Nice phone battery backup is best in class in the proce segment.if yoi want more battery lifr upgradw the miui to version 7.1.1 the battery life will increase by 10 percent.
I think redmi 2 prime is better than lenovo vibe 1 because lenovo provide only battery life. This phone is very good and good battery back up, connectivity, display, camera quality back etc overall is good. And this budgeted phone having features I agree woth heating condition but that is first time when I bought. But now is no heating
