hi i've done research , aware unibody mbp not need battery calibration, altho have read sites state calibration maybe needed first time brand new mbps, guess debatable?
anyways in case had replace mid 2012 battery because died on me, bought new battery apple , replaced myself, has 69 cycles thought of calibration came mind, since battery replacement, , system , battery someway/somehow need calibrated proper reading. battery health fluctuates between 93% - 92% average fcc of 5350mah. previous battery had 650 cycles , held consistent health of 96%.
question is, procedures in calibrating battery unibody? follow same steps mbp replaceable batteries?
no, it's not debatable. built-in batteries in newer mac unibody notebooks come pre-calibrated , do not require regular calibration removable batteries in older apple notebooks.
your battery fine. normal if battery health (maximum capacity) more or less 100%, when brand new, or if fluctuates or down on time. gradual decline not in straight line downward, , may decline more rapidly @ times , slower @ others. further details, read checking status , health section of following link.
no, don't need calibrate battery.
link below should answer most, if not all, of battery/charging questions, including tips maximizing battery performance. if haven’t done so, highly recommend take time read it.
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...
i have mbp 17 2010, equipped vertex 2 ssd 120gb boot disk. it's old hardware don't want change it, problem ssd performing poorly : ssd health report not bad (except temperature, dont understand) : sata link looks ok : efi version latest : speed, write speed, quite half of vertex 2 public benchmarks. ? rododendro said: ↑ i have mbp 17 2010, equipped vertex 2 ssd 120gb boot disk. it's old hardware don't want change it, problem ssd performing poorly : speed, write speed, quite half of vertex 2 public benchmarks. ? click expand... did ssd slow down on time, or first time tested it? of ocz ssds era used sandforce controller, uses compression techniques achieve it's advertised performance. blackmagic speed test (and many real world applications) use binary/incompressib...
