- Troubleshooting charging problems with the HTC EVO should start with a review of how you charge the device. The two most common methods for charging the phone are through an AC adapter or a USB data cable connection to a computer. The adapter and data cable are supplied with the phone. Plug the mini-USB end of the USB data cable into the USB port on the bottom of the EVO. Plug the other end of the USB data cable into the USB port on the AC adapter and then plug the adapter into an electrical outlet. When using a computer to charge the phone, plug the opposite end of the USB data cable into a USB port on your computer. The indicator light above the screen turns yellow and the battery icon on the screen has a lightning bolt on it, indicating the phone is charging. When the battery is finished charging, the indicator light turns green and the lightning bolt disappears from the battery icon. Do not unplug the phone until it is fully charged.
- Dirty battery contacts can impede the connection to the phone’s contacts, preventing the battery from charging. To access the battery, slide your fingernail in the notch between the battery cover and the phone and lift up to remove the cover. Pull the battery out of the battery compartment. Wipe down the copper battery contacts with a clean, soft cloth and rubbing alcohol. Reinstall the battery in the phone, taking care to match the battery’s contacts with the phone’s contacts, and replace the cover.
- In time, the lithium-ion battery in the HTC EVO wears down and cannot hold the same charge it could when the battery was new. Battery degradation can also prevent the battery from charging. You can replace the battery in your phone with a new battery. Replacement batteries are available online, from your service provider and in some electronics stores. When purchasing a replacement battery, make sure it was designed to work in the HTC EVO.
- Not all charging problems are caused by improper charging, dirty battery contacts or a worn battery. If you find that your EVO still does not charge after following the troubleshooting steps, contact your service provider. The problem is with the phone itself and requires service from HTC or your service provider. You may find that the phone is still under warranty if the charging problems occurred within the first year of ownership.
