Okay so I woke up this morning and took my phone off the charger and headed to work. About 2 hours later I feel this burning sensation in my pocket and I put out my phone and this thing is burning up and the batter is down to 30%. I turn it off take out the battery, and turn it back on 10 min. later and attempt to charge the phone. I check about 15 min. later and the battery has drained to 20%. Any idea whats going on?
