It's powered by the same core hardware as many, far pricier high-end phones – the Qualcomm Snapdragon 820.
The high-end hardware means apps and games are super-responsive, but battery life is also amazing. Only the Samsung Galaxy S7 is better.
The 5.5in Full HD screen uses AMOLED tech, but isn't quite as bright or colour-accurate as other flagship rivals.
The 13-megapixel rear camera and 8-megapixel front camera are up with the best.
