I have a friend who told me tonight that she’s driving about 400 miles tomorrow. She has to pass trough West Virginia. Parts of WV have poor cell phone reception. She claims that if she starts out with a fully charged phone, by the time she gets to the end of her journey, after 7-8 hours, not talking on her phone more than perhaps 10 minutes during the trip, her phone is basically down to one power bar–discharged. Her explanation is that someone told her the phone spends so much time searching for a tower, that it uses too much power.
I call bullshit. Can anyone give me a reason why this might be true?
