If you have a Huawei P20, Huawei P20 Pro or one of a number of other Huawei handsets, its gaming performance is soon set to get better, as the company is bringing its GPU Turbo upgrade to many phones.

The upgrade, which previously had only been announced for Honor handsets, can apparently improve graphics processing efficiency by up to 60% while reducing overall power consumption from the chipset by up to 30%. So in other words games should run better and your battery should last longer.
