According to some recent leaked reports, Apple may launch its new iPhone 6S mini soon. This upcoming model is expected to have an unsurpassed battery life in comparison to the battery power of Apple’s iPhone 6S and 6S Plus flagships.

According to latest reports from a Chinese website, MyDrivers, the 4-inch iPhone could be the biggest salvo among rival smartphones that have humongous screen sizes and powerful batteries. Apple’s iPhone 6c is called the iPhone 6S mini and it claims to have a handful of great features that include battery life, design and performance.

The new phone will use a similar 2.5D slightly curved glass for its screen, like the iPhone 6S and 6S Plus. Rumours are doing rounds that the upcoming iPhone 6S mini could pose a threat to the iPhone 6S and 6S Plus , by bringing down their sales.

The iPhone 6S mini is said to have a smaller battery that is 4.25 percent smaller in size than the one in the iPhone 6S. The good news is that since the iPhone 6S mini has smaller display size, every pixel in the display consumes lesser battery power. The device has up to 30 percent lesser pixels than the iPhone 6S. As a result of this, the iPhone 6S mini needs lesser battery power than its iPhone 6S counterpart. This is why the device enjoys an amazing battery life, reports Forbes.

According to TechMalak, the speculated features of the iPhone 6S mini are a 4-inch screen size packed with 1136 x 640 pixels, a 1,642mAH battery, a 2GB of RAM and an A9 chipset inside. Apple is expected to start a mass production of the iPhone 6S mini by February.

The tech company is expected to release the iPhone 7 with an A10 chipset inside the phone later this year. The iPhone 6S mini leaks hint that the phone will launched at a starting price of 4,000yuan or US $615 (approx. AU $850), says Trusted Reviews.
