When comparing specifications, make sure that installing a longer-lasting battery will not make a phone uncomfortably bulky. If you expect to regularly exceed the phone's battery life, look for a phone that allows batteries to be swapped mid-call to avoid getting cut off during a conversation. In addition, you may want to find a model that can be equipped with a car kit, which allow the phone to run off a car's battery. This means that models are equipped with many more features than the average user will ever need. However, a few features can make a big difference in a phone's ease of use.
Memory is one feature that deserves close scrutiny.
Many phones offer the convenience of alphanumeric memory, which allows identifying name tags to accompany each phone number. Another feature to consider is the ringer control. There is nothing more annoying than receiving an incoming call during an important meeting. While most phones come equipped with ringers that can be turned off, more advanced models offer silent flashing lights or vibrating alerts to signal incoming calls. For those who might forget to turn a ringer back on, a phone with an escalating ringer can be a quite useful feature.
