Thanks for posting, this does sound a little strange. I've checked the 2 postcodes and can see that there should be 3G signal at both locations, however 5JL is predicted to have stronger coverage than 5LR.
As for why this is affecting your battery, it could be that you're not picking 3G signal up at all at 5JL and so are on the 2G network. If so, then this would explain why the battery lasts longer there because being connected to 2G uses less battery than being connected to 3G.
If you would like to check on any other coverage, then please take a look at our UK Coverage Checker.
