    Hi

    My Macbook 12" 2015 battery is at 43.6% design capacity(2296mah out of 5297 mah) after 320 cycles. Battery manufacture date is May 5, 2015 and laptop was made on June 8, 2016. I have periodic issues with charging the battery to full and OS Sierra says I should "SERVICE BATTERY". Earlier today it could not charge past 75% and was showing battery drain even with the charger plugged in.

    I still have about 7 months on Applecare and would like to know if I need to wipe all my personal data(Filevault is on) before handing it over to Apple. Does Apple need to have access to the OS for the repair?

    and for those who have had the battery replaced, do you know if the battery replacement will be covered as this seems to be premature wear. My macbook 13" 2011 still has about 80% battery capacity.

    I am setting up a genius appointment for this Thursday and would like to be prepared before arriving.

    Thanks.

    I haven't had my battery replaced, but the official word from Apple is that after 1,000 cycles, the battery should be at 80% maximum capacity. Clearly your battery is faulty and should be covered.

    OS access is not required, no. However, I recommend having a backup of all your data. Apple won't spy on your existing data, but I have heard reports of them wiping SSDs/HDDs for no strictly required reason during repairs

    "CLEARLY" is not a word Apple Geniuses seem to understand when it comes to these issues based on my experience.

    Everytime I go for what "Clearly" is a battery issue they try to play games when I tell them it is within apple's own specs such as you stated.

    Usually ending up arguing with manager.

    This has been going on since I got the 3g to most recently the 6s+. Battery on the 3g crapped out 18 months and wouldn't hold charge. Battery on the 6s+ dipped below 80% at about the same time(IIRC 60% design capacity)

    Spoke to Apple over the phone and they cleared it as a replacement under warranty. I wiped the phone as instructed and when I got there apple genius started arguing that since I wiped the phone I had to come back after a week because wiping the phone cleared the stats usage for the battery. I escalated to manager who grudgingly replaced the phone.

    They act like you are trying to pull a fast one when the batteries consistently fall short of their own specs.

    Which is insulting as I have 10 apple devices in my household(2 laptops, 5 phones(3 active), 2 ipads, watch) and the biggest issue I have with their devices is the battery longevity.

    I have a MB Pro 2015 which still has 6 months of Applecare left. It's at 82% with 750 cycles. Likely to drop below 80 by the time it reaches 1000 cycles. Are they bound to do a battery replacement free?

    I've never had battery issues myself (mine is at 96% 400 cycles), but as I understand it, yes
