    This is going to sound really weird, but after the latest java update my battery life greatly increased...I have no idea why.

     

    That is interesting.  The latest update actually removes the Java applet plug-ins from all installed browsers.  It looks like Apple is no longer going to support Java...understandable since Java presents a number of security vulnerabilities which have been exploited previously.  If you run into a website that requires it you have go to the developer, Oracle, to download it.  So the onus is on them to keep it current.

     

    The update also removed the "Java Preferences" app from OS X Utilities.

     

    So if there were some sort of Java Runtime app executing on your MacBook, getting rid of it could certainly improve battery life.

     

    Due to the security issues I've always disabled Java (not to be confused with JavaScript) but some folks need it for VPN and other activity.

    I didn't receive the latest update through App Store and i don't have Java installed, When i click on Java Preferences it's showing me “To open Java Preferences you need a Java SE 6 runtime. Would you like to install one now?” I clicked not now.

     

    I still have the Java Preference installed in Utilities folder as you mentioned that latest version will remove the Java Preferences and i didn't receive updates from Apple yet :/

    I wouldn't worry too much about it.  Sometimes I've seen updates being release (OS X, iTunes, etc.) and I get a notice via the Mac App Store the same day and other times days, maybe a week later.

     

    However based on the earlier post by shadow82x, it did seem to help with battery life, at least for him.  So if you want to install it you can download it here...

     

    http://support.apple.com/kb/DL1572

     

    After that if you really want Java you'll have to update it from Apple as well as download it directly from Oracle:

    Of course there's no need to have it if you don't need it...and if you need it you'll know it.  More here...

    I still haven't figured out why the update removed Java Preferences from my iMac, but not my MacBook Air (both on ML).

    Hi Again,

     

    Thank you for your respond. I could see that i'm still seeing Missing plugin in my safari browser when i visit http://javatester.org/version.html it's showing missing plugin i think i mightn't get the java update via Mac App Store and on iMac i'm getting “inactive plugin” when i visit that website as well if i click that button it redirects me to enable the java.

     

    However, I already got Java update on my iMac which is currently running 10.7.5 and it doesn't run Mountain Lion, iMac has Java installed because i used to play Minecraft game it requires me to have Java. I'm a bit confused that i didn't get any update that's relating to Java on MacBook Pro (It's clean installed version of Mountain Lion doesn't have Java installed).

     

    Also when i click VisualVM in spotlight like the one shadow82x mentioned it's showing “To open “Java VisualVM,” you need a Java SE 6 runtime. Would you like to install one now?”.

     

    Thank you for sharing the information with links.

     

    EDIT: I did update on iMac the Java Preference has been removed from the system when it's updated. Also it's showing missing plugin on iMac when i visited JavaTester.org.

    I have a late 2009 17" Macbook Pro.  Took it into Apple store, they said the battery is fine, has 100 charges on it, had less than 3 hours when in the mid 90% range.  In selecting the energy saving graphics option in preferences, it only added 10 minutes to the battery life.  As I remember my pro was to have at least 5 hour life, so now is around half the new value.  I guess we have to wait for 10.8.3.

  • toolnard Calculating status...

    Thank you to everyone who has helped me. My battery is currently at 64% and is listed to have 4:11 of battery life. That is just in line with what you all suggested.

     

    I really appreciate all the help and I am glad everything is working properly.

     

    Once again, thank you.

  • slego Calculating status...

    Personally, I'm done with Mountain Lion.

     

    3 months of searching for solution/fixes, waiting 10.8.1, 10.8.2 brought just nothing.

     

    2 hours for MBP Mid 2010 as a maximum with super heating of the left side.

     

    So, clear install of Lion (10.7.5) has fixed this for me. Now it is 3.5-4 hours.

     

    Taking into account ML has nothing special (does anybody really feel any benefit of that 200 features?), comparing with difference between SL and Lion - that's not a big loss.

    I think you're right.  Mountain Lion seems to be a bloated system that's more a hassle than a benefit.

     

    All the best.

  • devilsgenius Calculating status...

