Sacrifice behind design aesthetics
In order to pursue the ultimate appearance and thinness, the internal design of iPhone has to be compact, which leads to the size limitation of some antennas and internal components. Even if the iPhone uses a high-performance baseband chip and antenna, the signal performance still needs to be improved.
Debate on baseband chips
IPhone uses Intel's baseband chip. Although the performance is good, the signal may be slightly inferior to other brands. Coupled with the patent dispute between Apple and Qualcomm, the signal problem is even worse.
Blind area of network coverage
Although the signal performance of iPhone is excellent in many countries and regions around the world, there are always some corners or specific environments where the network coverage is not perfect enough, which makes the signal stretched.
Operator factor
The network coverage and service quality of different operators will also affect the signal performance of iPhone. Although iPhone supports a variety of network frequency bands and operators, signal differences are still inevitable.
Software episode
Although the iOS system is stable and smooth, occasional software errors or system updates may also bring signal problems.
Techniques for improving signal performance
Some tricks, such as turning off some functions and using flight mode, can also help improve signal performance!
