Battery Cool Down

In very limited circumstances, such as where your phone has been exposed to extreme heat, you may see “Cool Down” messages. To avoid possible damage to your battery and phone, you should follow the onscreen instructions until the phone is within its recommended temperature range. When your phone is in “Cool Down” mode, only emergency calls can be made.
