Frequently Asked Questions About MacBook Batteries

Figuring Out Why Your MacBook Battery Drains At Night

Is your MacBook battery draining at night? This is probably due to a piece of software on your Mac that is misbehaving and waking it while it should be sleeping. There are several ways to figure out which could be the culprit. You can use various tools to compile a list of suspects and then quit those before putting your MacBook to sleep to test them. You can also try things like reseting parts of the system and trying safe mode. You may be able to figure out the problem on your own, or you may need to take it to an expert.

Comparing Magnetic Power Adapters for USB-C MacBooks
MacBook users miss the old MagSafe power adapters. Third-party products offer an alternative in the age of USB-C power cables. You insert one part into your MacBook and leave it there, and the other part connects to it magnetically. However, since they stick out somewhat, people are afraid that they could inadvertently damage their MacBooks if they catch that edge on something. I take a look at three popular magnetic power adapters for the MacBook and MacBook Pro and compare them.
Turning On Or Off the MacBook Power Chime
On many recent MacBook models you will get an audible chime when you plug the machine into power. But if you have one of the models where this is not on by default, you can use a Terminal command to turn it on. If you'd rather not hear this sound when you plug in your MacBook, you can also disable it.
Uninterruptible Power Supplies
Next to a back drive, a UPS is the most important accessory you need if you own an iMac, Mac mini or Mac Pro. Essentially a power strip with a battery, a UPS will keep your Mac running if you have a power outage or even a split-second power interruption. Then you can shut down your Mac gracefully and not lose any work. Most UPSes today come with a USB connection that you can connect to your Mac. Then you get a new section in System Preferences where you can set your Mac to shut down on its own if power is out and the battery is in use.
