The iPhone 6S is worth around $300 on the secondary market. The phone has a lot of features that are still desirable, like a large screen and a fast processor. However, the iPhone 7 has been released, so the iPhone 6S is not as popular as it once was.

The iPhone 6S has 2GB of RAM.

There is no definitive answer, as both models have their own advantages and disadvantages. The iPhone 6S has a better rear-view camera and a faster processor than the iPhone 7, while the iPhone 7 has a better front-view camera and is water resistant. Ultimately, it depends on what features are most important to you.

There are a few things you can do with your old iPhone 6S. You can sell it, trade it in, or donate it to a charity. You can also keep it as a backup phone or use it for parts.

The original iPhone was released in 2007 and cost $599. Adjusted for inflation, that would be about $776 today. However, due to the release of newer models, the original iPhone is now worth much less and can be found for around $100-200 on eBay.

The iPhone 6S should last for around two years. Apple typically releases a new iPhone model every year, so the iPhone 6S will likely be discontinued in September 2018.

Apple typically provides support for its devices for around four years. So, your iPhone 6S should be supported until at least 2020.

The battery in the iPhone 6S is designed to last for up to two years.

There is no guarantee that your iPhone 6S will not lose WhatsApp, but it is highly unlikely. WhatsApp is a very popular app and is generally stable. If you are worried about losing WhatsApp, you can always back up your chat history.

The iPhone 6S camera is very good. It has a 12 megapixel sensor and a 5 element lens. It also has optical image stabilization, which helps to keep the image steady.
