Most iPhone users get an idea of the network status by looking at the signal bar that appears in the top-right corner of the screen. If it is seen four times, the network is considered strong and if it is seen once or twice, it is considered weak. But do these bars actually indicate the exact signal strength of the network? The answer is – not completely.
In fact, the signal bars visible on the iPhone are just a simple visual indicator of network status. These give you an idea of how the network is, but with the help of these bars the actual strength of the signal cannot be determined accurately.
The signal strength of mobile networks varies constantly. Many factors affect the signal, including your location, nearby buildings, being indoors or outdoors, traffic on the network, and distance from the mobile tower.
If the phone starts showing every small change through signal bars, the icon will keep moving up and down. Therefore, iPhone shows the network status in the form of signal bars by dividing it into different levels.
This is why the number of signal bars may appear different on different phones or networks, even if the actual signal strength is the same.
So it is difficult to judge how strong the network actually is in your phone just by looking at the signal bar.
If you want to see more technical and accurate information about the network in iPhone then Field Test Mode Can use. Through this, many important information to the network can be seen on the screen.
For this, first of all in iPhone Wi-Fi off Do it. After this, open the Phone app and go to the dialer.
now there 3001#12345# Type the code and press the call button.
After this Field Test Mode can open in iPhone. Here you will see many technical information to mobile network. In these, based on network technology RSRP Values like this can also be seen.
Signal values like RSRP are usually dBm Is shown in. Its special thing is that the value of dBm is negative.
usually:
However, these figures cannot be considered the same in every situation. Signal quality may vary depending on network technology, band, operator and surrounding conditions.
iPhone signal bars are a simple way to understand network health for everyday use, but they don't give the full picture of the network.
If you want to understand the actual condition of the network more closely, the technical information provided in Field Test Mode can be more useful.
So next time you see just one or two signal bars on the iPhone, do not immediately assume that the network is extremely bad. A better way to determine actual signal strength may be to look at values such as dBm/RSRP.
