preface
As we all know not long ago, the MagSafe charger updated two versions of the firmware, the charging performance is mixed, Apple in the user experience and charging performance between the two indulgent pull, so that users are also confused, anyway follow the update on the right! The MagSafe power supply that also uses MagSafe coils has also been updated, and this time the charging head network has tested the updated performance of this power supply that supports two-way wireless charging.
Product introduction
Apple's original MagSafe power pack has nothing to say, full of fruity flavor, and the front is printed with the appearance of this power bank.
The whole charging treasure has a strong apple flavor, whether it is from the product packaging or the product itself, the skin-friendly material shell, the magnetic side has a flocking cover, with its own Lightning input interface and power indicator.
While the charging treasure is charging the mobile phone, it also supports input, and can charge itself through the Lightning interface of the charging treasure, at which time the charging treasure and the mobile phone are charging.
Apple MagSafe magnetic wireless charging treasure is highly integrated with Apple ecology, and when the charging treasure charges the iPhone 12, it not only has a pop-up WINDOW UI when it is connected, but also can view the power of the charging treasure on the mobile phone. In terms of self-charging, the charging treasure supports PD fast charging, and it is recommended to use a PD charger with 20W and above when charging the charging treasure alone.
Product testing
After reading all this, let's first test the data of the MagSafe power supply.
Charging test
The charging treasure is wirelessly charged for the mobile phone, and the L port of the charger connected to the charging treasure is charged for both, and the measured input power is about 21.44W.
The charging cable is connected to the phone and charges both the MagSafe power supply and the iPhone, with an input power of about 22.8W.
Firmware upgrade
The MagSafe power supply is updated in a similar way to the MagSafe charger, and you can upgrade the firmware by charging your iPhone or connecting to your MacBook.
The firmware version before the upgrade was 2.0.2c.0.
The upgraded firmware version is 2.5.b.0, and there are additional hardware versions below.
Charging compatibility testing
Is there any change to the compatibility after the update? Let's go to the measured part.
The uninformed MagSafe power supply charges the iPhone 12 magnetically, charging the phone with an input power of about 17.3W.
The updated firmware's MagSafe power supply charges the iPhone 12 magnetically, charging the phone with an input power of about 17.25W.
The uninformed MagSafe power supply charges the iPhone 12 magnet while charging the charging treasure, with an input power of about 19.2W.
Updated firmware MagSafe power supply for iPhone 12 magnetic charging at the same time, for the charging treasure charging, input power of about 25.96W, it seems that the update is still changing, the next through the whole process to confirm it.
Full test of charging
The MagSafe external battery is first charged using a PD charger, and the whole process is divided into five stages, which end in 1 hour and 51 minutes.
The new and old firmware versions of the external battery self-charging process is drawn into a curve, and the old version is faster overall, but the difference between the two is only 12 minutes.
The MagSafe external battery is adsorbed on the back of the iPhone 12, using the Apple 20W PD charger to connect the iPhone 12 to charge the two, the voltage rises from 5V to 9V into the PD fast charge at 1 minute and 49s, and the trickle charge is reduced from 9V to 5V at 58 minutes, the whole process takes about 5 hours and 13 minutes, of which the longest time consuming is the process of charging the external battery.
Similarly, the new and old firmware versions, Apple 20W PD charger through the iPhone 12 charging combination of the full curve map drawn together, the overall view of the updated curve map is 1 hour faster, but 2 hours ago the new version is slower than the old version.
In the same state, the charger is replaced by the Apple 96W PD charger, and the whole charging process is not much different from the above, and the whole process takes about 5 hours and 45 minutes.
In the comparison graph, the new firmware version charges faster, the new firmware version takes 5 hours and 44 minutes to charge the combination through the mobile phone, and the old version takes 7 hours and 9 minutes.
The charging interface is changed in position, and the Apple 20W PD charger is used to charge the combination through an external battery, and the above is the data change of the entire test process, which takes about 4 hours and 56 minutes.
In this set of curve comparison charts, the full charging time of the new version is more than 1 hour faster than that of the old version, but it is slower than 2 hours and before.
Replace the charger with the Apple 96W PD charger, and charge the combination through an external battery, the above is the data change of the entire test process, and the whole process takes about 3 hours and 28 minutes.
In this set of curve comparison charts, the difference between the two curves is small, and the difference in charging time is not large.
Charging head net summary
After the test of the charging head network, in the iPhone 12 model as an example, when using the MagSafe power supply to charge the mobile phone, whether it is charged by charging the iPhone or the charging treasure, after updating the firmware, the whole time can be reduced, the reduced time is in half an hour between an hour and a half, it seems that the update is still effective, after all, the previous full of six or seven hours of charging performance is really sorry for its price.
At present, with the opening of MagSafe magnetic module certification - MFM, I believe that soon in addition to the magnetic charger of MFM, there will also be third-party MFM magnetic charging treasure products to provide users with a more integrated charging experience, after all, MagSafe mobile power supply compared to third-party wireless charging treasure, the biggest advantage is the adaptation of UI, this experience is unique in other manufacturers' charging treasure products, as for whether it is necessary, how do you see?
