Make sure your Audio Settings are correct. I am not sure if you can turn off your Built-In Speaker and Microphone. Also, make sure you have nothing plugged into the Headphone Jack.

Else, try updating your Phone Software to the latest version, available here:
http://www.sonyericsson.com/update/?lc=en&cc=gb

Select Xperia X10 from the list and download the software update.
You must plug your Xperia X10 into your PC using a USB cable to perform the update.

I’m happy to help further over the phone at https://www.6ya.com/expert/jeremy_69f3cc28d95bf514

I also have an xperia x10 with the same problem - i've updated from 1.6 to 2.1 with no issues back when 2.1 first came available. Now updating to 2.3 causes the same symptoms as the origonal poster.

Any help would be great

resetting to factory settings your phone may fixed the problem but please be aware that all your recently data or contacts may be delete.

Hi,
As far as I discover ,up to now, the battery life of the Sony Ericsson Xperia X10 smartphone has been kept under wraps. The official product page is just left blank under the battery performance section. However, with the news of the handset launching in Japan, the official SE Japan site does reveal this juicy information. Given its 1GHz Snapdragon chipset and 4-inch screen, I wasn't putting too much hope in decent battery life, but it's looking reasonably okay.
Talktime with 3G networks should last for 4 hours and 50 minutes, whilst a 3G standby time of 200 hours is quoted. Obviously official numbers are always inflated, but at least you'll hopefully be able to get a good days use out of it before having to re-charge.
Just for your own test;
On the dialler press * #*#4636#*# * and under battery history make sure that your phone is sleeping when you are not using it. (Time spent not sleeping)
If its at 100% then an app you've installed is preventing your phone from sleeping. I think the latest firmware fixes the issue
Please switched off the auto screen brightness and set it manually at about 75% which should shorten the battery life but so far no.
A free program called TaskKiller will definetely help to close the .apps draining battery...
