Q: Mavericks - power use / service battery

Seems like people are reporting that battery warnings go away if Mavericks goes away. Seen reports that going back to SL and warnings disappear. Moving onto Yosemite they also disappear. Annoyed that I shelled out for new battery, which potentially damaged now.

so I charged the battery completely as high as it would charge - left it in that state for a couple of hours...then completely drained the battery until the computer auto powered off...let the computer rest in an battery drained state for at least 12 hours and then reconnected the power and let it recharge.

End result... service battery message has gone.  Coconut Battery reports that the status is now: Good and design capacity has shown a 10% increase.

Will try same method again to see if further improvement.

Exasperating!

So the "service battery" message has reappeared twice if run the machine on battery and let it get very low and then reconnect the power.

The "service battery" message has also gone away again twice if let the battery drain completely, sit overnight then recharge .... the message disappears.

Now going to check it with a second battery.

Slowing losing faith in Apple.

Service battery is back again in my mac after using yosemite for a week. My batter is currently at 50% now, mavericks killed almost 48% of my battery with just around a hundred cycle. SMH

I've let the battery drain completely til computer auto power off, then let it rest for several hours and power up. battery service warning is gone and coconut battery shows the design capacity slowly increasing each time - it's gone up over 13%. If disconnect the power before it reaches 100%, invariably the service battery warning comes back and stays until flatten battery again.

Going to try it with a 2nd battery at some point. How I miss Snow Leopard.

I have MBP 15" late 2011 and I too have noticed the Service Battery notification after installing Mavericks and it drains quicker than before.

Health Information:

  Cycle Count: 365

  Condition: Service Battery

Hopefully Apple will fix this

I just installed Yosemite and the year-long "service battery" message after installing Mavericks disappeared. As many of us here suspected, it likely was a problem with the OS and not the hardware. I'm just amazed that Apple didn't released a Mavericks update and waited to the next OS version to fix it.

Ok, never mind. The service battery message came back one week after installing Yosemite.

Hi,

I too am facing a similar problem, i have an MBP early 2011 model, i upgraded from snow leopard to mavericks and lo and behold my battery life starts dropping like crazy, at the moment i get around 1.5 hours of charge and battery charge has dropped to 22%.

I have tried SMC resets, calibrations.. the whole nine yards but nothing seems to work. I just wanted to know if going back to snow leopard would be a good idea? Has it helped with the battery issues?

Thank You

I want to know if downgrading to 10.6.8 is helping anyone get better battery life? I already downgraded from 10.10 to 10.9 and I think that made a small difference, but really I think what the difference is is setting notification to always be off.

I think my kernel_taks and window server seem to be eating battery.

Macbook Pro (Early 2011)
-Battery cycles: 352

Same thing.  Battery life dropped notoriously after Mavericks, I used to get 7+ hours out of my battery and now it goes down in 1.5-2 hours.

Apple take note and fix this for us, please.

worse still on Yosemite.

Battery drain rate has basically doubled from that of Mavericks (which was already pants). Now get about 1.5 hours of using Wifi / Browser and bluetooth. Used to get 8-9 hours on Snow Leopard with exactly same hardware and usage.

hello everyone,

for all user yosemite have problems battery life you can try this tips. workss perfeccts!!!

This just started happening (or I just started noticing) on my Early 2011 MBP. I never upgraded to Yosemite, hate the look and the new "features" - so I'm still on Mavericks 10.9.4.

Swaps between Service Battery and Normal at a whim, and this is the second battery I've used in this machine.

Not shocked, I decided long ago this would be my last Apple product - but still need to get my money's worth on this one.

That is where off topic, offensive or insulting posts go, we can't go there.
