I find my phone next to the bed all night (alarm clock) kills the battery. 5 feet away on the table and it's fine. Each phone and network have a different scheduled time for searching out signal, between a few minutes to 10 minutes. This is why your battery dies quicker when you have less reception and much quicker when you have none - on the tube turn plane mode on. My kitchen has an RSJ in the middle of it. One side and I have full reception and long battery life. The other and I often have no reception and a flat battery. You can be as careful as you like with apps and settings, but if that isn't the problem, check the indoor coverage for your network. I used to run a phone shop and am talking from experiance ;-)
If you are on Orange or T-mobile, you can share the others network. In reality, your phone keeps swapping between them using the stronger signal which kills the battery, but gives you beter coverage.
