As I posted in the ios 7 thread, my 5s battery is draining much faster after 7.1. At work I get no signal, but I didn't have to put my phone in airplane mode. It would go from 97% to 80% over a 9 hr day with an hour or so of music use with no signal. Now location services is constantly on, battery drained to 50% just sitting on my desk, using the same settings as 7.0.6. Now it looks like I will have to put it into airplane mode as it is constantly searching for a signal and running location checks that it did not do in 7.0.6.
