Hi, so I just got the phone through the Verizon pre-owned device deal and the first thing I did after buying it was to buy the extended battery. Few things here: it literally takes about four (4) hours to charge and it discharges for six to seven hours of moderate use. My previous phone was Droid X and it's extended battery would charge for an hour an a half, two the most, so figure that is not right, it shouldn't take so long to charge a battery. Should I ask Verizon to replaced with another? So how long is supposed to last the extended battery? Also, is there other way to improve the overall battery life, besides rooting it? I have a app for monitoring the consumption and the biggest offender is the the screen, even when the phone is idle. I really like the phone, how fast it is, the prettiness of the screen, the new Jellybean, BUT I have no idea what the rooting actually does, beside allowing you to uninstall pre-loaded apps.
