The MacBook Air is one of Apple's most popular products, and indeed its most popular Mac. The most recent iteration brings with it an updated keyboard and new processors while retaining features like dual Thunderbolt 3 ports, a Retina display, and SSD storage.
It also has a theoretical battery life of 11-12 hours, though yours is always going to vary depending on use. Apple's estimates are always based on light web usage with the screen brightness turned down, so if you like a bright screen, brightly-lit keyboard, and are downloading gigs and gigs of data, be prepared for notably less than the advertised battery life.
1 day ago however just wondering because the iPhone will have a non genuine battery is that going to cause any problems with the iPhone meaning will it be safe to use the iPhone with a non genuine battery. Is an app available to check to ensure the battery has been installed correctly and should be working the way it’s meant to work. Nov 18, 2019 1. CoconutBattery (macOS Only) CoconutBattery is an extremely tiny applet for the Mac that provides a host of details in regards to the battery condition of your iPad.
Still, if you think you're experiencing an abnormal battery drain on your new MacBook Air, try these tips to fix any issues that you might run into.
Allow setup to finish
If you're setting up a new Mac, or restoring your current one, your computer will be going through its initial setup process for a little while after you've gotten everything configured. This includes things like Spotlight indexing, which can drain your battery significantly faster than normal.
During this process, it's wise to plug your MacBook into power. Once complete, you can unplug your MacBook Air and use it as normal, and the battery should perform perfectly.
Step away
Aside from any excess battery drain during setup, you're likely to expend a lot of power in your initial days with your new machine because you'll be using it more. After all, it's brand new, and you want to use your shiny new toy.
But that burst of additional use has its tradeoffs. The initial days and weeks of owning a new MacBook will likely see higher than normal use. Your display will be on longer, your Wi-Fi use will be higher, and you might even be taxing your processor more than normal.
If you think your battery is only, for instance, lasting half as long, might you be using your computer twice as much as you normally would?
The key here is the walk away. Make a note of how much battery you have left when you stop using your computer, then just put it to sleep and step back. If you see only small changes in battery level when you return, your battery is probably good to go, and you've just been taxing it with a bit of overuse.
If, however, your MacBook Air's battery drained significantly while not in use and asleep, you'll need to do something else.
Run down the battery
Perhaps the simplest (if theoretically most time-consuming) thing you can do in an attempt to correct battery problems is first run down the battery. Use your MacBook Air until it shuts down because the battery level is so low. After this happens, plug your MacBook Air into power.
Then, just walk away. Wait for your MacBook Air to fully charge before taking it off of power again. After you do take it off power and start using it again, see if you're still seeing the same battery drain as you were before. If so, it's time to try some of these other tips.
Restart your Mac
Restarting is a simple way to try and kill any battery issues you might be having. Often when you're having battery problems, it can be something like a rogue process, a bad app, or something else of that nature, and restarting is a way to essentially nuke everything that's currently running on your Mac.
Here's how to restart your MacBook Air:
- Click on the Apple menu button in the upper left corner of your screen.
Click Restart....

- Click the Restart button on the pop-up menu to confirm.
Once your MacBook Air has been rebooted, try the previous methods to see if the battery drain issues have been solved.
Run all of the updates
While both macOS and most apps these days are often optimized better for modern Macs, especially laptops, problems do crop up. It could be a bug in the latest version of macOS or the new update to a favorite app. In any case, you want to make sure that both your operating system and third-party software are all updated to smooth over any bugs.
Good developers are often quick with a fix if a problem is spotted in their app, so you're going to want to make sure that software is updated to its latest version.
- Launch the App Store from the Dock or Finder.
Click Updates in the side panel menu.

Click Update next to each app you'd like to update, or click Update All.

- Enter your Apple ID password if prompted.
For non-Mac App Store apps, you can typically go to the Menubar and find Check for Updates in the app menu or help menu section.
You'll also want to keep macOS up-to-date, which you can do by following this guide.
Check power usage of apps
For the past several versions now, Apple has offered the ability to 'battery shame' power-hungry application. Clicking the battery icon in the Menu bar will show you what applications are using a significant amount of energy.
There are a couple of great things about this. First, it doesn't show you which applications are using the most energy, just those that are using significant energy. That way, apps that may happen to be technically using the most energy at a given time aren't unnecessarily shamed. Second, clicking on an offending app will open Activity Monitor, which lets you see every resource that the app is using.
There's often good reason for an app to be consuming a significant amount of energy. But a lot of the time, it comes down to factors such as poor optimization for the hardware. This can happen when you, for instance, when developers build their apps in tools like Electron, which are cross-platform, but not well-optimized. That's why you want to…
Run native apps
Where you can, you should run native applications, rather than cross-platform or web apps. Running Safari, which is Apple's own browser that they code specifically for macOS, is better for your battery than Chrome. Chrome may be incredibly popular, but that comes at the cost of being less able to optimize for a specific platform. Chrome is also RAM-hungry, which, yes, uses more power.
Other apps, like Slack, which is built on the cross-platform Electron framework, are just wrappers around web apps. Adobe's apps like Lightroom and Photoshop are all-native, but they're also cross-platform and tend to use more energy than Mac-first or Mac-only apps like Pixelmator and Acorn.
Stretch your battery life
If you're battery's working fine, but you're stuck without power for the next several hours, are are some things you can do to eek out as much power as you can until you can connect to a charger.
- Turn down the screen brightness.
- Turn off Wi-Fi if you don't need to be online.
- Use headphones instead of the speakers if you have to listen to audio or music.
- In the Energy Saver section of System preferences, turn on Automatic Graphics Switching, Put hard disks to sleep when possible, and Wake for Wi-Fi network access options.
Also, be sure to quit apps that you're not using so that they don't take up excess power.
Contact Apple
Sometimes there's just going to be an issue that you can't fix on your own. You'll need to contact Apple or, if possible, book a Genius Bar appointment in order to see an expert in person. If you want, you can also call 1-800-MY-APPLE to start the process for a mail-in repair.

