Predicting the battery life of a smartphone https://www.bestadvisor.com/android-phones , based only on technical characteristics, is impossible. It depends not only on the capacity of the battery, but also on the “gluttony” of the filling, resolution, screen brightness, type of its matrix, optimization of the device and, of course, the mode of its use. That is why we check the running time and test the autonomy of smartphones using the same methodology. It would be wrong to call a specific value for the battery capacity and say that it is optimal. But still we can give you approximate guidelines for phones, based on the screen diagonal:

for a smartphone with a display of up to 4 inches, we recommend a battery capacity of at least 1400-1500 mAh;
for a diagonal of 4-5 inches you will need a battery from 2000 mAh;
with a screen from 5 to 5.5 inches - at least 2400 mAh;
For displays larger than 5.5 inches, a battery of at least 3000 mAh is required.
