Why does the Motorola Moto G (2nd Gen) heat up after short use?

My mobile,Moto g2 is getting heated aftr a short use of 10-20 minutes even offline...tried it in flight mode which gives less trouble...but when changed back gives the mobile holding person the worst fear of getting it exploded. charging on its normal charger takes almost a day for full batter meanwhile only 4-5 hours to get it drained.p lz help me resolve the prob

If you experience your phone heating up too much, you should immediately get it repaired. Send it back to Motorola so they can check your phone and find out what's wrong with it. Most possible cause I can think of is it has a defective battery.
