How to use YouTube faster on mobile phone?

Hi guys. I have the YouTube app installed on my iPhone but it loads so slow and buffers a lot. Does anyone here know how to use YouTube faster on mobile? I have the 32 GB LTE iPhone 5 that has the Apple A6 chipset, Dual-core 1.2 GHz CPU, PowerVR SGX 543MP3 (triple-core graphics) GPU and iOS 6.
