From the beginning of the existence of the brand OnePlus, phones produced by this company were advertised as "flagship killers". This sentence in practice meant that OnePlus makes phones with a similar specification as the most powerful devices of companies such as Samsung available for a much lower price. Chinese company was founded in 2013 and quickly gained a lot of fans, mainly due to the really solid production of all phones that appeared on the market, but with a matter of time happened what was feared from the very beginning - with improvement of company's popularity, prices of equipment went up. At the moment it's hard to call OnePlus 6 a flagship killer, since you have to pay about 520$ for it in the strongest version, which is quite a large amount of money. However, this is not the end of prices increase, because upcoming OnePlus 6T is going to cost even more.
On the Internet some websites already published a list containing all variants of OnePlus 6T that will appear on the market with their prices. The cheapest version equipped with 6GB RAM and 128GB of internal storage will cost around 520$ (37.999 INR), an option with 8GB RAM and 128GB internal memory will be valued at around 560$ (40.999 INR) and the most expensive option with 8GB RAM and 256GB internal storage will cost more or less around 610$ (44,999 INR). This is a big jump compared to the previous model, OnePlus 6, but soon we will see whether it is worth to pay so much for the upcoming OnePlus 6T because premiere of this device is planned for 30th of October.
