i bought macbook air in late 2013. first macbook, , satisfied it. battery life great, great.
after 1 year warranty gone (for premium product, consider warranty bit less), problems started. battery sits @ 81-82% health, right after warranty over. can 4 hours of normal usage (web browsing safari).
not know in situation, there way in can calibrate battery? first , last time when bought apple product. student, tried save money in order laptop after problems have had dell laptops, seems apple products suffer same issues, , have less warranty too.
battery life extremely important me, , thought buy laptop function advertised (for number of 1000 cycles, battery should not go below 80%. did not go below 80%, sits @ 82% , performance weak in opinion)
sorry apple, nice use products, me , friends not going buy them anymore, unfortunately.
hope can find solution in order calibrate it, or something. not want pay replacement battery, because instead of doing sell laptop , 1 windows on it. pity barely afford this, , did not met expectations.

i have external monitor (nec pa271w) has custom calibrated profile. problem i'm having whenever i'm on safari , use magic trackpad go previous page colors off while page reloads. once it's loaded colors go custom profile. after lot of reading found out if set system preferences - display - color srgb iec61966-2.1 colors match , page reloads faster. here's example of i'm seeing while go 2 finger gesture. issue happens using coverflow in finder. has experienced same issues on external monitor? driving me crazy Forums Macs Mac Accessories iPhone Mac OS & System Software iPad Apple Watch Notebooks iTunes Apple ID iCloud Desktop Computers Apple Music Professional Applications iPod iWork Apple TV iLife Wireless
okay, know how battery cycles , work. want know is: how many cycles battery has how old battery is how many mah macbook shipped with how many mah have now reading thread on different site macbook batteries , commenting battery info. of them commenting saying reached 120 cycles per year. 1 guy said mac 3 years old on 250 cycles (avg. 83 year). think person had 400 after 2 years. in 'system information' says age of macbook 3 months old (when arrived said 1 months old, i've had 2 months) , have 98 cycles, using many cycles? i'm asking because realised apple batteries more or less useless @ holding charge after 1000 cycles , if i'm averaging 100 every 2 months gives me 1.7 years until macbook more or less desktop... to me seems poor previous windows laptops owned lasted long , expect lot more machine on £1k. (i have been told batteries in newer macbooks glued in place , replacing battery hard job , cost lots of money, mistake...
