I have been experiencing a huge downgrade on the battery life and phone performance since the latest updates, to the point we're the phone was unusable and very slow. I tried the software repair utility with Xperia Companion but right now I don't have any ringtones on my phone. There are simply no ringtones and I still experience a little bit of battery consumption. At this point I barely have any other apps installed. Please could anyone help me with this.
