    I just bought the new MBP 13'' (late 2011). I installed an app and it shows
    that my battery health is 89%. I've only used my MBP for 1-2 weeks. Is it normal? What is more, how long does a 13'' MBP last in general use?

    P.S. I will go for a trip and it will last 5-6 hours. Will my MBP last the whole trip for watching movies with a single full charge?

    Thank you in advance.

    It is perfectly normal if your battery health (maximum capacity) is less than 100%, although 89% is lower than would be expected after only 2 weeks. It will fluctuate both up and down over time. For further details, read the CHECKING STATUS AND HEALTH section of the following link.

    There are many factors that impact your battery life. See the BATTERY LIFE FROM A CHARGE section of the following link for details.

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