Well, one of the features that Sony dibanggakann sound output problem is xLoud features that will enhance the power of the speakers said.

Battery Life

Xperia manifold N equipped with Lithium Ion battery with a capacity of 1290 mAh. With the capacity of this and the type of processor that is said is more energy efficient, we feel battery Xperia U is like most Android phones that have only lasted a day or even less, when used with normal use. But it also depends on the signal conditions, and the use of each user. Moreover you inevitably have to use light effects burning at the bottom of the phone, because we did not find a setting to turn off the light effects.


Armed with a 1GHz dual core processor as well as the clarity of the screen and features a Sony owned the other, especially the prices are not priced too high, we think this phone is suitable for those of you who want the Fun Android phone and have a competent performance. But one factor that unfortunately, the limited memory that can be used. Because as we know it today has a lot of multimedia content that supports HD resolutions and consequently also the memory usage will increase. But for those of you who are not too concerned with memory, then the issue is not a problem for you, because in addition to issues of phone memory is very feasible for you to have.
