Hi, I use my MBP all the time as I work on it and go online at night too. I have had it 10 months and have 228 load cycles. I checked my battery health earlier and it was at 87%..not great, but manageable but I just checked now and it's gone from 87% down to 47%?!?! How is that possible. I have Apple Care, but I live in Turkey and although they have Apple Stores here, they don't replace batteries or do any repairs, everything gets sent to a different country so I'm told. I've done the thing suggested on Apple's site where you should run the battery down completely and then leave it for 5 hours and then fully charge, at least once a month so what am I doing wrong? Is 47% normal for a 10 month old MBP?
