Yosemite Battery Drain

The installer should handle the optimization itself…mine has optimized through that past series of installs. So far I have not seen battery drain issues with Yosemite, even better use than with Mavericks.

I experience the same issue on my brand new (!!!) mac.

MacBook Pro with Retina Display (15-inch Mid 2014)

OS X Yosemite (10.10) Public version

Hello...I too am experiencing a quicker battery drain on my MacBook Air 13". The upper right hand corner also gets very hot. A fan actually came on at one point...didn't even know the Air had a fan....

Same problem here with my MacBook Air 11" (mid 2014) after installing Yosemite. The battery charges very quickly to 100% but the drains also very fast 😟

Same problem with my MacBookPro11,1: from 9 hours in Mavericks to 3 hours immediately after upgrading to Yosemite 😠

I too have experienced the same problem, the battery drains out very quickly. The previous OS was showing a 100% charged battery to 10+ hrs and I did use it more than 9 hrs without charge, but this one goes out in 4-5 hrs. Is Apple listening to these issues?

Mine seems fine though i have little trouble getting the magsafe port sorted.

Same problem with battery.

Charges fast and also discharges fast.

Same here. My Mid 2013 MBA decreased battery life from 11+ hours to 5 hours 😟

Also, it gets hot easily.

You need to see what application(s) are draining the battery and also check the battery condition.

First hold the option button and click on the Battery icon on the menu bar.

From the drop down list,

• What condition is the battery reporting?
• Are any apps showing up as using significant battery usage?

Also in Applications > Utilities > Activity Monitor - CPU.

What is anything is using high CPU usage, that you would not expect to be doing at the time?

You can sort the CPU% column for highest usage at the top to make this window easier to read.

Any apps that are reporting high battery usage or CPU usage, are you running the latest versions of those apps?

Battery condition "Normal". With CoconutBattery "Good".

No significant battery usage by any of the running programs. Firefox uses from 5% to 10% and WindowServer about 5,5% (peaks to 19%).

And the latest versions are in use.

With Maverick this battery used to last 7-9 hours, but after Yosemite only 2-3 hours.

Same situation here. I have no clue to this decreased battery life.

Even thinking about downgrading to Maverick

All signs that you have incompatible 3rd party software running, running badly. Probably antivirus/cleaning/optimizing or some other fanciful junk. 3rd part peripheral drivers (audio.external input devices etc) are also suspect.

Have you looked to see what is running, and whether it's compatible with 10.10

thanks for the tip. But I have been always checking my activity monitor and haven't found any clue.

CPU usage is generally 6 or 7 per cent.

No strange apps running.

Still, the battery life decreased significantly
