I can't tell if you're being sarcastic, but in case you're not: decent battery life for this phone would be 17-20 hours with 3-5 hours screen-on time, WQHD+, all radios on, no convoluted power-saving measures.
I don't know what your needs are, but for me it's sufficient to get through the day (16 hours) on a single charge after recharging overnight. I actually don't need even that much, since I have a wireless charger on my desk and an adapter in my car, so my phone is seldom off a charger for more than a few hours at a time.
Some people may need better battery performance than that, but some others seem to treat battery life as a kind of game score that they're obsessed with maximizing, whether or not it serves any real purpose.
