Great phone at a amazingly affordable price! Battery Life This phone has a relatively good battery life during normal usage. With Wifi on constantly, it lasts for about a day and a half. Though, certain apps such as more sophisticated games or video watching may drain the battery relatively quickly. Display/Screen Quality The display/screen quality is nice. There is a pretty decent auto brightness adjustment function. Call Quality Call quality varies depending on what mode it is on. The wifi calling option though wonderful, may be shakey at times despite strong wifi signal. Ease of Use The Windows 8 opertaing system allows for a relatively simplistic user interface. Everything is pretty straightforward. Durability So far, I have not encountered any problems with the phone despite a couple of apps crashing upon resuming from a locked screen. Design This phone has a really slick design that makes it comparable to any iphones.
