I always had bad battery life at work, no 4G towers nearby, so I would turn off 4g while at work. Now there's a new tower just down the street, I have great 4g, and battery life is still horrible. I notice phone signal is at 96, it's usually bad here, whereas it's 78-82 when at home, with great battery life. So is my problem that there's bad phone signal here (?) and would going back to disabling 4g help? Thanks.
