10 Simple Ways to Improve Your MacBook’s Battery Life

We’ll tell you what to do to get more hours out of your trusty MacBook.

Apple’s current crop of MacBooks based on the company’s own M1 and M2 processors have better battery life than the previous Intel-based machines, but there are still some easy ways to extend your MacBook’s running time. If you’d like to improve the battery life, we’re here to say you don’t have to trail a bulky charger just to get through the day (although ancient laptop batteries may legitimately need to be replaced).

For most people, you can take a few minutes to adjust some settings to extend your laptop’s battery. Below, we’ll show you how to check its health, as well as cover tips like reducing keyboard and display brightness. We also make the case for using the Safari browser over Chrome.

Check your MacBook’s battery percentage

Keeping an eye on the remaining battery life won’t make it last any longer, but it can help you plot out how much work you can get done before you need to recharge. Click on the battery icon in the menu bar to see how the percentage of battery remaining. And if you’re running on AC power, it will give you an estimate for how long you need to continue charging the battery to bring it back 100% charged.

Here you can also see which apps, if any, are causing significant battery drain.

ou can see a lot of information just by clicking on the battery icon in the menu bar.

Check your MacBook’s battery health

Whether you buy a refurbished MacBook or you’ve been trying to squeeze every last ounce of life out of your aging MacBook, it’s a good idea to check your battery’s overall health. MacOS includes a tool that will tell you its potential capacity, and if you need to have it replaced.

To view your battery’s health report, click the battery icon in the menu bar, then select Battery Preferences. Next, make sure the Battery tab on the left side of the window is selected then click Battery Health. A window will pop up showing you the current condition as well as the max capacity. If you have questions or want to know more about what the status means, click the Learn More button to open an Apple support page that’s specific to your MacBook’s processor (Intel or Apple Silicon).

For those who want more insight into their MacBook’s battery history, you can view the number of charge cycles the battery has gone through. Click on the Apple icon in the upper-left corner, and then while holding in the Option key on your keyboard, click System Information. The System Information app will open, where you then need to find and select the Power section, and then look for Health Information. There you’ll see your battery’s health, capacity level and cycle count. For reference, check out Apple’s chart of the expected battery cycles. Most newer MacBook batteries have an expected life of 1,000 charge cycles, after which Apple suggests getting your battery replaced.

Optimize battery charging

If your MacBook is going to spend most of its time plugged in, you’ll definitely want to change this setting. MacOS can learn your charging habits to reduce battery aging. Click on the battery icon on the menu bar at the top of your display and select Battery Preferences from the drop-down menu as mentioned earlier. At the bottom of the list of options, select Optimized battery charging. This will slow down your charging once the battery hits 80%.

Save battery by dimming your display, optimize video streaming

Powering the display is the biggest drain on battery resources. So, first things first: Lower the brightness of your display to a level that’s comfortable for your eyes. The brighter your display, the shorter your battery life. You can also set the display to dim slightly on battery power and to shut off after a period of inactivity by going back to Battery Preferences.

There’s an option to slightly dim the screen when you’re on battery power, and to reduce battery drain when streaming video on battery power. I also suggest customizing how long your display will remain on to as short of an amount of time as you can. That way when your attention is elsewhere, your MacBook’s screen turns off completely, saving precious battery life.

Apple’s M1 MacBooks have crazy battery life, but you can always tweak it.

Kill keyboard backlights when not needed

A backlit keyboard is great for typing in the dark, but it can also drain your battery. You can set the keyboard backlights to turn off after a period of inactivity so that they’re on when you need them and off when you step away. Go to System Preferences > Keyboard. On the Keyboard tab, check the box for Turn keyboard backlight off after [X secs/min] of inactivity. Your options range from 5 seconds to 5 minutes.

I also suggest checking the box next to Adjust keyboard brightness in low light to ensure your custom brightness controls are preserved, regardless of how dim or bright the area you’re working in is.

Every little bit helps, right?

Turn off Bluetooth if you’re not using it

There is a good chance you won’t be carrying around a Bluetooth mouse or speaker when you leave your desk. With nothing to connect to, there is no point in having Bluetooth enabled. I recommend disabling the radio to conserve battery. Just click the Control Center icon in the menu bar, then click Bluetooth and click the switch to slide it to the Off position.

The only potential downside with disabling Bluetooth is that Apple’s Continuity feature, which allows you to quickly and easily share information between your iPhone or iPad and Mac, won’t work.

Consider switching from Chrome

If Chrome your main web browser, you might consider making the switch to Apple’s Safari browser. Chrome is a known resource hog, taking up precious memory, and by extension eating into a laptop’s battery life.

