Step 1: Clean and use the original charger/power adapter. Different chargers deliver different amounts of power. Overcharging or undercharging the device can cause it to charge slowly (or not at all) or even damage the battery and charging abilities of the device. If you're not using the original charger, these troubleshooting steps may not resolve the issue. Check and blow into the device's power port to remove any lint or dust that may be preventing the device from charging properly. Step 2: Plug the device into a working wall outlet. Step 3: Depending on the state of your device, do either (A) or (B) below: (A) If your device turns on and has enough charge to current stay on, check for the latest Android OS and restart your device. Go to 'Settings' > scroll down to 'System' > click 'About phone' (or tablet) > click 'System updates.' Let device update and restart. If your device is up to date, manually power the device off and then back on. If your device isn't charging after powering the device on, go to the Step 4. (B) If your device shows the low battery/charge icon when you try to start your device, go through the Android boot loader to get the device to charge. With the device turned off and based on your device, do the following: Press and hold Volume Up + Volume Down + Power. The device should load a boot loader screen with a picture of an Android and the word 'Start' with highlight around it. Use the volume buttons to cycle through the options until you see 'Power off.' Then press the power button on the device to select the 'Power off' option. Unplug the device and quickly (within 10 seconds) plug it back in. The device should charge normally. If after one minute your device isn't charging, go to Step 4. Step 4: Other Troubleshooting. Try charging through a different power outlet. If possible, try charging through a computer using the USB cable. If possible, try charging through a different adapter. If possible, try charging a different device (tablet, phone, or Bluetooth) to see if the charger works. I know you mentioned that you have to hold your cable at a certain angle for it to charge. If the charging port feels loose, please reply back. Step 5: Factory Data Reset The reset will erase all your personal data, so please back up any information you want to keep.
