I upgraded to ML little bit after it came out and kept the OSX uptodate. I have 10.8.2 right now and battery still SUkS. I dont think my battery is bad because it says "Condition: Normal".

 

Is there any solution out there for this? or going back to Lion is the way to go?

 

I take my computer with me on the road every day, so I need the bettery life. One of the main reason I came to Macs. I am strating to think Apple SuKS at new things. They always have problem with all their new OSs and devices. Why cant they make it perfect and then launch.

 

 

But I dont care what apple does. I just want to fix this issue.

    Bad battery life is usually attributed to one of the following:

     

    1. Not fully discharging the battery

    2. Post-upgrade cruft (installing OSX Mountain Lion over Snow Leopard or Lion)

    3. Lack of sufficient hardware

    4. Psycological reasons (power of suggestion)

    5. Too many network requests (iCloud, Facebook/Twitter integration, automatic stuff), can be a number of failed network requests due to an update

     

    Course of action:

    1. Fully discharge battery and fully charge it again. Do this as often as possible, but at least monthly

    2. Just try to stop caring about the battery indicator, hide it and surf the internet and see if you can break the power of suggestion. Also, don't read too far into forums, they tend to be negative.

    2. If there is no change, try upgrading your RAM (to 16GB , its probably $50-$70 now, Crucial is a good company), as Virtual Memory can sap your battery (keeps the drive in constant use). Watch YouTube videos of RAM installation it before doing it, and remember to touch the metal of the optical drive to discharge static electricity before handling the RAM. Also, handle the RAM with care, touching it only by the edges. You CAN rest it on the black modules.

    3. Clean install/SSD upgrade. SSDs use less energy and are MUCH faster. If you are doing a clean install and you have $100-$200 lying around, buy an SSD. Clean installs are often a good idea because they are, well, clean.

     

    IMPORTANT: There have been many problems with the SandForce controller, so don't buy a SandForce powered drive. A good way to tell that a drive is SandForce powered is if it comes in 60GB, 120GB, 240GB, 480GB sizes. I would go for a Crucial m4 or an OCZ Vertex 4. I have used both drives and I would recommend them to anyone. The OCZ drives are a tad faster, but they are still a bit of an unknown, considering the flop that was the Vertex 2 and 3... The "sweet spot" for price vs performance is usually 256GB. Don't buy 512GB drives because they can be a RAID0 array of 256GB drives.

     

    A guide to optimize SSDs for mac is HERE. You should enable TRIM and disable hibernate.

     

    The best screwdriver is HERE. I know it's for oboes, but the different bits can fit any screw on the MacBook Pro (yes, even hex screws if you use the right bit, usually the biggest). Use the smallest bit for the screws on the back of the shell.

    You probably have some runaway process from incompatible 3rd party software.

     

    I wrote a little diagnostic program to help show what might be causing these problems. Download EtreCheck from http://www.etresoft.com/download/EtreCheck.zip, run it, and paste the results here.

    Your machine has been running for less than 3 hours. Maybe check again when you notice it losing a charge.

     

    Also, can you quantify what you are talking about? How long does your battery last?

    This is were I get confused;

     

    In the first response - "1. Not letting the battery fully discharge"

     

    A 2011 would be the type of battery that I thought a person would NOT want to discharge the battery fully to preserve battery health - or am I missing something?

     

    Thx.

    I assume Fhsjaagshs is talking about calibrating the battery, which Apple recommends from every month to every few months, depending on your usage.

     

    I suggest focusing more on point 2. "Just try to stop caring about the battery indicator". That's good advice.

     

    The problem is that you haven't really said anything. The only real information you've provided is Battery Condition: Normal. It is not possible to suggest any fix unless there is some symptom. What is it?

  • aikanae1 Level 1 Level 1 (0 points)

    I followed your link and it says (apx) computers made 2009 and later do not need calibration.

     

    Portables with built-in batteries

    Current Apple portable computer batteries are pre-calibrated and do not require the calibration procedure outlined in this article. These computers use batteries that should be replaced only by an Apple Authorized Service Provider.
