Habe mir NEN new battery bought because it has simply not done original battery, this was almost 2 years old ... a huge difference, this battery has the next 3 months kept super with me, about one and a half days at high utilization , ie WLAN and Mobile always on until I had to recharge it data. only three months because I've bought myself a new phone. But now that I no longer need the old Xperia U, I have tried, how long does the battery when it's just lying around and only mobile on is: all the 6 days. Top!
