Apple’s macOS is perhaps one of the most impressive and productive operating systems around. With the new macOS 11.2 Big Sur update Apple is. The apple company have incorporated high-end technology into their gadgets which enhance their battery life. Research has proven that Macbooks can last up to twelve hours when the battery capacity.
Start up from macOS Recovery
Determine whether you're using a Mac with Apple silicon, then follow the appropriate steps:
Apple silicon
Turn on your Mac and continue to press and hold the power button until you see the startup options window. Click the gear icon labeled Options, then click Continue.
Intel processor
Make sure that your Mac has a connection to the internet. Then turn on your Mac and immediately press and hold Command (⌘)-R until you see an Apple logo or other image.
If you're asked to select a user you know the password for, select the user, click Next, then enter their administrator password.
Reinstall macOS
Select Reinstall macOS from the utilities window in macOS Recovery, then click Continue and follow the onscreen instructions.
Follow these guidelines during installation:
- If the installer asks to unlock your disk, enter the password you use to log in to your Mac.
- If the installer doesn't see your disk, or it says that it can't install on your computer or volume, you might need to erase your disk first.
- If the installer offers you the choice between installing on Macintosh HD or Macintosh HD - Data, choose Macintosh HD.
- Allow installation to complete without putting your Mac to sleep or closing its lid. Your Mac might restart and show a progress bar several times, and the screen might be empty for minutes at a time.
After installation is complete, your Mac might restart to a setup assistant. If you're selling, trading in, or giving away your Mac, press Command-Q to quit the assistant without completing setup. Then click Shut Down. When the new owner starts up the Mac, they can use their own information to complete setup.
Other macOS installation options
When you install macOS from Recovery, you get the current version of the most recently installed macOS, with some exceptions:
- On an Intel-based Mac: If you use Shift-Option-Command-R during startup, you're offered the macOS that came with your Mac, or the closest version still available. If you use Option-Command-R during startup, in most cases you're offered the latest macOS that is compatible with your Mac. Otherwise you're offered the macOS that came with your Mac, or the closest version still available.
- If the Mac logic board was just replaced, you may be offered only the latest macOS that is compatible with your Mac. If you just erased your entire startup disk, you may be offered only the macOS that came with your Mac, or the closest version still available.
You can also use these methods to install macOS, if the macOS is compatible with your Mac:

- Use the App Store to download and install the latest macOS.
- Use the App Store or a web browser to download and install an earlier macOS.
- Use a USB flash drive or other secondary volume to create a bootable installer.
For almost as long as there have been Windows laptops, there has always been a giant squid in the room: Why is Windows’ battery life so damn pitiful? For years I thought it was simply a matter of display and processor technology outstripping battery tech, but when Apple entered the scene with the MacBook Pro and Air, and iPad, it became very clear that Windows itself was to blame. The battery life discrepancy between Windows and other operating systems has never been clearer than with the Surface Pro 2 and the 2013 MacBook Air — both have very similar specs (Haswell Core i5 CPU/GPU, battery size), and yet Apple’s laptop has almost twice the battery life of Microsoft’s tablet.
While it’s clear that Windows laptops with good battery life do exist, that’s really beyond the point — and usually just a result of large batteries powering relatively underpowered hardware. What we’ve noticed over years of handling a variety of Windows, Mac, iOS, and Android devices — and formalized in an excellent discussion by Jeff Atwood — is that Windows seems to magically decimate the battery life of laptops and tablets. You can have two devices with almost exactly the same specs (iPad vs. Surface RT, MacBook Air vs. an ultrabook), and somehow the Windows machine will have between 25 and 50% less battery life.
If you want to prove this yourself, try installing Windows 8 on 2013 MacBook Air. The 13-inch model (OS X 10.8) usually manages around 14 hours of battery life with light, WiFi web browsing usage — with Windows, that figure drops to around eight hours. The depressing thing is that the difference between Windows and OS X seems to be growing, too: The 2009 15-inch MacBook Pro managed around eight hours with OS X 10.5.7, and six hours with Windows Vista x64 SP1.
What’s causing Windows’ poor battery life? That’s a good question that no one seems to know the answer to. Atwood even asked Anand Shimpi of Anandtech fame, but he too drew a blank. The most sensible argument is that Apple designs its hardware and software to work synergistically — the software is perfectly tailored to make the most of the hardware, and thus it uses less energy to get things done. Microsoft, on the other hand, has to write software that works equally well across a massive range of hardware, and thus can’t include the low-level optimizations that would result in lower idle and load power usage for every CPU, GPU, and wireless chip/modem under the sun.
This argument falls down when you look at the Surface Pro 2 and 11-inch 2013 MacBook Air, though. Both devices were designed in-house, so Microsoft can’t claim that Windows isn’t optimized for the hardware. Both have Intel’s Core i5-4200 (Haswell) CPU, 4GB of RAM, and NAND flash storage. The MBA does have a lower-res display (1366×768 vs. 1920×1080 on the Surface Pro 2), but it also has a 10% smaller battery (38 watt-hours for the MBA, vs. 42 watt-hours for the Pro 2). The only other difference is that the MBA’s i5-4200U is clocked at 1.3GHz, vs. 1.6GHz for the Surface Pro 2 (but they both have the same Turbo Boost speed of 2.6GHz). Using Anandtech’s WiFi web browsing battery life benchmark, the Surface Pro 2 manages 6.68 hours — the 11-inch 2013 MacBook Air, on the other hand, clocks in at 11.1 hours. That’s Apple’s OS X delivering almost twice the battery life of Microsoft’s Windows 8, on almost exactly the same hardware. Go figure.

Even though the Surface Pro 2 was made in-house by Microsoft, it still has far less battery life than the 2013 MacBook Air, which has very similar specs.
Even though both devices were made in-house, the sad answer to this quandary — why Windows has worse battery life than OS X, iOS, or Android — is probably that Microsoft simply hasn’t put as much focus on idle and low-utilization power consumption as Apple and Google. Yes, the Surface Pro 2 is a first-party device where Microsoft controls both the hardware and software — but that doesn’t mean that Microsoft magically has the battery life expertise that Apple has been honing for almost a decade. We can’t say for certain, but given the huge disparity in battery life, there is either a massive flaw in the Windows kernel and low-level libraries resulting in massive power wastage (unlikely), or it’s simply a case of lots of little inefficiencies across the code base that add up (more likely).
Either way, though, the end result is that the awesome power consumption gains being made by Intel’s latest chips will amplify Windows’ lackluster battery life. As you can see in the chart above, the Surface Pro 2 has 40% better battery life than the original Pro, and that’s almost entirely thanks to the new Haswell chip. Going from 4.7 to 6.7 hours is nice, of course, but going from 10 to 14 hours looks, sounds, and is better. For fans of Windows, there’s no short-term solution here: Microsoft will need to do a lot of work to reduce its idle power consumption to OS X or iOS levels. If you’re looking for a good laptop for working from the coffee shop, the MacBook Air or tomorrow’s Haswell-powered MacBook Pros are likely to be your best bet for the foreseeable future.
