The Xiaomi Redmi 3 launched in January and saw multiple revisions (3s, Pro, Prime), but the new Redmi 4 is quickly clearing the regulatory hurdles to gaining an official status.
Info coming out of China suggests that the new model will upgrade the 5 screen to 1080p resolution (up from 720p) and the 13MP camera on the back gains a second LED for its flash (the selfie cam remains at 5MP).
The Xiaomi Redmi 4 is powered by an unnamed Snapdragon chipset with an octa-core processor, a Snapdragon 430 perhaps? Its paired to 3GB of RAM and 32GB storage, same as the most recent editions of the 3 like the 3s Prime. The metal body will be available in Gray, Silver and Gold and will house a 4,000mAh battery, essentially the same as previous versions.
The phone will allegedly launch at CNY 1,300 ($190/175), close to double what the original Redmi 3 cost. By the way, the international version of the Redmi 3s is 160 currently.
I got alot of feedback coming from mi users that xiaomi phones are not reliable and consistent. The phones are just good at start and easily get broken and have lots of issues like significantly slowing down technical problems.
Helio X10 had crap battery life.
