New battery for samsung rugby 2 won't stayed charged

SOURCE: Batteries draining problem?

this problem can be caused by many factors. Use of the phone can drain battery life for example if you use the phone for browsing the web or as an mp3 player, even to make or recieve calls the battery life will not be as long as it would if just on standby. also if the battery hasn't been conditioned or is being over charged this can also lead to short battery life.To resolve the problem try conditioning th battery, basically let the charge drain completely out of the phone until the phone actually switches off, then charge the phone for 24 hours. Next time the battery goes ded only charge for the recommended charging time (this info can be found either in your phone user guide or by contacting the customer service department of your network provider).

Well if it's new, then I would take it back to the store from where you bought it. It will be under warranty so, if something is wrong you should be able to get it swapped out with a working one.

It is probably the charging port. It seems to be a common issue with this model of phone.

If it is the charger port on th eD900, You have 3 options.

1. get it repaired, under warranty if possible
2. Get a new one
3.Get an external battery charger and charge battery separate from phone.Another battery and charger will set you back about 10 dollars on ebay
