In practice what we find is that by our testing methodologies the MacBook falls about an hour short, clocking in at 8 hours and 5 minutes.

Our light test is light web browsing, and our heavy test increases the number of pages loaded, adds a 1 MB/s file download, and has a movie playing. Meanwhile to test battery life, we have two workloads. This happens to be identical to what the 11” MacBook Air is rated for, and in practice would be very close to what the Haswell-based 11” Airs hit as well. Officially the MacBook should be able to hit 9 hours of runtime on a light web workload, and 10 hours with video playback. The end result is that relative to the 11” MacBook Air Apple has virtually the same battery capacity to drive a less power-hungry CPU and logic board paired with a more power-hungry display. Using terraced batteries has allowed Apple to maximize the amount of volume the MacBook’s batteries occupy, however at 39.7Wh this only gets them up to roughly where the 11” MBA (38Wh) already sat. Apple needs only to pay this cost once, but it’s an expensive cost.Īll the while Apple also has to deal with the battery capacity limits of such a small chassis. As we’ve seen in other Apple products in the past, going Retina incurs a significant power cost, as the high DPI displays require a much stronger, much more power hungry backlight to light up the display. On the other hand in constructing the MacBook Apple has ditched the MacBook Air’s standard DPI TN panels for high DPI Retina IPS panels. For on the one hand, the CPU at the heart of this laptop is Core M, a very low power CPU specifically designed for thin & light devices, which on its own doesn’t draw all that much power. Removing the speakers requires also removing several other components including the logic board.Last but certainly not least in our look at the MacBook is a look at its battery life and WiFi performance.Īlong with the technical considerations that have gone into making the MacBook as small as it is, I would consider the subject of battery life to be the second most interesting aspect of the MacBook’s design. Therefore, this guide instructs you to remove the speakers before proceeding to the battery. Note: The solvent used to dissolve the battery adhesive can damage your speakers if it comes in contact with the plastic speaker enclosures. If your battery is swollen, take extra precautions.
A charged lithium-ion battery can create a dangerous and uncontrollable fire if accidentally punctured.
To minimize risk of damage, turn on your MacBook and allow the battery to fully discharge before starting this procedure. Do not smoke or work near an open flame during this procedure. Perform this procedure in a well-ventilated area. IFixit adhesive remover is highly flammable.

The adhesive remover in your kit will dissolve the adhesive securing the battery, allowing you to remove it with ease.Īpple issued a battery recall for this model in June of 2019-so before replacing your battery, you can check to see if you are eligible to receive a replacement for free from Apple. Use this guide to safely remove the glued-in battery from your MacBook Pro with the help of an iFixit battery replacement kit.
