    The power button change is a new "feature" I think.  If you hold down the control button at the same time as the power button you'll get the old pop up giving you the option to restart/sleep/shutdown.
    As for the battery issue, I'm getting the same problem on my mid 2010 MBP.  Here's what I've noted.

    Prior to the upgrade, and by prior I mean exactly 5 minutes prior, my battery health as indicated by the program Battery Health was showing approx 85% with a max charge of 11162mAh out of a max of 13000mAh after 3.6 years and 143 cycles.  This is consistent with what I have observed for the duration of my use of OS X Lion which I installed on its' release.  Subsequent to my Mavericks installation Battery Health showed the health of my battery @ 74% and a max charge of 9614 mAh out of 13000.  I'm also now seeing the "Service Battery" warning under the current charge menu bar icon. This max charge value has fluctuated over the last few days from a low of about 6000 mAh to around 10400 mAh and the "Service Battery" warning has come, gone, and come back again.  Today,  I noticed that the health and max charge had dropped to about 50% and 6200mAh or so.  Unplugged the charger and ran down to about 85% charge and plugged in again.  My max charge jumped back to 74% and 10200mAh.  I think what's happening is the OS isn't seeing the full potential of the battery correctly.  Of course, there's a big difference in a 100% charge between my usual 11162mAh and the 6000 I saw this morning.  Since the charger shuts off when the charge reaches the point the OS thinks the battery is charged to it's max, there's no way to get past that point.  As I was charging again, and noticed that it was indicating a max available charge of 10400mAh, I also noticed that at 99% charge, the time to full charge indicated 0:00, but yet it continued to charge until it reached the 10400 mAh.  I know of at least one person who had a similar problem and he indicated that a reinstall of Mavericks may have solved the issue for him.  I've yet to try that, but it might be worth a shot.

    3-1/2 year old mid-2009 13" MBP here with a SSD instead of the stock mechanical HD and after upgrading to Mavericks, I started seeing the Service Battery message for the first time and now I see that the battery capacity and life has really taken a hit.


    I've been off the charger for about 45 minutes after it presumably being fully charged from being plugged in all day and it's down to 63% and 2:03 remaining. Unreal. Battery stats below:


    Charge Information:

      Charge Remaining (mAh):    2646

      Fully Charged:    No

      Charging:    No

      Full Charge Capacity (mAh):    4095

      Health Information:

      Cycle Count:    252

      Condition:    Service Battery

    UPDATE: 70 minutes off charger, now showing 50% and 1:20 remaining. Pathetic.

  • AvgJoeRepair Level 1 Level 1

    same issue here

    updated to Mavricks my battery life at full charge is 2:00 hours and says service battery!

    down graded back to moutian lion full charge gives me 5:00 + hours and battery is in good condition with only 145 cicles on it, and all my apps work

    on mavricks more then half my apps that i use for work no longer even start up

    Im just happy that i copy my os before the update

    Kind of glad to see I am not the only one having this issue.  Right before the update, I had no battery issues, right afterwards, service battery.  On top of that, my system seems a little slower.

  • jmrossy Level 1 Level 1

    I've also seen a significant drop in battery performance.

    What's ridiculous is that I have a 2013 Macbook Air that is 3 months old. Before the update, the battery would last an amazing 10 hours or so. Now 5 or less. I have tried to diagnose the problem using Instruments, but there aren't any obvious culprits.

    I have had this issue too but, it seems to go away after a restart. Check your activity monitor and see if the Kernal_root is taking up a lot of memory. That's what I found as the problem.

    same thing reported after Snow Leopard, Lion, Mountain Lion and now Mavericks. But only happening to a few people. No change in my battery life on three MacBook Pros. Check your activity monitor.



  • Hitz86 Level 1 Level 1

    +1 for the service battery message.


    Running a Mid 2012 13" MacBook Air, never seen the warning before. Fewer than 400 cycles.

  • ervalerio Level 1 Level 1

    I've a 2012 rMBP. Before the update to 10.9, my battery (173 cycles, 94%) use to last 7/8 hours.

    Now, with 70% of battery charge remaining, it only gives me 2:56 of battery life.

    The upgrade also borked the power/restart button. Pressing it now causes the screen to go blank for a few seconds, but the shutdown/restart dialog never appears.

    Power button behavior was specifically changed in Mavericks. Pressing it puts the display to sleep (same as Shift-Ctrl-Eject on machines with an Eject button), a long press (~1.5s) or pressing Ctrl + Power will pop up the shutdown/restart dialog and a very long press (~5s) will do an immediate forced shutdown.

    Same issue here. Macbook unibody 2008.


    Service battery warning showed up after Mavericks update.

  • George Lucchese Level 1 Level 1

    I am having a similar issue with my 2010 Macbook Pro, though to be fair they may have been occurring prior, I just never checked the power menu before Mavericks. It sounds like there may be some issue with the way Mavericks is detecting battery history. Maybe it reset the previous configuration? I wonder if a few cycles will resolve some of the battery capacity measurement issues.

  • skullbuster Level 1 Level 1

    I am having the same issue. After I updated to Mavericks, I had the "Service battery, Battery is charged." warning in the energy saver settings. It was fine before the upgrade. Below is my battery info.
