Hey all, I currently have an iphone 4s and I am looking to upgrade to a new phone. The s4 and one screens are too big for my taste, so I was thinking about an s4 mini, xperia sp or xperia zr. I mostly use my phone for surfing and watching movies during the commute. Also the occasional casual game, nothing too fancy. I read in some reviews that the battery life of the s4 mini, especially for those 2 tasks is very good, but I find the phone to be a tad bit too expensive for the hardware it contains (around 390 euros). The xperia sp on the other hand offers better hardware for a much lower price (319 euros), but I am finding statements about the battery life to be very conflicting. Anyone got some experience with this phone? The xperia zr then, it looks very nice, but I am afraid the covers for the usb port and 3,5mm jack are not very solid and will be broken in a month or 2. Anyone got some advice?
