Xiaomi is holding a launch event on July 22nd which is just a couple of days away from now, and is rumored to be the unveiling day of their upcoming flagship device and successor to the Mi3, the Xiaomi Mi 4. While there is much debate about more than a few different segments of the phone the latest speculation seems to be about the Mi4's backplate, or rather what sort of material it's going to be made out of. Some of the latest rumors seem to suggest that the Mi4 could have a metal backplate of some kind, possibly steel, which comes from a translated statement from Xiaomi's CEO Lei Jun.
The Mi 4 has been thought to have a metal backplate prior to this possible suggestion from Lei Jun's comment translation which was found posted to his weibo account and stated "The journey of a piece of steel metal". The images leaked today also look to have a sort of metal backing although that could simply be the style that Xiaomi was going for. It may look like steel but the backplate may not be made up of steel at all. Looking at the pictures we can see that the Mi 4 has some pretty decent sized bezels, but perhaps they'll be easy to forget about if the device comes with the set of specs that it's so far rumored to have on board. 3GB of RAM is a noticeable trait that should be attention grabbing. It's starting to become more common as we have already seen a few phones this year with that amount, but 2GB is still the standard for most high end devices. If the Mi 4 comes with 3GB, you can expect it to be putting out some decent performance.
Other specs are thought to be a Snapdragon 801 CPU inside powering the phone, with possibly a 5-inch or even a 5.5-inch screen. There's also the possibility of a 3,000mAh battery which would do nicely to keep the phone juiced up, something that could be a good thing if the RAM and processor stats prove to be true elements of the device. Cameras are rumored to be sitting at 13MP on the rear with a front facing 5MP shooter for the occasional self portrait or selfies with friends, and of course video chat through hangouts or other apps. Storage wise, we could be looking at 16GB internally with possible expandable storage capabilities, although it would be nice if the Mi 4 starts out with 32GB instead. With Tuesday just around the corner we should know more soon.
