Enhanced Full Rate Codec (EFR) :

Enhanced Full Rate will give you much better sound quality when you enable it. The new Enhanced Full Rate CODEC adopted by GSM uses the Algebraic Code Excitation Linear Prediction compression technology. This technology allows for much greater voice quality in the same number of bits as the older Full Rate CODEC. The older technology was called LPC-RPE (Linear Prediction Coding with Regular Pulse Excitation). Both operate at 13 kilobits.(but you take up more space on the network, so they can charge you more). Also this improves call quality but decreases battery life by about 5%.

EFR will be activated after a reboot of the phone (consumes more power).

EFR will be switched off after a reboot of the phone.

Half Rate Codec (HR):

Half Rate will give you bad sound quality, which gives the service provider the opportunity to have more calls on the network; and you might get a lower charge from them. (Will give you 30% longer talk - time).

Half Rate coded will be activated after a reboot of the phone (better standby time).

Half Rate coded will be de-activated after a reboot of the phone.
