Think I've made a topic similar to this, but just want to check am doing this right. I use my MacBook unplugged. When it get's to around 10%, maybe less... sometimes it's in the 20's, I plug it to charge. Sometimes I leave it in if am doing intensive work, otherwise, when it's 100% I unplug it. I never let it drain completely so it turns off, though it has once or twice just cuz I couldn't get to my charger. So yeah, am I doing this right? Just wanna make my battery last. I have a late 2011 base model MacBook Pro.
