Time Remaining / Time Remaining

When we need a flashlight to go out, but we don't know how long it can use electricity.If you find it has no electricity halfway, right now you will be annoyed that why i havenot recharge it before going out?
"Time Remaining" is a flashlight design and increases the function.of showing the length of time that the power can last. When the flashlight can continue long working time, the time’s color is blue; when the
flashlight only lasts for 15 minutes, the time’s color is red, so we should recharge it.
