My iphone 3g will not charge even with a new charger can anyone help

try to CHARGE your battery first in a clip charger if it is faulty or still good but if there is no stored power,in that case,check your charger if still it gives an out put voltage,if not replace your charger with a new one or the battery.,

Once you purchase the iphone,dont use it yet.Instead of using it right away,kindly charge your IPhone with the wall charger for 3 hrs.Please dont use the Iphone while charging.Kindly check always if the battery is full.Once its fully charged then that's the time that you can use the iPhone. Once fully charged, let the iPhone's battery fully drain.Please keep the iPhone off for 2 hours.Fully charge your iPhone and allow the battery to rest in the fully charged state for two hours. (You may use your iPhone during this time as long as the iPhone is plugged in).Repeat the third and fourth step a maximum of three times if you feel your battery indicator is inaccurate.

Here are some tips for your everyday charging for your IPhone:
#1 - Charge your iPhone throughout the day when available. Charge EVERY night, regardless of charge level. This will keep your battery active, which is healthy for the iPhone's battery.
#2 - Use a wall charger or car charger w/ rated output 5V 1A. Computer chargers might not charge when the computer is in standby mode.
#3 - You cannot overcharge your iPhone. You don't need to disconnect the iPhone from the charger after it's done charging. Once fully charged, the iPhone will run strictly off of AC power and will not damage the battery.
#4 - Every two months, make sure you fully charge and fully drain the battery, in one cycle. This calibrates your battery indicator. If you fail to do this, your indicator will become inaccurate. Calibrating your battery does not improve battery life.
#5 - If you ever need to store your iPhone for any reason, make sure your battery is stored @ roughly 50% and in a cool environment.
#6 - Always charge your iPhone out of its case (assuming you can easily remove the case). Charging your iPhone inside your case will make the iPhone hotter, which is bad for the battery.
#7 - Charge your iPhone in a cool location. Charging your iPhone in a cool environment has a tremendous impact on your battery's lifespan. The colder the location you use to charge, the more charging cycles you can complete without your battery deteriorating. Avoid charging in direct sunlight.
#8 - Use properly rated chargers. Using chargers that are not properly rated will have a huge impact on your battery's lifespan. Make sure your car charger has the same rating as the official Apple charger.
The official Apple wall charger is rated as follows:
Input: 100 240V ~ 50/60 Hz 1.0A
Output: 5V 1A
Thanks!

is it brand new? plug it first on your computer then after setting the phone up, it will charge with a wall charger. it could also be that you're using an incompatible charger. a higher version of an iphone, say the 3gs won't charge if you use a charger that is meant for a 2nd gen iphone or lower only.

Could be charger, charging cord or the battery needs replacing

Your new iPhone comes with a USB cable and a wall charger in the box. If you don't have a computer, you can plug the wall charger to any socket in your house and connect your iPhone to the wall charger using the USB cable. However, if you have a computer, you can plug the USB cable to any USB slot from your computer and connect it to your iPhone.




You can also charge your device from any iPhone dock, or even those docks attached to your home theater system.

When the OnStage speakers first came out, the charger was not compatible with 3g iPods or iPhones. Newer speakers have an upgraded charger and will charge all current iPods/iPhones (up to and including iPhone 3Gs)

Bad news is that there's no way to upgrade an old OnStage.

You can test yours by trying an iPhone 3G (if you have a friend with one, for example) to see if you have the old or the new charging circuit.

Hello.

If your iPhone won't charge with your power cable, car phone charger or connected to your PC, then I'd suggest to replace the battery.

If still within the warranty period, contact your provider.

Hope this helps.

get a new charger or a replace the usb end

Held the home button and power button for 10sec, released the power button after apple icon appeared and continued to hold the home button until the USB cable icon appeared (this action prepares the iPhone for Factory reset), now connect iPhone to iTunes and follow the prompts! Note: when you restore your iPhone everything will be deleted to Factory Settings and you will only be able to retrieve your settings to the most recent back up you have stored, any data not stored in iTunes, example: (SMS, appointments in Calender), will be lost!

Keep the home and power button pressed for 10 seconds, then, leave power and keep the home button pressed...shud be able to see the charging cable logo...then restore it...
