Might I suggest you try batteryGuru? It takes two days to learn about how you use your phone and makes battery adjustments based on that. The best part is that it switches my wifi off if I leave the house and turns it back on when I get to work! Whether it's actually saving me any battery I don't know because I've not had the luxury of the phone going flat yet! Also, if you don't have a wireless charger, turn NFC off and obviously bluetooth. I can't even remember the last time I used bluetooth!
I wouldn't recommend it, look at the reviews on Google Play https://forums.androidcentral.com/e...=com.xiam.snapdragon.app&hl=en&token=OJRelGwF
