iPhone will boot up when plugged in but once unplugged it dies

The iPhone will boot up when plugged into the charger but once the plug is unplugged the phone turns off immediately. Also the wifi is greyed out and the phone won't connect to iTunes. I know its the logic board but does anyone have a fix for this?

I already replaced the battery and tried a reflow. I know about the greyed out wifi and the wifi chip but the first reflow didn't work. I need to try another reflow and see if that works.

It would have been nice if you would have mentioned that in your original question.

rick, the very first thing you want to do is to replace your battery. Then re-evaluate your WiFi. Make sure that you set your date and time correctly. Then try these steps first:

1. On the iPhone, turn the Airplane Mode on

2. Go to General > Reset > Reset Network Settings

3. Restart the iPhone

If that does not work, it is possible that this is caused by a failed WiFi IC. you could try a reflow and see if that will work for you. Greyed out wifi is not caused by the antenna, but a defective WiFi chip. Hope this helps, good luck.

Update

With the new information provided by you, if a good reflow has failed, you may have to replace the WiFi IC.

For the issue of the phone not holding your charge, it seems like your battery is of no use. You will most likely to have to get that replaced. As for the wifi greyed out, try these steps:

1.Restart your iOS device.

2.Make sure that airplane mode is off by tapping Settings > Airplane Mode.

3.Reset the network settings by tapping Settings > General > Reset > Reset Network Settings.

This will reset all network settings, including Bluetooth pairing records, Wi-Fi passwords, VPN, and APN settings.

4.Make sure that your device is using the latest software. To do so, connect your device to your computer and check for updates in iTunes.

If that doesn't work, you can always try to turn Airplane Mode and Do Not Disturb "ON" and power down the phone, turn back on, then turn those settings "OFF". For whatever reason this sometimes helps refresh the WIFI setting.

If all else fails and you still cannot figure the device's issue, you may have to take it to an Iphone store and have it repaired, if still under warranty, you can easily have the phone replaced at your nearest store.

If you have any further questions please come back and we will continue to assist in your troubleshooting needs.
