Mavericks - power use / service battery

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.

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.

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.

+1 for the service battery message.

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

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.

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.

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.

Charge Information:

Charge Remaining (mAh): 10273

Fully Charged: Yes

Charging: No

Full Charge Capacity (mAh): 10304

Health Information:

Cycle Count: 94

Condition: Service Battery

Battery Installed: Yes

Amperage (mA): 0

Voltage (mV): 8258

Same problem here after upgrade to Mavericks MBP 13 Mid 2010 552 Cycles

same here, "Service Battery" message & radical drop in battery health since updating 6 days ago... MBA Mid 2011… 553 cycles
