Torrent speed slow on Android mobile device

I have installed [BitTorrent](https://play.google.com/store/apps/details?id=com.bittorrent.client) on my Xperia Z. While downloading I observed that it limits speed to 100-130 kbps max. It's same for all torrents irrespective of the number of seeders. When I tried from a laptop with same torrent and the same Wi-Fi connection, I get up to 2 MBps. Can anybody help?
