iPhone6S is reported to have a redesigned wireless system with Qualcomm LTE chip. According to the image of iPhone 6S prototype shared by a few sources, it seems like the device will be using Qualcomm’s MDM9635M chipset which is also known as ‘9X35’ Gobi modem platform. There are a few improvements for this chip compared to the current chip which is used in the current iPhone 6 and iPhone 6 Plus.

One of the differences which are can be easily seen is the download speed when connecting to internet using LTE. It is expected that the LTE download speed will be doubled compared to the current ‘9X25’ chip that used in the current iPhone 6 and iPhone 6 Plus. The download speed is expected to be up to 300Mbps theoretically with the real world performance closer to 225Mbps or lower. The current download speed of the chip found in iPhone 6 and iPhone 6 Plus is about 150Mbps. There is no change on the 50 Mbps upload speed limit though.

Another difference is the size of the new iPhone’s logicboard. It seems to be narrower and more compact than the current iPhone 6 and iPhone 6 Plus. This could mean that there is larger battery size. With more power efficient chip combined with a larger battery and iOS 9’s new power saving features, this means that longer battery life.

The “9X35” chip is manufactured using a newer 20nm production process while the current iPhones are manufactured using the 28nm process. The new chip falls into “Category 6” cellular modems due to its speed. Thus it will allow consumers to have shorter download time as well as faster loading time despite of the uneven network response time.  On top of that, it also support other technology such as DC-HSPA, EVDO Rev. B, CDMA 1x, GSM and TD-SCDMA.

The new iPhone will only be ready in 2016.
