I have an E5770 device tht seems to have a battery problem - Huawei claim 500 hours standby for this device, If I charge mine to 100%, when I turn it on less than 48 hours later, the battery charge shows 2% and rapidly turns off. Does this indicate a problem with the unit, or is the E5770 stand-by time significantly less than the manufacturer claims? There's no point in having this device as a stand-by in my bag if it cannot haold a charge more than a couple of days.
