I have a iPhone 4s with ios 7.1.2 My wife has a iPhone 4s with ios 5.1.1 We live in Tyndall, Mb and have little to no phone reception. I installed a Wilson whole house booster and the reception improved 100%. Problem is battery life on my phone is about 8 hours if I'm lucky. My wife's phone will last 2 days. We are not heavy users. When we go to our cottage at Falcon Lake, both phones last the same amount of time, which is at least 2 days. Why is it that my phone will not last in Tyndall, but it will in Falcon Lake and there is no change in the amount of time my wifes phone lasts? Both phones are on Wi-Fi at home and the cottage.
