Back when I used the Motorola Droid as my primary device, I bounced between two primary roms – CyanogenMod 7 and MIUI. Back then, MIUI was pretty rock solid and just straight out of the box (or out of the zip?), offered incredible battery life, even on batteries approaching two years of age. I’m talking 33+ hours sometimes. Now that I’m toting an LTE Galaxy Nexus, you can see how this might’ve influenced the choice of ROM for this week’s review. I wanted to answer two main questions. First, could I expect the same sort of battery life out of MIUI on my Galaxy Nexus as I had gotten on my Droid? Secondly, how had the transition from Gingerbread to Jelly Bean affected the ROM?
For those that may not know, MIUI is not your standard XDA-style ROM. It’s a closed source ROM out of China, developed by a company called Xiaomi Tech. It uses CyanogenMod as a base for it’s ROM instead of pure AOSP, a move which I personally think is pretty brilliant. Xiaomi, as far as I understand it, reciprocates by submitting patches back to CM, or at least has in the past. I’m not sure what their working relationship is today. MIUI is so heavily customized that it’s almost unfair to the project to even call it Android. It’d kind of be like calling Ubuntu Debian. Where stock Android is a fairly barebones ordeal, MIUI is chock full of features, many you’d only find in an aftermarket ROM, a clear sign of it’s CyanogenMod underpinnings.
