battery life

Regarding battery life, despite owning 2,050 mAh battery capacity, but the actual time used on Redmi 1S quite tight, of course, the machine remains in service users during daytime working hours. If you are familiar with the style used up "full speed" is Redmi 1S really need to consider.

On the machine's camera, this is causing you to be surprised when after 8 megapixel camera for picture quality is quite detailed but clear water vapor image to pale in comparison to reality. 1.6 megapixel front camera also like image quality "selfie" of Redmi 1S better than the same product range as Prime Mobiistar Zenfone 5 or 508.

Redmi 1S also proved superior with respect ASUS Zenfone 5 players.

When you try to test the performance of the machine on the AnTuTu Benchmark v5.5, to attain a score of 20,344 points, the relatively high price range, even in one of the other test, Redmi 1S also proved superior with respect ASUS Zenfone 5 players.
However, because it is one cheap products, so in the long running time, it can not avoid the phenomenon of "warming" in the cluster camera. With the fun, we may temporarily paralyzed Xiaomi 1S Redmi list smartphones dedicated to winter.
