When the cellular cnecti starts to play hide and seek my iPhe, I take the help of "Field Test Mode" to evaluate the actual signal strength the device because the signal bars are not very useful. Apple has slightly changed its features in the latest versi of iOS. Unlike previously, it no lger displays the cell signal as a number in the iPhe status bar. So, how to use Test Filed mode in iOS 11 to know the signal strength the iPhe?
Despite the noticeable change, you can still see the cellular cnecti in decibel milliwatts (dBm) in iOS 11 or later. Although the process is the same as before, you can not make the number appear in the status bar. I wish there was a way to do it! Anyway, let's see how it works:
- Make sure your iOS device has an active cellular cnecti that allows it to access and use the field test mode to measure signal strength.
- Note that you will ly be able to check the power of 4G recepti the nearest cell tower. the iPhe with an Intel wireless modem. I'm sorry, you can ly get it the device with a Qualcomm modem.
- Although you can get similar data reads both versis, ly the device equipped with Intel wireless chips will display dBm.
- The devices which you can see the cellular cnecti in decibel-milliwatts are iPhe X: A1901, iPhe 8: A1905, iPhe 8 Plus: A1897, iPhe 7: A1778 and iPhe 7 Plus: A1784. Go to this post to check if the …
