Smartphones need per minute that they really used, approximately 1% battery. So my rule of thumb. For this, the power consumption at idle, which can also be immensely depending on network coverage. Therefore, for my phone I already longer a small battery pack, so I do not constantly need the socket on Barcamps etc.. Now I'm playing well and since then Ingress enough even the otherwise very large battery of Nexus 7 much longer. Before surgery #cassandra therefore still needed a larger battery pack. The article was there within 2 days and is perfect. In terms of size, it fits into the inside pocket of the jacket or (if the jeans are not too tight) in your pocket. The supplied cable has bridged the two data lines in the connector so that the phone or tablet noted that it can properly draw power here and not only 500mA, otherwise provides USB. The pity is that this bridge was not made in the socket on the battery pack itself, so you can not load at full power with USB data cables. But these are luxury problems that have all battery packs. Would it be different here, I would paint a sixth star on the screen.
