You may be experiencing one of these issues:

• Your phone isn't charging fully to 100%.
• Your phone stops charging before it is fully charged.
• Your phone does not display a charging LED indicator while charging.
• Your phone only charges when in certain positions or when held.
• Your phone's battery life is reduced or shorter than expected.

For best charging performance, it is strongly recommended to use only the original HTC charger, or an HTC-approved charger.
NOTE: Some phones do not have an LED indicator. If no on-screen indicator appears, pressing the POWER button should cause the on-screen display to show a charging indicator. If the phone does not appear to be charging and will not power on, follow these steps:

1. Hold VOLUME UP, VOLUME DOWN, and POWER buttons for up to two minutes.
2. Check for signs the phone is charging.
   If the battery is very low, it may take up to 2 minutes for the LED to change. The LED indicator may blink repeatedly to indicate charging and will become solid after several minutes.
   If the LED is blinking, the phone is charging but cannot power on until the LED is a solid color. Wait until the LED is solid before attempting to power on the phone.

In some charging situations, the charger may detect the voltage as being too low and will stop charging the phone even though it is still plugged in. System software updates should address this problem.

To ensure the phone is fully updated, follow these steps:

1. Go to Settings and select System Updates. The exact path will differ depending on your phone.
   These are the three typical paths:
   
   Settings > System updates > HTC software update
   Settings > Software update
   Settings > AT&T Software Update
   
   

2. Select HTC Software Update to check for new updates.
   If an update is available, follow the on-screen prompts to download and install the update.
   If no update is found, confirm that the phone is on the latest software version navigating to Settings > About > Software Information.

Damage to the charging port, cable or charging adaptor may also result in erratic charging behavior (such as only charging in certain positions or when held), or the device being unable to charge at all. To check if a faulty cable or adapter is causing the issue, follow these steps:

1. Check the charging port for damage or debris; bent pins, dirt or lint blocking the port
2. Check the current cable and adapter for damage; kinks or frays in the cable, or if there are bent connection pins in the charger.
3. Use another charger with the correct voltage and amperage ratings for the device; note that some USB ports do not supply enough power for adequate charging.

Some issues can also be resolved by power cycling your device. Follow these steps:

1. Press and hold the POWER button until the Phone Options appear.
2. Select Power Off and wait for the device to fully turn off.
3. Wait for a few moments, and then power the device on by pressing and holding the POWER button.

Check if the device is able to charge in Safe Mode. See How to boot into Safe Mode.
