After much back and forth I have but then decided to buy me the Alpha. What were always held me back something which partially present statements about poor battery performance, why some (very winy) about negative report is beyond my knowledge. I have no problem, for many device had but that's really good, under normal use, the device holds loose two days, but I invite still mostly in the evening. The Alpha lasts longer than my Galaxy S4. mA hours or not, the device simply consuming less power. Device is good, also the display, no idea why some reviews and some negative positive report, only can say: media are just so, everyone should form his own opinion about it, about the media you get rare ... no further comment ....
