Introduced with iOS 9, Low Power Mode is an easy way to extend the battery life of your iPhone when it starts to get low. Your iPhone lets you know when your battery level goes down to 20%, and again at 10%, and lets you turn on Low Power Mode with one tap. Or you can enable it by going to Settings > Battery. Low Power Mode reduces display brightness, optimizes device performance, and minimizes system animations. Apps including Mail will not download content in the background, and features like AirDrop, iCloud sync, and Continuity will be disabled. You can still use key functions like making and receiving phone calls, email, and messages, accessing the Internet, and more. And when your phone charges up again, Low Power Mode automatically switches off.

Low Power Mode prolongs battery life by turning off always-on display, limiting the cellular and Wi-Fi connections of your Apple Watch, and disabling background sensor readings including heart rate measurements, high and low heart rate notifications, irregular rhythm notifications, and blood oxygen measurements.
When not connected to your iPhone, your Apple Watch will attempt to retrieve notifications approximately once an hour. When your Apple Watch battery reaches 80% charge Low Power Mode automatically switches off.
Brightness. Dim the screen to the lowest comfortable level to achieve maximum battery life. For instance, when watching a video on an airplane, you may not need full brightness if the cabin lights are off.
The Apple MacBook Air 11-inch ($1,099 as tested) is an ultraportable laptop in the purest sense of the term. It is very compact, delivers all-day battery life, and is very easy to drop into a travel bag, whether your commute is an hour or eight. The MacBook Air 11-inch($295.00 at eBay)(Opens in a new window) has few rivals among the Windows 8-equipped ultrabooks. Its big brother, the Editors'-Choice-winning Apple MacBook Air 13-Inch (2014), is still a better bet because of its larger screen, increased battery life, and better ergonomics, for about the same price). But if you're willing to give up a few common features in return for ultimate portability, the MacBook Air 11-inch is a great choice as your everyday traveling companion.
Performance The updated Intel Core i5-4260U processor is the primary upgrade over the previous iteration of the 11-inch MacBook Air, and it helps boost performance without sapping battery life. The processor is only 100MHz faster, but the system gains speed on multimedia tests like Handbrake (1 minute 18 seconds) and Photoshop CS6 (5:08). These scores are quick for the category, beating out the Acer Aspire S7-191-6640( at Amazon)(Opens in a new window) (1:29 on Handbrake; 6:32 on CS6), the Dell XPS 11 (2:14 on Handbrake; 6:50 on CS6), the Sony VAIO Flip 11 (2:02 on Handbrake; 13:18 on CS6) and the Sony VAIO Tap 11($789.99 at Amazon)(Opens in a new window) (2:30 on Handbrake; 6:57 on CS6). About the only similar system in price and portability that beats it is the Microsoft Surface Pro 2 (1:13 on Handbrake; 4:25 on CS6).
Battery life is where the MacBook Air really shines, scoring 10 hours 54 minutes on our battery rundown test. The best the competition could manage was 7:19 on the Microsoft Surface Pro 2 and 6:58 on the Acer S7-191-6640. The system's battery score is 12 minutes better than last year's iteration. This means that you could theoretically fly cross-country both ways on the same charge, as long as you keep the laptop turned off and stowed away during the takeoffs and landings. The larger Apple MacBook Air 13-inch is our current battery champ in the category, lasting 15:51.
The Apple MacBook Air 11-inch (2014) gives the road warrior plenty of pluses, such as ultimate portability, photo and video performance, and all-day battery life. These make up for the system's shortcomings (limited ports, a few comfort issues, and a lower-resolution screen than its Windows-based counterparts). The only ultraportable that rivals it is its big brother, the MacBook Air 13-inch (2014). That system offers a larger screen, much longer battery life, and better ergonomics, and it remains our Editors' Choice for ultraportable laptops. If you constantly work untethered in varied locations or have a well-worn platinum airline frequent flier card in your wallet, however, the 11-inch MacBook Air makes a great travel companion.
Batteries have a limited amount of charge cycles before their performance is expected to diminish. Once the cycle count is reached, a replacement battery is recommended to maintain performance. You can use your battery after it reaches its maximum cycle count, but you might notice a reduction in your battery life. In macOS Catalina 10.5.5 or later, you can turn on optimized battery charging to help reduce battery aging. This lets your Mac learn your charging routine and wait to charge past 80% until you need to use it.
