I have the same issue. I got a Blaze as an Christmas present from my wife. After only 7 months of use, the battery started draining quite rapidly to the point that it would only last a few hours. I placed it on the charger only to discover that after 20 minutes, the Blaze became quite hot to the touch and has completely died. Maybe that's why they decided to call it the blaze. I was sure this thing was going to burst into flames at any moment.
