hi. thanks for reading. if i'm in my building at work on a high level floor, it constantly switches from 1 bar LTE (pretty much non-existent) to no signal to full four bar 4G and then back again to 1 bar LTE. it's like it does not know what to do, stay on a very crappy LTE or a good 4g and it keeps going back and forth all day so many times i actually have no signal since it's on a LTE that doesn't really work in my building. is this cause for severe battery drainage? i am losing battery on standby quickly. also i know i can turn off LTE but i just wanted to know if this is a cause. *also it's a nusiance to turn off LTE every morning at work then turn it off when i leave but i realize i may have to do this.
