Going through the suggestions, I am also inclined towards thinking it is a dead battery

Li Ion batteries have a protection circuit that kicks in when the discharge falls below a certain level. It requires certain current to be applied to it before charging can happen. This is called "Boosting". How to awaken sleeping Li-ion explains it and suggests ways

In case you don't have access to such chargers, try switching off the phone and then charging in the hope that it would get enough current to kick start charging. The battery is presumed dead, so leave it like 6 hours on charge in switched off condition

Coming to charger, I agree with what others have said but if you can see the phone charging rate from specs (e.g. gives 1600 mAh current to charge) and your current charger also gives the same or slightly higher, and is 2A , 5V wall charger, it is fine but don't make it a regular practice. In this case, I feel if the current reading is slightly higher it would actually help. This would answer more questions on using chargers meant for a different device Is my phone liable to explode if I charge it with a charger that came with a different phone?

All the best
