iPhone14 has been officially released. The core parameters of this series have been summarized and analyzed in previous articles, and other media have also made similar explanations. In this article, we will focus on some detailed parameters about the iPhone 14 series that were not explained at the press conference. I hope it can help you.
In order to make the article more organized, this article will use the form of a question and answer. Is the memory capacity of
01 and iPhone14pro 8G or 6G?
Answer: 6G is not 8G, but upgraded to LPDDR5 6400
iPhone14 Normal Edition and iPhone14MAX Edition have been confirmed to be equipped with 6G memory. Compared with iPhone13, it has been 50% (2G) increased by Kuo Mingchi (Kuo Mingchi's accuracy of iPhone's revelations is close to 100% ). Many people are more concerned about the memory capacity of the iPhone 14 Pro version. According to the information leaked on the latest Xcode 14 beta version, the iPhone 14 Pro series is equipped with 6G memory, not 8G.
In other words, the memory capacity of iPhone14Pro has not been improved, and it still maintains 6G capacity. However, according to the words of , the memory version of iPhone14Pro series will be improved from LPDDR4X to LPDDR5.
Regarding this, we can also get clues from PPT at the iPhone press conference. According to the description at the Apple press conference - the GPU bandwidth of the A16 processor has been increased by 50% , and the upgrade from LPDDR4X 4266 to LPDDR5 6400, and the bandwidth has just increased by 50%, which is completely consistent.
02, A16 How much improvement is the Bionic processor compared to A15?
Answer: CPU single core 9%, multi-core improvement by 13%, GPU performance unknown.
A16 Bionic is exclusive to the iPhone 14 Pro series, and its performance improvement naturally attracts much attention. According to the data currently exposed by Geekbench official website, the single-core CPU running score of Apple's A16 processor is 1887 points and the multi-core running score is 5455 points. In contrast, the A15 processor has a single-core running score of about 1728 points, and the multi-core running score is 4790 points.
can be concluded through data comparison that the CPU single-core performance of the A16 Bionic processor is about 9% higher than that of the A15, while the multi-core performance is 13%. This running score is basically close to the final real running score data and is very reference-oriented.
As for the performance of GPU, no scoring platform can give accurate answers, but according to previous forecasts, the GPU performance of the A16 processor is about 15% higher than that of the A15.

A15 running score
That means that the A16 processor will become the generation with the smallest comprehensive improvement in the history of Apple's A series. Of course, when facing the Android camp SOC, the A16 processor still maintains a great advantage. The specific running score is as follows:
A16 processor: single core 1887 (100%), multi-core 5455 (100%)
Snapdragon 8+ processor: single core 1311 (69%), multi-core 4070 (74%)
Tianji 9000+: single core 1322 (70%), multi-core 4331 (79%)
03, how big is the 48MP sensor area of iPhone14Pro?
Answer: is about 1/1.3 inch, basically equivalent to Samsung GN1, IMX707
iPhone14Pro in addition to the appearance changes, the biggest improvement is mainly focused on the rear camera. It finally upgraded the ancestral 12MP main camera to a 48MP main camera, and finally used a Senser that supports multi-pixel four-in-one. So how big is the size of this sensor and whether it can reach the level of Android flagships will naturally become a focus of consumers' attention.
Although there is no clear disassembly report yet to confirm how big the size of the CMOS sensor on the iPhone 14 Pro is, we can use data to calculate it.
According to the information at the press conference, the single pixel area of this CMOS sensor (after 4 in 1) is 2.44um, which means that the unit pixel size is 1.22um. Combined with its 48 million pixels, it inversely deduces
Note: The formula for calculating the unit area of sensor is the sensor width* length/pixel. The result of
is about 1/1.3 inch.
As a comparison, the Samsung GN1 50-megapixel unit pixel area equipped on the VIVO X80Pro+ is 1.2um 1/1.3 inches, and the IMX707 50-megapixel 1/1.28-inch 1.22um equipped on the Xiaomi 12SPro. The area of these two sensors is very similar to the new sensor equipped on the iPhone 14Pro.
Of course, there is still a significant difference compared to the Sony IMX989 equipped with the Xiaomi 12SUltra. The IMX989 has a unit pixel area of 1.6um, and it can reach 3.2um after multi-pixel 4-in-one, which is much larger than the new main camera equipped on the iPhone 14 Pro.
04. How big is the battery capacity of the iPhone 14 series?
According to the reliable information currently obtained, the battery capacity of iPhone14 is as follows:
iPhone14 series:
iPhone14: 3279mAh Improve 72mAh
iPhone14plus:: 4325mAh (the largest battery in the iPhone14 series)
iPhone14Pro: 3200mAh; improve 105mAh
iPhone14ProMax: 4323mAh 29mAh
iPhone13 series:
iPhone13 is 3227mAh
iPhone13Pro 3095mAh
iPhone13ProMAX: 4352mAh
Overall, , iPhone14Pro's battery capacity has the largest increase compared to the previous generation , and other versions are still in the spotlight. iPhone13Plus has the largest battery in the entire series and even the entire iPhone history, as well as the strongest battery life expectancy.
05. Can the satellite communication of iPhone14 be used in the country?
Answer: cannot
iPhone14's satellite communication function can only be used in North America and Canada and is not supported in China.
06, has the charging power of the iPhone 14 series increased?
Answer: No.
The entire series of iPhone14 is equipped with 20W wired fast charging and 15W wireless fast charging, and has not been upgraded.
END Hope it can help you