Apple’s battery life estimates for its MacBooks are calculated with Safari as the default web browser. If you’ve never used Safari as means to get around the web, you’ll be surprised at how capable it is. I personally use it as my main browser and rarely run into any issues, which wasn’t the case just a few short years ago.

Chrome can use more than its fair share of battery resources.

Keep current with software updates

Staying current with MacOS updates will help you get the best possible battery life. To check to see if an update is available for your MacBook, go to System Preferences > Software Update. While you’re there, check the box to Automatically keep my Mac up to date, and clicking the Advanced button will let you check for updates automatically, download them automatically or install them automatically.

Quit applications you’re no longer using

It’s best to close programs when you are done using them. This can be done by pressing the Command and Q keys at the same time, or click the program name in the menu bar and selecting the Quit option. To see how much energy each of your open applications is using, open the Activity Monitor and click the Energy tab or click the Battery icon in the menu bar.

Disconnect accessories after you’re done with them

As with Bluetooth, if you aren’t actively using a USB-connected device (such as a flash drive), you should unplug it to prevent battery drain. If the power cord isn’t connected, charging your smartphone or tablet via the MacBook’s USB port will also drain your battery.

If you’re looking for ways to get better performance out of your Mac, we have your back. We also have a long list of MacOS features that are easy to forget, but you need to know about. Before you forget, make sure to start backing up your Mac.

Get Ready for a Striking Aurora That Could Also Disrupt Radio Communications

Don’t expect the storm to cause a lingering problem, though.

A geomagnetic storm is threatening radio communications Monday night, but that doesn’t mean you should be concerned. In fact, it may be an opportunity to see a colorful aurora in the night sky.

The National Oceanic and Atmospheric Administration has issued a geomagnetic storm watch after witnessing a coronal mass ejection from the sun on Saturday. The watch, which was issued over the weekend and will expire after Monday, said the onset of the storm passing over Earth on Sunday night represented a «moderate» threat to communications. As the storm continues to pass through, it could deliver a «strong» threat on Monday night that could cause radio communications to be temporarily disrupted during the worst of it.

Even so, NOAA said, «the general public should not be concerned.»

A coronal mass ejection occurs when magnetic field and plasma mass are violently expelled from the sun’s corona, or the outermost portion of the sun’s atmosphere. In the vast majority of cases, the ejection occurs with no real threat to Earth. However, in the event the ejection happens in the planet’s direction, a geomagnetic storm occurs, and the Earth’s magnetic field is temporarily affected.

In most cases, geomagnetic storms cause little to no disruption on Earth, with radio communications and satellites affected most often. In extreme cases, a geomagnetic storm can cause significant and potentially life-threatening power outages — a prospect that, luckily, the planet hasn’t faced.

Switching poles

Every 11 years, the sun’s magnetic poles switch, with the north pole and south pole swapping positions. During those cycles, the sun’s activity ramps up as it gets closer to pole-switching time. The height of its activity is called solar maximum, and scientists believe we either may be entering the solar maximum or may be already in it.

During periods of heightened solar activity, sunspots increase on the sun and there’s an increase in coronal mass ejections, among other phenomena. According to NOAA, solar maximum could extend into October of this year before the sun’s activity calms and it works towards its less-active phase, solar minimum.

Even when geomagnetic storms hit Earth and disrupt communications, the effects are usually short-lived. Those most affected, including power grid operators and pilots and air traffic controllers communicating over long distances, have fail-safe technologies and backup communications to ensure operational continuity.

But geomagnetic storms aren’t only about radios. In most cases, they also present unique opportunities to see auroras in the night sky. When the storms hit, the plasma they carry creates a jaw-dropping aurora, illuminating the night sky with brilliant colors. Those auroras can be especially pronounced during the most intense phases of the storm, making for nice stargazing.

If you’re interested in seeing the aurora, you’ll need to be ready. The NOAA said the «brunt of the storm has passed» and even if it lingers into Tuesday, there won’t be much to see after Monday night.

Last Total Solar Eclipse for 20 Years Is Coming: How to See and Photograph It

It’s your last chance until 2044.

Get your eclipse glasses ready, Skygazers: the Great American Eclipse is on its way. On April 8, there’ll be a total eclipse over North America, the last one until 2044.

A total solar eclipse happens when the moon passes between the Earth and the sun, blocking the sun and turning an otherwise sunny day to darkness for a short period of time. Depending on the angle at which you’re viewing the eclipse, you may see the sun completely shrouded by the moon (called totality) or some variation of it. The more off-angle you are and the further you are from the path of the eclipse, the less likely you’ll be to see the totality.

The 2024 total solar eclipse will happen on Monday, April 8. The Great American Eclipse will reach the Mexican Pacific coast at 11:07 a.m. PT (2:07 p.m. ET), and then traverse the US in a northeasterly direction from Texas to Maine, and on into easternmost Canada. If you want a good look at it, but don’t live in the path of totality, you shouldn’t wait much longer to book accommodation and travel to a spot on the path.

Or how about booking a seat in the sky? Delta Airlines made headlines for offering a flight that allows you to see the entire path of totality. Its first eclipse flight, from Austin, Texas, to Detroit sold out quickly. But as of Monday, Delta has added a second flight from Dallas to Detroit, which also covers the path of totality. The airline also has five flights that will offer prime eclipse viewing.

Not everyone can get on one of those elusive eclipse-viewing flights. Here’s a look at other options to nab a chance to see this rare sight and what to know about it.

Total solar eclipse path

The eclipse will cross over the Pacific coast of Mexico and head northeast over mainland Mexico. The eclipse will then make its way over San Antonio at approximately 2:30 p.m. ET on April 8 and move through Texas, over the southeastern part of Oklahoma and northern Arkansas by 2:50 p.m. ET.

By 3 p.m. ET, the eclipse will be over southern Illinois, and just 5 minutes later, will be traveling over Indianapolis. Folks in northwestern Ohio will be treated to the eclipse by 3:15 p.m. ET, and it will then travel over Lake Erie and Buffalo, New York, by 3:20 p.m. ET. Over the next 10 minutes, the eclipse will be seen over northern New York state, then over Vermont. By 3:35 p.m. ET, the eclipse will work its way into Canada and off the Eastern coast of North America.

Best places to watch the Great American Eclipse

When evaluating the best places to watch this year’s total eclipse, you’ll first want to determine where you’ll have the best angle to see the totality. The farther off-angle you are — in other words, the farther north or south of the eclipse’s path — the less of an impact you can expect.

Therefore, if you want to have the best chance of experiencing the eclipse, you’ll want to be in its path. As of this writing, most of the cities in the eclipse’s path have some hotel availability, but recent reports have suggested that rooms are booking up. And as more rooms are booked, prices are going up.

So if you want to be in the eclipse’s path, and need a hotel to do it, move fast. And Delta’s eclipse-viewing flight from Dallas to Detroit has just four seats left at the time of publication.

Eclipse eye safety and photography

As with any solar eclipse, it’s critical you keep eye safety in mind.

During the eclipse, and especially during the periods before and after totality, don’t look directly at the sun without special eye protection. Also, be sure not to look at the sun through a camera (including the camera on your phone), binoculars, a telescope or any other viewing device. This could cause serious eye injury. Sunglasses aren’t enough to protect your eyes from damage.

If you want to view the eclipse, you’ll instead need solar viewing glasses that comply with the ISO 12312-2 safety standard. Anything that doesn’t meet that standard or greater won’t be dark enough to protect your eyes. Want to get them for free? If you’ve got a Warby Parker eyeglasses store nearby, the company is giving away free, ISO-certified solar eclipse glasses at all of its stores from April 1 until the eclipse, while supplies last.

If you don’t have eclipse viewing glasses handy, you can instead use indirect methods for viewing the eclipse, like a pinhole projector.

In the event you want to take pictures of the eclipse, attach a certified solar filter to your camera. Doing so will protect your eyes and allow you to take photos while you view the eclipse through your lens.

There’s also a new app to help you both protect your eyes and take better photos of the eclipse on your phone. Solar Snap, designed by a former Hubble Space Telescope astronomer, comes with a Solar Snap camera filter that attaches to the back of an iPhone or Android phone, along with solar eclipse glasses for protecting your eyesight during the event. After you attach the filter to your phone, you can use the free Solar Snap Eclipse app to zoom in on the eclipse, adjust exposure and other camera settings, and ultimately take better shots of the eclipse.

2024 eclipse compared to 2017

The last total solar eclipse occurred in 2017, and many Americans had a great view. Although there are plenty of similarities between the 2017 total solar eclipse and the one coming April 8, there are a handful of differences. Mainly, the 2024 eclipse is going to cover more land and last longer.

The 2017 eclipse started over the northwest US and moved southeast. Additionally, that eclipse’s path was up to 71 miles wide, compared with a maximum width of 122 miles for this year’s eclipse. Perhaps most importantly, the moon completely covered the sun for just 2 minutes, 40 seconds in 2017. This year, maximum totality will last for nearly four-and-a-half minutes.
