Apple's upcoming device, the iPhone 7, is expected to be released this coming September. With the built-up hype around this device, a ton of rumors are bound to appear. However, if all these prove to be the truth, then it might be clear that the iPhone 7 will prove to be different from its predecessors.

One of the most talked-about rumors is that this iPhone will come in three different versions: iPhone 7, iPhone 7 Plus and iPhone 7 Pro. Apple will most likely use Pro as their more favored model, and various rumors state that the Smart Connector and the headphone jack will most likely be included as some of its exclusive features.

In light of this, it follows that the normal iPhone 7 will not have any headphone jack. This projection is supported by the release of the iOS 9.3 beta's feature, which states that the jack will be non-existent. Furthermore, a research memo for the iPhone 7 acquired by the AppleInsider shows that, while the headphone jack is gone, it's going to be replaced by an extra speaker similar to an iPad Pro. Also, most of the leaked pictures of this device online don't feature a headphone jack.

Additionally, one of its most important possible features is its longer battery life. This is supported by leaked images from a Chinese website Digi.tech.qq.com, which features a battery with a 7.04 watt-hour capacity. The iPhone 6 has a 6.61 watt-hour battery, and using this comparison, the iPhone 7 will have a comparably longer battery life. Also, it's suggested that the newest iPhone will have a huge 3,100mAh battery, which is roughly around 13% larger than the iPhone 6 Plus. Couple that with the planned iOS tweaks as well as future improvements in the processor efficiency, the increase in battery life will definitely grow.
