In 2010, Apple even admitted it had made a mistake in its formula for calculating signal strength on the iPhone 4. “It’s not as simple as four out of five bars is some absolute standard that ...

Currently, the LTE signal bars are computed from the cellular signal strength in your particular location. This can be seen in Android's Settings app, expressed in dBM or decibels per milliwatt.
