Mobile phone battery will be burnt do?

Users questions:I am using Philips 9 @ 9 + + mobile phone. Last night, with the mobile phone first wife via cell phone as a backup transformer battery, charging began, I am worried that the charge can not be very good, but also looked to see if the normal charge. Examination was normal, it will continue to charge cell phone off (I frequently charge is mainly worried about lateThe impact on the receiving unwanted phone break). However, after getting up this morning and found that after charging the battery can not be used, seems to be that there is no sufficient electricity. Afterwards on the charger charging, there is no response. My question is: 1. You have encountered such a problem? 2. Battery charging process, will "burn" out do? 3. Why is this so? Whether or not you answer my question, I have to thank you!
