Hey guys need suggestions for a phone:

Budget: RM 1300 - RM 1800(Cheaper better obviously)
Brand: Any will do (Android)
Spec: Prefer performance phones for multitasking and a good battery life. Not picky with camera anything decent will do. So basically powerful processor and generous RAM (3GB and above)
Size: Any but not too large.

Currently preference is towards the OnePlus 2. Does it fit my requirements? Any better suggestions?

Thanks Sifu's
