The latest rumors from OnePlus company are about the upcoming OnePlus 3T smartphone which should replace the OnePlus 3 model. New OnePlus 3T is expected to cost 20% more than its predecessor and it will be powered by Snapdragon 821 processor. However, this may be only refreshed version of OnePlus 3 with more powerful components. A similar strategy was chosen by Xiaomi when they have decided to release the newest flagship mobile, i.e. Mi 5s.
However, people are waiting for something new with next generation chipset and new features. The newest leaks about OnePlus 4 flagship smartphone come from Weibo and contain very interesting informations. The upcoming flagship killer is expected to be released in June of July next year, so we have to wait at least 8 months to see OnePlus 4 mobile. It should be powered by Qualcomm Snapdragon 830 chipset (the same will be used e.g. in Samsung Galaxy S8). This processor is manufactured by Samsung, but it looks that the Korean company has some issues with timelines.
I hope that this will not delay the release date of OnePlus 4.
Qualcomm has also the backup plan and they are considering the possibility of switching the production to TSMC. However, these rumors are not confirmed, so maybe everything will be delivered on time. The highest clocking frequency of processor used in OnePlus 4 will be 3.0 GHz and it will also have 4 000 mAh battery. Of course, the device will come with preinstalled Android Nougat operating system.