    It has been 4 months since I upgraded to ML on my early '11 MBP and my battery jumped to "Service Battery". I immediately did all that has been mentioned here e.g. clean instal to SL, Lion, multiple resets etc etc. Nothing helped. The battery's health kept jumping up and down at around 5-6% every week until subsequently reaching 11% last week lasting for not more than 45 minutes on a full charge.

     

    For more than 2 months, I kept calling AppleCare India. All through, they were courteous and polite. Each call lasted atleast 30 mins with senior advisors, explaing to them about the case, issues as reported here and being explained about all the data logging activites sent by Apple. I also had it checked at an Apple Solution Expert (sadly, no Genius Bar in India), and they had confirmed that it's the battery fault and has nothing to do with ML. The engineer reports stated that the fact that battery got faulty just after the upgrade was an "unfortunate coincidence", and that the only way out was a paid battery replacement.

     

    After the first two months, I lost hope and decided that I'll let the battery die completely and then think of what to do, waiting for any updates from Apple in the meantime. On contacting AppleCare India a month back, a senior advisor was courteous enough to call up all the Apple Service Providers in my city getting the best possible quotations for the battery replacement, and refer me to them.

     

    He matched me a battery replacement offer at one of the Apple Service Providers for aprox. US$107. I took my machine there on Thursday, placed an order and by Saturday afternoon received the call from the ASP saying that the battery is ready. I took my machine to the ASP and it took them about 45 minutes to replace the battery. The service though was good.

     

    Last night, I just upgraded to ML from Lion and did a combo update to 10.8.2. So far though a little early to say, things are going good, I think. Keeping my fingers crossed, I get about 7+ hours of normal usage. If at all anything is still wrong with ML, I hope I spot the issue within my 90 days battery warranty period.

    My 4th MBA appears to have no problem whatsoever. Left in the corner is the estimated battery life, 8:14 hrs. let's be realistic, it will be more like 5-7 tops. Of course tiping this it goes up as not consuming anything. 734 near is is the temporary wattage, in miliamps hour.

     

    As richadams said, I did not reinstall flash. It is painful. Not only is Flash not dead- and Apple sellers have been arguing that for years- but is dominates just about any site I need something from. Youtube, Sports, news, streaming.. so on.

     

    SO three MBAs defective in a row. If people still have a hard time imagining this, they should just check my posts, and see the varying serial numbers. With the 8 Gb config, it means none of them could have originated or been swapped in a store. And for each one to be returned, Apple had to admit a defect.

     

    Some MBAs and MBPs just have issues. Think of the latest dinged iPhone 5s, iMaps, so on.

     

    Should you get 2 hrs instead of 4, drop one OS. As for this one, I cannot install Lion nor am sure Lion would give me more than 6 hours. I would install it if I could.

    Hi Chris,

     

    This looks like you have replaced the battery or it's new MacBook Air as i can see the cycle count that starts from 0/1 cycles so you may have longer battery life.

     

    As for me i have 395 cycles count (it's only 1 year and 2 months old) and the battery life is still the same even tried to the clean install like richadams said nothing has gotten improved just 20 minutes is difference.

     

    Would you recommend me to replace the battery?

     

    Let me know

     

    Thanks

    Sulaiman.

    Hi Sulaiman, just want to ask because my MBP9 13" mid 2012 is 19weeks old and the battery cycle is about 125 and the battery health is 92% and i use it like everyday and i dont put it on sleep i just turn off the display at night and the keyborad light and most of the time i just leave my cable charger plugged... is this normal? because now I'm planning to go to apple service center near my place to ask for replacement of battery if its possible because it really drains so fast and now it only gives me like 2-3hrs when it is full charged =(

    I'm doing exactly like you and i use my laptop daily. Yes it's normal if you keep your laptop plugged in long as possible nothing will affect. I don't know if you replace the battery it will help or not but i heard few users in this thread that they solved their issue by replacing the battery as for some they did clean install and smc resets it does help and this case hasn't still resolve for other users yet including me.

     

    Your battery health at 92% is normal if it's goes beyond 80% it's negative battery heath. If you would like to give a try by replacing the battery you can do that - it can also improve your battery life but i can't confirm this case if you're in warranty or even with AppleCare you're lucky enough to replace the battery within warranty.

     

    I'll have to wait and see if there new update that could fix the battery life issue.

     

    Thanks,

    Sulaiman
