I just got a note 4 and I love it. Everyone raved about the battery life however and I'm not seeing this great long battery life. I've looked and sometimes the cell standby uses a ton of life. I've read up on that and from what I can understand (I'm not techy at all) the percentage it lists isn't all that accurate but nonetheless I will hit sorting like 18%, get the battery warning pop up, I'll hit ok and it will immediately go to 1% then turn off. My question is 1) is there a way to turn cell standby off? Where we live we only have WiFi calling (thanks for saying we had Excellent coverage in our area tmobile ) so I feel like the cell standby is redundant. If we leave I can switch or whatever but just wondering if there's an option. And 2) any other ways to preserve battery? My screen timeout is the lowest possible. I keep trying the auto brightness but it's often way too dark and I end up squinting to read. TIA!
