In my sony ericsson P990i cellphone when i charge it it will not be charged.the charger and battery is ok .so please tell me what should be the problem and the way to solve the problem. thank you

Check the pins on your charger and the connector on the phone. if they are in order, then u have a problem with your charging port which is on the phone. and if that is the case, you may have to replace the charging port. alternatively, you can get an external charger and use it to charge the battery. meaning you will get an extra battery to swap with the other when one is on charge. but if this problem deteriorates, it will be running down your battery,making it to discharge faster.
