Q:

What is "voice privacy" on cell phones?

A:

Voice privacy on cell phones is a voice encryption setting that provides greater security during phone calls. It is intended to deter eavesdroppers by making it harder to tune in to the frequency.

Voice privacy is an option found in cell phones by Samsung, Motorola and other popular manufacturers. Its effectiveness relies on the mobile carrier, which may not offer the encryption feature to users on its network, rendering the built-in setting useless. Despite this limitation, phone owners may choose to keep voice privacy enabled, a simple process for most phones. For example, Moto G owners can turn it on under Settings, while Samsung Galaxy S4 users can tap Settings, My Device and then Call.

    How do you activate reserve battery power in a cell phone?

    A:

    Most cell phones do not have battery power in reserve. However, certain brands of cell phone, such as Nokia, have an option to turn on a half rate codec mode on the phone. This reduces the sound quality of the phone but allows it to last an additional 30 percent longer. Users can also extend battery life by turning off Wi-Fi, locking their phone sooner and dimming its screen.
