MacBook – New MBP 13 retina late 2013 battery problem

I can see two main possibilities:

1. Apps like FolderCloser, NoLockScreen, and SBSettings shorten battery life by requiring heavy background processes. The only solution to this would be either to not install these apps or restore the phone to its original state altogether (and not have these apps installed). I am convinced that jailbreaking allows for processes that are not in phase with Apple's careful thriftiness of battery use.

2. Your battery is not calibrated properly so your iPhone miscalculates the remaining percentage. The solution here would be to drain your battery completely and then fully charge it.

Good luck! And know that you can restore the phone to its original state.

Open a support ticket with AppleCare if you'd like expert help in determining whether they can run diagnostics remotely to measure a few more data points than the overall summary.

It could be a high GPU / CPU / firmware thing that needs updating, but it also could be a battery that soon enough will show less life than designed and you'll be offered an exchange under warranty.

You can also open terminal and issue a few commands to look in more detail at power management.

 pmset -g rawlog

 pmset -g pslog

If you record the settings you have, correlate things with date; io_stat 300 you should get a good indication if the estimates are off and why. Of course, start with the machine 80% charged or more and let them run as your battery drains. AppleCare might not need all the logs, but you can send them / save them and run a check in 3 or 6 months to see if the battery is substantially worse / same / better than now.
