Well, i guess this is the fall of battery endurance era. 66H endurance for 3000mah is sad.
How do you measure sunlight legibility? All reviews mentioned the dim screen, but here it's better than most flagships
Poor Battery life.
No expandable storage (microSD card slot)
No dust proof and water resistant
4G signal and data download speed are very poor.
No QHD (Poor quality screen)
OnePlus 3 problem is the heating issues
Still problems with RAM and RAM management. 6GB Ram is worthlesss. The OnePlus 3 specs are worthless. The OnePlus 3 has the worst performance of all the high-end phones.
