I bought my new htc sensation xe phone on March ,2012. In the starting days mobile is very good with it's performance, after some months HTC gave the software update from android v2.3(ginger bread) to v4.0.3(ice-cream sandwich). From there on the problems started with my phone, all of a sudden many apps started running in the background causing the mobile slow down drastically. The problems started on increasing daily some of them are:
lagging process, taking so much time to respond ie., when I tapped on the call button it would take more than 10sec to make a call, in every aspect same is being repeated. There are two more problems started nowadays, first is the mobile hanging, due to this problem I have to remove the battery and insert again and power on the mobile, it is a time taking process and when I'm in work I'm totally done. The second problem and most important problem is the battery backup, in the starting days there is good battery backup which lasts for minimum 12hrs approx. and now if I use it continuously then maximum 4hrs. There are many more problems with this phone.
