    I bought a rMBP last year in February and my cycle count is 257. Is that bad? I usually use my macbook unplugged and charge it once or twice a day to full capacity. Should I worry about the battery deteriorating quickly over time? Is the cycle count too high for only having the laptop for a year?

    Your cycle count is about average (a charge every 1.4 days).


    I've reached about 1100 cycles on my 2010 MBA after 4 years of use.


    Your battery will degrade at roughly 7% per year, though i have found this figure increases exponentially each passing year (i had 50% remaining on my MBA after these 4 years).

    Whatever you do, the battery will degrade, so you'd best just enjoy the experience and if it comes to it, you can change the battery later on. Never mind the cycles because worse than the cycles is keeping your battery at full charge at all times.

    If you want to absolutely extend your battery life:

    1. Use the battery from time to time.

    2. Keep it away from heat.

    3. Store it at between 40 - 60% charge if you won't be using it for an extended period of time.

    4. Avoid depleting the battery completely.
