Introduction
Apple Since iPhone 12, it has added MagSafe magnetic wireless charging function to iPhone, and has launched a variety of magnetic protective cases, magnetic chargers and other peripheral accessories. Currently, the full series of iPhone 12, the full series of iPhone 13 and the new iPhone 14 support precise alignment magnetic wireless charging.
last issue, the Charging Head Network conducted actual tests on wired charging of iPhone 14 series products that have arrived, and the battery capacity of iPhones of all generations has been counted. Interested friends can check it out; today, the Charging Head Network has not discovered a new world in wired charging, so will there be any unknowns on MagSafe charging?
Product introduction
iPhone 14 Pro Max retains almost the same design as its predecessor, but the bangs on the front are changed to "pill" design, called "Lingdong Island", but the size is smaller than iPhone 13 Pro Max. In addition, the screen border is more skin-friendly and delicate. The screen is also 6.7 inches, and it still uses a super porcelain crystal panel design. The side buttons on
are slightly different from those on iPhone 13 Pro Max and iPhone 12 Pro Max, so personalized mobile phone cases cannot be universal.
did not launch a new MagSafe magnetic wireless charging cable at the press conference, so only the old ones are available, and can be purchased at the official Apple store at present.
uses MagSafe charging cable + original 35W charger to charge the iPhone 14 Pro Max, and the actual charger output power is 18.7W.
uses MagSafe charging cable + original 35W charger to charge the iPhone 13 Pro Max, and the actual charger output power is 18.57W.
MagSafe Charging Test
This time, the previous generation "maximum cup" model - iPhone 13 Pro Max, were tested under the same circumstances, namely 25℃ ambient temperature, the new 35W charger, the same MagSafe charging cable, etc.
iPhone 14 Pro Max
This is the data for the entire charging process of iPhone14 Pro Max using the original 35W charger and MagSafe charging cable. The entire process can be seen from the curve. When the handshake is at a 9V voltage level, the charger is stable at a power of about 18W to 12 minutes, the current fluctuates, causing the power to fluctuate in the range of 11-19W. After that, when the charging is 56 minutes, the power tends to stabilize about 16W; finally the charging ends at around 2 hours and 18 minutes, with a maximum power of 8.97V 2.14A 19.22W (the output power of the charger end).
draws the entire MagSafe charging process into a curve chart. It can be seen that the iPhone 14 Pro Max is charged 36% in half an hour, 67% in one hour, and 89% in one and a half hours. It takes 2 hours and 18 minutes to fully charge.
iPhone 13 Pro Max
This is the data of the entire charging process of iPhone13 Pro Max using the original 35W charger and MagSafe charging cable. The entire process can be seen from the curve. When the handshake is at a 9V voltage level, the charger is stably output at a power of about 18W to 16 minutes, the current fluctuates, causing the power to fluctuate in the range of 11-19W. After that, when the charging reaches 44 minutes, the power tends to stabilize within the range of 14-16W; the charging ends at around 2 hours and 26 minutes, with a maximum power of 8.97V 2.11A 19W (the output power of the charger end).
draws the entire MagSafe charging process into a curve chart. It can be seen that the iPhone 13 Pro Max is charged 30% in half an hour, 57% in one hour, and 79% in one and a half hours. It takes 2 hours and 26 minutes to fully charge.
Charging Head Network Summary
Judging from the above-mentioned test results of the MagSafe wireless magnetic charging cable + original 35W charger, this year's new iPhone 14 series optimizes and adjusts the stability of wireless charging compared with the previous generation "super large cup".
controls the charger, charging cable, and test environment to the maximum extent. Through the power change curve chart, it can be found that when the iPhone 13 Pro Max is wirelessly charged, the current fluctuation amplitude is greater, resulting in a larger power change range; and in terms of charging time, it is also necessary to consider that the battery capacity of the iPhone 14 Pro Max is 4323mAh and the battery capacity of the iPhone 13 Pro Max is 4352mAh. Therefore, the 8-minute time difference seems to be negligible.
From the current perspective, for iPhone users, the wireless charging function of iPhone 12, 13 or 14 series can avoid frequent plug-ins and unplugging of cables, and can absorb and charge when close to it, making the user experience more comfortable; while the charging process of the 14 series is relatively smooth, with a shorter time of internal consumption of 0-80%.
