Product Information

The single-core test, on the other hand, measures the CPU performance when just one of its cores is in use. Moreover, a high score on these tests signifies good processor performance. Compared with the 1,920-by-1,080 or higher resolution that's common for midrange Windows laptops, the MacBook Air's 1,440-by-900 resolution seems relatively deficient, at least on paper. However, the screen appears clear and bright in real-world use. It should be sufficient for day-to-day tasks, like writing office documents and Web browsing. If you need a higher-resolution Mac laptop, you'll have to go for the pricier Apple MacBook and its 2,304-by-1,400-resolution screen or the latest Apple MacBook Pro 13-inch with its 2,560-by-1,600-resolution display. There is currently no option to add a high-resolution Retina Display to the MacBook Air; it would increase the system's cost and weight and decrease battery life. If your battery isn't charging, make sure you're using the correct power adaptor for your Mac. If the power adaptor isn't rated for at least the wattage that your Mac requires, it may not charge your Mac reliably. If you're using the correct power adaptor, make sure the power adaptor isn't at fault: Hence, I will rate the MacBook Air 2015 a nine out of ten in this CPU review section. MacBook Air 2015 Memory (RAM) Performance Review Independent tests use a variety of different methods and can provide a well rounded evaluation of battery life in "real world" use as a result.

This is because SSDs are one of the fastest, if not the fastest storage drives available. Also, thanks to its SSD, the MacBook Air 2015 should have a fast read and write speed. To further prove this laptop’s performance with this CPU, let us consider its Cinebench R15 test result. The Cinebench R15 is a benchmark test that assesses the processor performance of a computer by testing its cores. Therefore, the MacBook Air 2015 deserves a rating of nine out of ten in this storage review section. MacBook Air 2015 Graphics Card Performance ReviewFor many years now, Apple's battery life estimates have been reasonable, but third-party test results still can be useful. It also is worth noting that all MacBook Air models have built-in lithium polymer batteries that are not intended to be removed, or even replaced by an end user, although it is possible for those with some technical capability to do so.

To prove that, we will now highlight the laptop’s result on the CystalDiskMark test. Briefly, CrystalDiskMark is a cross-platform app-based test that measures the read and writes speed of a computer’s storage drive. Whereas, the right side of the laptop houses another USB 3.0 port, a Thunderbolt 2 port, and an SDXC card slot. In summary, the MacBook Air 2015 features an integrated graphics card that offers adequate performance for basic graphics tasks. Also, with the graphics card, the laptop is able to play a few outdated games. Besides, this laptop beats one of its competitors on a graphics benchmark test. Hence, I will rate the MacBook Air 2015 an eight out of ten in this graphics review section. MacBook Air 2015 Battery Life and Performance Review

Please note that all MacBook Air models mentioned in this Q&A have been discontinued. However, this Q&A is up-to-date and remains quite useful to anyone buying or selling one of these Mac notebooks on the used market. For your safety, drain your MacBook's battery before you begin this procedure. A charged lithium-ion battery can create a dangerous and uncontrollable fire if accidentally punctured. In conclusion, the MacBook Air 2015 offers a fast SSD and an SDXC card slot for storage expansion. Besides, the laptop outperformed most of its competitors on a storage benchmark test.
