The actual times for which the phone can be used will vary widely depending on a variety of conditions, including calling time, number of calls, email composing time, number of sent and received emails, usage conditions of Internet and applications, and network conditions. (More frequent usage or poor signal reception shortens these times. Less frequent usage extends the times.)
