What happened to it to warrant this battery replacement? My Macbook Air is over 4 years old and finally needs a new battery, so what made you think the battery was bad or whatever is happening here? It is a pain in the ass to tear the whole thing down and replace the top case. So if they are replacing the battery, I would assume that is all they are replacing. The battery is just a big ol' multi cell battery inside the Macbook. The "palmrest" is the top case, it is the keyboard as well as all the stuff around it, minus the trackpad. If coconutBattery says that your battery has 50% of its original capacity then a replacement might be in order, but if it says you have 80% of the original capacity, and if some piece of software shows up as using a lot of power in the "CPU" and "Energy" tabs of Activity Monitor, then that'll be your problem. coconutBattery can help you diagnose that by giving your battery's current maximum charge as a percentage of its original charge. If your computer does have something going on that's making it heat up - whether that's software (runaway process using lots of CPU or whatever) or hardware (too much dust in the fans, etc.) - then that can make it use more power, causing the battery life be worse than it should. The free app coconutBattery is another way to see that information as well as a bit more.įor whatever it's worth, although a 6.5 -> 3.5 hour decline in battery life isn't out of the question for a three year-old computer that's seen a lot of use, if it's only been noticeable in the last few weeks, along with the computer running hot, that'd suggest there's something else going on. You can find that information by going to System Information (in the Utilities folder) and looking at the "Power" tab, which should give you information about the battery's cycle count, general health and charge.
