I had my phone charging overnight. It worked when I went to sleep and by the time I woke up, it didn’t. It won’t turn on at all. I bought it 2-3 months ago. Is there anything I can do to get it working?
Have you tried a long press of the Power button? It should wake up in 7 to 10 seconds…sometimes an unresponsive phone can take up to 2 minutes to respond. If you suspect, that the phone might have discharged…try to charge it with a known good charger for 20 minutes and repeat the above steps of pressing on the Power button.
In addition to the advice you got from @amitl a good test of the charger is whether or not the current charge level appears for about 10 seconds shortly after the charger is plugged in.
If you aren’t seeing this there is a good chance you have a bad charging cable, a bad charger, or the charger is plugged into an outlet that is switched off.
