brightness is set to Auto.  Don't use the iCloud. 
    After doing all of that, which essentially rendered this iPhone just a clunky old cell phone, not even using WiFi, I connected to iTunes on my computer and restored my backed up apps, photos. 
    After the Restore, I went back into settings and made certain that, again, all notifications, app services, location services, updatings, etc. were disabled, still.
    The problem persists.
    It seems the only solution is to get rid of all my Apps and never use WiFi, or iCloud, or Mail.  That is unacceptable.
    Does anyone have a solution, besides my calling on the warranty on this phone?

    Basic troubleshooting from the User's Guide is reset, restart, restore (first from backup then as new).  Try each of these in order until the issue is resolved. 
    If the problem continues, take the device to Apple for evaluation and possible replacement.

  • IPhone 4s power failing within 3 hours with only 2 calls after charging overnight

    My wifes iPhone power is failing within 3 hours of overnight charge, after only 2 calls and reading about 4 e-mails. My phone however works fine. Both are the same model 4s. Any ideas?

    I have been getting 2 - 4 days use on my 4s after each of the 7.x upgrades.
    I haven't had 7.0.3 for that long, but my phone now shows 14hr 55 min standby with 2 hrs usage and 76 percent battery left.

  • How do we deduce (if we can) SMTP address for an exchange account with only x500 address available? In what cases SMTP address is not available for exchange accounts (please see details below)?

    I am using PR_SENDER_EMAIL_ADDRESS to retrieve sender's email address for exchange mails, but for some mails I only get the exchange X500 addresses. In such case, I can use PR_SENDER_ADDRTYPE
    to check the type but when I detect an X500 address instead of an SMTP one, is there a way I can enhance SMTP lookup? What might be the reasons that SMTP address is available for some External senders and not for others, as in my case? I am using MAPI CDO
    1.2.1 with Exchange Server 2010.
    MSDN Question

    If you getting an X500 Address that generally means there is Directory object (in Active Directory) for that sender, if its an external sender then it most probably there is an AD Contact from that Sender. The best thing to do is just use resolve method
    in CDO to resolve the X500 Address to the Directory object and you should then be able to get the associated SMTP Address from the recipient object. (you also just use LDAP to lookup Active Directory directly).
