I bought two of these phones, both got less than a day and a half of stand-by battery life. Called Virgin and they said that early models were OK, but there's a bad batch out there now. Buy the "Audiovox 8610 Vox Prepaid Phone" instead, it's comparable in size and features and its stand-by battery life is much closer to the 7 days advertised (and you can easily get an extended battery if you need even more time).
