You cannot upgrade to 2.3.7 because that is already there out of the box.
As for what you can do, you can start by reading the EXISTING threads instead of spamming.
Upgrade to the .73 firmware, it resolved it.

You're not understanding - scroll lower, you will see a BUILD NUMBER. Mine is 6.0.A.3.73
The earlier .62 and .67 builds had horrible battery life due to the com.sonyericsson.wakeup service.
If you do not have .73 available in your region, look on the XDA forums for ways to flash it.
