Original title: feedback from the first batch of iphone11 users: high calorific value, poor signal and minor quality control problems
The iPhone 11 series has been on the market for nearly two days. The first batch of users have got the new machine and started to use it. At the same time, they release feedback on e-commerce platforms and forums. At present, the more concentrated problems include slightly large calorific value, general signal and some small problems of iPhone 11 series, but there are no serious quality control or quality problems. The following is the details.
IPhone 11 series three models
The calorific value is too large and the signal is not improved
Many users reported in the purchase comments that the A13 processor of the iPhone 11 series has a high heating capacity, including heating without any operation, hot playing games, etc. According to the data of Apple press conference, A13 bionics adopts TSMC's new generation 7 nm process and integrates 8.5 billion transistors. The overall performance is 20% higher than that of the previous generation A12. Under the same process level and performance improvement, the heat generation is bound to be greater. In addition, the iPhone 11 series adopts a double-layer motherboard design, and the heat dissipation is not as good as some Android phones with built-in liquid cooling.
It should be noted that some users feel that the mobile phone is hot when restoring the mobile phone backup using PC or icloud, which is a normal phenomenon, because the CPU of the new iPhone needs to work at a high load continuously to rebuild the database. On the other hand, the temperature of the iPhone 11 tested by foreign bloggers when playing games is about 38 degrees (100 degrees Fahrenheit), which is still a gap compared with Android phones equipped with liquid cooling (usually 28 to 30 degrees Celsius).
As for the signal problem, it is a long-standing problem of the iPhone series. After using Intel baseband, the cellular data performance of iPhone is not very ideal, which is obviously inferior to Qualcomm baseband. Although Intel announced this year that it would no longer continue the baseband business, the full series of iPhone 11 is still equipped with Intel 4G LTE baseband, which is basically not improved compared with last year.
Screen, quality control and other small problems
Every mobile phone will inevitably have some quality control problems when it is just launched, and apple is no exception. A few users buy iPhone 11 and find that there is a large gap on the side of the fuselage, which can be stuffed with an A4 thick paper, and the workmanship is not very fine.
In addition, some users found that the LCD screen of iPhone 11 is uneven. As shown in the figure below, the color deviation in the upper left corner of the screen is very obvious. Other minor problems include camera dust, frame scratches, etc., which basically occur every year when the iPhone is on sale.
It should be noted that there are not serious quality problems (such as screen color deviation, camera gray, etc.), after iPhone activation, only Apple's official website or offline stores can return and exchange goods for 7 days without reason; After other platforms are activated, they need to negotiate with the dealer and may not be able to replace or return them smoothly. Therefore, it is recommended that users who pursue perfection turn on the machine for inspection but do not activate it to ensure that there is no problem before normal use.
