Why would a mobile phone suddenly stopped working?

If the problem was caused by a dead battery, it should start normally. If this still fails, try plugging the device with a different cable and charger. A broken or damaged charger could be preventing a perfectly fine device from charging. Like other operating systems, Android can hard freeze and refuse to respond.
