The Redmi 1s MSM 8228 is a lie. Redmi 1s has a MSM 8226, CPU-Z never lies (yes im a fan boy and i did my research) Here you will found solution to your Heating problem too, its a MSM 8226 overclocked to 1.6GHz (stock 1.2GHz) i was keeping my phone screen on for a half hour, my mobile didn't heated up it was 32C, I started Firefox, Nova3, SoundCloud, Stock Music app, Clash of clans and it started heating up on all of the apps. you cant hear music on background while using an application, Why? because even if you lock down the music player from task manager it still gets off try it. And i prove you that its a 1.6GHz OCed MSM 8226 Because MSM 8228 has open CL support and Open ES 3.0, Download the OpenCL Device Test & OpenCL™ Info In both app you will found its not supported and in OpenCL info you will found its MSM 8226. i've downclocked my phone to 1.2Ghz and i dont feel the heat anymore also i've changed to a Android AOSP rom and have 550MB ram always free. Downclock your phones Snap MSM 8226 is still a good deal the price point.
