If the cell phone battery is more than 3 - 4 years old then the battery could be worn out.Rechargeable batteries have a finite number of charge and discharge cycles andwill lose their charge capacity over time, i.e. won't charge to 100% and graduallythe charge reduces until the battery won't charge up at all. OR The batteryshows a 100% charge but when the adapter is disconnected the battery drops offto zero capacity in a very short time. If the battery drops to an unacceptablecharge level then the battery needs to be replaced.

Moto Razr components where taken off the assembly line years ago and all parts used are refurbished or stockpiled.........you have a bad battery, case closed........the razr has a few common flaws...... ear piece, LCD, and battery tends to go out without notice and on a rare occasion wont work right out of the box.....Working at Sprint PCS I saw 1 out of every 15 Razrs have problems straight from the box....take the phone back to the staore and they will giv you a new battery as they should be away of the hiccups associated with this device!!!! :D
and by the way, 3-4 hrs use from a 15 min charge is awesome.......just your battery has an internal flaw that is causing it to transfer too much power.....(i.e. thats how it is able to charge so fast, but also why it dies so fast) if you have another razr laying around try that battery as long as the lettering on the battery is the same....fr example : a battery with the code bt50 and br50 are not interchangeable.
Good Luck and pls rate this post!!!! :D
Ok first of all you should never let a phone die out of charge at all.IF it dies out of charge there are chances it might charge again once you charge it but in some cases it wont, you need to boost your battery just like jump start your car.It cannot be done anywhere except some service centre. If you are not taking to your service center , then you need to buy a new battery.
HEY THOSE CHINESE CHARGER ARE NOT GOOD.. THEY SUM HOW NEVER CHARGE THE BATTERY PROPERLY ND THE BACKUP IS LESS. CHARGE USING UR MOTOROLA CHARGER ND IF U STILL EXPERIENCE PROBLEM THEN U BETTER GO TO MOTOROLA
Their website says only 6 hours of talk time for that battery. Could be that's all your gonna get from it. Every phone I've ever owned has needed to be recharged every other day and sooner if it's used more.
you simply fried your battery by overcharging it. Just get a new one, let it fully charge and fully die twice before you start normal charging. Then you will want to only charge it for about 2 to 3 hours or find a charger that has a smart chip that tells it when to stop charging once the battery is full.
