That exclamation mark means the battery is bad or has a bad connection inside the device. If your battery is user-serviceable you could try removing the back of the device and checking the connection for corrosion or looseness. Depending on how old your device is, it just might be time for a new battery.

First way is from the Setting > Backup and restore.
