Will endurance be the lifeblood of the iPhone 12?

Recently, two important rumors about the iPhone 12 have finally settled down: according to the official website of 3C certification, the battery of iPhone 12 has been officially certified, and its capacity is not as high as that of the previous generation; Jon Prosser officially released the hands-on video of the tester yesterday after exposing the screen capture of iPhone 12 two days ago, proving that the high refresh rate of iPhone 12 has not been cut off, but 120Hz is limited to the iPhone On the pro version of 12, the normal version still has a 60Hz refresh rate screen. < / P > < p > not to mention the recent revelations, from the perspective of Apple’s strategy, it is a big probability that the iPhone 12 regular version does not have a high refresh rate. After all, in the past two years, in addition to the screen display parameters, the iPhone equipped with OLED screen has little hardware advantages compared with the iPhone with LCD screen. As the iPhone 12 will use all OLED screens this year, in addition to the supply reasons caused by the epidemic situation, Apple will naturally tend to further widen the gap between the Pro Series and the ordinary version through high refresh rate. < p > < p > in the global mobile phone market, Apple’s strategy is not a big problem. Samsung, Apple’s biggest rival, also differentiates users through high refresh rate and other features on note20. However, for the Chinese market, the market prospect of iPhone 12 is not good. < p > < p > according to the data from 3C official website, apple passed four types of batteries, with the capacity of 2227mah, 2775mah, 2815mah and 3687mah respectively. Among them, 2775mah corresponds to 6.1-inch ordinary version, and 2815mah corresponds to pro version. < / P > < p > as a major power consumer, the impact of screen on high refresh rate is visible. Taking the test results of phonearena as an example, Android flagship with battery above 4000mAh can have an impact on the battery life of 2-4 hours if the high refresh rate is switched on or off, and the battery life gap is obvious in severe use. At the same time, we are not willing to upgrade the battery capacity of the mainstream Android from 45MW to the high level of battery charging, even if Samsung’s battery charging rate is less than 5000h, we are not willing to upgrade the battery capacity from the mainstream to the high level of 25mp. < / P > < p > although major manufacturers have come out with 100W fast charging, 45W charging power can at least make S20 ultra charge 30% in 15 minutes and 60% in half an hour. As a 5000mAh model, S20 ultra will not lag behind in fast charging. With Samsung’s “on the road”, Apple’s 18W has become one of the slowest in the mainstream flagship’s fast charging speed. < p > < p > take the 3000mAh iPhone 11 as an example, its 15 minute charging rate is 30%, reaching 50% in half an hour, which is behind the mainstream level. In addition, Apple’s charging deadline is very slow, and it takes more than half an hour to fill up. Apple once explained this as “battery health” and added the “smart charging” option in subsequent IOS 13 updates to further reduce the power of trickle charging *. < / P > < p > * it is worth noting that the concept of “trickle charging” used by apple and Volkswagen is quite different in battery terminology. It refers to the small current charging method used to ensure the battery life at the initial stage of charging the “low power” battery. < / P > < p > the way to charge a battery that is about to be “fully charged” with a small current should be called charging interruption. < / P > < p > due to the charge pump and the charging and discharging strategies of Android manufacturers, the “charging suspension” stage of Android manufacturers has been greatly reduced. Apple uses the reason of “battery health” as an excuse for prevarication, which is obviously not convincing. < / P > < p > not only does Apple lag behind in charging, but apple is also extremely conservative in battery selection. With the increase of charging and discharging times, the rated capacity of lithium battery will be reduced. With 80% of the battery capacity as the baseline, the iPhone can only achieve 500 cycles, while Android flagship can generally achieve 800 times. Even after 800 cycles, the latest Xiaomi 10 supreme commemorative version still has a battery capacity of about 90%. < / P > < p > it can be said that Apple has no advantage in terms of battery capacity, battery quality and charging strategy. The only way to get rid of the “urine bag” of iPhone with high refresh rate is that Apple has always been proud of its software optimization. But whether the combination of software and hardware can significantly improve the iPhone’s endurance is still a question mark. < / P > < p > from the current point of view, there