Why isn't it working?

Hello! So i got this Beats pill 1.0 for an year now and some time ago the battery crashed or something and it worked only why it was plugged to a external battery or any other power sources. I went on a trip and i dropped the pill from like 1 m by accident. Now the pill doesn't work if i connect it to any kind of power source. Is it the battery or what else could it be ? Please help. Thank you :)
