    hmm have you try calibrate the phone?
    charge it to 100% and then let it drain until it turns off by itself
    this will usually result in correct reading of battery

    when you charge the battery, have you ever reach the 20% remaining warning and then charge and then it straight away jumps to about 30-35% charging?
    if so, its better to do the calibration mentioned above, better to calibrate your phone, or even your other li-ion battery items at least once a month
