It takes about 1.7 hours to fully charge a battery depleted Apple 13" MacBook Air (2020) using at least a 50W USB PD charger vs 2.8 hours when using the in-box 30W charger. Given these power consumption levels, we can clearly see the advantages of using at least a 50W USB PD power source vs the Apple 30W USB-C Power Adapter when using power hungry applications or needing to quickly charge your battery.
APPLE MACBOOK CHARGER 1172 MAC
When connected to a 60W USB PD charging source, we can see that the Apple 13" MacBook Air (2020) actually pulls a maximum of 47.5W for much of the 0 to 70% battery charging period. Initially the Mac max temperature on its surface gets up to a hot 50 deg C but settles to 40 deg C later.Īfter 70% charge, the Apple 13" MacBook Air (2020) starts to reduce its power to help improve battery life, and it takes about 104 minutes to fully charge the Mac.Īfter the Apple 13" MacBook Air (2020) is fully charged, the Mac uses just 14-22W while the Mac display is on without any significant power hungry applications consuming power. When Time Machine is used for backup, the Mac power consumption increases to 17-33W. Now let's look at how the Apple 13" MacBook Air (2020) can actually take advantage of higher than 30W by using the GRL-C2 USB PD Tester to emulate a 60W USB PD charger, This extended post "100%" battery charging could explain why the Apple 13" MacBook Air (2020) reports staying at 100% battery for about 13 minutes before the battery appears to start discharging. Interestingly, we see that the Mac still appears to be charging for another 25 minutes after the Mac has reported 100% battery. During this time, the Apple 30W USB-C Power Adapter gets quite hot, reaching and uncomfortable 63 degrees C. Using the GRL-C2 USB PD Tester and GRL-PSP Power Analyzer software from Granite River Labs, we can see it takes about 2.8 hours for the Apple 13" MacBook Air (2020) to report 100% battery, after starting to charge at close to 0% battery. This Mac ships with a small Apple 30W USB-C Power Adapter. However, if you are running power hungry applications, 30W seems a bit low given that a lot of tablets are already in this range and even smartphones have started charging above 30W. The Apple 13" MacBook Air (2020) is a great option if you need both affordability and portability ( or just want to avoid the Touch Bar). plug it in as long as you can (especially at home) since cycle count on the battery are the "miles that wear out the tires (battery)"Īnd best "tip" is if its near a socket.
Anything can be abused even if it doesnt need conditioning.īut really all you would keep in mind is -"consider 20% is the same as 0% and recharge it"Īnd best "tip" is if its near a socket. does NOT mean they dont have an ideal use / recharge environment.
Just because LiPo batteries dont need conditioning in general. *Cycle count / use/ lifespan is one thing that cant be countered. make sure it has at least a 50% or so charge. *Also, if youre going to store your macbook away for a few weeks or more. Same way you dont take a new car out and speed and rev the engine hard first 100 or so miles. First ten cycles or so, don't discharge down past 40% of the battery's capacity. The only quantified abuse seen to LiPo cells is instances when often the cells are repeatedly drained very low.Ĭontrary to what some might say, LIPo batteries have an "ideal" break in period.
**Also new evidence suggests that sudden loss of power can adversely affect data on a SSD (solid state drive).again, dont let it ever shut down from total power loss
Never let your Macbook die from power, you can corrupt files that way, and the batteries do not like it. then recharge them for longer overall life. key word being "often"Ī lot of battery experts call the use of LiPo cells the "80% Rule". LiPo batteries do NOT like to be dropped down to 15% or so often. LiPo (lithium polymer, same as in your macbook) batteries do not need conditioning. *Contrary to some myths out there, there is protection circuitry in your macbook and therefore you cannot 'overcharge'it when plugged in and already fully charged Keep it plugged in when near a socket so you keep the charging cycles DOWN on your LiPo (lithium polymer) cells / battery.
