I've had my 2012 rMBP since it's launch. Its battery has 430 cycle and I've made sure to keep it charged and drained to no less than 30% to keep it maintained. However, the battery health indicator shows that it has 79% rating. It once lasted for around 6-8 hours, and now it lasts only 4-5 hours. To anyone who also have low cycle, how is your battery doing? If you also have a good info on 3rd party battery, please share!!! I also heard some people got their battery replaced by Apple with no cost as an "exemption", due to "statutory" promise that the batteries will last 80% up to 1000 charges. I believe that statutory law also has its place in the U.S. (I live in California). Anyone has experience similar to these people?
