I do use the machine a lot, so understandably the battery has been used quite a bit. coconutBattery claims the battery is "good", I guess for it's age and usage it could be considered normal. Wanted to get a sense of how similar or different my machine is compared to the forum. coconutBattery read out: MacBook Pro Retina, Mid 2012 Model: MacBookPro10,1 Manufacture date: 2012-07-02 --- Battery Details: Manufacturer: SMP Model: bq20z451 Manufacture date: 2012-06-23 Age: 872 Days Loadcycles: 381 Serial: xxx OS X Battery status: Good Battery temperature: 39.5C Battery failure: None Battery usage: 30.5 watts --- Current Charge: 1506mAh Maximum Charge: 7560mAh (19.1%) Design Capacity: 8460mAh (89.1%) --- Does the 89.1% equate to how much of my original capacity I have today? Furthermore, is this a good percentage?
