Hi

I'm reading all the "solutions" to what seems an ever increasing problem with Sony phones.. First led charging light stopped working,speakerphone while on call stopped working then battery started going stupid,dropping charge from 98 down to 20 etc, plugging back in then going back up to 98.. Then the fun really started with phone just turning off.. No matter what you do can't turn it back on unless it's being charged..  Tried power/volume buttons. Tried the yellow button near sim card. Got a new sim,got a new sd card. Got a new Sony battery installed. Installed pc companion on pc,backed up everything then tried software "repair".. Set the phone back up, things looking good for about half hour..  Now it just switches off again whenever it wants.. Phone is near full charge...  I'm so frustrated with this piece of junk phone..  Why didn't Sony send through some kind of update to fix what is obviously a very common problem.. This had been going on for years by the look of these threads

I suggest you to check your source of power is established well while charging or not aslo check cables and everything could make the charger randomly plug in and out... Make sure your phone charger is not pluging in and out during recharge. Because it causes the mobile to get a fake charge status... This causes the mobile turn off...

Thanks for reply 

That is not the problem.. The phone is charging fine.. The lightning bolt is on in the battery status. I check it regularly whilst its charging. The phone just shutsdown! The only way I can turn it back on is to plug it back in..  ( to charger or power bank) when it comes back on the battery level is the same as when it went off..weird thing is the date though.. That is set to 1st January 1970...

Then I suggest you to visit your local care team and ask them to put the phone under test to discover the problem.. This process will take 3 to 5 days maybe.

Thanks Aljeraisy 

Any idea of what a care team might be?  Is that a Sony shop? Of course I've taken it back to my phone dealer (optus)..  They say this happens to Sony phones a lot..  always problems.. Taken it to local phone repair man, he slugged me for new Sony battery.. I'll google Sony phone repairs?

I meant go to the official sony repair shops.

Thanks Aljeraisy

I'll google them..  Hope they can sort this out.. Trying everything I can.. Seems like a common problem.. Ready to smash this piece of junk.. Thanks
