A video appeared on the Web with a detailed test of Apple MagSafe wireless charging with an iPhone 12, which revealed the delicate details of its operation. It turned out that you can get the claimed 15 watts of power only by using one single charging unit – Apple’s 20-watt adapter, sold separately. And Apple decided not to mention this in the MagSafe description, specifying only “Connect the USB-C MagSafe connector to the Apple USB-C power adapter with a capacity of 20W or more”.
The fact is that the producer of the video, Aaron Zollo, tried to charge the iPhone with the much more powerful 96-watt adapter of the MacBook Pro; but in the end, he was able to get only 10 watts. Measurement with the 18W power unit of the iPhone 11 Pro also showed a reduced 13W power.
Similarly, modest results were shown by third-party charger tests. With a 65-watt adapter, MagSafe is capable of delivering only 8-9 watts of power. In other words, Apple is pushing people to buy the new 20W charging units to replace the old ones; even if it’s a decent 18W iPhone 11 Pro charging unit.
More and more users complain about the poor battery life of the iPhone 12
As the iPhone 12 went on sale, more and more users began to get and use the new phone; and some problems began to show up. Now, many users have reported that the battery life of the iPhone 12 and iPhone 12 Pro is too weak; and the battery’s performance is not strong after being fully charged. It is difficult to count on it for a full day if you watch a lot of videos or play games.
The battery capacity used by the iPhone 12 and the iPhone 12 Pro is the same, both 2815mAh. Compared with the previous generation iPhone 11 and iPhone 11 Pro, the capacity is reduced a bit. We has a battery capacity of 3110mAh and 3046mAh respectively.
Although Apple officially stated that the battery life of the iPhone 12 and the previous-generation iPhone 11 is the same; the results of tests by some experts show that this is not the case.
Last week, Arun Maini conducted detailed comparison tests on iPhone SE, iPhone XR, iPhone 11 series, and iPhone 12/12 Pro models. At the same time, these models are all running iOS 14 without a SIM inserted; and the battery status is also good. The result is that when the iPhone 12 Pro (final battery life of 6 hours and 35 minutes) is exhausted, the iPhone 11 Pro still has 18% of the power remaining.
When the iPhone 12 (final battery life of 6 hours and 41 minutes) automatically shuts down; the iPhone 11 Pro (final battery life of 7 hours and 36 minutes) still has 14% power.
Although there are many situations that determine the battery life of a model; a large capacity can theoretically obtain a longer battery life.
