Sony released Xperia C4 in June this year, and it is all set to release the Xperia C5 Ultra after a few weeks. Interestingly, the two handsets could almost be in par with each other in terms of specifications except for minor differences.

Sony hasn't announced the release date of Xperia C5 Ultra, which has already been announced, but several reports have claimed that it will happen on 14 August. Sony Hong Kong website (via Xperiablog) has revealed that it will be priced at HK$ 3,298 (approximately $425 / Rs 27,088). 

It may be noted that the price of the device may differ from country to country and it will be released only in select emerging markets.

Sony Hong Kong has revealed that the upcoming device will weigh 187 grams, measure 164.2mm x 79.6mm x 8.2mm, sport a six-inch Full HD IPS touchscreen with 1920x1080 pixels, powered by MediaTek MTK6752 clocking at 1.7GHz and 700MHz ARM Mali760 GPU, and run on Android 5.0 Lollipop. It will also come with 16 GB internal memory expandable up to 200 GB via microSD card, 2 GB RAM, 13 MP rear and front cameras with image stabiliser, and 2,930mAh battery.

On the other hand, the Sony Xperia C4 weighs 147 grams, measures 150.3 x 77.4 x 7.9 mm, sports a 5.5-inch Full HD IPS LCD capacitive touchscreen with 1080 x 1920 pixels (401 ppi pixel density), powered by Mediatek MT6752 processor clocking at 1.7GHz, 700MHz ARM Mali760 GPU, and runs on Android 5.0 Lollipop. It also house a 16 GB internal memory, expandable up to 128 GB, 2 GB RAM, 13 MP main camera, 5 MP front snapper and non-removable Li-Ion 2,600 mAh battery.

If one looks at the specifications of the purported Xperia C5 Ultra and the Xperia C4, there are no significant differences. In fact, they share a few similar features like processor, GPU, RAM, main camera and operating system.

The Xperia C5 Ultra will have a bigger screen but it could come at the cost of its resolution. Prospective buyers can expect a decent upgrade in expandable memory, battery, and front camera. There are also reports that Sony might launch the Xperia C4 successor, so significant upgrade can be expected then.
