[QUOTE="ticedoff8, post: 959890, member: 117762"] Batteries are not precision instruments. Just because the OS has a digital readout of "percentage" of battery capacity doesn't really mean anything. It is a rough estimate at best. It is like a digital watch that reads 1:38:45pm when it is in fact 10am. It is very precise, and very wrong. Without some outside reference or context, the digital read out of the watch (or the OS's estimate of battery capacity) can be meaningless. I wish everyone would take a deep breath when thinking about batteries. I think it is ridiculous when someone posts something about their batteries "losing 3% in the first two weeks" - is that 5 minutes of use? 10min? 30 seconds? How do they know? These batteries are designed to last about 3 years in normal use cases. More than that and you are the fringe use case - same for less than 3 years. That's why they have 1 to 2 year warrantees. The battery in my MBP lasted 4 years - and I replaced it because it was down to 45 min of run time. I never did any calibrations or charge cycles or anything special. I just used it like I wanted to use it until it wouldn't do what I wanted anymore. [/QUOTE]
