Yesterday, PetSugar asked me a great question — how can she extend the life of the battery in her new MacBook Air? I gave her some of my "battery-saving" tips, but I didn't know if her notebook should be plugged in all day when it's turned off (and fully charged) — something she was concerned about, and something I do all of the time. Keep reading to find out the answers to some of the most popular MacBook battery conundrums.
- When you first receive your MacBook, make sure you fully charge the battery before use.
- MacBooks use lithium ion batteries, which means they don't have to be completely drained to prevent the memory effect. Completely running them out actually reduces their capacity.
- According to Apple, it's important to keep the electrons in the battery moving occasionally, but it does not recommend leaving your laptop plugged in all the time.
- Basically, it's best to keep your battery's juices flowing. Therefore, if you use it on the bus on the way to work, then plug it in all day while at work; that's actually good for it.
To see more MacBook battery-saving tips, just
- If you don't use your MacBook regularly, you should set a reminder to charge and discharge the battery at least once per month.
- And if you are away for more than six months, Apple recommends storing your battery in a cool place with a 50 percent charge. Therefore, completely shut it down with a 50 percent charge, since sleep mode still uses power from the battery to maintain your laptop's memory.
- Apple periodically releases updates that may improve battery performance, so make sure you install the updates!
