Battery life issues on Macbook Air 2013

What is the estimated time remaining with absolutely nothing running?

I have a workload many times heavier than Apple's test and get 7-8 hours.

You should get much more than 6 - 7 hours of battery life with a new MacBook Air.

Read: Mac notebooks: All about batteries

Also: Runaway applications can shorten battery runtime, affect performance, and increase heat and fan activity

If you use Google Chrome, don't. Safari 7 is both faster and much more power efficient.

Power problems justify an SMC reset. Read the procedure carefully: Reset the SMC.

Consider updating OS X to Mavericks. It's free.

.

The above MacBook Air is over two years old with nearly 200 battery cycles, but it is enjoying a 23% increase in battery life just from having upgraded to Mavericks from Mountain Lion.

Of course your MBA is new, but upgrading to Mavericks is like getting a brand new Mac for free.

If none of the above helps please write back for troubleshooting steps.

After Mavericks install, your "time remaining" WILL BE INACCURATE until you do a SMC reset in many case

SMC reset

1. Shut down the computer.
2. Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
3. On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
4. Release all the keys and the power button at the same time.
5. Press the power button to turn on the computer.
   

There is a HUGE distinction here about someone getting less batt. life in actuality .......or are they just reading the "time remaining" and using that as a true indicator which is certainly is not.

Ive seen 3 notebooks after SMC reset jump 4+ hours in "time remaining" and slowly climb after 3+ full charge cycles.

Until things settle down, nobody should trust what the 'time remaining' says.

DO AN SMC RESET!! LIKE PlotinusVeritas SAID!!! I WENT FROM 8:35 TO 9 HOURS, NOW IM AT 16 TO 19 HOURS OF REMAINING BATTERY LIFE!! THAT WORKED AWESOME!!

Lucky you, I only get 4:07 with 100%, and that's when I'm using nothing. Help anyone? 😕

I'm having a similar problem (theKingofChaos) . Mine was showing 6hrs with a full charge, I timed it, and it lasted for about 6hrs.

I just did a fresh install and have nothing running. I saw --- 9hrs @ 100% --- 8:52 @ 98% --- 7:45 @ 96%,

The problem is that it went from 100% to 96% in the last 25 minutes while on the phone with Apple Support...

Now 7:35hrs @ 95% (While typing this... on another computer while the MBA sits with no apps open, and "No Apps Using Significant Energy", and Spotlight is not indexing...)
