Xperia S data connectivity problem

[m_krishnasainat]

hey this is kris,

my xperia s has a problem with connecting to the internet when i stop using it for a while. when i keep the phone locked for say about 10minutes and then unlock it, the mobile data gets disconnected and the net wouldn't work until i restart mobile data or restart the phone.

can anyone help me out with this annoying problem?

Same problem for me too. However I have narrowed it down to be more related to having the wifi enabled and connected to a router, and then leaving the area of that wifi network without first switching the wifi off on the phone. eg, being at home connect to my home router, and then leaving to go to the office.

I have no power save apps running, not even the pre-installed one, ICS build is 6.1.A.0.453.

Hi again,

I have tried something today and i was connected to the internet/had data all day. What i did was i made the inbox check frequency every 15 minutes. This means that the phone has to use data every 15 minutes. I know this isnt very efficient, however it did stop the problem. I have also only tried it one day.

I too have tries something, after having changed the e-mail check frequency.

Last Thursday I removed the "Set mobile data limit" check box under data usage section in settings.

This pushes the red limit bar right to the top of the chart.

Since doing this, I have gone in and out of using 3G/HSDPA and configured wifi profiles without any actual data connectivity issues, i.e. having a data connection but not actually being able to request Internet data via a browser or app.

If you try this, let the thread know how you get on.

How did you remove the default power saver app?

Me too. I have the problem. Flight mode doesn't help. Restart helps. Happens about after 24 hours after previous reboot. There's no way to notice this, except that you don't get any new notifications. I'm ready to provide additional information - just send me instructions.

And it didn't happen in the beginning. Might be related to ICS update. I currently have 6.1.A.2.45.
