Will an iPhone's battery drain faster in places with a poor wifi signal (or phone signal)? My bedroom is far from the wireless router, usually the signal is very weak and flickering, but I have to discover, that after waking up from sleep my battery lost around 25 % for 7-8 hours, while actually I don't do anything with my phone, but it takes more energy than average when idle.
