    Hi everyone, im on the process of calibrating my battery, but i have a question. When i let my mac run on battery power until it goes to sleep, does that means i have lo let it drain in one session without turning it off?

    thanks

    Not sure what you mean by "calibrating" your battery. If this is a li-ion battery that we are talking about, there isn't any particular action that you need take. Li-ion batteries are not subject to "memory" problems and will perform at their peak capacity regardless of their level of charge. Don't worry about what the charge level is when you put it back on the charger--it is not affected by that. Previous battery types were buy li-ion solved those problems.

    The only issue that li-ion batteries that is a limited lifespan, which is generally 1.5-2 years if you use the laptop every day and charge it frequently. There isn't any method you can perform or hoops to jump through that will change that either.

    While it doesn't explain all the nitty gritty details about batteries, it does state that "calibrating" your battery just resets the meter in detecting how much charge is remaining. It's not something you need to do much, if at all. As cjcerny states, batteries tend to die out after about 2 years or so of frequent use.
