rMBP Battery

All I see is ijailbreak in the link and it makes me shutter. IMO use the charger as much as you can as a power source depending on how bad your battery life is until there is a software update from apple.

 

The first suggestion in the link is to reset PRAM/NVRAM, which has nothing to do with battery/power/charging issues. Resetting it will not help. Only resetting the SMC addresses such issues.

The 2nd suggestion is to delete the desktop.plist, which also has nothing to do with battery or power issues.

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.

This should answer most, if not all, of your battery/charging questions:
