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.

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.

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.

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.

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.

Google races to put Gemini at the center of Android before Apple’s AI reboot

Google is using its latest Android rollout to position Gemini as the AI layer across phones, Chrome, laptops and cars.

Google is using its latest Android rollout to make Gemini less of a chatbot and more of an operating layer across the phone, browser, car and laptop, just weeks before Apple is expected to show its own Gemini-powered Apple Intelligence reboot at WWDC.
Ahead of its Google I/O developer conference next week, the company previewed a number of Android updates, including AI-powered app automation, a smarter version of Chrome on Android, new tools for creators, a redesigned Android Auto experience, and a sweeping set of new security features.
Alphabet is counting on Gemini to help Google compete directly with OpenAI and Anthropic in the market for artificial intelligence models and services, while also serving as the AI backbone across its expansive portfolio of products, including Android. Meanwhile, Gemini is powering part of Apple’s new AI strategy, giving Google a role in the iPhone maker’s reset even as it races to prove its own version of personal AI on the phone is further along.
Sameer Samat, who oversees Google’s Android ecosystem, told CNBC that Google is rebuilding parts of Android around Gemini Intelligence to help users complete everyday tasks more easily.
“We’re transitioning from an operating system to an intelligence system,” he said.
As part of Tuesday’s announcements. Google said Gemini Intelligence will be able to move across apps, understand what’s on the screen and complete tasks that would normally require a user to jump between multiple services. That means Android is moving beyond the traditional assistant model, where users ask a question and get an answer, and acting more like an agent.
For instance, Google says Gemini can pull relevant information from Gmail, build shopping carts and book reservations. Samat gave the example of asking Gemini to look at the guest list for a barbecue, build a menu, add ingredients to an Instacart list and return for approval before checkout.
A big concern surrounding agentic AI involves software taking action on a user’s behalf without permissions. Samat said Gemini will come back to the user before completing a transaction, adding, “the human is always in the loop.”
Four months after announcing its Gemini deal with Google, Apple is under pressure to show a more capable version of Apple Intelligence, which has been a relative laggard on the market. Apple has long framed privacy, hardware integration and control of the user experience as its advantages.
Google’s Android push is designed to show it can bring AI deeper into the device experience while still giving users control over what Gemini can see, where it can act and when it needs confirmation.
The app automation features will roll out in waves, starting with the latest Samsung Galaxy and Google Pixel phones this summer, before expanding across more Android devices, including watches, cars, glasses and laptops later this year.
The company is also redesigning Android Auto around Gemini, turning the car into another major surface for its assistant. Android Auto is in more than 250 million cars, and Google says the new release includes its biggest maps update in a decade and Gemini-powered help with tasks like ordering dinner while driving.
Alphabet’s AI strategy has been embraced by Wall Street, which has pushed the company’s stock price up more than 140% in the past year, compared to Apple’s roughly 40% gain. Investors now want to see how Gemini can become more central to the products people use every day.

Waymo recalls 3,800 robotaxis after glitch allowed some vehicles to ‘drive into standing water’

Waymo issued a voluntary recall of about 3,800 of its robotaxis to fix software issues that could allow them to drive into flooded roadways.

Waymo is recalling about 3,800 robotaxis in the U.S. to fix software issues that could allow them to “drive onto a flooded roadway,” according to a letter on the National Highway Traffic Safety Administration’s website.
The voluntary recall is for Waymo vehicles that use the company’s fifth and sixth generation automated driving systems (or ADS), the U.S. auto safety regulator said in the letter posted Tuesday.
Waymo autonomous vehicles in Austin, Texas, were seen on camera driving onto a flooded street and stalling, requiring other drivers to navigate around them. It’s the latest example of a safety-related issue for the Alphabet-owned AV unit that’s rapidly bolstering its fleet of vehicles and entering new U.S. markets.
Waymo has drawn criticism for its vehicles failing to yield to school buses in Austin, and for the performance of its vehicles during widespread power outages in San Francisco in December, when robotaxis halted in traffic, causing gridlock.
The company said in a statement on Tuesday that it’s “identified an area of improvement regarding untraversable flooded lanes specific to higher-speed roadways,” and opted to file a “voluntary software recall” with the NHTSA.
“Waymo provides over half a million trips every week in some of the most challenging driving environments across the U.S., and safety is our primary priority,” the company said.
Waymo added that it’s working on “additional software safeguards” and has put “mitigations” in place, limiting where its robotaxis operate during extreme weather, so that they avoid “areas where flash flooding might occur” in periods of intense rain.

Qualcomm tumbles 13% as semiconductor stocks retreat from historic AI-fueled surge

Semiconductor equities reversed sharply after a broad AI-driven advance, with Qualcomm suffering its worst day since 2020 amid inflation concerns and rising oil prices.

Semiconductor stocks fell sharply on Tuesday, reversing course after an extensive rally that had expanded the artificial intelligence investment theme well past Nvidia and driven the industry to unprecedented levels.

Qualcomm plunged 13% and was on track for its steepest single-day decline since 2020. Intel shed 8%, while On Semiconductor and Skyworks Solutions each lost more than 6%. The iShares Semiconductor ETF, which benchmarks the overall sector, fell 5%.

The sell-off came after a key gauge of consumer prices came in above forecasts, and as conflict in Iran pushed crude oil higher—prompting investors to shift away from riskier assets.

The preceding advance had widened the AI opportunity set beyond longtime industry leader Nvidia, which for much of the past several years had largely carried the market to new peaks on its own.

Explosive appetite for central processing units, along with the graphics processing units that power large language models, has sent chipmakers to all-time highs.

Market participants are wagering that the shift from AI model training to autonomous agents will lift demand for additional AI hardware. Among the beneficiaries are memory chip producers, which are raising prices as supply remains tight.

Micron Technology slid 6%, and Sandisk cratered 8%. Sandisk’s stock has surged more than six times over since January.
