Problems like these are unavoidable when large software upgrades are installed on mobile devices, including the **iPhone [6s Plus](https://answers.mindstick.com/qa/51548/what-are-all-the-differences-between-the-iphone-6s-and-iphone-6s-plus-which-should-i-buy).** Others have reported the same black screen issue on their iPhone, along with other symptoms such as being stuck on the Apple logo for an extended amount of time, as well as a red or blue screen. In this scenario, the iPhone was able to power on but could not startup for some reason. \ One theory for why your iPhone 6s Plus is stuck on a black screen after updating to iOS 10 is that something in the phone's present system setup is incompatible with the new platform, resulting in the device's strange state. \ **Insufficient memory** or the remaining accessible storage space on your iPhone is not enough to allocate the actual file size of the update is another possible explanation why your iPhone is stuck on a black screen with a spinning circle. As a consequence, performance issues such as an iPhone that is sluggish, unresponsive, frozen, won't turn on, or powers on but can't get beyond the start-up process may arise. --- Original Source: https://answers.mindstick.com/qa/50947/why-does-my-iphone-6s-plus-won-t-turn-on-stuck-in-black-screen-during-startup Copyright © MindStick Software Pvt.
