Battery .. blank screen... switching off - GALAXY S2

[Anonymous]

I believe there are a lot of people having this problem.

Battery is fully charged then I go on a few apps and the next minute my phone screen goes blank and has switched off.  I then turn it back on and the battery is beeping to be charged!

After reading about this on loads of forums I can't believe that it is a battery issue.  My phone has only been doing this in the past few weeks and I've just come to the end of my 18 month Contract (waiting to upgrade to new Galaxy when its out ; P)

I thought I had solved this yesterday as it didn't switch off all day after I updated the firmware through Kies and went into settings>applications and emptied the cache on Ebay and Youtube (after me deciding these were the apps I use the most).  Today .. it has happened again!  I noticed it happened when I did a refresh on the accu weather on my home screen, I'm defo thinking its one of the apps that is playing up!

Samsung and O2 don't seem to be responding to any forum questions on this matter which I find unbelievable!  Please can anyone else advise?! Many thanks

There is an update to XWLPD / ULP7 that was released around June last year, so that's why it's asking you to update.....

[MI5]

It's clearly not happy 😞

Take the update and if no better get it back to O2 for repair.....

Will do. Thank you!!!

Sorry, but after all this it would be pointing to a hardware issue 😞

Ooh can I fix it?!

[MI5]

Probably best left to the pros

I may as well have a fiddle about with it!  I can upgrade anytime

Without JTAG (Sammy test kit) you wouldn't know where to start unfortunately. Short of trying another battery "just in case", it could be anything. I'd be inclined to start with battery and battery connections making sure they are all clean and connecting properly.

Oh I sat here before and cleaned all my connections with some alcohol gel and a cotton bud!

Sammy ?!!! hmmm I'll go google.  I do need to try a new battery but its not worth buying one now.  When I check * # * # 4636 # * # * its tells me the battery is in good health.

Got a load of codes from here:

I noticed on a forum someone mentioned selecting 'GSM' instead of 'GSM/cdma auto' in the network options.  Do you think this would make any difference?!
