Significant decrease in battery life-Macbook Air HELP

Hello.

My macbook is less than a year old (10 months to be exact) and my macbook air has been great

Recently i can feel the battery been decreasing faster than usual. Usually if i just surf the net i wont lose as much battery but within 1 hour i lost almost 20 percent
I dont think this is normal and would love if i got any help or assistance


Many thanks

🙂

MacBook Air, OS X Yosemite (10.10.2)

1. Check the cycle count of the battery against the rated life for your model. The battery may be due for replacement. If the power adapter is connected almost all the time, the battery may need replacing even though the cycle count is not too high.

2. Follow these instructions.

3. In the Energy Saver preference pane, uncheck the box marked

Enable Power Nap while on battery power

if it's shown (it may not be.)

4. You can also try resetting the SMC.

5. Make sure your system is up to date in Software Update.

6. Make a "Genius" appointment at an Apple Store, or go to another authorized service center.

So it is not the battery but something that's gone astray.

Did you do the reset already:

1. double click the Home button, slide all running softwares up to stop them.

2. hold the Home Button and the Power Button at the same time, keep holding until you see the white apple logo appear (about 10-20 secs), then let both go. Let it start up.

Back up all data before proceeding.

Triple-click anywhere in the line below on this page to select it:

/Library/Caches/com.apple.SoftwareUpdate

Right-click or control-click the highlighted line and select

Services Reveal in Finder (or just Reveal)

from the contextual menu.* A folder should open with an item selected. Move the selected item to the Trash. You may be prompted for your administrator login password. Restart the computer and empty the Trash.

*If you don't see the contextual menu item, copy the selected text to the Clipboard by pressing the key combination command-C. In the Finder, select

Go Go to Folder...

from the menu bar and paste into the box that opens by pressing command-V. You won't see what you pasted because a line break is included. Press return.
