Replace the Dots with Numbers to See Your Cellular Connection Strength

When your iPhone connects with a cellular network, whether to access the Internet or to make calls, you should know that a weak cellular signal not only may affect data transfer speed or call quality but also requires your device to use more power — and that means your device’s battery drains more quickly. If your device’s five dot signal-strength indicator does not give you enough information about the strength of a signal (“is that 3-dot signal closer to a 2 or a 4?”), you can make your device show you the exact RSSI (Received Signal Strength Indication) measured in decibel-milliwatts. Josh Centers has written up the steps in TidBITS.
