Will the newly bought electronic watch run out of power after long use? Or the power is reduced.

The power has dropped. After all, your watch keeps running. If it is an ordinary battery, it may be dead after a long time, depending on how long you have used it.

The battery of an ordinary electronic watch can work for two or three years. If it is a solar electronic watch, you don't have to worry for a long time. As long as there is light, it can be charged, and the display screen will automatically turn off in dark places ~
