They are telling blow. Oneplus 5 has 3000 mah battery but it actually has 3300 mAh battery. I personaly love oneplus brand. Oneplus is actual flagship killer. It has brilliant rare camera. If you are compare iphone 7plus oneplus 5 has better camera. It has monster 6, 8 gb ram. They upgrade networking system now oneplus 5 runs all over the globe. They also upgrade low light camera performance. Price of this model is very good. And features of this phone is outstanding. I have oneplus 3T. And I know oneplus is better than other brands.
