Macbook pro Late 2013 retina display battery questions and issues

Hi,

So I was a bit suspicious about my macbook pro 2013 13 inch retina display models battery, its the latest macbook pro 13 inch. The website says that it will last for 9 hours but mines lasted for only 6.19 hours. All the apps I used were probably Xcode (doing coding projects), Photoshop, Safari and Notes. I did keep the brightness high and also had bluetooth on for a while. Is this a good battery life for my mac or should I go back to the Apple Store and tell them to fix my battery?

I have all the battery logs below:

Standby Time: 1:13 PM

Battery Percent: 90%

Usage Time Starting: 3:10 PM Battery Percent: 87%

Usage Time Ending: 4:01 PM Battery Percent: 75%

Fayk1,

carefully review that Web site’s claim; under what conditions does it claim that a charge would last for up to nine hours? (Note those key words — “up to”.) Did your conditions exactly match those conditions? If you want a charge to last as long as possible, then make the display as dim as you can stand it, and minimize your use of Bluetooth and energy-hungry apps like Photoshop and Xcode compilers. To maximize the battery’s life, start recharging it when it gets down to 20%.

Ah ok, but there still is an unanswered question, is 6 hours of battery this is in complete usage no standby involved a good battery life for my mac or should I return it and get int fixed? Thanks for your reply by the way.

Fayk1,

different tasks require different amounts of power. Given your particular mix of app usage and your display’s high brightness, I’d guess that six hours would be a reasonable charge duration, and that nothing would need to be fixed.
