Does Mavericks have any effect on MBP battery life?

Does updating to Mavericks have any effect on the battery life of the MacBook Pro?

It's suppose to have a postive affect on battery life. At least that's what I'm seeing in comparison to OS X Mountain Lion (Macbook Pro Retina).
See Conclusion at the bottom of this PDF from Apple. You can also skim through the PDF to see how battery life is extended.

  • Resizing a TIFF File: Overwriting TIFFFields does not have any effect

    Hi,
    I have some TIFF files that I am receiving through a FAX server. Some of the TIFF files have an image length of *1077 pixels and a DPI of 200x98*. These images open fine in generic viewers like Microsoft Image Viewer and IrfanView and the image size in the information dialog shows up fine (1752x2158). But when I open the images in a LeadTools viewer (that works off TIFF Header tags), the image appears stretched out.
    I am trying to re-sample the image to make it a true Letter size image (1700x2200) with resolution of 200x200. I have been able to set the TAG_X_RESOLUTION and TAG_Y_RESOLUTION which I can see changed in the Tag Viewer. But changing the following tags does not have any effect on the resulting image:
    TAG_IMAGE_WIDTH
    TAG_IMAGE_LENGTH
    TAG_ROWS_PER_STRIP
    the following is the code I am using, I have tried all possible ways (removing TIFFFeilds and then adding them), but it has no effect. The last options is to use a Print Driver from within Java and Print the image (that re-samples it into a 8.5x11 inch image with 200 DPI). At this point, I am just curious about writing TIFFFields with images. Any ideas are appreciated:
    Thanks,
    Manuj

    The resulting image with this carries the updated DPI values (200x200) but still carries the old values of 1752x1077, the length being exactly half of what Irfan view is showing.

    Your problem for some reason sounds familiar.
    EDIT
    Ok, now I remember. Your post is like this one in the old forums,
    http://forums.sun.com/thread.jspa?forumID=540&threadID=5425983
    Basically, for viewing purposes Irfanview scales the image's height by 2 and changes the dpi to *200x196*. It does this to achieve a 'square' pixel. The image that appears on screen now looks roughly how a printer would print it. However, the image data is still the same squished 1752x1077 image.

  • Android, default install location does not have any effect

    I have Just5 Spacer 2 phone running Android 4.4.2 and since I can not root it (the only application I found was supposed to support it was SRS Root, but I only managed to get partial root through it) I thought I'd at least be able to set default install location for applications to external storage, but apparently, despite the fact that adb shows those changes I made, phone continues to install to internal storage.
    [dainis@arch platform-tools]$ ./adb shell pm set-install-location 2
    [dainis@arch platform-tools]$ ./adb shell pm get-install-location
    2[external]
    Any suggestions?

    By digging deeper and deeper I found a few posts/pages somewhere (didn't save sources for some reason) mentioning that this stopped working somewhere at around Gingerbread.
    Those who know - is that true?

  • Does pricing type have any effect in Delivery to billing copy controls

    Hi,
    Does pricing have any effect on delivery to billing copy controls, for example pricing type, since there is no pricing related data in delivery.
    iF the billing is maintained as delivery related billing, will pricing type has any effect.
    Thanks
    Keshi

    Yaa, It is a good question.
    If the billing is maintained as delivery related, its all about the qty of the material to be billed after delivery. (setting maintained at VOV7).
    Even though the delivery doesnt have any pricing relevant data, the pricing type has an important effect.
    Of course it is maintained at delivery to billing copy control, but u have to see where u are finding the pricing type field. It is in the copy control item level for TAN. So it is not relevant to the delivery transaction any more, it is relevant to the item category only.
    So the conclusion here is if the item category is relevant for billing transaction, after delivering the item, how the pricing is carried out during the billing (whether the same pricing or diff. pricing). This is explained by the pricing type field.
    Hope i answers ur query. if u have any further queries, please post.

  • The battery for my macbook pro 13 says "service battery".  Now I want to get a replacement but the reviews for it are horrible! Does anybody have any suggestions?

    The battery for my macbook pro 13 says "service battery".  Now I want to get a replacement but the reviews for it are horrible! Does anybody have any suggestions? I don't want to spend 130 dollars on something I'm going to have to replace in less than a year (which is what normally I been reading)  I do design work and I take my mac everywhere.  Having to always look for a plug or having to be constantly plugged in doesn't sound ideal to me.  Please help me. what should I do???

