3. Press *3370# to access 'reserve battery power.' False. On some Nokia phones, users can punch in special codes and toggle between speech codec modes to 1) enhance voice transmission quality at the cost of diminished battery performance, or 2) enhance battery performance by decreasing voice quality. Apparently, some users have misconstrued the latter as "tapping into reserve battery power." On that score the email is doubly erroneous because *3370# is the code for enhancing voice quality, so using it actually decreases battery life! http://urbanlegends.about.com/od/business/a/cellphone_tips.htm
