I have a Sony Xperia U running Android 4.0.4 ICS. The problem is that it runs really slowly. It is particularly bad while multi-tasking. While listening to music, if I get a phone call, it hangs. Vibrator starts but the ringtone doesn't. The "Incoming Call" screen doesn't come up, etc.
Has anyone used this phone with Gingerbread? If so, how was their experience?
I followed the steps in here, but my Battery Monitor says 43% Screen and 23% Android OS, which isn't really helpful! Are there any particular apps that are responsible for this?
Why is ICS slow on this device? I mean, 1.0 GHz dual core and 512 MB of RAM is not less!
edit: The first thing I did after buying it was to upgrade it to ICS via Sony PC Companion. The phone has been like this ever since. I phoned Xperia Support and also did a Firmware Repair (again via PC Companion) and a Factory Reset, but it's no use.

如果从头开始缓慢，你既不指定，如果你可能会在背景中自动运行的太多应用程序超载它（你可能想要的太多应用程序） Izzy 2013-07-06 13:00:49Z, License: CC BY-SA 3.0
谢谢@izzy，但我的手机没有植根，我经常擦除应用缓存！ gunner 2013-07-06 13:08:34Z, License: CC BY-SA 3.0
这听起来很熟悉，简而言之，IC在Xperia系列的设备上，最终爬行到缓慢（有Xperia Mini 2011型号），到底我必须解锁它，并闪现一个新的ROM到它，它足够普通在2011年的设备上有姜饼并升级到ICS t0mm13b 2013-07-06 14:30:08Z, License: CC BY-SA 3.0
You neither specified if it was slow from the beginning, nor did you say if you maybe overloaded it with too many apps automatically running in background (you might want to Izzy 2013-07-06 13:00:49Z, License: CC BY-SA 3.0
Thanks @Izzy, but my phone isn't rooted, and I regularly Wipe App Cache! gunner 2013-07-06 13:08:34Z, License: CC BY-SA 3.0
This sounds familiar, in short, ICS on the Xperia line of devices, do eventually crawl down to slowness (have Xperia Mini 2011 model), in the end I had to unlock it, and flash a newer ROM on to it, its common enough on those 2011 devices that had gingerbread and upgraded to ICS t0mm13b 2013-07-06 14:30:08Z, License: CC BY-SA 3.0
