The dual-SIM supporting Firefox OS 1.4-based Fire One Mi-FX 2 features the same 3.5-inch HVGA (320×480 pixels) resolution LCD display as its predecessor, and also packs a 1GHz processor (unspecified). The RAM however, has been upgraded from 128MB to 256MB. The camera pixel count has also been bumped-up from 1.3-megapixel on the rear camera to 2-megapixel, and 0.3-megapixels on the front-facing camera to 1.3-megapixels.
The Spice Fire One Mi-FX 2 equips 512MB of inbuilt storage, which can be further expanded via microSD card (up to 32GB). An 1100mAh battery rated to deliver 6 hours and 30 minutes of talk time, and 4 days of standby time on 2G networks, backs the handset. The battery capacity here has been downgraded from the One Mi-FX 1′s 1400mAh.