    Why does it matter if it a scam????? I'll let you figure that out by yourself.  If I'm going to replace it, why should I be contempt with a battery that I have to replace within months (as stated by some people in the comments). The issue here is not if I should or not replace it OBVIOUSLY I'm going to have to before it starts going crazy.  The underlying issue is why is the replacement battery for a lack of better words " a bit crap."  It comes with a 3 month guarantee?? Is that a joke?!??!?! Some people complained it malfunction after only 8- 9 months? I'm sorry but as an Apple fan I think it's absolutely rubbish. I know there is no magic cure I'm just hoping someone shines the light on how crappy this replacement is.

  • Does anyone have any tips on how to maximize battery life of MacBooks ?

    I have just bought the new Macbook 15'' after my older macbook (2009 version) had gone through some issues with its battery. The battery life of my old mac became very short, maybe due to overcharging etc. Therefore I want to make sure I dont make any mistakes this time around and make good use of my battery so that it doesnt get damaged too fast. Does anyone have any tips on how to do this? Or perhaps any MUST NOTs (things that would be harmful to the battery), eg. overcharging?

    Welcome to Apple Support Communities
    Macs do not have overcharging. The battery is stopped being charged when it is full, so do not worry about that.
    The most basic tip is to make regular battery cycles and do not disconnect the MacBook Pro from the charger until the battery is fully charged. Then, if you want, you can use your MacBook plugged in all the time, but remember to make a cycle at least once a month to keep the battery life. Also, do not let your MacBook turn off because its battery ran out of energy.

  • Does Flash Player protected mode / disabling it have any effect on XP?

    Does Flash Player protected mode / disabling it have any effect on XP / Firefox?

    Been experiencing severe slowness and lock-ups with Firefox of late (since 27.0 / 28.0),  which ends with a sudden drop in memory usage and me having to  repeatedly shut it down through Task Manager. I have created a new profile and disabled hardware acceleration. I have tried disabling all  plug-ins and extensions, yet I noticed that at times (not always) plug-in container was still an active process, which I don't understand. Why would it be active when there are no enabled plug-ins? I also noticed that when plug-in container is not active (showing under Processes in Task Manager) I do not have this problem and Firefox runs normally?
    I have run MalwareBytes, TDSSKiller, Hitman Pro and McAfee Stinger - no threats found.

  • HT5627 Does Mail (Mavericks) have any limitations for size, numer of mailboxes, folders, messages, etc.?

    Does Mail (Mavericks) have any limitations for size, numer of mailboxes, folders, messages, etc. ?

    Ah, so you're not considering running OS X Server here, you're running OS X client and asking about the mail client — looks like both the Apple bot that suggested that support article and I were confused.
    Mavericks Mail.app does have a few flakies that I've noticed but does work.  If Mail.app gets confused, restart it and see if it's less confused.  If the accounts get confused and start tossing the password prompt, remove and re-add the accounts.  When re-adding the accounts, don't use the Internet Accounts path, use the Mail > Preferences path.
    Do make a backup or two before the Mavericks upgrade, and most definitely configure and use Time Machine or some other backup tools after the upgrade.
    If you do decide to go to server (which is where I'd thought this question was originally headed), then you can download everything to your own local server — that'll take some add-on software to pull the mail from your ISP, or a set of mail-forwarding rules to push the mail, and some command-line tweaks to relay the mail out (as you're probably on a DHCP dynamic residential IP address), but that'll work, too.

  • HT1726 i have heard that charging less than 80 percent will make the battery lasts longer, does anybody have any idea about that?

    hi,
    i have heard that charging less than 80 percent will make the battery lasts longer, does anybody have any idea about that to help me?

    I don't know where you heard that statement but it's completely incorrect.
    According to Apple:
    Use Your iPad Regularly
    For proper reporting of the battery’s state of charge, be sure to go through at least one charge cycle per month (charging the battery to 100% and then completely running it down).
    Elsewhere, Apple elaborates and explains that two half-discharges (or four quarter-discharges, etc.) equals one full discharge.

    There seems to be a problem, just now, with the USB 3 ports on the new MBP's supporting eternal USB 3 drives. Some people have no luck at all - can't even recognize the drive - and some are reporting USB 2 speeds (those who drives are recognized). I'd call a dealer such as LaCie or OWC to see if they have USB 3 drives that actually work with MBP's with USB 3 ports. You may have to wait for a software/firmware update.