if only you knew the power of the dark side...Apple doubles trade-in value of select Android devices for a limited time
Apple has quietly upped the trade-in price of several Android smartphones for a limited time, doubling the value of some handsets.
The iPhone received a native Battery Health tool a while back. Although it doesn't generate as much useful information as I would like, it still gives me a rough idea of the overall condition of my iPhone's battery. But sadly, Apple has omitted this vital tool from the iPad. And even with the release of iPadOS, that has not changed.
That's why I seeked a third-party desktop tool to check the battery health on my iPad that's been with me for over four years. I had to be sure that there were no battery-related issues around the corner.
Thankfully, I found not one, but three great tools that could help me determine the condition of the battery on my iPad easily. They work on both macOS and Windows. So you won’t be left in the cold, no matter your preferred desktop platform.

4 Useful Tips for Getting the Most Juice Out of Your MacBook’s Battery Life
Read More1. coconutBattery (macOS Only)
CoconutBattery is an extremely tiny applet for the Mac that provides a host of details in regards to the battery condition of your iPad. After downloading and installing the program, open it, switch to the iOS Device tab, and you will see all pertinent details in regards to your iPad’s battery.
Download coconutBatteryEssential details include Full Charge Capacity and Design Capacity. The former details the current charge capacity of your iPad, while the latter displays its original capacity — the greater the discrepancy between the two, the worse off the battery is.
Additionally, you can find a percentage value underneath Design Capacity, which is derived by dividing the Full Charge Capacity by the Design Capacity. As a general rule, you only have to worry about getting a replacement battery — or switching to a new iPad — once this value falls below 80 percent. Mine stands at 92.5 percent, so I don’t have anything to worry about yet.
Another vital piece of information is the value next to Cycle Count. This reading gives off the total number of charge cycles that your iPad has undergone ever since you first started to charge it. Apple puts the maximum charge cycles for an iPad at a thousand, so at 477 charge cycles, I’m still in the clear.
The other details listed within the app are largely irrelevant, but the reading next to Temperature can come in handy if you have any issues with overheating.

2. iMazing (macOS and Windows)
I love coconutBattery due to its simplistic yet focused nature. But if you have issues installing it on your Mac, or if you only have a Windows-based desktop at hand, then iMazing is a fantastic alternative.
Download iMazingiMazing is a program that resembles iTunes, where you can back up your iPad as well as perform a host of other maintenance tasks. And it also lets you determine the battery health of your iPad. Thankfully, the free version is more than sufficient for the job at hand.
After installing iMazing on macOS or Windows, open it and click the Battery icon to the lower-right corner of the iMazing window.
Then, you will be greeted with a pop-up window that includes all the details that you want — Design Max Charge, Effective Max Charge (same as Full Charge Capacity in coconutBattery), Charge Cycles, Temperature, etc.
After that, iMazing will even throw in a 'Your battery health is good' notification if there are no immediate concerns with the Effective Max Charge and Charge Cycles readings.
3. 3uTools (Windows)
3uTools is another application that you can use to check the health of your iPad battery easily using a Windows desktop. However, I'm not the biggest fan of 3uTools since it runs rather sluggishly — I recommend that you only use it if iMazing fails to work properly on your PC.
Download 3uToolsAfter installing 3uTools, open the application, connect your iPad to your PC, and then click Details next to Battery Life.
You will then see a nifty pop-up box with the relevant details underneath the Battery section — Charge Times, Actual Capacity, Design Capacity, Temperature, etc.
During my tests, 3uTools battery cycle count (which was 477 times) did fall in line with the readings that I got on coconutBattery and iMazing. However, it presented a higher actual charge capacity at 7062mAh (as opposed to 6972mAh and 6740mAh on the other apps).
While these readings are subject to change for each app, 3uTools did go off the mark by quite a bit here and is another reason for you to use it only if iMazing fails to work on your PC.