Knowing how many charge cycles your battery has and how many are left can help you determine when a battery replacement is required. Your battery is designed to retain up to 80% of its original charge capacity at its maximum cycle count. For best performance, replace your battery when you reach its maximum cycle count.
MacBook Air features a new, strikingly thin design in four beautiful finishes, larger 13.6-inch Liquid Retina display, 1080p HD camera, MagSafe charging, and moreM2 also comes to the 13-inch MacBook Pro with 24GB of fast unified memory, ProRes acceleration, and up to 20 hours of battery life
The 2015 Apple MacBook Air 11-inch ($899 as tested) is all about ultraportability. This year's model gets a modest CPU update from last year's iteration, but while its Editors' Choice-winning stablemate, the 2015 Apple MacBook Air 13-inch, is aimed at pleasing a wider range of users, the 11-inch ultraportable makes a few tradeoffs to become even thinner and lighter. Even so, its Intel Core i5 processor means that it breezes through tasks that would slow an Intel-Core-M-equipped system, and that's on top of its 11.5 hours of battery life. The MacBook Air 11-inch is a wonderful commuter laptop, and it should be on your short list if you're constantly on the move.
With its 38-watt battery, the MacBook Air 11-inch lasted 11 hours 33 minutes on our rundown test. That's far less than the astounding 17:36 of the 13-inch MacBook Air and its larger 54-watt battery, but a much longer runtime than the Acer Aspire S7-393-7451 (9:57). The Air should last throughout a cross-country flight, and have juice left for another work session afterward.
Since the 11-inch MacBook Air packs the same memory, processor, and storage as its 13-inch big brother, it's no surprise that the two returned almost identical performance scores save for battery life. If you can handle the larger size and the $100 premium, go for the 13-inch, the extra juice is worth it.
ConclusionThe latest 11-inch Apple MacBook Air might be one of the smallest ultraportable laptops on the market, but its powerful Intel Core i5 processor and long-lasting battery life help it stay ahead of its Core-M-equipped rivals. It also offers better connectivity options than the Apple MacBook. Consider buying one if you're replacing a three-year-old or older MacBook Air or Windows ultraportable, but you can probably skip it if you have last year's model. The newest Apple MacBook Air 13-inch remains our Editors' Choice for midrange ultraportable laptops with its larger screen and astounding battery life for only $100 more.
Battery degradation is an inevitable part of your laptop's lifespan, extend it with this new replacement battery compatible with Mid 2011 to Early 2015 model 11" MacBook Airs. Factory-installed MacBook Air batteries are rated to last 1,000 cycles. If your laptop won't turn on, turns off suddenly, has a "service battery" warning, or simply won't hold a charge, this replacement battery may be what you need to fix it. Our aftermarket replacement batteries lead the industry in quality and reliability, so you know you're getting the best money can buy.
A small percentage of users have experienced issues with aftermarket (non-Apple) batteries failing to be recognized properly in devices running Mac OS X El Capitan (10.11.x) or Sierra (10.12.x). If your system does not operate properly with our replacement battery, it can be returned for a full refund.
For optimal performance, calibrate your newly installed battery: Charge it to 100% and keep charging it for at least 2 more hours. Then use your device until it shuts off due to low battery. Finally, charge it uninterrupted to 100%.
Most MacBook models should offer you all-day battery, at least when new. That actually translates to about 12-13 hours battery life for the 2018 and 2019 MacBook Air models, 10 hours for the 13in MacBook Pro (2018/2019), 10 hours for the 15in MacBook Pro (2018/2019), and 11 hours for the 16in MacBook Pro (2019).
It should be obvious that Normal indicates a healthy battery. Perhaps surprisingly, Replace Soon is a mere warning rather than a demand and your MacBook should still function correctly on battery power, albeit with noticeably shorter battery life than when it was new.
Another figure worth noting within CoconutBattery is the Cycles Count figure, which is also known as the charge cycles figure. This measures how many times 100% of the battery charge has been used-up. This is important because during each charge cycle the battery loses a small fraction of its ability to hold charge, which is what causes the capacity to drop over time.
Storing a MacBook fully charged for a prolonged length of time without use can permanently reduce the overall charging capacity. Storing a MacBook fully discharged can lead to what Apple calls a deep discharge state, which might make it impossible to charge the battery in future. To avoid either situation try to store your MacBook 50% charged, and shutdown before storing it, rather than letting it go into sleep mode. 2ff7e9595c