are three ways for iPhone 12 to improve its endurance: 5nm process and other hardware advantages, IOS 14 scheduling strategy, and 120Hz pro motion adaptive technology. < / P > < p > let’s talk about Apple’s advantages. In the past two years, apple gave up the high-frequency design of a11 and added a new performance controller to A13 to innovate its core. These measures have increased the energy consumption of A13 by 30% compared with before, and leapt from the middle and lower reaches of mobile processors to the forefront today. Due to the significant improvement of energy efficiency ratio, iPhone has made great progress The heat dissipation problem of double-layer motherboard since X has also been alleviated. The addition of 5nm process in the future will further improve the energy consumption performance of A14. < / P > < p > despite the great progress in hardware, the biggest problem for apple at present is IOS redundancy. The endurance test results of the iPhone se equipped with A13 processor are only 1-2 hours longer than that of the iPhone 8. Apple even wrote in the introduction on its official website that the endurance of the new se is “roughly the same as that of the iPhone 8”. The improved energy consumption ratio of A13 is eaten up by IOS 13. < p > < p > in recent years, IOS seems to have lost its “beauty of simplicity” in the past, and the number of bugs has increased significantly. Despite Apple’s efforts to improve the experience of older models during the IOS 12 era, the poor performance of IOS 13 has caused many developers’ dissatisfaction. < p > < p > according to insiders, Apple’s current development team is busy developing new features and neglecting to test the stability of IOS. Craig federighi, vice president of apple, also responded to this rumor last year. He said that Apple would comprehensively reform the development process of IOS 14 and carry out many repairs and updates to IOS 13 for the first time in the next few months. However, due to the epidemic situation, there may be some problems in the development progress of IOS 14. Judging from the current beta system, the usability of IOS 14 is still good, but the control of power consumption has not made obvious progress. IOS 14 on the iPhone 12 still doesn’t significantly improve Apple’s endurance experience. < / P > < p > to improve iPhone’s life span from software, promotion technology with adaptive adjustment of refresh rate becomes the only way for apple. However, the improvement that adaptive refresh can bring is probably limited. Take note20 ultra, which adopts adaptive refresh technology, as an example, and compares it with the note20 of 60Hz and S20 ultra without adaptive refresh, it shows that adaptive refresh can only strive for 30 minutes to 1 hour more battery life for mobile phones. < / P > < p > in conclusion, even if the iPhone 12 pro with high refresh rate has A14 process support, due to the larger screen area, smaller battery capacity, and the insignificant power saving effect of ios14 and promotion, the theoretical endurance of iPhone 12 Pro may be 1-2 hours lower than that of iPhone 11 Pro. If the main purpose is to browse pages rather than watch videos, its power consumption will be higher. < / P > < p > of course, the iPhone 11 pro’s service life is in the middle and upper reaches of the Android camp, and the iPhone 12 pro’s service life retrogression is acceptable, but the fast charging slow and small battery debuffs still can’t change the iPhone’s service life completely. < / P > < p > the fact that the iPhone’s service life is not going forward or backward shows that apple is not willing to increase the battery’s stinginess for profit, but also exposes that the iPhone’s design route has encountered bottlenecks. In order to maintain the high performance of the a series, a large area of processor can only be folded, which brings about the poor cooling level of iPhone X; in order to maintain the battery life, it has added a special-shaped battery, but it has not been able to obtain more battery capacity than Android. In the view of people around, Apple has been trying to solve new problems that other manufacturers will not encounter. Xiaolei believes that this kind of “internal friction” is a manifestation of Apple’s technical strength meeting the boundary. Compared with Android manufacturers with more flexible strategies, Apple’s “dead beat” strategy is beginning to be challenged. This is the case with iPhone bangs, Intel baseband and, and even more so with the technology reform entering deep water area and mobile phone design becoming more and more sophisticated, the performance and size of mobile phone are in contradiction. < / P > < p > undeniably, Apple’s technological strength is still strong, but with the aggravation of “internal friction”, the disruptive innovation brought about by iPhone may never appear again.
