Seven hours battery normal?

[gadgetgirl85]

I bought a late 2013 rMBP about 2 months ago. I was getting more like 9 hours battery now I'm getting around 7. Is this normal? I checked activity monitor and doesn't seem like there are any apps draining the battery.

There are many factors that impact your battery life. See the BATTERY LIFE FROM A CHARGE section of the following link for details, including tips on how to maximize your battery life.

The link below should answer most, if not all, of your battery/charging questions. If you haven't already done so, I highly recommend you take the time to read it.

I have read it, several times. Still doesn't answer me.

As stated in the FAQ, it depends on your workload and settings (brightness, Wi-Fi, Bluetooth, etc.). You won't always get the maximum life from a charge. It will vary moment-to-moment, based on the power demands at any given point in time. There's no such thing as "normal", as it varies widely from one machine to the other.

Then:

9hrs actual or 9hrs indicated by OSX or an app?

Now:

7hrs actual or 7hrs indicated by OSX or an app?

There will always be less going on on a fresh MBP (once Spotlight has completed its initial run), syncing/cloud apps are a good usage of battery without realizing it.

Post your energy usage and/or Option-click on the battery indicator in the menubar, what shows as using energy?

7hrs is well within a normal range. So is 9hrs (thats pretty good actually)

Only showing safari? Should I use a different browser?

Nope - Safari is about the best for battery life, I would suggest you install the Click-to-Flash extension to prevent tabs running Flash without you knowing.

What does the Energy Usage tab in the Activity Monitor show? What is your screen brightness set to?

 

[gadgetgirl85]

That safari is 22? I'll try installing that extension. I've just decreased my screen brightness slowly so will see how that goes. Thanks 🙂

Oh I remember the days with my 2008 unibody when I was happy to get almost 3 hours before I had to stop and use my spare battery to continue working...
