How can I charge up my Polaroid link 4 cell phone battery besides the usb port within it?

The t1455 does not charge from the USB port.
You can try this yourself by just plugging the camera into a USB port.

When charging the lightening bolt should be shown in the middle of the battery symbol! Are you using an original Apple charging cable and is it a USB mains or computer charger?

I assume it is on the black screen with the empty battery. If it doesnt come up with the little lightning bolt to show it is charging then it is likely the cable or charger are dead. try laptop USB charging port instead. Note I have had faulty cables that would lock up each USB port tried until I rebooted. try a friends charging rig that you know works. Another thing to check, is pocket fluff in the charge port which may prevent you inserting charging cabel correctly.

Not all computer USB ports put out enough current to charge batteries. If you have another USB port on your computer, try that. Try another computer. If that doesn't work, try an AC-to-USB charger, as you might find for cell phones.

I had a similar problem with a brand new LG Xenon. The battery charger said it was charging but the phone didn't charge. When the battery life on the phone died the phone would not turn on with the charger. I plugged it into my USB port on my laptop and the phone fully charged for real. I got 4 days before I had to recharge it again. Try USB cable to a PC to charge phone. Charger is probably bad. I am getting a replacement and will see if that works.

If they can hear you, well it still working, all it's need to do is cleaning, but opening inside the phone is a little bit complicated and beside you'll need precision tools tyo remove the screw,

just a tip:

take a look at the bottom part of your mobile phone where you are talking, sometimes it is beside the charging port or beside the USB port, you will find a bery small hole that almost there is nothing inside, see if there is any dirt blocking the way.

if none then better let the technician do the job

DramaQueen-

You charging port is probably going bad. It happens now and then.

Contact your provider if the phone is still under warranty.

If not check out the following link for solutions to the problem.

Problem With LG VU Not Charging

yes it will charge

try other USB ports on your comptuer and try it on another computer before trying to open it up

If your battery goes COMPLETELY dead, which it will do if phone is not turned OFF and not used for a long period of time, you will need to JUMP START it using you OEM SMT-5600 AC charger. Other AC chargers will not work for this purpose and neither will a USB port.

You can JUMP START the battery using a USB port by cutting off a USB cable to expost the red and black power USB PORT power pins 1 and 4. Remove your SMT-5600 battery and while the modified USB cable is plugged into your USB PORT, hold the BLACK wire to the negative (-) terminal and the RED wire to the positive (+) terminal for about a minute. Replace the battery in the phone and connect the phone to a USB PORT using a standard USB cable. The SMT-5600 charging light may not register for a while, but will eventually light amber to show it is charging, assuming your phone is recoginzed by your computer.

Note some mini USB cables DONOT carry the USB power leads through to the phone, only data. If you have a very thin USB cable, be suspicious the power leads are not being carried in the cable.

Since the USB PORT power is limited to 100ma it cannot hurt the battery, but will insert enough current into a totally flat batter to cause the battery to register a voltage large enough to alllow USB PORT charging, typically 3.7VDC.
